The pages AI reads in your field, and your free comparison page

There isn't one agency that's best for every B2B service company. Nearly every "best AEO agency" list online is published by an agency that ranks itself first, so treat those rankings with caution. Blend, Growleads, Optimist, Breaking B2B and Discovered Labs all do this.

Most lists also focus on B2B SaaS rather than service firms like consultancies, professional services or agencies. A few agencies do explicitly cover services:

- Avenue Z (New York) is described as a digital marketing and PR agency specializing in AI visibility, performance media, and brand authority for B2B companies across fintech, emerging technology, and professional services.
- RevenueZen is described as a B2B growth marketing agency specializing in SEO and Generative Engine Optimization for SaaS, technology, and professional services companies, with a focus on tying AI visibility to pipeline.
- Zupo is listed as a fit for B2B SaaS companies, B2B services and consulting firms, and companies in the 'best-of' categories.
- OutreachBloom is described as a fit for growth-stage B2B SaaS and services companies that want AI search visibility and outbound pipeline executed for them.
- Optimist offers consulting-style engagements. Audits, strategy, and roadmap projects start at $2,500, and ongoing AEO advising starts at $3,000/month. That's a lower-cost way to start.

Budgets vary widely. One source says most B2B AEO retainers fall between $4,000 and $15,000 per month for growth-stage companies, with enterprise programs running from $15,000 to $30,000+.

A few things matter more than the agency's name:

1. Measurement. Look for agencies that track citation rates and share of voice in AI answers, not just keyword rankings. Ask how they connect that to leads or pipeline.
2. Integration with SEO. One source argues that Google still drives the majority of organic pipeline for most B2B companies, and any agency that treats AEO as a replacement for SEO is missing the bigger picture.
3. Relevant experience. Ask for case studies from companies like yours, with citations in ChatGPT, Perplexity or Google AI Overviews for the questions your buyers actually ask.
4. Contract terms. Month-to-month or short initial terms reduce risk in a young discipline. Discovered Labs, for example, lists month-to-month contracts.

If you tell me your industry (consulting, IT services, legal, or something else), budget and whether you want an agency or a consultant, I can narrow this down. I'd shortlist 2-3 of the services-friendly agencies above and ask each to audit how you currently appear in AI answers for your top 10 buyer questions.

There's no single best GEO agency. Most "best of" lists are published by agencies that rank themselves or their partners, so treat them as a way to find candidates rather than as verdicts. The same few B2B names do come up repeatedly, though.

Agencies that recur for B2B
- Directive is named in several lists as a B2B-focused option. Its GEO service covers entity and topic mapping, AI content optimization, structured data, AI visibility tracking and authority building. One roundup calls it a fit for established B2B companies that want AI search integrated with performance marketing and pipeline.
- Omniscient Digital suits B2B software with an established content program. It offers GEO and answer engine optimization alongside its SEO and content programs, and its ideal client is a B2B software company with an existing content program. Published pricing runs from $10,000 / mo, though another source lists from $8,000/mo.
- RevenueZen is pitched at pipeline-focused B2B. Its listing says from $3,000 / mo, with a full GEO program from the $10,000 / mo tier.
- iPullRank is the pick for technical work. Roundups name iPullRank or Intero Digital for enterprise technical GEO.
- First Page Sage fits if thought leadership is your main strategy. It is listed as best for B2B companies investing heavily in thought leadership.
- Flow Agency explicitly targets your type of company. It positions its AI SEO and LLM optimization services around B2B SaaS and service businesses.

How to narrow it down
1. Match the agency to how you win deals. One guide says to choose the GEO agency that best matches how your company actually generates revenue. If you're a services firm with long sales cycles and expert-led selling, a content and thought-leadership shop (First Page Sage, Omniscient, Directive) will likely fit better than a link-building or purely technical one.
2. Check that they have solid SEO fundamentals. The best GEO agencies for B2B have a deep understanding of SEO fundamentals. GEO is largely an extension of good SEO, content, and digital PR, so be wary of anyone selling it as something entirely new.
3. Ask how they measure results. Ask for AI citation and share-of-voice reporting across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Also ask how they tie that to pipeline, not just mentions.
4. Ask for B2B services case studies and references. Many examples are SaaS, which behaves differently from professional services.
5. Be skeptical of guarantees. AI answers vary run to run, so no one can promise specific placements.
6. Start with an audit or short pilot. Run a 3-month engagement before committing to a 12-month retainer.

Budget: Expect roughly $3,000-$10,000+ per month for reputable B2B programs. If you're below that, consider keeping it in-house with a GEO tracking tool and a strong content lead.

If you tell me your niche (e.g., IT services, consulting, legal, or staffing), budget, and whether you already have an SEO or content program, I can narrow this to two or three options.

AEO (answer engine optimization) is a young field, and most "top agency" lists are published by the agencies themselves, so treat the rankings with some skepticism. A few names come up repeatedly across independent roundups.

Agencies that appear most often for B2B

- NoGood shows up on nearly every list. It has proprietary AEO tech (Goodie), cross-engine visibility, and data-driven experimentation. It also integrates AEO with demand generation and revenue-focused marketing. One roundup notes it's a better fit for consumer and tech brands that want AEO with paid and social, so it's less purely B2B.
- First Page Sage is early to the space, having launched AEO services in 2023. Its model is AEO tied to thought leadership and lead generation for B2B. Pricing is listed at $10,000+ per month.
- Discovered Labs is an AEO-first agency for B2B SaaS with fast execution and proprietary tracking. It lists pricing from €5,495+/month on month-to-month terms. It publishes one of the lists I found, so that ranking is self-promotional.
- Omniscient Digital suits growth-stage B2B SaaS that leads with content, and offers AI share-of-voice and citation-share reporting.
- Minuttia is a content-led AEO agency for B2B SaaS companies with product-market fit and budget for content at scale, at roughly $4,000+ per month.
- Skale is a B2B SaaS SEO and AEO agency focused on visibility in ChatGPT, Perplexity, Gemini and Google AI Overviews.
- LoudFace combines SEO, AEO, and site development with per-prompt and per-engine AI visibility tracking for Series A to C B2B SaaS and fintech teams.
- Omnius has specialized expertise in fintech and B2B SaaS.
- Graphite focuses on full-funnel content systems with AI-focused SEO integration for B2B SaaS and fintech.

Other options by niche

- iPullRank is best for enterprise technical AEO, with advanced technical SEO and information architecture.
- Animalz is one of the top B2B content marketing agencies, and its content strength carries over to AEO.
- Idea Grove is a B2B PR and visibility agency that suits tech, SaaS and industrial brands that need trust signals around AI mentions.
- Three29 works with B2B firms in construction, manufacturing and professional services.
- RevenueZen is aimed at B2B companies with long sales cycles.

How to choose

- Pick an agency that tracks citation rates and share of voice in AI answers, not just keyword rankings.
- Ask for case studies showing AI citations and pipeline impact. One reviewer cautions that agency site descriptions often describe the agency's work in general, not AEO projects specifically.
- Match the agency to your needs. Content-heavy shops like Minuttia, Animalz and Omniscient suit a content-led strategy. iPullRank suits a large site with technical complexity. PR-driven firms suit brands that need third-party mentions.
- Check contract terms. Some offer month-to-month, while others require longer commitments.

If you tell me your industry, budget

Short answer: Don't treat it as an either/or choice. Most sources say AEO and GEO use largely the same tactics, so for a B2B service company the practical priority is a strong SEO and content foundation, with AEO-style content built on top and GEO-style reputation work running alongside it.

The terms overlap heavily
- One B2B guide says the practical overlap between AEO and GEO is almost total, and both describe making your content trustworthy, structured, and citable by AI systems.
- The terms come from different places. GEO comes from a 2023 Princeton/Georgia Tech paper and is popular in ecommerce, while AEO emerged with featured snippets and voice search and is preferred by B2B agencies and SaaS marketers.
- Some vendors do draw a distinction. One says AEO is about getting your content surfaced in AI answers at query time, while GEO is about shaping what AI systems already "believe" about your brand before anyone asks. Another frames it as AEO helping you get cited for what you are, and GEO helping you get recommended for what you're best at.
- Be a little skeptical of these distinctions. Vendors tend to define each term to match what they sell.

What this means for a B2B service company
1. Start with the foundation. All three disciplines rest on crawlable, indexable, trustworthy pages, and Google says its AI features need no special optimization beyond standard SEO best practices. If your site is thin, fix that first.
2. Use AEO as your content frame. Service buyers ask evaluative questions like "who should I hire for X?" One source argues that AEO is the more useful frame for B2B because buyers ask about vendors, methodologies, and expertise. In practice, that means publishing clear, evidence-backed answers to the questions your buyers ask, with FAQs, comparisons, and structured pages.
3. Invest in GEO-style reputation work. GEO behaves more like PR than technical SEO, so you can't optimize your way in with a plugin or schema tag. It depends on third-party validation: reviews, press coverage, directory listings, and consistent descriptions of your firm across the web. For services, where trust drives the purchase, this matters a lot. One source argues that for B2B buyers researching over weeks or months, ignoring GEO is the costlier mistake.

Where sources disagree on order
- One agency says to build SEO first, since the domain authority and content depth that earn rankings are the same signals generative engines weigh when selecting sources.
- Another recommends GEO first, AEO second, and classic SEO third for $5M-$75M founders. That agency sells AEO/GEO and messaging services, so weigh the advice accordingly.
- A more neutral take is that the mistake is treating them as competing budgets instead of one strategy with three surfaces.

A practical sequence
1. Make sure the site is technically sound and your core service pages are clear and specific.
2. Add answer-style content, such as FAQs, comparison pages, pricing or process explainers, and case studies with real numbers. The Princeton study reportedly found statistics lift citation by 41% and named expert quotes by 28%.
3. Build off-site credibility through reviews, industry publications, partner pages, and podcasts or guest content.
4. Test by asking ChatGPT, Perplexity, and Google AI Overviews the questions your buyers ask. Track whether and how your firm is mentioned.

If you only have budget for one thing, spend it on the shared foundation: clear, authoritative content plus third-party credibility. That helps with SEO, AEO, and GEO at once.

There's no single "best" agency. Nearly every ranking I found was published by an agency that ranks itself first, so treat them with caution. Still, a few names come up across many independent lists.

Agencies that appear repeatedly

- Omniscient Digital (Austin) shows up on almost every list. It started as a strategic content marketing agency and expanded into generative engine optimization. One roundup lists full-service retainers from $10,000/month, covering content, technical SEO, and PR.
- First Page Sage is often cited as an early GEO adopter. One list puts it at $8,000+/month, with clients including Okta, Salesforce, and Verizon.
- Directive Consulting suits teams that want GEO tied to paid media. It fits B2B teams that want GEO and SEO inside a wider acquisition program covering paid, research, and revenue ops.
- Animalz is a content-focused agency. It has woven AEO and GEO through its content programs for B2B SaaS.
- Obility is B2B-only. It specializes in revenue attribution and complex enterprise technology sales cycles.
- Discovered Labs is a dedicated AEO/GEO shop. One list shows pricing from €5,495/month on month-to-month terms.
- Others mentioned: iPullRank (technical implementation), Powered by Search (high-ACV, sales-led B2B), Siege Media (content plus digital PR), and RevenueZen.

Caveats

- Most lists are SaaS-focused. Very few address professional or B2B services firms such as consultancies, IT services, legal, or financial services. Ask any agency for case studies from businesses like yours.
- The rankings are self-interested. The ABM Agency's list ranks the ABM Agency #1, First Page Sage's ranks First Page Sage #1, and Obility's ranks Obility #1. Another list rates Obility's AEO/GEO capability as "Low", which shows how much these assessments vary.
- The field is new. Some agencies were founded very recently, and many are traditional SEO shops adding GEO as a service line.

How to choose

1. Ask how they measure success. One guide advises choosing an agency that tracks citation rates and share of voice in AI answers, not just keyword rankings. You also want pipeline or revenue attribution, not just visibility.
2. Ask for evidence from your niche. Request references and results from B2B services clients specifically.
3. Check contract flexibility. Month-to-month terms lower your risk while the discipline matures.
4. Match the agency to your gap. Content-heavy firms like Omniscient and Animalz suit teams that need thought leadership. Directive suits teams that want paid and organic working together. Technical shops like iPullRank suit sites with structural problems.

If you tell me your sector, budget, and whether you already have an SEO or content team, I can narrow this to two or three realistic options.

Short answer: Probably yes to a combined approach, but not necessarily to a *separate* agency. The "combined" part is the right instinct, and whether you need an outside agency depends on your situation.

Why combined makes sense

AEO and GEO are largely the same discipline under different labels. GEO is also known as answer engine optimization (AEO) and artificial intelligence optimization (AIO). Where people do distinguish them, the split is one of scope. AEO targets being the cited source inside an AI answer, while GEO targets influencing the broader generated response and how the model frames your brand. Another source notes that the underlying optimization principles overlap. Splitting them across two vendors would mostly create coordination overhead.

Both also sit on top of SEO. SEO gets you into the pool of pages the AI reads, and GEO makes the AI choose you over competitors. Google itself argues that optimizing for generative AI search is optimizing for the search experience, and thus still SEO. So the best fit is usually an agency that does SEO, AEO and GEO together, not a standalone "GEO-only" shop.

Why it matters for B2B services

GEO isn't only about your website. AI engines assemble narratives from third-party mentions, reviews, forums and publishers, so visibility depends on where and how others validate you. For a services firm, that means case studies, analyst and review-site presence, podcasts and guest content, and consistent entity information. This is closer to PR and content strategy than to technical tweaks.

Caveats

- The field is new and hype-heavy. Terminology and tools are inconsistent, and there's no established standard for measuring results. Treat "guaranteed AI rankings" claims as red flags.
- Much of the work is not agency-exclusive. Answer-first content, schema, clean entity markup and original expertise can be done in-house if you have a decent content or SEO person.
- Measurement is imperfect. AI answers vary by query and session, so ask how an agency tracks progress (share of citations across a fixed prompt set, referral traffic, pipeline influence), not just "mentions."

When an agency is worth it

- You have no in-house SEO or content capacity.
- You need third-party and digital PR work, which is hard to build internally.
- You want a structured baseline audit of how ChatGPT, Perplexity, Gemini and AI Overviews currently describe you.

When to hold off

- Your core site, positioning and content are weak. Fix the foundations first.
- Your existing SEO agency or team already offers this (many do).

How to vet one: Ask for B2B case studies with before/after citation data. Ask what they do beyond reformatting content (third-party presence, original research). Prefer month-to-month or short initial terms. Avoid anyone who treats AEO and GEO as two separate upsells.

If you tell me your approximate budget, team size and sales cycle, I can suggest whether to go in-house, hybrid or fully outsourced.

There isn't one objectively "best" agency. Nearly every "best of" list I found was published by an agency that ranks itself first, so treat the rankings with caution. Here is what stands out for B2B service companies specifically.

Agencies that come up repeatedly

- First Page Sage works primarily with professional services firms, B2B companies, and enterprises seeking sustained organic authority. That makes it a natural fit for service businesses. Its GEO approach centers on list placement and reputation, so site architecture and paid-media alignment may fall outside its scope.
- Directive is often pitched at enterprise B2B. One roundup describes it as the best fit for B2B SaaS teams that want GEO and SEO to sit inside a wider acquisition program covering paid, research, and revenue ops.
- Flow Agency explicitly positions its AI SEO and LLM optimization services around B2B SaaS and service businesses, which is a closer match to your segment than most.
- Powered by Search is a B2B GEO agency for companies with complex sales cycles. This claim comes from its own site.
- Omniscient Digital offers content, citation engineering and digital PR, with pricing from $10,000/month. Its limitation is that site architecture and internal-link implementation typically depend on client-side execution.
- Breaking B2B is a UK-based agency that works exclusively with B2B and SaaS companies.
- iPullRank and RevenueZen also appear on several B2B lists.

Many of the other agencies in these lists focus on SaaS rather than services, so check whether they have real service-firm case studies.

How to choose

1. Ask how they measure AI visibility. One roundup argues the best agencies show how they measure AI visibility, not just that they offer it. Ask which engines they track (ChatGPT, Perplexity, Gemini, Claude, AI Overviews).
2. Ask for service-firm case studies. Look for results in your category, such as consulting, legal, IT services or agencies, and for pipeline impact rather than citation counts alone.
3. Check scope. Some agencies only do content and PR, while others also handle technical and site work. Decide which you need.
4. Check pricing and contract terms. Retainers generally range from about $5K to $20K+ per month, and some agencies require long commitments. WebFX, for example, requires a six-month commitment.
5. Look at independent evidence. Use client references, G2 or Clutch reviews, and a short paid audit or pilot before signing a long contract.

If you share your service type, budget and whether you need strategy only or full execution, I can narrow this down.

Most AEO (answer engine optimization) agencies charge about $3,000 to $15,000 per month for B2B companies. Sources vary a bit, and most of them are agencies selling the service, so treat the figures as rough.

Typical monthly retainers
- Focused or growth-stage: Growth-stage companies typically pay $3,000 to $8,000 for a focused engagement.
- Full-scope or competitive categories: $8,000 to $15,000 for multi-product or competitive categories.
- Enterprise: Enterprise programs run from $15,000 to $30,000+. Regulated industries and global brands can go higher, $20,000 to $100,000+ per month for full-scope programs.
- Overall range: Most engagements fall between $2,000 and $20,000 per month, with the mid-market sweet spot around $4,000 to $12,000.

Other pricing formats
- Audits: A standalone audit is $1,500 to $5,000.
- Projects: Fixed-scope projects run one to three months of the equivalent retainer, delivered in 4 to 8 weeks. The tradeoff is that there's no maintenance after handoff, so gains can decay.
- Bundling: Most agencies bundle AEO and GEO tactics into a single retainer. GEO is generative engine optimization, which targets the same AI-generated answers.

What drives the price
- The number of pages optimized, the scope of off-site co-citation work, and how often prompts are audited.
- Off-site authority work (digital PR, third-party mentions) is the costly part. Roughly 85% of AI citations come from third-party sources.

Watch-outs
- Quotes under roughly $1,500 a month are almost always rebranded SEO packages with an AEO label.
- Published pricing is rare, and most agencies quote custom after a discovery call.
- Check setup fees, minimum contract length, and what is actually delivered (content volume, schema, PR, reporting).

Budgeting for a B2B service company
For a small or mid-sized firm, $4,000 to $8,000 per month is a realistic starting point. Ask for a scoped audit first, then commit to a retainer. Expect AI citations to take a while to show up: One source says B2B SaaS companies spending $3,000 to $5,000 per month typically see measurable AI citation appearances within 60 to 90 days.

If you tell me your company size, how competitive your category is, and your budget, I can help you work out which tier fits and what to ask agencies in the first call.

Sources vary quite a bit, but most land on early signals within about 1-4 months and pipeline impact within 6-9 months or one sales cycle.

Typical timeline for B2B services

| Milestone | Typical window |
|---|---|
| Baseline and audit | Weeks 1 to 3, followed by a foundation phase (structured data, content build) through about week 8 |
| First brand mentions or citations | Estimates range from 2-6 weeks for brand mentions and basic visibility to 30-60 days for first citations |
| Measurable improvement in AI visibility | Most B2B teams see measurable improvements in AI visibility within 60 to 90 days. Another practitioner reports early citation movement within eight to sixteen weeks, with compounding gains after that |
| Broad visibility across ChatGPT, Perplexity and Google AI | Generally 3-6 months |
| Pipeline or revenue impact | Pipeline attribution typically takes 6 to 9 months, which fits with B2B sales cycles |

What speeds it up or slows it down

- Your starting point. Companies with existing content and domain authority typically see results within 60 to 90 days of structured content updates, while companies starting from scratch may need 4 to 6 months.
- Content volume. One source claims 20+ optimized pieces monthly reaches saturation within 90 days, while 4-8 pieces monthly typically needs 12+ months. This is a vendor benchmark, so treat it cautiously.
- Platform type. Engines like Perplexity and Google AI Overviews pull live data, so structural changes can show results within weeks. ChatGPT's base model updates more slowly, though it can also use live search.
- Off-site authority. Broader visibility in ChatGPT and Perplexity takes longer because it requires building citation frequency through digital PR and content optimization.
- Ongoing effort. GEO performance declines if efforts are paused.

Caveats

- Almost all of these figures come from agencies and GEO vendors who have an incentive to promise quick wins. There is no independent, standardized benchmark yet.
- AI answers are variable, so the same prompt can produce different citations on different days. Track a fixed set of prompts over time rather than relying on one-off checks.
- A sensible approach is to optimize 10-15 cornerstone content pieces, track citation and traffic results for 90 days, then calculate ROI before expanding investment.

As a rule of thumb, expect early visibility signals in 2-3 months, solid presence in 4-6 months, and revenue impact after that.

Short answer: expect early signals in about 2 to 8 weeks, meaningful results in 3 to 6 months, and pipeline impact within one B2B sales cycle.

Typical timeline

- First citations and mentions (about 2-6 weeks): Brand mentions and basic visibility improvements typically begin within 2-6 weeks. Perplexity and Google AI Overviews tend to respond fastest, often within 1-3 weeks, because of real-time indexing and reliance on SEO signals.
- Meaningful impact (3-6 months): Most brands see meaningful GEO impact within 3-6 months. One breakdown puts early citation appearances in months 0-2, rising citation frequency in months 2-4, predictable visibility patterns in months 4-6, and compounding returns after month 6.
- Revenue and pipeline (one sales cycle): One agency says most B2B clients see citation lift in weeks and pipeline impact within one sales cycle. For B2B with 6-12 month sales cycles, closed revenue will lag the visibility gains.

What speeds it up or slows it down

- Faster: Strong existing domain authority, high-quality comprehensive content, and clean technical implementation. Niche topics with less competition also show faster results.
- Slower: Technical barriers such as JavaScript rendering delay results. Broader visibility in ChatGPT and Perplexity takes longer because it requires building citation frequency through digital PR and content optimization.
- Ongoing effort matters: One source warns that GEO performance declines if efforts are paused.

Caveats

Most of these timelines come from agencies and vendors that sell GEO services, so treat them as optimistic benchmarks rather than guarantees. The field is also new, and AI platforms change how they cite sources frequently. Results will vary with your competition, existing content, and how you measure success.

Practical advice when evaluating an agency

- Ask what they will measure at 30, 60, and 90 days, such as citation rate, share of voice across ChatGPT, Perplexity, and AI Overviews, and AI-referred leads.
- Be wary of promises of guaranteed rankings or results in a few days.
- Consider a pilot first. One guide suggests optimizing 10-15 cornerstone content pieces, tracking citation and traffic results for 90 days, then calculating ROI before expanding investment.
