How much to budget for AI search visibility (GEO) in 2027: sizing the five lines and finding the money
There is no published benchmark for how much B2B companies spend on AI search visibility (GEO) yet, so size the 2027 budget bottom-up: fix the buyer questions that start your deals, measure how often AI assistants name you against competitors, and fund five lines (measurement, answer-first content, third-party authority, technical and data, profile governance) to close the gaps that matter. For most enterprise B2B teams, most of the money is moved from overlapping SEO, content and PR work, with a 90-day pilot and written go or no-go criteria before the full-year line is approved.
Key takeaways
Why does AI search visibility need its own line in the 2027 budget?
Generative engine optimization (GEO), also called answer engine optimization, is the work that makes AI assistants such as ChatGPT, Gemini, Perplexity, Copilot and Google’s AI features name and cite your company when buyers ask about your category. It overlaps with SEO, but it is judged differently: on whether you are named in the answer, not only on where a page ranks.
The budget case for 2027 comes from the analysts and from buyer behavior. Forrester’s 2027 Budget Planning Guides, published July 15, 2026, list brand visibility in answer engines among the areas marketers should increase. The CMO Survey, fielded in January 2026, found GEO used by 4 in 10 companies. On the buyer side, G2’s April 2026 survey of 1,076 B2B software buyers found 51% start their research with an AI chatbot more often than with Google; G2 is a review platform with a commercial interest in the topic, so read that as directional.
Traffic is moving too. Demandbase reported ChatGPT-referred visits to B2B websites in its customer base rising 303%, from about 645,000 a month in June 2025 to 2.6 million in June 2026. The volume is still small next to search, which is exactly why the line should be sized with care rather than copied from a vendor proposal.
Is there a benchmark for how much to spend on GEO?
Not yet. None of the 2026 budget surveys we checked publishes a share of budget for AI search visibility. The figure most often quoted, Gartner’s finding that marketing leaders put 15.3% of their budgets into AI, covers AI initiatives in general: tools, automation, content production and more. Using it to size GEO would overstate the line many times over.
Our recommendation is to size the line from the gap you can measure and the work it takes to close it, then compare the total with what you spend on SEO, content and PR today. If the GEO line is larger than those three combined, the plan is probably buying volume rather than position.
How do you size each of the five lines?
Our enterprise AI visibility strategy and 12-month roadmap sets out the five lines and who owns them. This table adds the sizing driver for each, so the budget can be built and challenged line by line.
| Line | What it buys | Sizing driver | How to cap it |
|---|---|---|---|
| Measurement | A fixed set of buyer questions tracked monthly across the main assistants; AI-referred traffic and pipeline in analytics and the CRM | Number of questions times assistants times frequency, plus analyst hours to read it | A fixed question set (30 to 50 is enough for most) and a monthly cadence |
| Answer-first content | Rewriting and creating the pages assistants quote: category, comparison, alternatives, pricing, integrations | Pages in the gap list times hours per page | Only pages tied to a tracked question you are losing |
| Third-party authority | Digital PR, analyst and partner listings, review programs, community presence | Sources assistants cite for your questions where you are missing | Named target sources, reviewed quarterly |
| Technical and data | AI crawler access, server-rendered content, structured data, consistent company facts | One-off fixes plus a small maintenance retainer | A fixed scope from an audit |
| Profile governance | Who edits official profiles, approvals and the record of changes | Hours for owners and legal review | Part of an existing role, not a new hire |
If you have not measured the gap yet, start with an AI visibility audit against your competitors. It is the cheapest line and it decides where the rest of the money goes.

Worked example: a company with a $10M marketing budget
This is a worked example with stated assumptions, not a benchmark, a quote or a client result. Every unit cost below is an input you replace with your own rates or vendor quotes.
| Line | Stated assumption | Annual cost |
|---|---|---|
| Measurement | 40 buyer questions tracked monthly with a tool at an assumed $1,000 a month, plus 6 analyst hours a month at an assumed $250 an hour | $30,000 |
| Answer-first content: rewrites | 24 existing pages rewritten at an assumed $2,500 each | $60,000 |
| Answer-first content: new pages | 12 new comparison, pricing and integration pages at an assumed $4,000 each | $48,000 |
| Third-party authority | Digital PR and review program aimed at named sources, at an assumed $8,000 a month | $96,000 |
| Technical and data | One-off fixes scoped from an audit | $25,000 |
| Profile governance | Owner and legal review time | $10,000 |
| Total | Five lines | $269,000, or 2.7% of the $10M marketing budget |
| Funded by reallocation | Blog volume replaced by rewrites ($90,000) and PR redirected to cited sources ($60,000) | $150,000 |
| New money | Total minus reallocation | $119,000 |
The structure matters more than the totals. Most of the line is moved from work the company already funds, and the new money is small enough to approve as a 90-day pilot first. Our 90-day AI visibility pilot plan sets out the go or no-go criteria for that first quarter.
Where should the money come from?
- Blog volume: replace a share of new top-of-funnel posts with rewrites of the pages assistants already quote for your category.
- PR: point existing PR and analyst relations spend at the sources assistants cite for your buyer questions, instead of general coverage.
- SEO retainers: fold technical fixes for AI crawlers and structured data into the existing technical SEO scope.
- Review and partner programs: fund review generation on the sites that appear in AI answers for your category, and keep partner listings current.
- AI pilots: Forrester advises cutting AI pilots that lack governance, ownership, success criteria or a path to scale. Money released there can fund a measured visibility program.
How do you show the CFO what the GEO budget returns?
Report three layers, and say which ones you can tie to revenue today. The first is position: share of answer on the tracked questions against named competitors, and the accuracy of what assistants say. The second is traffic: AI-referred sessions in analytics, and the answer to a how-did-you-hear-about-us field that lists AI assistants. The third is pipeline: opportunities from accounts that arrived through AI referrals or reported an assistant as a source.
Our AI visibility KPIs for board reporting article sets out the definitions. For the budget conversation, agree in advance what the pilot must show at 90 days to release the rest of the line, for example a stated gain in share of answer on the priority questions and the measurement in place to see AI-influenced pipeline.
Mistakes we see in GEO budgets
- Copying a share of budget from a general AI statistic instead of sizing from the gap.
- Funding measurement only, so the dashboard is accurate and nothing moves.
- Funding content volume instead of rewriting the pages assistants quote.
- Leaving out third-party authority, the line that most often changes whether assistants name you.
- No go or no-go date, so the line renews by default in 2028.

Frequently asked questions
How much should a B2B company budget for GEO in 2027?
There is no published benchmark yet. Size it bottom-up from your buyer questions and the gap to competitors across five lines: measurement, answer-first content, third-party authority, technical and data, and profile governance. In our worked example for a $10M marketing budget the line was $269,000, mostly reallocated, but your figure depends on your gap and rates.
Is GEO part of the AI budget or the SEO budget?
Plan it as its own line with one owner, funded mostly from SEO, content and PR work it overlaps with. Gartner’s 15.3% of marketing budgets going to AI covers AI initiatives in general, not visibility in AI answers.
Should we increase AI search visibility spend in 2027?
Forrester’s 2027 Budget Planning Guides advise marketers to increase spend on brand visibility in answer engines. Increase it where you can measure a gap on questions that start your deals, and run a 90-day pilot first.
What should a GEO pilot cost?
A quarter of the full-year line is a reasonable first step: measurement, a first batch of page rewrites and a first push on the sources assistants cite, with go or no-go criteria written in advance.
How do I prove GEO spend to the CFO?
Report share of answer on tracked questions, AI-referred sessions and self-reported AI sources, and the opportunities from those accounts. Agree the 90-day criteria that release the rest of the budget.
