Should AEO Have Its Own Budget Line or Come From the SEO Budget?

Why not simply move money from SEO to AEO?

• Most of the work is shared. Rewriting a page so it answers a buyer's question clearly helps search rankings and AI answers alike. Counting it twice, or moving it between budgets, adds confusion but not results.
• Search still feeds AI answers. Google's AI Overviews and AI Mode draw on Google's index, and other assistants rely on search indexes too. Cutting SEO to fund AEO can weaken the foundation AEO depends on.
• AI referral traffic is still small for most sites. Forrester reported AI-generated traffic at 2% to 6% of B2B organic traffic in 2025, though growing fast. A large, separate AEO budget judged on traffic alone would look poor.
• But influence is not just traffic. SparkToro estimated that 68% of US Google searches in early 2026 ended without a click. G2 found 82% of B2B software buyers had sourced recommendations from AI chatbots. Visibility in answers matters even when clicks do not follow.

What goes wrong with each approach?

The last approach is the least exciting and the easiest to defend, which is usually what a new budget line needs in its first year.

How should activities be split?

"Tagged" means the spend stays with its owner, but the portion aimed at AI answers is recorded, so total AI-related investment can be reported without moving money around.

How big should the separate AEO line be?

Two surveys give rough benchmarks. Fractl's survey of 343 US marketing decision-makers, reported by Digiday in August 2026, found that on average about 24% of search or content budgets go to AI visibility, and 82% allocate at least some. Conductor's April 2026 survey of more than 250 enterprise digital leaders found an average of 12% of digital budgets went to AEO in 2025. Both figures include content work this page keeps in the SEO line, so the separate AEO line itself can be much smaller. Size it as a test. A practical starting point is a small share of your search budget, enough to cover:

• One tracking tool, or a manual process with enough prompts and runs to be meaningful.
• Analyst time to build the prompt set, run tests and read results, often a few days a month.
• A fixed amount for source fixes and outreach, such as correcting publisher tables, updating profiles and pitching lists.

Run it for two quarters with agreed measures, then decide whether to grow it. How to decide which pages to move effort toward is covered in how to decide whether to shift SEO budget from blog content to pages AI assistants cite.

How should the AEO line be judged?

Agree the measures before spending:

• Visibility: appearance and recommendation rates on a fixed prompt set, with ranges and controls.
• Accuracy: the share of answers that describe you correctly on prices, features and policies.
• Source coverage: how many of the most-cited sources in your category include you.
• Business signals: AI referral sessions, leads that mention AI assistants, and win-loss interview evidence.

Judge trends over quarters, not weeks. Separating the effects of SEO work from AEO work is covered in how to tell whether AI visibility gains came from SEO or AEO.

When should AEO get more money?

• When AI answers matter visibly to revenue: buyers mention assistants in sales calls, AI referrals convert well, or lost deals trace back to AI recommendations.
• When accuracy problems cost money: wrong prices, wrong features or false claims that sales and support keep correcting.
• When your category's answers rely on sources you can influence, such as review platforms and publisher lists where you are missing.
• When the test shows movement beyond run-to-run noise on the agreed measures.

Grow the line in steps, and keep the shared work in the SEO budget.

Who should own it?

Usually the SEO or search lead, since the skills and data overlap. Where PR, product and support are all involved, name one person to own the AEO line and its reporting. Hold short monthly reviews with the teams whose tagged spend contributes. Without a single owner, AEO work tends to fall between teams.

What might an illustrative case look like?

Consider an illustrative software company with a monthly search budget of $30,000. The marketing director wanted to "move a third of it to AEO". Instead, the team kept content and technical work in the SEO line. It created a $4,000 monthly AEO line for a tracking tool, analyst time and source fixes, and tagged part of the PR retainer as AI-driven outreach. After two quarters, recommendation rate on its fixed prompt set had risen from 14% to 22%, beyond its noise floor. Three lost deals had been traced to a competitor's comparison table, since corrected. The AEO line was raised to $6,000 for the next half.

What do people ask about AEO budgets?

Is AEO just SEO under a new name?

Largely overlapping, but not identical. Measuring AI answers and fixing the sources they cite is new work that SEO budgets rarely cover.

Should agencies charge separately for AEO?

Only for work that is genuinely separate, such as tracking, testing and source fixes. Charging again for content already in the SEO scope is double counting.

Can small businesses skip a separate line?

Yes. A few hours a month of manual testing and fixes, taken from existing marketing time, is enough to start.
