AI SEO Services: What's Included and What They Cost in 2026

AI SEO services are the combined work of making a website citable by AI-powered search tools such as ChatGPT, Gemini, and Perplexity, alongside traditional Google rankings. The term covers four distinct components: technical AI crawler access, Answer Engine Optimisation (AEO), Generative Engine Optimisation (GEO), and citation tracking. This guide covers exactly what each component involves, real 2026 UK pricing, and why most agencies now bill AI search optimisation as a separate line item rather than folding it into standard SEO.

What are AI SEO services?

AI SEO services extend traditional SEO to cover a second surface: the answer layer inside AI tools, rather than only the ranked results page. ChatGPT processes roughly 700 million weekly queries and Google's AI Overviews reach around 2 billion monthly users, so a business invisible in AI answers is losing visibility in a channel that is now genuinely large. IINES treats AI SEO as an extension of standard SEO work rather than a separate discipline, because the same structured, factual content that earns AI citations also strengthens traditional Google rankings.

What's included in AI SEO services?

A complete AI SEO service covers four components. The table below breaks down what each one involves and where IINES delivers it.

Component	What it involves	IINES delivery
Technical AI crawler access	robots.txt directives allowing OAI-SearchBot, PerplexityBot, ClaudeBot, Google-Extended; IndexNow submission to Bing	Visibility Audit
Answer Engine Optimisation (AEO)	Direct answer blocks in the first 150 words, FAQPage schema, question-to-answer content mapping	Implementation Sprint + Revenue Engine content
Generative Engine Optimisation (GEO)	Consistent brand entity signals across directories, press, and review platforms so AI models trust the source	Revenue Engine retainer
Citation tracking	Testing prompts across ChatGPT, Gemini, and Perplexity to record whether a brand is cited, and for what	Included in monthly Revenue Engine reporting

Most cheaply-priced AI SEO offers quietly skip GEO and citation tracking because they are the hardest to deliver and measure. If a quote for AI SEO services looks unusually low, entity-building and reporting work are almost always what is missing.

What's the difference between AEO and GEO?

AEO and GEO are often used interchangeably, but they target different parts of the AI SEO problem. The table below compares them directly.

Dimension	AEO (Answer Engine Optimisation)	GEO (Generative Engine Optimisation)
Where the work happens	On your own website	Across third-party sources
What it covers	Direct answer blocks, FAQ schema, content structure	Directory listings, press mentions, review platforms, entity consistency
Speed to results	Faster, often 2 to 4 weeks after implementation	Slower, typically 60 to 90 days as consensus builds
Where IINES delivers it	Visibility Audit and Implementation Sprint	Revenue Engine retainer

Around 85% of AI brand mentions originate from third-party sources rather than a brand's own website, according to Search Engine Land's 2025 analysis, which is why GEO work matters even for a business with strong on-site content. AEO without GEO gets a website citation-ready; GEO is what actually gets it cited.

How much do AI SEO services cost in the UK?

UK AI SEO pricing scales with how many of the four components are included and how competitive the space is. The table below breaks down what each band typically covers.

Monthly budget	What it typically includes	Best for
£750 to £1,500	Technical crawler access, schema deployment, AEO restructuring on existing pages	Small businesses starting from zero AI visibility
£1,500 to £3,500	Full AEO plus GEO entity building, monthly citation tracking across 3+ AI platforms	Growing SMEs wanting measurable AI search presence
£4,000 to £10,000+	Enterprise-scale AEO and GEO, dedicated prompt auditing, PR-grade citation building	Competitive sectors: legal, finance, SaaS, healthcare

At most UK agencies, this is billed as an add-on to an existing SEO retainer, commonly from around £740 per month, and 61% of UK agencies report they are actively expanding their AEO service offerings in 2026. IINES includes the full four-component service inside every Revenue Engine retainer from £2,100 per month, at no separate charge.

Why does AI search visibility matter for a small business?

AI Overviews now appear in roughly 16% of Google searches and are triggered by around 21% of all keywords, and organic click-through rates fall by roughly 61% when an AI Overview appears above the results, according to industry benchmarking cited by UK agencies in 2026. That drop in clicks does not mean the customer disappeared; it means they got their answer from the AI Overview or asked a chatbot directly instead.

The commercial upside is real. ChatGPT referral traffic converts at around 16.8% and Perplexity referrals at 10.5% to 12.4%, compared to roughly 2.8% for standard Google organic traffic, according to Microsoft Clarity's AI traffic data. A small business invisible in AI answers is not just missing impressions, it is missing a channel that converts considerably better than average organic search once it starts sending traffic.

What technical work needs to happen before AEO or GEO can work?

AI crawlers must be explicitly allowed before any content or entity work can produce a single citation. The most common AI SEO mistake is agencies selling GEO or entity-building work before confirming the site is even crawlable by AI bots.

robots.txt AI bot directives: explicitly allow OAI-SearchBot, ChatGPT-User, PerplexityBot, Google-Extended, and ClaudeBot
IndexNow submission: ping Bing's index on every publish or update, since ChatGPT search runs on Bing's index rather than crawling independently
Schema markup: Article or BlogPosting schema with a current dateModified, plus FAQPage schema on any Q&A content
Clean canonical and crawl setup: duplicate content and crawl blocks undo AI SEO investment before it starts

IINES checks and fixes all four of these during every Visibility Audit, before any content or GEO work begins, because AEO and GEO spend produces close to nothing on a site AI crawlers cannot access.

How long does it take to see results from AI SEO services?

Technical and content-level changes, such as fixing crawler access and adding FAQ schema, can produce citation pickup within 2 to 4 weeks of implementation. GEO and entity-building work takes longer, typically 60 to 90 days, because it depends on third-party sources building consensus around a brand rather than a single on-site change. A realistic 90-day target is moving from zero AI citations to 3 to 5 consistent citations per platform for a given topic cluster. IINES tracks this with a baseline prompt audit at the start of every engagement, testing the same queries a real customer would ask before any work begins.

What red flags should I watch for when buying AI SEO services?

Some warning signs apply specifically to AI SEO, on top of the usual SEO red flags. The table below lists the most common ones.

Red flag	Why it matters
Guaranteed AI citations or rankings	No agency controls what an AI model chooses to cite; guarantees signal risky tactics or dishonesty
No baseline or citation reporting	Without a starting measurement, it is impossible to prove any actual progress happened
Selling GEO before confirming crawler access	Entity-building work delivers nothing if AI bots cannot access the site in the first place
Rebadged traditional SEO as "AI SEO"	Some providers simply relabel standard SEO work without adding AEO, GEO, or citation tracking

Any credible AI SEO provider should be able to show a sample citation report from a real engagement before you sign anything. IINES runs a baseline prompt audit at the start of every Visibility Audit and reports on actual citation tracking, not vanity metrics.

AI SEO Services Questions, Answered

AI SEO services are the combined work of making a website citable by AI-powered search tools such as ChatGPT, Gemini, and Perplexity, alongside traditional Google rankings. This includes technical AI crawler access, Answer Engine Optimisation (AEO), Generative Engine Optimisation (GEO), structured data, and citation tracking. IINES delivers all of these inside its Revenue Engine retainer rather than selling them as a separate service.

AI SEO services typically include technical AI crawler access (robots.txt directives allowing AI bots, IndexNow submission), AEO (direct answer blocks and FAQ schema so AI models can extract facts), GEO (brand entity consistency across third-party sources like directories and press), and ongoing citation tracking across ChatGPT, Gemini, and Perplexity. IINES bundles all four into every Visibility Audit and Revenue Engine engagement.

AEO (Answer Engine Optimisation) is on-site work: restructuring content into direct answers and FAQ schema so AI models can extract facts from your own pages. GEO (Generative Engine Optimisation) is off-site work: building consistent brand entity signals across third-party sources such as directories, press, and review platforms, so AI models trust and cite the brand when generating consensus answers. IINES delivers both as one connected service rather than pricing them separately.

UK AI SEO services typically cost £750 to £1,500 per month for entry-level technical and on-page AEO work, £1,500 to £3,500 per month for AEO plus GEO entity building with cross-platform citation tracking, and £4,000 to £10,000 or more per month for enterprise-scale programmes with dedicated prompt auditing. At most agencies this is billed as an add-on to an existing SEO retainer, commonly from around £740 per month. IINES includes it inside every Revenue Engine retainer at no extra charge.

AI Overviews now appear in roughly 16% of Google searches and are triggered by around 21% of all keywords, and organic click-through rates fall by roughly 61% when an AI Overview appears above the results. ChatGPT referral traffic converts at around 16.8% compared to 2.8% for standard Google organic traffic, according to Microsoft Clarity data. A small business invisible in AI answers is losing a growing, high-converting channel to competitors who are optimised for it.

AI crawlers must be explicitly allowed in robots.txt before any content or entity work can produce citations; a blocked bot means zero visibility regardless of content quality. This includes allowing OAI-SearchBot, ChatGPT-User, PerplexityBot, Google-Extended, and ClaudeBot, plus submitting updates through Bing's IndexNow protocol since ChatGPT search runs on Bing's index. IINES checks and fixes this technical foundation during every Visibility Audit before any content or GEO work begins.

Technical and content-level changes, such as fixing crawler access and adding FAQ schema, can produce citation pickup within 2 to 4 weeks. GEO and entity-building work, which relies on third-party sources building consensus around a brand, typically takes 60 to 90 days to become measurable. A realistic 90-day goal is moving from zero AI citations to 3 to 5 consistent citations per platform for a given topic cluster.

Watch for guaranteed AI citations or rankings, no citation evidence or baseline reporting, and providers who sell GEO or entity-building work before confirming AI crawlers can even access the site. No agency controls what an AI model chooses to cite, so guarantees signal either dishonesty or risky tactics. IINES runs a technical access check before any content or entity work and reports on actual citation tracking rather than vanity metrics.
