AI search engine optimization: the best options and the companies that offer it

AI search engine optimization is the work of getting your brand named and cited when people ask ChatGPT, Perplexity, Gemini, Claude or Google AI Overviews for a recommendation. You can do it yourself with free checks, use an AI visibility tool, add an AI module to your SEO suite, or hire an agency. LLM Scan is the tool route: a free scan of whether AI crawlers can read your site, then a weekly report of what assistants say about you, with fixes.

We make LLM Scan, so read this with that in mind. Other vendors' prices are only the ones we read on their pricing pages on 7 October 2026; check their sites for current coverage and pricing.

What are the best options for AI search engine optimization?

There are four options for AI search engine optimization: do it yourself with free checks, use an AI visibility tool, add the AI module of the SEO suite you already pay for, or hire an agency or consultant. For most companies the best option is a free readiness scan first, then an AI visibility tool that asks assistants your buyers' questions every week and tells you what to fix. LLM Scan does both, from $19 per month with a 14-day trial; an agency makes sense when you want someone else to do the content work.

The options, side by side

Each option answers a different question. Most teams start with the free one and add measurement once the site is readable.

Which companies offer AI search engine optimization?

Three kinds of companies offer AI search engine optimization. AI visibility software vendors, such as LLM Scan, Otterly.AI, Peec AI, Profound and AthenaHQ, sell the tools to measure and improve how assistants talk about you. SEO suites, such as Semrush and Ahrefs, add AI visibility to their existing products. Agencies and consultants sell it as a service, usually on one of those tools.

How LLM Scan does AI search engine optimization

LLM Scan is software, not a service: you set it up once and the work arrives every week.

  1. 01

    Check that AI can read your site

    The free scan reads the raw HTML your server returns, the way GPTBot, ClaudeBot and PerplexityBot do, and checks robots.txt for AI crawlers, llms.txt, sitemap, structured data and content signals. No account needed.

  2. 02

    Ask assistants your buyers' questions

    Paid plans ask ChatGPT and Perplexity your category and comparison questions every week (Claude and Gemini on Enterprise), and check your Google keywords for rank and AI Overview citations.

  3. 03

    Get the fixes

    The Playbook turns lost questions and missing citations into a ranked list of actions, and Content Machine writes briefs for the pages worth publishing. MCP access lets an agent pick them up.

  4. 04

    Read what moved

    The weekly report shows mention rate and position by assistant, prompts won and lost, share of voice against your competitors, cited sources and 3 suggestions.

What we learned doing it on our own sites

  • This page exists because our own Content Machine found that llmscan.dev was not among the sources Google AI Overviews cite for "ai search engine optimization". We track llmscan.dev and gorilli.io, the site of Gorilli, the company that builds LLM Scan, every week with the same product.
  • AI crawlers do not run JavaScript. When we added crawler tracking to our product, a browser script recorded only human visits and never one AI crawler, so the scan reads raw HTML and crawler tracking runs on the server.
  • A cut-off answer is not a lost answer. In a review of our own runs, ChatGPT answers stopped at the list intro were being scored as "no mention". Now incomplete answers are retried once and then stored as failed: a failed query counts as no data, never as zero mentions.
  • A brand is more than its domain. Mentions are matched on the brand's names and aliases, and every win or loss stores the answer text as evidence, so you can check the score before acting on it.

AI search engine optimization: questions and answers

What is AI search engine optimization?
The work of getting your brand named and cited in answers from ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews: let AI crawlers read your site, publish pages that answer your buyers' questions, and track whether assistants mention you.
Is AI search engine optimization the same as GEO?
Yes. AI search engine optimization, AI search optimization, generative engine optimization (GEO) and answer engine optimization (AEO) are names for the same work.
What are the best SaaS generative engine optimization tools?
For a SaaS company, a tool that measures AI answers every week and ties them to fixes. LLM Scan combines a free readiness scan with weekly tracking from $19 per month; Otterly.AI and Peec AI track daily; Profound and AthenaHQ aim at larger programs.
How much does AI search engine optimization cost?
The readiness checks are free. AI visibility tools start at €29 to €85 per month for Otterly.AI and Peec AI, and $19 per month for LLM Scan. Agencies price their own services.
How long does it take to see results?
Readiness fixes such as robots.txt rules or an llms.txt can ship the same day. Mentions and citations take longer, because assistants refresh their sources on their own schedule; that is why the answers are measured every week.
Can anyone guarantee that ChatGPT will recommend my brand?
No. Assistants change their answers and draw on many sources. AI search engine optimization improves the odds and measures the result; nobody can guarantee mentions or citations.
