Best GEO Tools in 2026: Generative Engine Optimization Tools for Every Step

The best GEO tools in 2026 are the ones that cover the four jobs of generative engine optimization: making sure AI crawlers and Google can reach your pages, writing content an engine can quote, publishing it steadily, and measuring whether engines use it. Start free with Google Search Console's generative AI report and Bing Webmaster Tools' AI Performance report. To audit AI crawler access, use Semrush Site Audit or Otterly.AI. To shape content, use Frase, Surfer or Clearscope. To publish on a schedule, use an agent such as Bottally. To track AI answers in depth, see our list of the best AEO tools.

Prices checked October 2026 on each vendor's own site. Bottally publishes this blog and appears in three places below: its free audit, its paid agent and its free checkers. Tools are grouped by the job they do, free tools first, then by entry price on monthly billing.

If you were looking for GeoTools, the open-source Java library for maps and geospatial data, that lives at geotools.org. This post is about generative engine optimization.

What is generative engine optimization?

Generative engine optimization (GEO) is the work of making your content easy for generative engines to find, read and use in their answers. Those engines include ChatGPT, Perplexity, Gemini, Copilot, and Google's AI Overviews and AI Mode. The term comes from a 2023 research paper, GEO: Generative Engine Optimization, later presented at the KDD 2024 conference.

AEO, answer engine optimization, describes the same goal from the other end: whether the answer names you. In practice, AEO tools mostly measure outputs (mentions and citations), and GEO work is mostly about inputs (crawl access, content, publishing). This post covers the input side. Our AEO tools comparison covers the trackers.

What Google says GEO needs, and what it doesn't

Google published a guide to optimizing for generative AI, last updated July 2026. It is unusually specific, and it shapes which tools are worth paying for.

What Google says matters:

Indexing and snippets. A page has to be indexed and eligible for a snippet to appear in AI Overviews or AI Mode, and your site must be included through Search Console's new generative AI control, which is on by default.
Crawlable content. Keep content reachable, follow JavaScript SEO basics, offer a good page experience and reduce duplicates.
Non-commodity content. Pages with a unique, first-hand point of view, organized with clear headings, with useful images or video.
No page per variation. Creating pages for every fan-out version of a query to manipulate results "violates Google's scaled content abuse spam policy."

What Google says you do not need:

llms.txt and "special" markup. "Google Search itself doesn't use them," and creating them "will neither harm nor help."
Special schema. "Structured data isn't required" for AI features.
Rewriting just for AI, or chunking content into fragments.

Google also notes that "no third-party tool has access to our internal ranking or AI systems." Every tool below estimates; none sees inside the engine.

Google's own summary: "optimizing for generative AI search is optimizing for the search experience, and thus still SEO." Other engines have not published anything as specific, but ChatGPT and Perplexity also search the web before answering, so the same basics carry over.

What are the best tools for generative engine optimization?

By job, as of October 2026:

Audit crawl access: Bottally website audit (free), Semrush Site Audit (from $199 a month for the AI-ready audit), Otterly.AI (from $29 a month), Writesonic AI bot analytics (from $99 a month).
Shape content: Frase (from $49 a month), Surfer (from $59 a month), Clearscope (from $129 a month).
Publish: Bottally ($99 a month).
Measure: Google Search Console (free), Bing Webmaster Tools (free), Bottally AI visibility and AI Overview checkers.

Job 1: Audit whether AI crawlers and Google can reach you

An engine cannot cite a page it cannot fetch. This is the cheapest job to get right, and the failures are often simple: a robots.txt rule, a CDN setting that blocks bots, or content that only renders in JavaScript.

Bottally website audit

The free website audit reads your robots.txt, including whether it blocks AI search crawlers such as OAI-SearchBot, PerplexityBot and Claude-SearchBot (training crawlers such as GPTBot are reported separately). It then finds your sitemap and checks up to 30 pages for titles, meta descriptions, headings, canonicals, structured data, thin content, mobile tags and broken URLs, and lists each fix. It runs in about a minute with no account.

Price: free, no sign-up.
Best for: a first pass on the crawl and indexing basics Google says its AI features depend on.
Limitation: it reads robots.txt rules rather than testing how your server or CDN answers each bot, it does not check llms.txt, and it covers up to 30 pages per run.

Otterly.AI GEO audit

Otterly.AI includes a GEO audit on every plan that tests 19 AI crawlers against your robots.txt and your live server, plus a crawlability and content check.

Price: Lite $29 a month, or $25 a month billed annually, with 1,000 GEO audits a month. 7-day free trial.
Best for: small teams that want AI crawler checks bundled with basic tracking.
Limitation: the audit reports what to fix; the fixing is yours. Otterly removed its llms.txt checker in a February 2026 rebuild.

Writesonic AI bot analytics

Writesonic reads your server logs, through Cloudflare, CloudFront, Vercel, Fastly, Shopify, WordPress and others, to show every AI crawler visit, every click from an AI citation, and every page returning errors to AI bots such as GPTBot, ClaudeBot and PerplexityBot. Its free llms.txt generator builds a file from your sitemap with no login, three files a day.

Price: AI bot analytics is on all paid plans: Starter $79 a month billed annually, or from $99 a month on monthly billing.
Best for: teams that want proof AI crawlers are actually visiting and which pages fail them.
Limitation: you need access to a log source, and the tracking on self-serve plans covers three engines.

Semrush Site Audit

Semrush Site Audit has an AI Search Health score that checks whether AI crawlers such as OAI-SearchBot are blocked by your robots.txt, with a widget covering eight major AI crawlers.

Price: the AI-ready Site Audit is listed on Semrush's SEO and AI Search plans, from $199 a month or $165.17 a month billed annually. A free Semrush plan allows 10 reports a day, and paid plans have a 7-day trial.
Best for: teams already on Semrush who want AI crawler checks inside their usual audit.
Limitation: it flags a missing llms.txt, although Semrush's own testing "didn't find a correlation between implementing llms.txt and improved performance in AI results," and Google says it does not use the file.

Job 2: Shape content engines can quote

Google's guidance points at content with a first-hand point of view and clear structure. These tools score drafts against what already ranks and gets cited, which helps with structure and coverage. The first-hand part has to come from you.

Frase

Frase studies the pages and AI answers that win a query, writes a brief, and gives each draft an SEO and GEO score with fix suggestions. It can publish to WordPress, Webflow, Sanity or Wix, and its hosted CMS adds structured data and llms.txt to every page.

Price: Starter $49 a month, or $39 a month billed yearly, with 10 articles and AI visibility on ChatGPT and Google AI. 7-day free trial, no card.
Best for: writers who want research, scoring and tracking in one editor.
Limitation: Starter caps you at 10 articles a month, and AI crawler monitoring starts on the $129 Professional plan.

Surfer

Surfer's Content Editor gives live guidelines and a content score as you write, and its AI Tracker scrapes real answers from ChatGPT, Perplexity, Gemini, AI Overviews and AI Mode.

Price: Discovery $59 a month, or $49 a month billed yearly, with 120 documents to create or optimize. Standard, which adds 25 AI prompts refreshed weekly, is $119 a month, or $99 billed yearly.
Best for: content teams that write in-house and want a scoring editor with tracking attached.
Limitation: the Discovery plan card lists no tracked AI prompts, and Standard tracks ChatGPT only, weekly. Its log-based Agent Analytics is in closed beta.

Clearscope

Clearscope grades drafts for topic coverage and adds query tracking across ChatGPT and Gemini, brand visibility tracking and what it calls query fan-out awareness.

Price: Essentials $129 a month, no contracts, 14-day free trial.
Best for: editorial teams that want a simple grading tool their writers will use.
Limitation: tracking names only ChatGPT and Gemini, with 50 tracked queries on Essentials.

Job 3: Publish steadily

Engines answer thousands of specific questions. A site that publishes one clear answer at a time, every week, gives them more to cite. It is also the easiest job to let slip, and the one an agent can take over.

Bottally

Bottally researches keywords, audits your site, reads what competitors publish, writes seven articles a week and publishes one a day to WordPress, Webflow, Ghost, Shopify, Wix, Notion, Framer, Next.js or any webhook. It asks ChatGPT, Perplexity, Google AI Overviews and Google AI Mode up to 30 buyer questions every week, and each question where you are missing becomes an article. It also runs an opt-in backlink network.

Price: Pro $99 a month for one site. The Free plan does not publish or track AI engines.
Best for: founders and small teams whose bottleneck is getting pages written and published.
Limitation: it is not a deep analytics suite. It tracks 30 questions on four engines weekly and does not read server logs to show AI crawler visits, so pair it with a log-based tool above if you need that view.

Other agents publish on autopilot too, and they differ on tracking and links; see our comparison of the best AI SEO agents.

Job 4: Measure whether engines use your content

Google Search Console

Search Console now has a generative AI performance report for AI Overviews and AI Mode, rolled out to all sites on August 31, 2026, with impressions by page, country, device and date. Clicks from AI Overviews and AI Mode are also counted in the main Performance report under the Web search type.

Price: free.
Best for: everyone. It is the only first-party data on how Google's AI features show your pages.
Limitation: Google only, and the new report shows impressions rather than citations of your brand by name.

Bing Webmaster Tools AI Performance

Bing Webmaster Tools launched an AI Performance report in public preview in February 2026. It shows total citations, cited pages and a sample of grounding queries across Microsoft Copilot and Bing's AI summaries. A June 2026 update added intents, topics and citation share.

Price: free.
Best for: seeing which of your pages Copilot cites, from Microsoft's own data.
Limitation: it shows citations, not clicks or traffic, and the query data is sampled.

Bottally AI visibility and AI Overview checkers

The AI visibility checker puts your buyer questions to ChatGPT, Perplexity, Google AI Overviews and AI Mode and shows whether you are named or cited, and who is named instead. The AI Overview checker shows whether Google shows an AI Overview for a query and which sites it cites.

Price: free, no sign-up.
Best for: a quick baseline before you buy anything.
Limitation: each run is a snapshot. AI answers vary, so a trend needs weekly tracking, which is where the AEO trackers come in.

How to choose GEO tools

Fix access before you buy anything. A free audit and Search Console will show whether crawlers can reach and index your pages. No content tool helps a page that is blocked.
Buy for the job you will not do yourself. If writing is the bottleneck, pay for publishing. If your writers need structure, pay for a content editor. If you cannot tell whether AI crawlers visit, pay for log-based analytics.
Be skeptical of file and markup fixes sold as GEO. Google says llms.txt and special schema neither help nor harm in its AI features. Tools that lead with them are selling the easy part.
Check engines on your tier. Many tools track three engines on the entry plan and the rest on Enterprise. Our AEO tools comparison lists them tier by tier.
Confirm you have the data source. Crawler analytics need server or CDN logs. If your host does not expose them, that feature is wasted.
Start on monthly billing. Several vendors in this category changed their plans during 2026.

Do you need an llms.txt file?

llms.txt is a proposal by Jeremy Howard, first published in September 2024, for a markdown file at your site root that summarizes the site for AI agents. Google's guide says Google Search does not use it, and Semrush's testing found no link between having one and doing better in AI results. Chrome's experimental Lighthouse agentic browsing checks do look for one.

Our view: it takes minutes to add, so add one if you like, but do not expect it to change citations. Crawl access, indexing and content come first.

It can draft it. Google's guidance on generative AI content says to fact-check and review AI-written content before publishing, and its scaled content abuse policy applies to pages made mainly to manipulate rankings however they are produced. The tools above help with structure and coverage. Accuracy and a real point of view are still the writer's job.

Can I do GEO on my own?

Yes, and the free tools cover a lot of it. A starting plan for a beginner:

Run the free website audit and fix anything that blocks crawling or indexing.
Check robots.txt for rules that block OAI-SearchBot, PerplexityBot or Googlebot (the free audit flags the AI search crawlers). OpenAI says OAI-SearchBot is the crawler for ChatGPT search; GPTBot is for model training, and blocking it does not remove you from ChatGPT search.
Connect Google Search Console and Bing Webmaster Tools and look at the AI reports.
Run the AI visibility checker to find the buyer questions that go to competitors.
Publish one clear, specific page for each gap, with the answer in the first paragraph.
Re-check monthly and keep publishing.

Is SEO dead now with AI?

No. Google says GEO is still SEO, and its AI features run on its Search index. What has changed is the finish line: ranking is necessary, but you also want to be the source the answer quotes.

Start with what engines can see

Run the free website audit to confirm crawlers can reach your pages, then the AI visibility checker to see which questions engines answer without you. If publishing the missing answers is the job you want off your plate, Bottally Pro is $99 a month.
