What Is Actually Free Here
Most “free SEO tools” pages promise a wall of widgets and deliver a wall of signup forms. Here is the honest inventory instead. AEO Goal has exactly one interactive tool that runs free with no signup: the AI visibility scan on the homepage. Everything else in this toolbox is one of three things, each labeled below: a working guide with copy-ready output you can use today, a calculation model you run with your own data, or documentation of an in-app feature that requires an account. Knowing which is which before you click is the point of this page.
Start With The Scan
Enter any domain on the homepage and the scan live-fetches the homepage, robots.txt, and llms.txt, checks robots.txt access for 16 AI crawler user agents, parses JSON-LD, and verifies canonicals, H1 structure, titles, metadata, and entity salience. It returns a 0 to 100 AEO readiness score with a ranked issue list. It is a zero-LLM, single-page scan, but because robots.txt and llms.txt are sitewide files, its access findings apply to your whole domain. It also accepts competitor domains, which makes it the fastest free head-to-head available.
Run it first because it tells you which guide below you actually need.
Guides With Copy-Ready Output
These pages contain the deliverable itself, no account required:
- Robots.txt generator: the documented behavior of GPTBot, OAI-SearchBot, Google-Extended, ClaudeBot, PerplexityBot, and Bingbot, plus least-privilege robots.txt patterns to copy, including the train-versus-retrieval opt-out split.
- Schema markup generator: copy-ready JSON-LD for Organization, Article, and FAQPage, with the eligibility caveats that changed what FAQ markup is worth.
- Content optimizer: the answer-first, entity clarity, and extractability method for making existing pages quotable, with decision rules for optimize versus rewrite versus consolidate.
- Technical SEO audit: the four gates a page must pass, how to prioritize findings by root cause, and what the free scan covers versus a site-wide crawl.
Models You Run With Your Own Numbers
Two pages walk through calculations step by step, using your Search Console and analytics data rather than invented benchmarks:
- Organic traffic calculator: impressions times CTR at target position, minus current clicks, with an explicit AI answer haircut and instructions for building CTR curves from your own queries.
- SEO ROI calculator: the full ROI formula with every input sourced, a worked example with labeled assumptions, and the three-scenario discipline of funding only what survives the conservative case.
Guides To The In-App Tools
These pages explain how each in-app tool works and how to interpret its output, so you know what you are getting before you create an account. The tools themselves sit behind signup or a free trial, and the pages say so:
- Keyword research tool: reading volume, difficulty, intent, and AI answer frequency, and mapping keywords and prompts to one canonical page each.
- Keyword competitor tracker: the three signals to track per topic, your ranking, brand mentions in AI answers, and cited URLs, and how to read a head-to-head.
- Competitor SEO analysis: comparing brands across classic rankings and AI citations, including the free scan-versus-scan comparison you can run today and the Share of Model tracking that requires the app.
- Backlink checker: what referring domains, domain rating, and anchors actually measure, and how link authority feeds citation decisions indirectly.
- AI blog generator: what the research-first generator produces, how the AEO Quality Score works, and the human review gate every draft passes through.
For learning rather than doing, the free AEO and SEO course and the technical SEO checklist are both free and signup-free.
The Boundary, Stated Once
Free gets you diagnosis: the scan finds what is broken, the guides show you how to fix it by hand, and the calculators tell you what the work is worth. The paid product is the loop that free tools cannot close: continuous AI citation tracking across ChatGPT, Claude, Gemini, and Perplexity, Share of Model against named competitors, scheduled re-crawls and re-audits, and an agent that turns every detected gap into a concrete fix and re-checks it. If you are comparing platforms for that job, best AI SEO tools and pricing are the two pages to read. Free tools find the gap; the product exists to close it and prove it closed.
