Most lists of “free AI SEO tools” pad themselves with paid tools that have a 7-day trial. That’s not free. This is a curated list of 12 AI SEO tools that are actually free, with no credit card or trial-conversion gimmicks (the free tiers are real, even if they have usage limits).

I’ll cover what each one does, who it’s best for, and where the free tier hits a wall, so you can match the tool to the job. There’s also a workflow at the bottom for stitching them together into a complete free SEO stack.

How I picked these tools

  • Genuinely free. Either free forever, or a meaningful free tier (not a 7-day trial that turns into a paid plan).
  • SEO-specific. General AI chatbots are included only when there’s a clear, specific SEO use case.
  • 2026-relevant. Includes the newer GEO and AI-citation category alongside the classic keyword/audit tools.
  • Tested by real practitioners. Tools that working SEOs recommend across the SERP, Reddit threads, and SEO YouTube.

1. Google Search Console

Google Search Console is the non-negotiable free tool. It’s Google’s own data on how your site performs in search: clicks, impressions, average position, top queries, indexing status, and Core Web Vitals. Since August 2026 it also has a Generative AI performance report that shows how often your pages appeared in AI Overviews and AI Mode (impressions, not clicks). To ask questions about that data in plain language, you can connect Search Console to Claude through an MCP server.

Best for: any site that wants to understand its real search performance, including how often Google’s AI features show your pages.

Free tier limits: none. Free forever. The only requirement is verifying ownership of your domain.

2. Ahrefs Free (Ahrefs Webmaster Tools)

Ahrefs Webmaster Tools (AWT), now renamed Ahrefs Free, is the free version of Ahrefs scoped to your own verified sites. You get a real site audit, the backlinks pointing to your site, and the keywords you rank for, with no credit card. Ahrefs also has a free AI visibility checker that shows how ChatGPT, Gemini, Perplexity, Copilot, and Google’s AI Overviews and AI Mode talk about any brand, with no signup.

Best for: site owners who want pro-level SEO data on their own site without paying $129/month for Ahrefs Lite.

Free tier limits: only your verified properties (no competitor research). Site Audit gets 5,000 crawl credits per project each month and Site Explorer shows up to 1,000 backlinks and keywords at a time, but the data is real Ahrefs data.

3. Bing Webmaster Tools

Bing Webmaster Tools is criminally underrated. The free Keyword Research tool inside it has fewer caps than Semrush’s free plan, and since February 2026 its AI Performance report shows how often Microsoft Copilot and Bing’s AI summaries cite your pages. Google’s new report counts impressions; Bing’s shows which of your pages get cited, which is useful input for generative engine optimization.

Best for: keyword research on a budget, plus visibility into how often Copilot and Bing’s AI answers cite your content.

Free tier limits: none. 100% free, no credit card.

4. AIOSEO Analyzer

AIOSEO Analyzer runs a full on-page audit on any URL for free. Your first check needs only the URL; after that, it asks for your name and email. It scores titles, meta descriptions, headings, image alt text, internal links, schema, and basic technical issues. Results in under 10 seconds.

Best for: a quick “is this page well-optimized” check on any URL, including competitor pages.

Free tier limits: single-URL audits only. No bulk audits or saved history. Their paid plugin (AIOSEO Pro) handles those.

5. seo.ai’s free tools

seo.ai’s tool collection is a utility belt: more than 40 small, focused tools for everything from SERP simulation to article rewriting to keyword density checks. No login required for most of them.

Best for: one-off SEO tasks where you don’t want to install or sign up for anything. Useful for content audits and quick optimizations.

Free tier limits: the deeper AI features (full article generation) require a paid seo.ai plan. The utilities themselves are free.

6. Ubersuggest

Ubersuggest, Neil Patel’s tool, gives you keyword volume, SEO difficulty, top-ranking pages, and basic competitor analysis. The free tier is capped, but the data quality is solid for the price.

Best for: quick keyword checks and competitor URL audits without paying for a full SEO suite.

Free tier limits: three searches per day on the free plan. Beyond that you’ll be prompted to upgrade.

7. Semrush free account

Semrush offers a free account (no credit card) that gives you 10 reports per day across its main tools, including keyword research and competitor research. Industry-standard data inside strict caps. Semrush also has a free AI Search Visibility Checker you can run three times a day without an account.

Best for: SEO professionals who want to spot-check Semrush data without committing to the $139/month SEO plan.

Free tier limits: 10 reports per day and one project. Bigger site audits, more tracked keywords, and AI prompt tracking need a paid plan.

8. RightBlogger free tools

The Keyword Research tool: a RightBlogger on-page SEO AI tool

RightBlogger has a set of standalone free SEO tools you can run in your browser without signing up (a free account keeps them going after a few runs): a meta title generator, meta description generator, Google SERP preview, People Also Ask tool, and a permalink generator. There’s also a free AI Visibility Checker that shows whether ChatGPT and Perplexity name your site for questions in your niche, and which sources they cite instead. The keyword research and content gap tools need a free account. Disclosure: this is our tool, so weigh accordingly.

Best for: bloggers who want a single set of free utilities for the day-to-day on-page SEO work that GSC and AWT don’t cover.

Free tier limits: a free account gets 2,000 AI words a month and limited keyword research, and the AI Visibility Checker allows a few checks a day. Unlimited writing, SEO reports, the Site Agent, and ongoing autoblogging need a paid plan (from $49/month billed annually).

9. ChatGPT (free tier)

ChatGPT’s free tier is genuinely useful for SEO work, even if it isn’t an “SEO tool” in the traditional sense. The specific use cases that work well: drafting article briefs, generating outlines from a target keyword, writing schema markup, suggesting internal links from a sitemap paste, and rewriting meta descriptions in bulk.

Best for: the planning and drafting layer of SEO work. Not a substitute for keyword data tools, but a strong complement.

Free tier limits: everyday chats are unlimited on a lighter model, and web search is included. OpenAI’s newest models are paid-only, and file uploads, image creation, and deep research are capped.

10. Frase GEO Score Checker

Frase’s GEO Score Checker is a free standalone tool that checks how ready a page is to be cited in AI search on engines like ChatGPT, Perplexity, and Claude, and points to what to improve.

Best for: auditing your existing content for AI-citation readiness, which is increasingly distinct from traditional Google ranking.

Free tier limits: the standalone tool is free. Frase’s full editor and content optimization platform is paid.

11. Otterly.AI free tools

Otterly.AI publishes a set of free GEO tools, including a query fan-out generator and an AI crawler simulator. Its AI search tracking platform is paid, with a 7-day free trial.

Best for: SEOs who want to see the follow-up searches AI engines run for a topic and how AI crawlers see their pages, without paying for a tracking platform.

Free tier limits: the standalone utilities are free. The tracker has no free plan; after the trial, it starts at $29/month.

12. LLMrefs

LLMrefs is one of the newer entries in the LLM brand visibility category, and you can start with a free account. It tracks how often a brand or domain shows up in answers from ChatGPT, Perplexity, Gemini, and other AI engines.

Best for: tracking your own (or a competitor’s) brand mentions across LLM answers as part of a GEO strategy.

Free tier limits: LLMrefs doesn’t publish the free account’s limits, and meaningful tracking volume is on the paid plan.

A free SEO workflow stitching these together

Twelve tools is a lot. In practice, the strongest free stacks combine them in six steps.

  1. Foundation: Google Search Console + Ahrefs Webmaster Tools + Bing Webmaster Tools. Set these up once for any site you own. They’re the data layer everything else builds on.
  2. Keyword research: rotate between Bing Webmaster Tools (no caps), Ubersuggest (3/day), and Semrush free (10/day) to triangulate volume and difficulty without hitting any single cap.
  3. Content briefs: ChatGPT free tier for outlines and structure. Paste in your top-ranking competitors and ask it to identify subtopics they cover that you don’t.
  4. On-page audit: AIOSEO Analyzer for the page itself, AWT for site-wide issues, seo.ai’s tools for one-off micro-checks.
  5. GEO check: Frase GEO Score Checker on the published URL, plus Otterly.AI’s free query fan-out tool to see the related searches AI engines run for your topic.
  6. Monitor: GSC (including its Generative AI report) for Google, Bing’s AI Performance report for Copilot citations, LLMrefs for ChatGPT and other engines, and AWT for backlink growth.

Free AI SEO tools FAQ

Are there any AI SEO tools that are actually free, not just a trial?

Yes. Google Search Console, Ahrefs Free (formerly Ahrefs Webmaster Tools), Bing Webmaster Tools, AIOSEO Analyzer, and seo.ai’s utilities are all free forever (or free for verified site owners). The rest of the list above has meaningful free tiers that stay usable well past the first week.

Can I do SEO without paying for any tools?

Yes, especially for a single site. The combination of GSC + AWT + Bing WMT + ChatGPT free tier covers most of what bloggers and small business owners need. You’d only outgrow the free stack when you need to track competitors at scale or run bulk technical audits.

What’s the best free tool for tracking AI Overviews and ChatGPT citations?

For Google, use Search Console’s Generative AI performance report, which counts your impressions in AI Overviews and AI Mode. For Microsoft Copilot, use the AI Performance report in Bing Webmaster Tools. For ChatGPT and the rest, spot-check with a free AI visibility checker from Semrush, Ahrefs, or RightBlogger, then add a tracker like LLMrefs if you need ongoing numbers. None of them is complete on its own; together they cover the major AI-search surfaces.

Is ChatGPT good for SEO?

For specific tasks, yes: drafting briefs, writing schema markup, generating outlines, rewriting meta descriptions. For keyword data, no. ChatGPT doesn’t have real search volume or competition data. Pair it with a tool that does (Bing WMT, Ubersuggest, Semrush free).

Does Google have a free AI SEO tool?

Google Search Console is the closest. Its Generative AI performance report shows how often your pages appear in AI Overviews and AI Mode, alongside the usual query-level CTR and indexing data. It’s the most actionable AI-related SEO data Google publishes.

Picking your free SEO stack

You don’t need 12 tools to do free SEO well. Pick the foundation (GSC + AWT + Bing WMT) and add 1-2 specialty tools for the workflow gaps you actually hit. The biggest mistake on a free stack is using too many overlapping tools instead of using a few well.

If GEO and AI search visibility matter for your niche, prioritize the free AI-search tools (the AI reports in Search Console and Bing, Frase GEO Score, Otterly.AI’s utilities, and a free AI visibility checker) over yet another keyword tool. The category is moving fast, and the free tools are the leading edge.
