Most lists of free SEO tools are lists of paid tools with a free trial. This one is not. Everything below is usable indefinitely without a card, and where a free tier has a hard limit, the limit is stated in the entry.
They are ordered by how much they change what you can do, not by how impressive the AI is. The first four are the ones that matter most and three of them are not marketed as AI tools at all.
How this list was checked
Every tool was loaded on its live site in August 2026 and confirmed to be trading and still offering the free access described. Anything that 404d, timed out, resolved to a parked lander or had quietly moved behind a paywall was cut before publication.
Free here means usable without payment details. Trials, credits that expire and "free for 7 days" did not qualify, which removed about half the tools that normally appear on lists like this one.
Why Distribb is not on this list
Worth saying plainly rather than sneaking it in at number one: Distribb is a paid platform and it does not belong on a list of free tools. There is no free tier that does the actual job, so putting it first here would be dishonest and would waste your click.
The useful thing to say instead is what free tools cannot do, because that is the real boundary. Free tools tell you things. They diagnose, research and check. Not one of them writes and publishes an article into your CMS on a schedule, builds links, or does anything at all while you are not sitting in front of it.
So the honest split is this: use the fourteen below to work out what to do, which costs nothing and is genuinely enough for many small sites. Pay for something only when the constraint has become execution rather than knowledge. When you get there, Distribb is what we sell and it is a paid product. What paid execution actually buys is set out in our roundup of automated SEO software.
1. Google Search Console
Free forever, and more valuable than every paid tool on the market for your own site, because it is the only source of what Google actually recorded rather than what a third party estimated.
Queries, positions, impressions, indexing status and Core Web Vitals, all first-party. If you use one thing from this list, use this one. See Google Search Console.
Limit: your own verified properties only, 16 months of data.
2. Bing Webmaster Tools
Free, and it includes a keyword research tool with actual volume data that Google gives away to nobody. Worth setting up purely for that, even if Bing traffic is irrelevant to you.
Also surfaces crawl and index issues that Search Console misses. See Bing Webmaster Tools.
Limit: your own verified properties.
3. Ahrefs Free SEO Tools
The most generous free offering from a major paid vendor. Backlink checker, keyword generator, SERP checker, broken link checker and website authority checker, all usable without an account for light volume.
Data quality is the same as the paid product, just rationed. See Ahrefs free SEO tools.
Limit: capped queries per day, top results only.
4. Google Keyword Planner
Free with any Google Ads account, no spend required. Volume is bucketed into ranges rather than exact unless you are spending, which is annoying and still useful.
The forecast tool is better than most people realise for judging seasonality. Nothing else free covers this much of the keyword universe.
Limit: ranges rather than exact volumes without ad spend.
5. AlsoAsked
Maps the People Also Ask tree for any query, which is the fastest way to see the actual shape of a topic. Three searches a day free, which is enough to plan an article.
Better than a keyword tool for structuring a page, because it shows the questions in the order people ask them.
Limit: three free searches per day.
6. AnswerThePublic
Question and preposition clusters around a seed keyword. Older and cruder than AlsoAsked but wider, and the free tier still returns enough to be useful.
Good for finding the long tail that keyword tools price at zero volume and real people still search.
Limit: a few free searches per day.
7. Screaming Frog SEO Spider
The best technical crawler there is, free up to 500 URLs, which covers most small sites entirely. Broken links, redirect chains, duplicate titles, missing metadata, orphan pages.
Desktop software rather than a web app, and the interface is dense. Nothing free comes close on depth.
Limit: 500 URLs per crawl. Paid crawlers that go further are compared in our list of AI SEO audit tools.
8. PageSpeed Insights
Free, official, and the tool Google's own Core Web Vitals reporting is based on. Gives both lab data and real-world field data where enough traffic exists.
The recommendations are specific enough for a developer to act on directly. Ignore the score, read the diagnostics.
Limit: none worth mentioning.
9. ChatGPT
The most useful free AI tool for SEO work that is not an SEO tool. Clustering a keyword export by intent, drafting outlines, writing schema, turning a crawl into a prioritised list.
The free tier is enough for all of that. It knows nothing about your rankings and will invent statistics if you let it, so use it on data you supply.
Limit: usage caps on the best model.
10. Frase free checkers
Three free checkers aimed at AI search specifically: whether a page reads well to AI engines, whether your domain is cited by them, and whether AI agents can actually read your site.
Narrow, quick and genuinely useful now that a real share of research happens inside chat interfaces. No account gymnastics.
Limit: checker tools only, the main product is paid.
11. SEO.AI free tools
A large collection of no-login utilities covering keyword ideas, rank checking, cannibalisation and various generators. Quality varies by tool and several are better than they need to be.
The cannibalisation checker is the standout and solves a problem most free tools ignore. Treat the collection as a toolbox rather than a workflow.
Limit: no login, so no saved history.
12. Quattr free tools
Title tag, H1, meta description and URL generators driven by the target keyword. Small, fast and better than writing them from a blank page.
Output needs editing, as with every generator. Useful when you are fixing metadata across a lot of pages. At real scale that becomes a different job, covered in our guide to programmatic SEO tools.
Limit: generation only, no analysis.
13. WordLift free tools
Schema and entity focused, which is the corner of technical SEO with the fewest free options. Product description generation, anchor text suggestions and markup validation. Anchor text at scale is its own problem, explained in our piece on how an AI internal linking tool works.
Narrow and well made. Worth knowing about specifically for structured data work.
Limit: individual tools, not a platform.
14. Microsoft Clarity
Free heatmaps and session recordings with no traffic cap, which is unusual enough to be worth stating twice. Not an SEO tool, and the fastest way to find out why a page that ranks does not convert.
Rage clicks and dead clicks are the two reports to open first. Free permanently, not a trial.
Limit: none on volume.
What a free stack actually covers
| Job | Free tool that does it | Good enough alone? |
|---|---|---|
| See your real rankings | Search Console | Yes |
| Find keywords | Keyword Planner, Bing, AlsoAsked | Yes for most sites |
| Technical audit | Screaming Frog, PageSpeed | Yes under 500 pages |
| Check backlinks | Ahrefs free checker | Partly, capped |
| Write and optimise | ChatGPT, Quattr | Partly, needs judgement |
| Track competitors | Nothing free does this well | No |
| Publish on a schedule | Nothing free does this | No |
| Build links | Nothing free does this | No |
The bottom three rows are the honest boundary of a free stack, and they are the reason paid tools exist. Everything above them is genuinely solved for free. Coordinating the work itself is another gap, and we compared SEO project management tools for it.
The trap in free tools
The cost of a free stack is not money, it is your time and the switching between six interfaces that do not talk to each other. For a site under a hundred pages that is fine and the maths favours free. If you are weighing paid options, our guide to Outrank alternatives covers the automated end.
Past that, the tool sprawl starts costing more in hours than a subscription would. Our comparison of affordable SEO tools covers the tier just above free, AI-driven SEO tools covers the paid AI end, and SEO audit tools goes deeper on the diagnostic side.
Where to start
Set up Search Console and Bing Webmaster Tools today, run Screaming Frog against your site, and fix what both of them are already telling you. That is a free afternoon and it beats buying anything.
Come back to paid tools when you know what to do and cannot get it done. That is the point where Distribb is worth looking at, and not before. Our practical comparison of the best automated SEO tool weighs the options at that point.
