What are free SEO tools?
Free SEO tools are no-cost utilities that check or generate one search-optimization element at a time, such as a title tag, a robots.txt file or a sitemap. They fix on-page and technical basics fast. They do not replace keyword data, rank tracking or a content plan.
That limit is worth knowing before you rely on them. A title checker can tell you a title is too long. It cannot tell you whether anyone searches for the phrase in it. Use these tools to get the mechanics right, then use research to decide what to write.
How to use these free SEO tools together
Run them in the order a page is built. The sequence below takes a new page from draft to crawlable in about twenty minutes.
Write the snippet
Draft the title and description with the SEO title checker and the meta description checker. Fix anything cut off or missing the keyword.
Clean the URL
Run the headline through the slug generator to get a short, readable path.
Review the copy
Paste the draft into the keyword density checker to catch repeated phrases, and confirm length with the word counter.
Open the doors to crawlers
Generate a robots.txt and a sitemap, then test access with the AI crawlability checker.
Add structured data, then measure
Mark up Q&A content with the FAQ schema generator. After you publish, watch impressions and clicks in Google Search Console, which is also free.
Free SEO tools for AI search and GEO
Generative engine optimization (GEO) is the work of getting your pages found, understood and quoted in AI-written answers, in addition to ranking in classic search results. It starts with the same basics as SEO, plus a few checks that only matter to AI crawlers.
Let the right crawlers in
A page cannot be cited if the crawler behind the answer engine is blocked. Use the AI crawlability checker to confirm that search crawlers such as OAI-SearchBot, Claude-SearchBot and PerplexityBot are allowed, then decide separately whether to allow training crawlers.
Write answers that can be quoted
AI answers often break one question into several smaller searches. Pages that answer each sub-question directly, with the answer in the first sentence under a clear heading, are easier to lift and cite.
Keep llms.txt in proportion
An llms.txt file costs minutes to make and may help some tools find your best pages. No major provider has promised to use it, so do it after crawl access and answer-first content, not before.
Free SEO tools vs. a platform that runs SEO for you
Free tools are the right call for a one-off fix. They stop short of the recurring work that actually moves rankings.

Free SEO tools: your questions answered
What are the best free SEO tools?
The best free SEO tools depend on the job. For on-page basics, use a title and meta checker, a slug generator and a keyword density checker. For technical SEO, use a robots.txt generator, a sitemap generator and Google Search Console. For AI search, use an AI crawlability checker to confirm answer engines can reach your pages.
Are free SEO tools accurate?
They are accurate for what they measure, such as character counts, rule parsing and file formatting. They are less reliable at anything that needs live data. Pixel-width previews are estimates, and Google can rewrite titles and descriptions regardless of what you set.
Do I need to sign up to use these free SEO tools?
No. Every tool in this directory works without an account.
What is a good SEO title length?
Aim for roughly 50 to 60 characters. Google truncates titles by pixel width, around 600 pixels on desktop, so wide letters like W and M use up space faster than narrow ones. Put the main keyword near the start so it survives any cut-off.
How long should a meta description be?
Keep it between about 120 and 160 characters, with the main point in the first line. Meta descriptions do not directly affect rankings, but they influence whether people click, and Google often replaces them with text pulled from the page.
Is there an ideal keyword density?
No. Google does not publish a target keyword density, and chasing a percentage tends to produce awkward copy. Use a keyword density checker to spot unnatural repetition, and make sure the page covers the topic and its related terms.
What does a robots.txt file do?
A robots.txt file tells compliant crawlers which parts of your site they may fetch. It controls crawling, not indexing, so a blocked URL can still appear in search results if other pages link to it. To keep a page out of search, use a noindex directive instead.
Should I block AI crawlers in robots.txt?
It depends on what you want. Blocking training crawlers such as GPTBot or ClaudeBot keeps your content out of model training. Blocking search crawlers such as OAI-SearchBot or PerplexityBot can stop your pages being cited in AI answers. Many sites block the first group and allow the second.
What is llms.txt and do I need one?
Llms.txt is a proposed plain-text Markdown file at your site root that summarizes your site and links to key pages for language models. You do not need one. AI providers have not committed to reading it, so it is a low-cost extra rather than a requirement.
What is GEO and how is it different from SEO?
GEO, or generative engine optimization, is optimizing content to be cited in AI-generated answers from tools like ChatGPT, Perplexity and Google's AI features. SEO aims for rankings in a list of links. GEO aims for a mention inside the answer. They share most fundamentals, including crawlable pages, clear structure and genuinely useful content.
Can I do SEO with only free tools?
Yes, for a small site, with limits. Free tools plus Google Search Console cover technical checks and basic measurement. The harder parts are keyword research, consistent publishing and tracking results over months, which take time or a paid platform to do well.
Free tools fix the basics. PilotDeck runs the rest.
