Why this site only does SEO tools
Most "free online tools" sites try to be everything at once — a currency converter next to a QR generator next to a password strength checker, with an SEO section buried somewhere in the middle. IdiotTools SEO takes the opposite approach: this domain covers exactly one category, SEO tools, and every tool added here has to earn its place by solving a genuinely different problem an SEO practitioner, content writer, or site owner runs into. Nothing on this site is filler, and no two tools do the same job with a different name.
How the tools actually work
Every tool on this site runs entirely with client-side JavaScript, directly in your browser tab. When you paste text into the keyword density checker or upload a title into the meta tag generator, that data is processed on your own device and is never transmitted to a server, logged, or stored anywhere. This has a practical upside beyond privacy: there's no daily usage limit, no account to create, and no waiting on a server response, since the entire calculation happens the moment you click a button.
It also means these tools have an honest limitation worth being upfront about: anything that genuinely requires live external data — real-time search rankings, backlink discovery across the web, or a domain's current authority score — can't be done accurately by a page running only in your browser, since a browser can't freely query other websites' servers the way a dedicated crawler or paid API can. Rather than fake that kind of data with placeholder numbers, this site sticks to tools that can be done honestly and completely on the client side: content analysis, tag generation and auditing, technical file generation, and link/URL utilities.
Who this is for
The tools here are built for the everyday, repetitive parts of on-page and technical SEO work: checking a draft's keyword density before publishing, generating a clean robots.txt or sitemap for a new site, previewing how a title and description will actually look in search results, or auditing a page's existing meta tags for something obviously missing or duplicated. If you find yourself reaching for a spreadsheet formula or a half-remembered mental rule of thumb to do one of these tasks, there's a good chance there's a tool for it here.
