technical SEO tools

Technical SEO tools crawl a site the way a search engine does and report what gets in the way of indexing: broken links, redirect chains, duplicate titles, missing canonicals, slow templates, orphan pages, and JavaScript that never renders. Some are desktop crawlers you run on demand. Others are cloud platforms that recrawl on a schedule, keep history, and alert you when a deploy breaks something.

Start with the size of the site. A few thousand URLs fit comfortably in a desktop crawler, and a free tier often covers the first audit. Above a few hundred thousand URLs you want cloud crawling, log file analysis, and change tracking, and the price jumps accordingly. Then check whether the tool renders JavaScript, because a crawler that only reads raw HTML will miss most of what a React or Next.js site shows to Google.

Look past the issue count. The useful tools explain why an issue matters, group it by template, and let you export a fix list a developer can act on. A crawler that reports 40,000 warnings with no prioritisation costs more time than it saves.

The grades on this page weight crawling, diagnostics, and measurement most heavily. Content generation and publishing carry almost no weight here, because that is not the job these tools do.
