How to choose site audit and technical seo tools
A site audit tool crawls your pages the way a search engine does and lists what gets in the way: broken links, redirect chains, duplicate titles, missing canonicals, blocked resources, slow templates. The tools split two ways, desktop crawlers you run yourself and cloud crawlers that audit on a schedule, and the right one depends on whether you need a deep look once or a watchful eye every week.
Start with the free sources
Google Search Console and Bing Webmaster Tools report what the search engines themselves found: pages excluded from the index and why, Core Web Vitals from real visitors, and crawl errors. No third-party crawler can tell you that. Run them first, then use a crawler to find the cause.
Desktop crawlers
Screaming Frog SEO Spider is free up to 500 URLs, and its paid licence is $279 per user a year with no crawl limit beyond your computer's memory. Sitebulb starts at $180 a year for 10,000 URLs per audit, and its Pro desktop plan covers 500,000 for $425 a year. Desktop crawlers are cheap for what they do and suit one-off deep audits, migrations and sites with odd configurations you need to tune for.
Cloud crawlers
Cloud tools run on a schedule and alert when something changes, which matters more on large or busy sites than a single deep crawl. Most SEO suites include one. Seobility has a free plan with 100 pages per crawl, and SE Ranking includes audits in its core plan. Enterprise crawlers such as Botify, Oncrawl and JetOctopus add log-file analysis, which shows what Googlebot actually crawls rather than what a crawler can reach.
How to choose
- Page count. Match the plan's crawl limit to the number of URLs your site really exposes, including parameters and pagination, not the number of pages in your CMS.
- JavaScript rendering. If your content is built in the browser, the crawler must render it, or it will audit an empty shell.
- Prioritisation. A list of 4,000 warnings is useless. Look for tools that rank issues by how many important pages they affect.
- Monitoring. For a site that changes often, scheduled crawls with alerts catch a broken template the day it ships.
