Free tools are great. Ongoing monitoring is what wins.
Every tool here gives you a real, useful answer in a few seconds. Use them as much as you want. They’re free.
The bigger problem they don't solve: SEO and AI visibility are moving targets. A site that scored 90/100 today can drop to 60/100 next month after a redesign, a content migration, or a new Google update. The work isn't a one-time check, it's a recurring loop.
CrawlTide turns that loop into a product: weekly crawls, AI Visibility tracking, prioritized fix lists, and one-click article publishing to WordPress / Webflow / Shopify. Same engine that powers these tools, across your whole site, every week.
