Detect content changes, broken links, meta tag modifications, and SEO-impacting edits the moment they happen — across your own site and competitor pages.
Manual audits happen too late. ChangeTower watches your pages 24/7 and alerts your team the instant anything changes that could affect your rankings.
Purpose-built capabilities that map to your exact workflow.
Track changes to title tags and meta descriptions across your site. Get alerted when a page's primary SEO signals are modified - intentionally or accidentally.
Monitor structured data (JSON-LD, microdata) for changes. Detect when FAQ, Product, or Organization schema is added, broken, or removed from your pages.
Watch canonical URLs for changes that cause duplicate content issues. Track redirect chains and detect when important pages start pointing to wrong destinations.
Monitor on-page content for changes that affect topical relevance. ChangeTower highlights word-level diffs so you can see exactly what was modified.
Side-by-side visual comparisons show layout changes that text diffs miss. Catch when a redesign accidentally hides important content from search engines.
Monitor technical SEO files for changes. Get alerted immediately when robots.txt blocks important pages or sitemap.xml drops critical URLs.
