How to monitor website changes that affect SEO
You do not need to watch every pixel. You need a short list of URLs, a list of SEO signals, a schedule, and a place the evidence goes when something changes.

1. Pick URLs that represent templates
One homepage ping will miss a noindex that only shipped on the product template. Choose a URL for each template that can hurt revenue or trust: home, category, product, article, location, checkout-adjacent content, and the pages you just launched.
2. Watch signals, not just HTML
A generic diff says “the page changed.” For SEO you care whether indexability, canonical, robots.txt, title, schema or main content changed. That is the job of technical SEO monitoring.
3. Attach evidence and an owner
An alert without a before/after becomes a meeting. TechDash stores the change, severity and affected URL so the person who can revert the template sees the same facts as the SEO.
4. Verify the fix
Re-run the check after the deploy. Do not treat “we merged the PR” as proof. If Google’s view also matters, use URL Inspection after the local check is clean.
Questions
How many URLs should I start with?
Start with representative URLs for each important template, plus legal and launch pages. Add more once the noise level is comfortable.
How often should checks run?
Daily is enough for most pages. Use hourly or 15-minute checks on URLs in a launch, migration or incident.
