Catch SEO-Breaking Changes Before Rankings Drop
A redesign drops your H1. A CMS edit rewrites a title tag. A plugin adds noindex. Site Monitor watches your money pages and alerts you when anything that affects rankings changes — or when a competitor rewrites theirs.

How it works
Add your top pages
The pages that drive the most organic traffic, plus a few competitor pages you're trying to outrank.
Turn on change + link checks
Content change detection catches heading and copy edits; broken-link crawling catches dead internal links.
Fix regressions fast
The AI summary in your dashboard describes what changed so you can roll it back before it affects rankings.
You choose which alerts each URL sends — downtime, content changes, slow responses — and we email you when they happen.
What you can track
- Heading and on-page copy changes on top-ranking pages
- Broken internal links
- Pages going down or returning errors
- Slow response times on key landing pages
- Competitor page rewrites on keywords you target
Search Console finds problems too late
Ranking and coverage reports lag by days. By the time a traffic drop shows up, the change that caused it may be weeks old and hard to trace.
Monitoring the pages themselves gives you a dated change log you can line up against traffic graphs.
Frequently asked questions
Will rotating ads, timestamps, or counters cause false alerts?
Not if you scope the watch. Add a CSS selector (for example #pricing or .event-list) and Site Monitor fingerprints only that element — everything else on the page is ignored. Whitespace-only changes never trigger an alert.
Can it find broken links?
Yes. Turn on sub-link crawling for a URL and Site Monitor checks the links on that page and reports any that break.
What is an AI change summary?
When a page changes significantly, Site Monitor uses AI to describe in plain English what was added, removed, or reworded. Summaries appear in the site's dashboard — your email alert links straight there. The Free plan includes 2 AI summaries a month; paid plans include more.
How often does Site Monitor check a page?
Free checks every hour. Paid plans check as often as every 5 minutes, and you can set the interval per URL.
Is Site Monitor free?
Yes. The Free plan covers 10 URLs checked every hour, with 2 AI change summaries a month — no credit card required. Upgrade only if you need faster checks, more URLs, or more AI summaries.
Does it work on pages that load content with JavaScript?
Yes. Site Monitor can render the page in a headless browser before fingerprinting it, so content injected by JavaScript is included in the comparison.
