Website change detection for SEO: see what changed since the last crawl
SEOSage is a desktop app for Mac and Windows. After each full crawl, SEOSage saves a small summary of every page on your computer. The next time you crawl the same site, it lists what changed, one entry for each change.

What changed since the last crawl? Crawl the site again, and SEOSage lists every change on every page. Each one shows what the page had before, and what it has now. It all stays on your computer. Start your fourteen-day free trial at seosage.co.
See what changed on each page
Crawl a site once, then crawl it again. Changes appear in the Issues list under the category Changes. Each one says what the page had before and what it has now. A simple way to monitor SEO changes after a site update: crawl again and see which pages lost a title, picked up a noindex or now redirect somewhere else.
/pricing/The title changed since the last crawl. Before: "Pricing". Now: "Pricing and plans".
/blog/site-audit/The page had 640 words in the last crawl and has 280 now.
/services/This page could be indexed in the last crawl and is now set to noindex. Check that this is on purpose.
What it looks for
- Title tag changed: The page title is not the same as in the last crawl
- H1 tag changed: The main heading is not the same
- Meta description changed: The description is not the same
- Word count changed: A change of at least 20 percent and at least 50 words
- Canonical URL changed: The canonical address points somewhere else
- Noindex page became indexable: A page that was set to noindex can now be indexed
- Indexable page became non-indexable: A page that could be indexed is now set to noindex
- Redirect target changed: An address that redirected to one page now redirects to another
Good to know
The summary of each page is saved on your computer after every full crawl, and nothing is sent anywhere. The first crawl of a site has nothing to compare with, so changes show from the second crawl on. It works on sites on your own computer too.
A crawl that you stop saves no summary, so it is not used as the starting point for the next comparison. Pages with parameters in the address are left out. This is separate from Compare, which compares the issue counts of two crawls.
How it works in three steps

Questions about this check
What is change tracking?
After each full crawl, SEOSage saves a small summary of every page on your computer. On the next crawl of the same site, it compares each page with that summary and lists what changed.
Which changes does it find?
Title tag changed, H1 tag changed, Meta description changed, Word count changed, Canonical URL changed, Noindex page became indexable, Indexable page became non-indexable and Redirect target changed. They show in the Issues list under the category Changes. Pages with parameters in the address are left out.
Why does my first crawl show no changes?
The first crawl of a site has nothing to compare with. Changes show from the next crawl of the same site. A crawl that you stop saves no summary, so it is not used for the next comparison.
How big does a word count change have to be?
The page must change by at least 20 percent and by at least 50 words. Smaller edits are not listed.
Is my data sent anywhere?
No. The summary is kept on your computer and is not sent anywhere. Change tracking also works on sites that run on your own computer.
How is it different from Compare?
Compare looks at the issue counts of two crawls. Change tracking looks at the pages themselves and lists each page whose title, heading, description, canonical address, indexing, word count or redirect changed.
