Compare two dated, owner-confirmed HTML source captures for the same page. See actual old/new technical fields; failed captures remain unknown. Runs locally without live fetching.
With analytics consent, Mapseen measures tool starts, completed local results and successful copies using fixed labels. Your inputs and results are excluded. Example mode remains until you edit a text, choice or factual field; review confirmations do not change it.
Paste source text only. Parsing and comparison happen locally. Scripts are not run; no page is fetched, uploaded, stored or monitored. Exclude private account/customer content.
Capture the exact same URL with a consistent source method and record the dates. Paste the earlier and later HTML to compare titles, descriptions, first H1, declared canonicals, HTML robots directives and distinct static link counts. An intentional difference is not automatically a regression.
No. You supply two dated HTML captures and confirm their provenance. There is no background job, fetch or stored history.
No. This tool compares supplied HTML directives only. The live response, other directives and Google's recorded indexing evidence need separate verification.
That can produce misleading differences. Use the same exact URL and capture method, with comparable responses, and confirm this before comparing.
