How to use it
  1. Enter the complete public URL and load its timeline.
  2. Select the baseline capture.
  3. Choose current, previous, next, or another capture as the comparison target.
  4. Review field-level changes and the extracted-text diff, then open the source capture when context matters.

Example result
A comparison might show that the selected archive capture used one canonical URLHow search engines pick one canonical URL among duplicates and consolidate signals onto it. while the current raw HTML uses another, alongside the exact title, robots, heading, and extracted-text changes. Each difference is evidence to investigate, not an automatic SEO defect.
How it works
The tool loads a bounded capture timeline, fetches the two selected raw-HTML sources through the site API, extracts the same observable fields from each, and computes a capped text diff. It does not execute archived JavaScript or replay subresources.
What is compared
HTTP status where available, title, meta description, canonical, robots directivesThe robots meta tag is an HTML element in a page's head — <meta name="robots" content="noindex"> — that tells search engines how to index and serve that page. It's crawl-then-obey: a page blocked in robots.txt is never fetched, so the tag is never seen., H1s and heading outline, hreflang declarationsHreflang is an annotation (in HTML, HTTP headers, or XML sitemaps) that tells search engines which language and optional region a page targets, and which alternate versions exist. It only works when every page in the cluster references all the others., JSON-LDJSON-LD (JavaScript Object Notation for Linked Data) is a script-based structured data format, typically paired with the schema.org vocabulary to describe page content for search engines and AI systems. Google recommends it over Microdata and RDFa because it's the easiest format to implement and maintain at scale — but all three work, and structured data isn't a ranking signal. type evidence, extracted word count, links, images, and images missing an alt attribute. Every value comes from bounded raw HTML; a difference is a review prompt rather than an automatic defect.
Limitations
Archived captures can be incomplete or replay incorrectly. Current and archived fetches can occur at different times. Text extraction includes templates and navigation, schema counts include malformed JSON-LD blocks, and truncated HTML can undercount facts. No scripts execute and no archived subresources load.
Frequently asked questions
What can I compare?
Choose one archived capture, then compare it with the current live raw HTML, the previous capture, the next capture, or any other capture in the returned timeline.
Does this reproduce an old rendered page?
No. It compares bounded raw-HTML facts and extracted text. It does not run archived scripts or load archived styles, images, fonts, or other subresources.
Does a missing capture prove the page did not exist?
No. Archive coverage can be incomplete, excluded, or unavailable. A missing capture is only absence from the returned timeline.
Is this affiliated with the Internet Archive?
No. The tool uses the Wayback Machine and links to the Internet Archive donation page, but this site is not affiliated.
