About this tool
Compare two pages and see how similar their main text is, whether titles and descriptions match, and how their canonical tags handle it.
Navigation, header, footer, forms and scripts are removed, and the remaining text is split into overlapping five-word sequences (shingles). Similarity is the share of sequences both pages have in common (Jaccard index); containment shows how much of the shorter page is inside the longer one.
Example: check First page = https://example.com/, Second page = https://example.org/.
Similar text is normal for product variants or translated pages; canonical and hreflang tags tell search engines how to treat them.
Quick steps
- Enter the address of a public page or domain.
- Press Check. The 1CLIK server visits it, which can take a few seconds.
- Read each line — Good, Improve, Problem or Info — with a hint on what to fix.
1CLIK’s server fetches only the public address you enter. Private and internal addresses are refused, and results are cached for a few minutes, not saved to your account.

What should I keep in mind?
Similar text is normal for product variants or translated pages; canonical and hreflang tags tell search engines how to treat them.
Why can the result differ from what I see in my browser?
The check sees what the server sends to 1CLIK, before any JavaScript runs. Sites can also answer automated requests differently, block them, or vary by country.
