Does the duplicate content on the crawl errors report test content on external websites?

[stuarta60]

Hello,

Can you tell me if this is just duplicate content within my site or if it also recognises duplicate content on external sites as well?

Thanks

I would slightly disagree with you on one point - the need to check every line. There are high probabilities, given the vastness of the web, of individual lines being found somewhere else. Where duplicate content becomes an issue is if a decent-sized section is found elsewhere or a large proportion of your page is not unique. So for an individual page, maybe checking half paragraphs wouldn't take too long, unless you have to do it site-wide.

It hadn't come across Copyscape, so that's helpful for me going forward. Thanks!

Yes, martin you're right, it is just an internal report. for external, you may want to use copyscape.com.

Copyscape will tell you whole no of websites with identical content as yours

Searching for duplicate content with Google search is very time consuming  as you would need to check each and every line

As far as I can tell it's just on your own site. To check externally copy a few sentences from the page you're testing, surround it in " " and paste it into a Google query. Repeat for a variety of sentences across the page.
