Duplicate content across two websites

[Blink-SEO]

Hi. I'm looking at ways to compare duplicate content across two different websites instead of one, as with the Moz crawler. Instead it will flag up up duplicates present on both site A and B.

You can use Copyscape. You can also take a small piece of the copy and wrap in quotes and enter it into Google search. I would do the latter, before the former. Copyscape costs $.05 per page.
