Your resource may not be included in search results.

How search engines define similarity of texts?
There is Shingles algorithm, allowing simple duplicate content check to be convinced that between them exists a similarity.

Splitting of texts into words, and then comparison of the received matrix. So to become not important if you have simply rearranged words or offers (if division goes on 1 word). Text Splitting can be both by one word, and on some, ie shingle from several words.

This service make possible to check content for uniqueness after document changes.
