If you don’t believe Google’s Duplicate Content Filter exists, I have Dramatic Proof their Internet content filter exists and it’s very effective.
On July 5, 2005 I published an article entitled “7 Top Ways to Avoid Link Theft” which was picked up and included as content on other websites.
Before the article was released I checked on Google whether any results already existed for the exact phrase “7 Top Ways to Avoid Link Theft” and there were no listings for that term.
Over the next few weeks I monitored through a search query on Google how many results appeared in Google for the title of my article. One week after publication there were 6,760 results listed in Google, a week later it was 14,100 and it reached a peak of 17,000 results by July 26, 2005.
4 weeks after publication the results in Google had fallen slightly to 16,600.
Almost 6 weeks after publication the results listed in Google had fallen to 44.
In a matter of less than two weeks the number of search results on Google.com for the title of my article had gone from 16,600 to just 44.
In case you’re thinking this...
