If you do not believe Google’s Duplicate Content Filter exists, I’ve got Dramatic Proof their Net content filter exists and it’s terribly effective.

On July five, 2005 I printed a commentary entitled “seven High Ways in which to Avoid Link Theft” which was picked up and included as content on alternative websites.

Before the article was released I checked on Google whether or not any results already existed for the precise phrase “7 Prime Ways in which to Avoid Link Theft” and there were no listings for that term.

Over the following few weeks I monitored through a research question on Google how many results appeared in Google for the title of my article. One week once publication there were vi,760 results listed in Google, every week later it had been fourteen,one hundred and it reached a peak of seventeen,000 results by July twenty six, 2005.

4 weeks after publication the results in Google had fallen slightly to 16,600.

Almost half-dozen weeks once publication the results listed in Google had fallen to 44.

In an exceedingly matter of less than 2 weeks the quantity of search results on Google.com for the title of my article had gone from 16,600 to only 44.

In case you’re thinking this is often because of these different websites dropped by article and replaced it with different content I ought to add {that a} search on Yahoo.com on the identical day still showed 14,three hundred results for my article.

What is a lot of of these 44 results on Google, additional than half include listings from the identical websites. In other words some sites have the identical article duplicated on different pages on their website.

Thus Google’s Net Content Filter is not used to get rid of duplicate listings from the popular websites it chooses to stay in the search results.

On August twenty eighth, 2005 8 weeks after first publication I distributed the article once more to a brand new list of article sites to repeat the process. After half-dozen weeks the same article had reached a peak of five,620 results on Google. But 2 weeks later the results had fallen to 217.

On behalf of me this was dramatic proof that Google’s Duplicate Net Content Filter is active and terribly effective. If you are wondering if alternative major search engines have a replica content filter I can make sure that Yahoo definitely does. The identical article that was once listed on 14,three hundred sites on Yahoo, has fallen to 344 over the identical time period.

From these results it would seem Google takes concerning half-dozen to 8 weeks to get rid of duplicate content using its Duplicate Internet Content Filter.

However the question remaining is simply how will Google decide that out of over 16,000 results will it keep and which will it reject?

I’ve got witnessed situations where my own articles seem in results on other websites, however don’t seem to be listed in the results for my very own website.

Thus clearly Google will not take into account who the originator and author of the original article was when deciding which sites can stay in its search results.

It additionally seems to have nothing to try to to with where Google 1st finds the article.

Some articles I have published to my web site for many weeks before releasing them for distribution to different websites.

In that point the Google spiders have visited my web site several times and Google has had enough time to work out {that the} article was initial found on my site.

It might be fascinating to see if it’s doable to figure out what factors Google is using in its Internet Content Filter to make a decision that results to keep in its listing and which ones to remove. However that’s for an additional article.
