Google’s Duplicate Internet Content Filter In Action
If you don’t believe Google’s Duplicate Content Filter exists, I have Dramatic Proof their Web content filter exists and it’s very effective.
On July 5, 2005 I printed a piece of writing entitled “seven Top Ways in which 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 precise phrase “7 High Ways that to Avoid Link Theft” and there were no listings for that term.
Over the subsequent few weeks I monitored through a groundwork query on Google how many results appeared in Google for the title of my article. One week after publication there were half dozen,760 results listed in Google, a week later it was 14,one hundred and it reached a peak of 17,000 results by July twenty six, 2005.
4 weeks when publication the results in Google had fallen slightly to 16,600.
Nearly half dozen weeks when publication the results listed in Google had fallen to 44.
In a very matter of but 2 weeks the amount of search results on Google.com for the title of my article had gone from 16,600 to merely 44.
In case you are thinking this is as a result of all these alternative websites dropped by article and replaced it with alternative content I ought to add {that a} search on Yahoo.com on the same day still showed 14,300 results for my article.
What’s a lot of of those 44 results on Google, additional than [*fr1] encompass listings from the identical websites. In other words some sites have the same article duplicated on completely different pages on their website.
So Google’s Web Content Filter isn’t used to get rid of duplicate listings from the preferred websites it chooses to stay within the search results.
On August twenty eighth, 2005 8 weeks once first publication I distributed the article again to a replacement list of article sites to repeat the process. Once 6 weeks the same article had reached a peak of five,620 results on Google. But a pair of weeks later the results had fallen to 217.
On behalf of me this was dramatic proof that Google’s Duplicate Internet Content Filter is active and very effective. If you are wondering if alternative major search engines have a reproduction content filter I can ensure that Yahoo certainly does. The identical article that was once listed on fourteen,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 remove duplicate content using its Duplicate Web Content Filter.
But the query remaining is just how does Google decide which out of over sixteen,000 results does it keep and which will it reject?
I have witnessed situations where my very own articles seem in results on alternative websites, however don’t seem to be listed in the results for my own website.
So clearly Google does not take under consideration who the originator and author of the first article was when deciding that sites can remain in its search results.
It conjointly seems to own nothing to try to to with where Google 1st finds the article.
Some articles I have published to my website for several weeks before releasing them for distribution to different websites.
In that time the Google spiders have visited my site many times and Google has had enough time to see {that the} article was 1st found on my site.
It might be interesting to see if it’s possible to see what factors Google is using in its Web Content Filter to make your mind up that results to keep in its listing and which ones to remove. However that is for an additional article.
