Google’s Duplicate Internet Content Filter In Action
If you do not believe Google’s Duplicate Content Filter exists, I’ve got Dramatic Proof their Net content filter exists and it’s very effective.
On July five, 2005 I published an article entitled “seven Top Ways that to Avoid Link Theft” which was picked up and included as content on different websites.
Before the article was released I checked on Google whether any results already existed for the exact phrase “seven High Ways to Avoid Link Theft” and there were no listings for that term.
Over the following few weeks I monitored through a look query on Google how several results appeared in Google for the title of my article. One week after publication there have been vi,760 results listed in Google, per week later it absolutely was 14,100 and it reached a peak of 17,000 results by July 26, 2005.
four weeks once publication the results in Google had fallen slightly to 16,600.
Nearly 6 weeks when publication the results listed in Google had fallen to 44.
During a matter of but 2 weeks the quantity of search results on Google.com for the title of my article had gone from 16,600 to simply 44.
In case you’re thinking this can be as a result of of these alternative websites dropped by article and replaced it with alternative content I ought to add {that a} search on Yahoo.com on the identical day still showed fourteen,three hundred results for my article.
What’s additional of those 44 results on Google, additional than half include listings from the same websites. In different 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 popular websites it chooses to keep within the search results.
On August twenty eighth, 2005 eight weeks once 1st publication I distributed the article once more to a replacement list of article sites to repeat the process. Once 6 weeks the identical article had reached a peak of 5,620 results on Google. Less than a pair of weeks later the results had fallen to 217.
For me this was dramatic proof that Google’s Duplicate Internet 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 certainly does. The identical article that was once listed on fourteen,three hundred sites on Yahoo, has fallen to 344 over the same time period.
From these results it would seem Google takes regarding half dozen to 8 weeks to get rid of duplicate content using its Duplicate Web Content Filter.
But the query remaining is simply how will Google decide which out of over 16,000 results does it keep and that will it reject?
I’ve got witnessed situations where my very own articles seem in results on other websites, however aren’t listed in the results for my own website.
Therefore clearly Google does not take under consideration who the originator and author of the initial article was when deciding that sites can remain in its search results.
It conjointly seems to have nothing to do with where Google initial finds the article.
Some articles I’ve got published to my website for several weeks before releasing them for distribution to different websites.
In that time the Google spiders have visited my web site several times and Google has had enough time to figure out {that the} article was 1st found on my site.
It would be interesting to see if it’s attainable to determine what factors Google is using in its Internet Content Filter to decide that results to keep in its listing and that ones to remove. But that’s for an additional article.
