Google's Duplicate Content Filter: Proof in Action
If you've ever doubted the existence of Google's Duplicate Content Filter, I have compelling evidence that not only does it exist, but it's also highly effective.
On July 5, 2005, I published an article titled "7 Top Ways to Avoid Link Theft." Before releasing it, I checked Google for any existing results using the exact phrase?"and found none. Once the article was live, I monitored its visibility on Google. A week post-publication, Google showed 6,760 results for the article's title. A week later, it jumped to 14,100, eventually peaking at 17,000 by July 26, 2005.
However, four weeks after publication, results dipped to 16,600. By nearly six weeks, they plummeted to just 44. In less than two weeks, Google results for the article dropped from 16,600 to a mere 44.
You might assume other websites removed the article, but Yahoo still listed it on 14,300 sites on the same day. Strikingly, more than half of the 44 results on Google stemmed from the same websites, with duplicated listings across different pages.
This indicates that Google's Content Filter selectively removes duplicates, but not uniformly across all sites. On August 28, 2005?"eight weeks after the initial release?"I redistributed the article to new platforms. Six weeks in, Google listed 5,620 results, which fell to 217 in less than two weeks.
This clearly demonstrated Google's active and effective Duplicate Content Filter. Yahoo displayed similar behavior: its 14,300 listings decreased to 344 over the same timeframe.
Google typically takes about 6 to 8 weeks to eliminate duplicate content, but how does it decide which results to keep? I've observed instances where my articles appear on other websites but not on my own. Apparently, Google does not prioritize the original author's site when filtering results.
It also doesn't necessarily matter where Google first encounters the article. I've held some articles on my website for weeks before broader distribution, allowing Google ample time to identify my site as the source.
Understanding the factors Google considers in its Content Filter could be a topic for further exploration. However, for now, the evidence is clear: Google's filter is very much active and influential in shaping search results.
