Listen: Link inversion, the least known major ranking factor.

When the exact same document appears on multiple websites, Google has to decide which one is the master copy. It does this by identifying the highest-authority page as the canonical version and treating all the others as duplicates. But there is a catch. Any links pointing to those duplicate pages are redirected to count toward the canonical version instead. This process is known as link inversion. Normally, if you publish an article and smaller sites scrape your content, you keep your status as the canonical source. However, if a website with much higher authority copies your content a week later, Google might decide they are now the canonical version. Suddenly, your page is labeled a duplicate, and your own inbound links are credited to your competitor. This system is run by Percolator, an incremental indexing technology Google introduced back in 2010 to keep search results fresh. Tests show this is not just a theoretical concept. By submitting a copied page through Google Search Console, a higher-authority site can take over the canonical status of original content in less than a minute. Within a week, the original publisher's links will actually start showing up in the new owner's search console. While Google aims to serve the best results for searchers, this process can leave original publishers at a distinct disadvantage.
