One SEO professional asked John Mueller during the submitted Question and Answer segment about whether Google has different algorithms per niche.
They asked: is it true that Google has different algorithms for indexing and ranking of different niches?
They have two websites of the same type. And they have built them with the same process.
The only difference is that the two sites are in different niches, and currently one site is ranking just fine, while the other one has lost all rankings.
John explained that he doesn’t believe that they have anything specific regarding different niches.
Obviously, though, different kinds of content are less critical for Google’s search results than other types of content.
John references the quality raters guidelines, where they talk about things like YMYL, or your money or your life sites.
In this case, Google does have more critical algorithms that are involved in crawling, indexing, and ranking the sites.
But, it’s not the case that it’s something where you would say perhaps a bicycle shop has entirely different algorithms than a shoe store, for example.
They are both e-commerce type stores. But, the thing that they also mentioned in the question is that these are content aggregator sites and they are built with the same process and some of them work, and some of them don’t work.
To John, this feels like it’s more of a low-effort affiliate site where you’re just taking content feeds and re-publishing them. And this is where Google’s algorithms are not as invested in this content in terms of crawling and indexing, because it’s the same content that Google has already seen elsewhere.
From this perspective, if you think this may apply to your site, John would recommend focusing on making fewer sites and making them significantly better.
This way, it’s not just aggregating content from other sources, but you’re actually providing something unique and valuable.
