SEO testing would have indexed it as a ranking factor and already made millions of dollars on it. Second, a high CTR does not reflect the quality of the page you will land on. It talks about your approach to writing titles and meta descriptions, as well as branding. We also have statements from Google ranking engineer Paul Haahr on how Google works. He gave the related presentation at SMX West in March 2015. In it, he explains how Google uses a variety of user engagement metrics in ranking. The result is that he stated that they are NOT used as a direct ranking factor,
but rather are used in periodic quality control checks of other ranking factors they use. How Google uses CTR as a ranking factor Here is a summary of what his statements imply: CTR and similar signals are NOT a direct ranking factor. Signals like content and link jewelry retouching service quality, and algorithms like Panda, Penguin, and probably hundreds of others are what they use instead (the “Core Signal Set”). Google runs a number of quality control tests on search quality. These include CTR and other direct measures of user engagement. Based on the results of these tests,
Google will adjust the base signal set to improve the test results. The reason for this process is that it allows Google to run its quality control tests in a controlled environment where they are not easily subjected to algorithmic play, and this makes it much more difficult for black SEOs to manipulate. -hat. Is Larry Kim right? Or Paul Haahr? I do not know. Let's go back for a moment to John Mueller's comments Looking back on John Mueller's statement I shared above, it strongly implies that there is a cumulative impact over time of generating "lots of different signals that tell us this isn't is probably not such a good site”.
