User signals are behavioral patterns of users which Google uses to establish the rankings of your website in the search results. For instance: users click on a result in the search engines and after that, they immediately bounce back to Google. This is a signal that the website does not fit the search query of the user. Google uses this type of information to estimate what results are useful to show to people searching with a specific search query.
The most important user signals
The most important user signals are the bounce rate and the click-through rate (CTR). These are important for your SEO, as Google takes these seriously. But besides that, these user signals are also important for your user experience. Let’s look at these two user signals in more detail.
Your bounce rate is determined by the amount of people that click on the link to your website in the search engine result pages (SERPs) and consequently click back again to Google. A high bounce rate indicates that people did not find what they were looking for on your website.
Click Through Rate (CTR)
The click through rate (CTR) of a page is determined by the number of people that click on your result in the SERPs. If your snippet is very appealing to a user, or appears in a higher position, people are more inclined to click on it. The more people click on your result (and not on the other snippets in the SERPs), the more Google will think your result does indeed fit the search query of the user best. A high CTR will therefore result in higher rankings, as Google wants to show the best result first.
Other user signals
Other examples of user signals are the time spent on a website or the percentage of users that return to your website. You can monitor those with tools like Google Analytics as well.
