Return to G-SERPs
AKA ‘bounce back to search’.
Google will most likely monitor a user’s behavior based on how quickly they appear to have abandoned a particular site.
If a user makes a search and decides to enter a website by selecting the link in Google Search Results Pages (G-SERPs), but then returns back to actively using engaging in the search results within seconds, then this may be seen as a negative factor for the first clicked result.
Compare this with Google Analytics bounce rates and what I have to say about that.
While I don’t think this is a very reliable indicator, if a website repeatedly demonstrates that a quick return to SERPs is not unusual for that site, then it builds a pattern of behavior that is indicative of something probably not positive.
