Optimal application: You can check the movement of SERP at a glance. In particular, it helps you monitor your competitors for focus keywords.
The SERP Trends Chrome extension is a smart tool that emphasizes the movement of search results within a search page. You can enter a focus keyword in Google or Bing to see if your website has moved up or down in SERP or has just been displayed. You can also see how many positions your website has increased or decreased compared to the previous day.
