什么是Impressions？
The number of times your page appeared in search results, whether or not it was clicked. Reported by tools like Google Search Console.
In SEO, an impression is counted each time one of your pages appears in a searcher's results, clicked or not. Google Search Console is the standard source, and one detail matters for reading it: an impression generally requires the listing to be in the portion of results the user actually loaded, though not necessarily scrolled into view.
Impressions are the top of the search funnel: impressions show you were seen, clicks show you were chosen, and clicks divided by impressions is your click-through rate. Rising impressions with flat clicks usually means you are ranking for more queries but too low to earn clicks, or a SERP feature is absorbing them; that is often a page one step away from meaningful traffic, worth a content refresh or a better title. Falling impressions signal lost rankings or dropped indexing, which is where to check first.
New content normally shows impressions weeks before it shows clicks, so early impression growth is the leading indicator that a page is starting to rank.
