Google Ads glossary
The SERP, short for search engine results page, is the page a search engine shows after a query: ads, organic results and other blocks.
The page changes with the query, the country, the device and the city, so two people do not always see the same one.
The SERP is the best clue to the intent of a search: it shows how Google understood the query. Reading the page before you bid costs less than finding out by paying for its clicks.
Should I Bid does that reading for you: it reads the live results page, then the pages that rank on it, and returns a verdict for each keyword. Our guide Who is bidding on my keywords shows how to read it by hand.
If a keyword’s page shows Shopping ads with a photo and a price, Google ties that search to a product people buy. If it shows no ads and mostly articles and definitions, the search more likely comes from people who want to understand.
