Google may rank sites for queries that don’t appear on the page at all
We thought we understood how Google’s reading between the lines worked, until recently we noticed that an article published on this site about how Uber’s code texts don’t keep your account safe was being returned for the queries 2109085405 and 4843218317. Maybe the phone numbers in the search queries are being related to the concepts which appear in the article, namely the concept of Uber code spam texts. And yet, if you search for Uber code text – a query the article ranks for – you don’t get those “who called me” site results.
