I don't think the Google queries measure what the author thinks it does.
I noticed it lists 14 results from Haskell to Erlang, which I was skeptical of. When I google "move from Haskell to Erlang" or "switch from Haskell to Erlang" I do find results (such as quora questions, versus questions,lecture notes) but none of those results are the type of article we're looking for.
If they really want to do this, I think they also need to validate that some of those keywords are in the title of each page.
I'm also concerned that for some blogs, a single post might appear several times in Google's estimated search results (due to crawling the same blog under different hostnames or the same post under different paths, or because of syndication or posts to link aggregators). So maybe some individual posts reflecting particular teams' decisions are reflected 5, 10, or 100 times in the Google result count.
