I typed in: "days in a year" and got the response from google but absolutely no results on the serp page! Does this mean we can't use it as a keyword? Just an interesting find.
I get alots of results from Google when searching for that! Maybe you've changed something in your preferences?
Well this is what I get: 1 year = 365.242199 days More about calculator. Search for documents containing the terms days in a year. And i've never changed any preferences.. after click the link, then I see results Or if I search : "+days in a year"
