I've started seeing new "related searches" suggestions at the bottom of serps that suggest, at least to me, that the suggestions listed are more like popular anchor text or product speak than actual human search terms.
example: view blue widget specs
Nobody has ever looked for the word "view" in the history of my sites search function but it's the first suggestion in Google. The rest of the suggestions contain the words "review" and/or "prices" when this really isn't a niche with a lot of shopping interest involved. Less than 5% of searches on my site have contained either of those two words.
On the flip side many words I KNOW are searched for do not appear as related searches at all. Am I just lucky in my niche or are others seeing similar suggestions?
