During a Google office hours hangout, Googlers received a question of whether or not to try ranking for zero search volume keywords.
“Let’s say I research on a keyword which has no volume or keyword density, but we are appearing for those keywords on the first page.
Should we target that keyword?”
Then, a Googler going by Lizzi responded:
“…You can optimize for whatever keywords you want.
And it’s not always about the keywords that have the most volume.
I would think about how people should find your page and target those keywords.”
