If there is a way to fix this, I would like to know.
sort by best latest
I know what you mean. My related searches are about "valentine's day" stuff and "love." None of my hubs deal with that subject matter or are that mushy in tone. I hope these searches aren't misdirecting traffic.
I think it is the title, and not the hub itself. If you tweak the title the related hubs will change. Sometimes it is not worth it, of course.
