Welcome to the Q&A Forum

Yeah, that kinda display trick is transparent to the googleBot....i.e. it's for users not bots...so it's not an issue...use them as you see fit...

Their content is mediocre at best. Lot's of grammar and spelling errors from a supposedly us/uk staff.

I tend to follow the rule of thumb that states, if you have a close match to a page being removed, then setup a 301 there. If not, it is better to remove it altogether and give it a 410 (Gone) rather than a 404 (Not Found). I hope that helps a little. -Andy
