Not long before Panda, I started to take a long hard look at my website. Which on the surface looked great and worked well.
But the more I dig, the more issues I find. One issue I found, was that each new user that registers, about 10 pages were created, as holders for the users content. Google followed the links via activity feeds and such.
This has resulted in hundreds of thousands of INDEXED blank pages. Even worse, if a user fails to verify, these pages are all deleted, resulting in tons and tons of 404's.
I've taken the step to noindex these user pages. But what about the tens of thousands of 404's that now exist, for users who failed to verify? Well I have 301 redirected them all to the homepage. It seemed the logical thing to do.
But did I make the right move? I cannot think of another solution, other than to allow the 404's to exist, but I think Google needs to know they're not coming back.
Hmm wotcha think?
