Hello. i built many blogs which link back to my website:babatek.com. and many of them have about 100 pages indexed in google. but yesterday, almost all blogs suddenly gone out of google's indexed. i wonder if i need remove those blogs or just wait for some time. or my website will be penalized by google. please give me a suggestion. thank you.
If your main site is legitimate site you must not worried. Because you can't be penalized because of other site was linked to yours. But if the main site also looks spammy, then its a matter of time before google removed the site as well.
the contents for my blogs are the products information of my website:babatek.com, i think google conside which are spammer? but it is not before?
maybe they just got sandboxed and are coming back into the index in a while. I wouldnt worry too much.
