Do titled links that do not fit in content hurt a website? Like when people ask for reviews, or place links in their sig, sometimes they title it, maybe hoping for SEO benefits. Well, I did that , and over night i disappeared from the first page on a nice keyword. I did make a lot of changes the day before, but only to design, not any content.
I would imagine that changes to design would also make a difference... Say if you went from tables to css or some other form of design change... Google was obviously ranking you high at the time based on design and the change "upset" it slightly :0) But no doubt youll return!
i will not hurt your ranking if u post your link here in signature or for review just wait for some day it will be back in ranking it might be possible that u have changed design and due to it your page site increase so if your page size increase it might hurt the ranking
This can be qualified as a search engine spam if there are many keywords and they are unrelated. Just make it in right way.
