I have been experiencing a big problem with my website where Google has not been listing many of its pages. This problem has only occurred in the last year or two as previously if i added any new content Google will list these new pages within a few hours.
I know that Google have been trawling my website as they have been adding some pages but not all of the pages which I find strange. There maybe thousands of pages that have not been listed so far and this continues to be a big problem.
I have also recently received a message from Google saying that they are penalizing the website for what they describe as links that do not fall between their firm guidelines.
I believe that the problem with Google not listing pages from my website occured a long while before we received this message from Google.
Does anyone know what can be done about this problem? And what can be done to fix this issue?
Any help would be most welcome.
