Maybe your backlinks are loosing PR. indexed pages

 

- I'm not a seo expert, but I'd have thought a pr2 website has enough backlinks for indexing.

The only thing I can think of is whether or not the pages have been updated int he last 2 years. Would non-updated content get deindexed???????????

I would also guess that pointing some more backlinks at deindexed pages might make them indexed again??????? - Providing of course Google deems them to have the unique content (and enough of it) that you claim.

 

I think you are jj1 50%.But my few pages are new a month old and unique content.
