I have several sites that I do SEO for that are having a common problem. I have submitted xml sitemaps to Google for each site, and as new pages are added to the site, they are added to the xml sitemap. To make sure new pages are being indexed, I check the number of pages that have been indexed vs. the number of pages submitted by the xml sitemap every week. For weeks now, the number of pages submitted has increased, but the number of pages actually indexed has not changed. I have done searches on Google for the new pages and they are always added to the index, but the number of indexed pages is still not changing. My initial thought was as new pages are added to the index, old ones are being dropped. But I can't find evidence of that, or understand why that would be the case. Any ideas on why this is happening? Or am I worrying about something that I shouldn't even be concerned with since new pages are being indexed?
