We are working on an education site and have custom website built on wordpress. One component of site is blog posts and pages, sitemap for which gets built by sitemap plugin every night.
Another component is the college pages and we went live with this section 2 month back. To build the sitemap for these 8000+ pages , we wrote a program and created a sitemap lets say abc.xml. Then we submitted the sitemap to google.
After 2 months, I can see that the google acknowledged the submission but never indexed these 8000+ pages.
561 indexed pages are from our blog post and pages.
I guess the mistakes we did was that we created the sitemap of 8000+ links and submitted when we should have done it in piecemeal basis. 2nd mistake I guess is that we do not update the abc.xml sitemap regularly which we thought of doing once all the pages were indexed.
What is suggested
a) to fix this problem
b) and how to get the pages indexed ?
