Please give me some idea of page indexing on google,yahoo,msn or other measure search engine, I have <1000 page on my website but 15 page are not be index. I know this is a big issue for seo optimization. So can you give me some idea.
If pages are not indexed yet - there is internal problem. May be - duplicate content from other site of banned site in the past.
I suggest you to consider a canonical and check for webmaster tool by google. Update your sitemap and submit again.
yes dude this is an interla problem of your site, as only 15 pages are not being cached in google.those 15 pages might be having dupliace contents or some linking issues.And thats the only raeson your all pages ar being indexed besides these.Try to edit them and submit again to google.
I'm not sure if I really understood your question? lol. Create a XML sitemap, that will ultimately help you get your '1000' pages get indexed over time.
try to define canonical in your duplicate content pages and do some proper submission in social bookmarking sites and article submission sites.
If you are not having any internal problem, i can suggest you that to do some of do follow bookmarking submission to that page. Hope it will be helpful to you.
