Hey I have a question about google... i have a page with about 2K visitors a day and every page has it's own title this way "Title - Name of page their on" and there is a bout 15K pages in total on the site but google is not indexing any of them, why is this ? :/
Most plausible situation is that your content is not unique, lately google hates the copied content so it you have copied articles or any content that is not at all unique google will not bother to index your site.
You can try regular Google sitemap submission and observe over a period of time. I had faced the same problem earlier and it worked.
What if someone else copies content from your website? How does Google know who produced the content first?
Google is Big company and Google knows which site index first. On the basis of that it takes all the points.
