Why is my page not indexed?

[dennis123]

Hi Friends,
Google doesn't crawl all the pages on the web, and we don't index all the pages we crawl. It's perfectly normal for not all the pages on a site to be indexed. Read more about how to tell us about your site. If your site used to be indexed, but no longer is, you can read more about possible reasons for this.

Google will not index some pages on your site because it can't crawl them. Even though it can't crawl them, it can still see them. To identify these crawl errors, go to Google Webmaster Tools → Select your site, → Click on “Crawl” → Click on “Crawl Errors
