I was waiting for google to crawl my website automatically without out
having to submit a site map. It never happened so. I was wondering how
long does it take for google to index a website once site map is submitted.
Here are a few answers i found on the web.
New website with no or few external links and is not updated frequently:
Popular site with lots of links and has been around for years and is updated on
a regular bases: Indexed Everyday or several times a day (news sites).
Tip: Try getting as many links as possible. Even start dropping a link to your site
sites like Yahoo answers will help
If you can, link your new website from another site already in the google index.
creating a google site map, it may or may not help you get listed faster but it won't hurt.
