1. The basics
Google is a fully automated search engine, which employs robots
known as 'spiders' to crawl the web on a monthly basis and find
sites for inclusion in the Google index. It is NOT necessary to
submit your site to Google in order to be included in their index.
In fact, the vast majority of sites listed are not manually submitted
for inclusion.
2. Submitting your site
Google add thousands of new sites to their index each time they
crawl the Web, but if you like, you may submit your URL as well.
Submission is not necessary and does not guarantee inclusion in
our index. However, they DO NOT add all submitted URLs to their
index, and cannot predict when or if they will appear.
Please visit google's "Add
URL" page to input your URLs. You can submit your site
as often as you like, but multiple submissions will not improve
the likelihood of your site being added or accelerate the process.
The best way to ensure Google finds your site is for your page
to be linked from lots of pages on other sites. Google's robots
jump from page to page on the Web via hyperlinks, so the more
sites that link to you, the more likely it is that Google'll find
you quickly.
3. What else can I do to get listed in Google?
Google partners on the Web include Yahoo! and Netscape. If you
are having difficulty getting listed in the Google index, you
may want to consider submitting your site to either or both of
these directories. You can submit to Yahoo! by visiting http://docs.yahoo.com/info/suggest/.
You can submit your site to Netscape's Open Directory Project
(DMOZ) by visiting www.dmoz.org. Once your site is included in
either of these directories, Google will often index your site
within six to eight weeks.
