When considering matters pertaining to Google, it is best to go to the
source, and view the materials that Google has prepared and placed
For webmasters, Google offers this resource:
Your questions would seem to imply that you've been listed in Google
before, but are no longer listed when you do a search. This site has
three sections dedicated to reasons why a site that was formerly
listed in Google might no longer be:
Google lists several possibilities for you to consider as to why they
may no longer be listed, or disappear and reappear from Google from
time to time:
* Your pages are dynamically generated.
* You employ doorway pages.
* Your page uses frames.
* Changes from one Google index to the next may temporarily cause your
site to disappear from Google.
* Your site may not have been reachable when Google tried to crawl it
because of network or hosting problems, and was removed during the
most recent Google update.
* A technical glitch on Google's side may have caused them to 'miss'
* The contents of your page or the links pointing to your page changed
significantly and you no longer have a sufficiently high PageRank, or
your page had low PageRank to begin with and a small change caused you
to be dropped from the Google index.
* Your page was manually removed from our index, because it did not
conform with the quality standards necessary to assign accurate
PageRank (for reasons such as cloaking, writing text that can be seen
by search engines but not by users, or setting up pages/links with the
sole purpose of fooling search engines)
These reasons are explained in detail at
If you are still not listed in Google, the first thing to do is to
make sure your pages, specifically your top index page, does not
contain any of the forementioned "forbidden" techniques. If it does,
remove them and contact Google at firstname.lastname@example.org to let them know.
Otherwise, the best way to improve your Google ranking is by creating
a quality website, and convincing webmasters of other related sites to
link to yours. This will increase your site's "Pagerank" ranking
within Google, giving you a higher priority ranking on keywords
related to your site.
