Google sometimes has problems indexing a site correctly. Or they may not be indexing your site at all.
How do you know if your site is indexed? MarketLeap has a wicked tool to help show how many pages have been indexed by what search engines: MarketLeap.com index tool. If HotBot has 100 and Google has 30 and MSN has 1,000, then you have a problem when it comes to Google. Note: MSN usually has a very high indexing number.
If you are unsatisfied with the level Google has indexed your site, there are ways to rectify this issue. Please contact Muller Digital directly for more information.
