Google Base

You want your site and content to appear in Google. Google base is perfect for you then.

Google Base is a place where you can easily submit all types of online and offline content, which we'll make searchable on Google (if your content isn't online yet, we'll put it there). You can describe any item you post with attributes, which will help people find it when they do related searches. In fact, based on your items' relevance, users may find them in their results for searches on Froogle, Google Maps and even our main Google web search.

Quick Facts about Google Base

• Cost: Free
• How to Submit: You can submit information about all types of online and offline content to Google Base, by either the standard web form or, if you have more than 10 items to submit, via our bulk upload options. When you submit information via the web form, you can attach up to 15 digital files in the following formats: PDF (.pdf), Microsoft Excel (.xls), Text (.txt), HTML (.html), Rich Text Format (.rtf), Word Perfect (.wpd), ASCII, Unicode and XML. Please note: the files you upload may not exceed 20 megabytes total in size, and we reserve the right to review all items in order to ensure they comply with the Google Base Terms and Conditions.
• Languages: Google Base is currently available in English and German interfaces.
• Reach: Items you submit to Google Base might be found on Google properties like Google, Froogle, and Google Maps.
• How it's different: Google Base enables you to add attributes describing your content, so that searchers can easily find it. The more popular individual attributes become, the more often we'll suggest them when others post the same items. Similarly, items that become more popular will show up as suggested item types in the Choose an existing item type drop-down menu.

I found it quite wonderful. May be you can give it a try too.
