Google are piloting the Google Sitemaps project – a way for you to submit a sitemap all the pages of your website in order to improve your coverage in the Google index.
The benefits of submitting a sitemap to the Google search engine are:
- all pages on your website will be found by the Google spider
- you can “push” your content to Google rather than waiting for the spider
- your page content will be fresher in the Google index
- you can provide specific information to the Google spider, such as when the page was last modified or how frequently it changes.
