Google Webmaster Tools

Google has some excellent tools for webmasters, including crawl errors, links to your site and much more.

You will need to create a XML sitemap for Google. This is easily done from SiteMap Doc. You can also make a HTML sitemap for your site. After creating your sitemap, save it as "sitemap.xml" and upload it to your site using FTP. After uploading, click on "sitemaps" in Google webmaster tools, then "Submit a Sitemap".
