Why wait for the Google Crawler to index your webpages ? Use Google Sitemap. You can use the Sitemap Generator to create a XML Sitemap.
"It makes total sense to push new links to users quickly. We don't want to wait on the engine to deliver results - we want to get content into the engine faster. Whenever it's possible, we opt to push content rather than have it pulled. That gives us a more interactive experience with Google."
