How Can We Make Google Crawl our webSite More Often

• Update content frequently

• If you have a blog, ping Google automatically

• Maintain the server in a highly available healthy state

• Put backlinks to updated content on forums (like Yahoo! answers)

• Make site pages available as RSS feeds and distribute them

• Create a dynamically generated XML sitemap

• Use social bookmarking sites like Digg

• Pagerank and authority of the site

The Google webmasters tool has a crawl rate option, but that will be useful only when the “Faster” option is available to you, which would not happen unless yours is a high authority site.
