 <p>I would advice you to generate a XML Sitemap.</p> <p>A sitemap will allows you to specify the parameters you're looking to pass to the search engine, namingly the importance (or weight) that you give to pages and the rate at which the pages (usually) are updated. </p> <p>This doesn't mean the search engines will stick to only that. It could be that you say the page updates once a year and that it gets crawled 3 times that year, or that it is set to daily, and only gets crawled once a month.</p> <p><a href="http://support.google.com/webmasters/bin/answer.py?hl=en&amp;answer=156184" rel="nofollow">Google on SiteMaps</a></p>
