1. Does G00gle think your site has "fresh" content based on how many times you submit your sitemap with same content? or how many times you submit your sitemap with different content? 2. If I submit my sitemaps at faster rates, does G00gle crawl my site more frequently? Or does it only crawl my site more frequently if it sees more frequent changes in content? 3. If I change like 5 words in my webpage, does G00gle consider that "fresh" content? If not, then how much do I have to change so G00gle thinks it's fresh??
