Hello Friends, I have a blog but page of my blog is not cached after 7 days so i want to revisit of crawler after three days.So what i should do for that.
For increasing crawling rate, you need to publish unique content very frequently on your blog with keyword richness and give internal linking. get some links from dofollow blogs by commenting their. submit your blog into blog directories and rss directories. ofcourse update sitemap.xml frequently and submit into google webmaster tool.
