i have a wordpress hosted site blog which is not cached yet after 2 months i have done bookmarking too and posting contents regularly. will someone could tell me what is the reason for that.
Try to create backlinks to your blog by article submissions, directory submissions and forum participation. Within no time your blog would be crawled but it might take sometime before it is indexed in search engines result pages. Also make sure that you did not block search engines from crawling your blog in your blog settings.
Make sure your blog contains code that allows robots to crawl it, try some blog commenting and forum postings will help you.
check your robots.txt file. maybe you've set and restricted search engine robots to access and crawl your site
usually normal.. as long as your blog is indexed by G there is nothing to worry about.. i suggest to continue building more links..
did you even submitted your sitemap to Google webmaster tools? https://www.google.com/webmasters/tools/
