What can be the reason behind getting a partial status in webmaster when submitting only few blogs?

The Fetch as Google tool enables you to test how Google crawls or renders a URL on your site. You can use Fetch as Google to see whether Googlebot can access a page on your site, how it renders the page, and whether any page resources (such as images or scripts) are blocked to Googlebot. This tool simulates a crawl and render execution as done in Google's normal crawling and rendering process, and is useful for debugging crawl issues on your site.
