Therefore Google launched a fresh crawl briefly visited sites on the Internet more frequently than the deep crawl. It’s fresh crawl results will not change the overall index held Google, but will update the contents of some web / blog. Google did not announce the schedule and the fresh crawl your site / blog what was targeted, but the webmaster can find out the schedule through a thorough investigation.
Google has no obligation to visit any particular URL, with a fresh crawl them. These sites and blogs can increase the opportunity for more frequent visits Google to update their content regularly. Remember the shallowness of the fresh crawl, Google may visit the front page of your site or blog, but probably not visiting other pages.
