As long as we see the spider Daily care of our site, we can analyze whether spiders like our site. is included and put out is only a matter of time.

Second: You can see when spiders come to our site, crawling the site of those pages, there is no successful crawling, and included. Whether to encounter dead links, such as Crawling back code is: 404, then this link is dead link, the return code is 200, is a successful crawl, 200 2869 1156 Such code is successful crawling and included, 200 0 0 is the success of crawling but does not indicate that there are included; If the return code is 304, there is no new content, and so on.
