today a friend of mine asked me new new Baidu and Google today launched a Web site the day before yesterday are included, but site:www.***.com we found the site while Baidu Google is included but Home page site title and site description displayed in search results are incomplete, site snapshots cannot be previewed, behind the Google cached at all. That is what causes it?
Hefei SEO think Baidu, Google does not show title and description for two reasons:
1. site in the site's robots.txt file before setting the prohibition of all search engine site, but these pages may still appear in the Baidu search results , But your content is not crawled on a Web page, into the index and display, in Baidu search results display only descriptions of the other pages on your Web site. Robots unlock prohibited crawl status, take some time to take effect.
2. why it might be because of site design or system exception causes the tag title extraction fails, the search engine can extract some text from elsewhere as a title.
