Single Viral post can help entire site's SEO??

[Paul]

Its always a good thing if one of your post gets viral. It means that you are getting noticed. Try to build as much as internal links from that page. But don't make it overcrowded as that will definitely effect you negatively. As, one of your posts have gone viral so there is a possibility that your new posts will also get a positive response so work hard in them. Make those posts useful for your users, if they likes then you don't have to worry about the search engines.
