Hello all In my website (www.startsmiling.com), i add some plugin like "addthis" and "Wibiyo" , Will it affect my Organic result, Page Rank, etc...?
No, these are just plugins to add some functionality and these won't make any change in your search engine visibility. So you can use it without ant tension
No, they won't affect your serp directly. But in somehow they can help if your visitor has shared your website to their social bookmarking profiles.
