I wanted to add specific social buttons to my article.
I used ShareThis. It gives a facebook like button, google plus button, etc... by default.
were as in other articles of different modules i had integrated the facebook like by myself by following the documentation (including markup in the head section)
What is the difference in adding manually with many markups and using third party code?
Will that affect SEO or any other advantage over the respective social networking site (here for example facebook and google plus)?
