SEO WordPress Plugin by Mervin Praison is a Powerfull Plugin which has many SEO Features. Google Authorship and Google Analytics Integration.
When I installed this plugin to check my site ,It took too much time to load.
Not working and breaking website, I surely hopes author answers, cause it is crashing my whole website... :-(
Easy and it works, though i contacted the author, but he didnt answer,,,,anyway - it works!
