I am noob (newbie) in terms of SEO, and I have been learning it since last couple of years, and still a learning process.
And I needed a way to achieve most with less or no effort (in a matter of speaking, literally you have to do a-lot off-course). So I used almost every possible SEO plugin available in wordpress.org, and every one of them is v. good, but not what or how I wanted, but since I started using SEO by YOAST, I have not looked back (though initially I was not fond of it, but it was me not plugin :D).
Its one of the must install plugins for every new website I build.
Thanks a bunch YOAST. I would not have made it so far without you ;).
