I research a lot in word press and got a useful tool that can enforce the Seo Optimisation in easy way. I am talking about the SEO Yoast, Well it’s a powerful plug-in that enables the user to optimize its website easy. You can change your Meta title, Meta description and Meta keywords. It also indicates the use of keywords in text body on website.
I recommend you to use meta title, description but not the meta keywords as It becomes the old fashion and can not be focused by search engine.
