Why should change the website title

Why should change the website title, the reason only one of untunk increase the visibility of a blog or website, it's hard to raise the visibility of blogs that are currently in the grip google. because some time ago I tried to examine some serp seo for my blog it is not suitable, and the most disturbing thing this blog is a site that really bothered me because almost the entire contents of my site there is a copy paste, which I think screwed up special serpseo ini.Jika titelnya blog turned into Learning SEO Google is my more learned seo for google, I was going to change the title to learn seo wordpress but not so because the title is already used by a friend of my seo. Hopefully with the new title of Google SEO Learning for Education can give my experience in playing online seo as a beginner like me
