I think you can create a new page with professional cover photo, profile pic and all info. after creating the page you should integrated with your website which will be very useful and effective for SEO.

remember one thing without activity and followers it will not serve good SEO purpose. so you should add followers. but how you will add followers? some people are provide followers at very cheap rate in online. dont hire them because they are use bot. You have to find some who provide real followers. Recently i used this gig for my page. you can try, its only about 5$.

let me know if you want to more about google plus.

thanks

Why would you delete your current profile? You can start a new *page" under your current profile if you want, but all your authorship info is on the profile level. The only reason to start a new profile is if you wish to use a different email address with it. You don't need a new account to get Authorship, will work perfectly fine with your current profile.

I dont know anyone using google+

you can continue with your currently running account.

I have been on Google+ for the past few months, I added various people, commented on various topics and overall just used it recreationally.

I am now publishing some posts on my wordpress website and I was advised to sign up with Google Authorship for SEO etc. I was thinking it would be better to start a fresh new Google+ page and delete the old one.

I just wanted to know would it cause any issues being a new account or should I go ahead with it.

Thanks.
