For SMM of my site i want to use Plus. How should i start. Should I create page or plus my posts. Please give me a view.
The best way is to put a link to your site in your G+ profile, then comment on other people's posts and interact. They'll naturally check out your profile and visit your site then.
Creating a page seems to be the best way to go about it. You also have to update it regularly. From what I know it is kind of like a facebook page in a way. You want to update the page with content often. A G+ page seems good for SEO and indexing. Since G+ is a social media site, you should try to interact with other G+ members. Communities might be a good way to go about this. You might be able to promote some of your own work or blog posts through communities too. Just don't be a spammer. Comment on other people's posts too.
I think all the above ideas are great. I do a combination of +1-ing posts I like and posting my own messages. I also recruit other people to share my items on their pages.
With G+, you can create your business page and that makes sense also because you would not want to mix your personal friends and website users in the same account. It is better to have a separate page for your site. Share your posts there and add more and more users.
Make G+ page of your business. Get more and more followers. Write engaging content. Reshare and comment on other's posts. Add a G+ widget on your site's home page. Contribute in communities having same niche as yours.
getting more followers in not necessarily the best option. If you are a local business or based in one country then it would be by far much better to work on that following, which of course is a lot more difficult. Likelihood is most g+ users are from India at present or Asia. So if you are selling flowers in London and have hundreds of +'s from or people in circles from India it really makes no sense.
Create a Google + page for your business and link it your website. You can also link your blogs and other pages to your Google + profile.
