One of the best ways to get traffic from Google is with SEO which is search engine optimization. When someone is searching on Google for something using specific keywords, for example: How to make money with Facebook, your website should appear on the first page of search results. That is, if you have a website promoting a product that explains making money with Facebook.
In order to have your website on the first page of Google, your website should first be indexed. And the fastest way to have your website indexed by Google is having a Google Plus page. Google Plus was first created as a social network to compete with Facebook. Facebook now is the number one social network in the world with the most users and visitors. Even though Facebook can help you rank higher in Google search, Google Plus will almost instantly rank your website on the first page and the more plus ones you have, the higher your website is ranked.
If you have a product to promote then I would definitely recommend for you to create a Google Plus page, gain a following and join some communities related to your niche. Once you join a community you can post an article on their page and get a lot of traffic to your website. Even though Google Plus is still in its early stages, I think it has a lot of potential to beat Facebook, Twitter and all the other social networks when it comes to targeted traffic.
