If you are new to Google +, the concept of building circles can seem confusing. However, building circles is incredibly easy. I will give you a step by step guide to building your circles.
Think of some local businesses or organizations and search for them on Google +. Since we are in the heart of Cajun Country, I have decided to follow the University of Louisiana at Lafayette.
Now you just click follow and decide what circle you would like the page in. Its that simple.
After you have gone through and followed as many relevant pages as possible, its time to turn to the Google Communities. Communities are great because they are typically on a specific topics, such as web development. Joining these groups is beneficial because it gives you access to a group of people that are interested in a specific topic. Posting and interacting with these communities can help you gain followers and turn you into a trusted expert on your field in your community.
Make sure that when you post on your page that your content is worth reading. The more interesting your posts are the more long term followers you will have.
