The goal isn't really to showcase your work. At least not in the beginning, your aim should be to create relationships with members of the communities you choose to join. Pay attention to relevance. Unless you join communities of your specific niche, probably you are not going to see the best results from your efforts. There are two main advantages of joining communities in your industry. It attracts a natural following without spending a dime. People will visit your page and like it.

Once you have interacted with your communities for a couple of weeks, it is time to share relevant content with them. Community moderators are often too strict on who can share his work. And if you are just a new, random person seeking for attention or an opportunity to advertise, they are likely going to kick you out of the community. But because you have already established a good relationship with your following, it should be fine to promote your work.

Content is key, and the primary goal of creating a Google+ page is to get your content out there. You obviously have many voracious readers by now, so it is best to burn the candles at both ends. Here is the idea:
Sharing content that readers want to consume not only earns you more followers and likes, but also sends social signals to your site. So, you need to have a good content sharing strategy. Your page just can't sit. The more you share content, the more your following is likely to grow.

When the dust is settled, and your content is not giving you more following, dazzle in some social signals. How? It's simple: buy real Google+ plus followers.

Most of the people on Google+ use hashtags in addition to words and phrases to search for any content. It might seem less important as compared to words and phrases but in the new Google+, hashtags are one of the ways to search for content just like the other two.
Hashtags are a simple way to track and tag conversations although they are in use mostly on Twitter and Instagram. On addition of a particular hashtag to your content, the post will now enter a series of tags. Anybody looking for information related to the hashtag can easily find your post and read, watch or listen to it.
