Forget about the ghost town label thats been stuck on Google+. And it doesnt matter if you wont actively use Google+ (perhaps Twitter, Facebook and what else are sufficient for you). You should still create a Google+ account. Why? Because Google can display your author information, which it obtains from your Google+ profile, in its search results. This can boost your image... literally.
The search result page is no longer just hyperlinks any more. They now come with small square author pictures and the authors names below individual search results. Its nifty. Plus it also gives readers the option to visit your Google+ profile straight from a search page from which they may even start following you and click on links you post or read other articles youve written. Readers also have the option to filter their search results to only show other articles youve written.
To include author information to search results, Google has to match your Google+ profile (it has to be public) with your articles. Its not difficult to set up, as shown by this tutorial, and does not require any genius computer or coding skills, thankfully.
Author information in search results is still a Google pilot project but a quick Google search will clearly show that a number of people have already adopted itespecially bloggers. To be honest, I dont know if author information gives you an advantage (e.g. pulls in more clicks) over others in the search results battle. From my own experience however, I find that I click on those results with author information more often, even if Ive never heard of the authors.
In any case, it is becoming increasingly important to market yourself. You have to be out there networking and you have to work on your online presence and visibility. Perhaps having Google show your author information under articles youve written is a box youd want to tick.
