Google+ can be a beneficial part of an SEO campaign. For those who are not yet using Google Plus, it is likely because they do not know how to take advantage of the platform or misunderstand the nature of Google+ and how it can improve SEO results. There are several different ways to strategically use Google+ for SEO purposes.
Content on Google+ is treated by the search engine just like content that is on any other web page. Any content that is placed on Google+ will be indexed and can gain page rank as well as be listed in search results by Google. This can be very beneficial since about 2/3 of all searches in the United States take place on Google. It is essential to have your content searched and indexed. The posts made on Google+ will appear as search page results which manes that some of your audience may be able to find your Google+ content through a regular search on Google. The content will be online, gain in page rank, and appear in SERPs for a long period of time. It’s even possible for some of the posts to continue ranking indefinitely – even as long as a year. Most tweets only have about a 14 minute lifespan on SERPs so one year is really good real estate.
