Did you know that Google Plus is a DoFollow site? Oh yes and not only is it dofollow but it's anchor text backlinks coming from a Page Rank 8 site. This is great news for the Search Engine Optimization community. These free anchor text dofollow links are a gift from the Google gods! Google Plus allows multiple anchor text links in your profile and your +1's are also dofollow. For those who are not familiar with the NoFollow and DoFollow concept here is a quick break down.
NoFollow and DoFollow Definition:
If a site is DoFollow, then links to external sites are acknowledged by search engines and get credit for being linked to (which helps search engine ranking and authority). If a site uses NoFollow tags within links, search engines do not acknowledge the links to the external site.
Facebook and Twitter are both nofollow which puts Google Plus ahead from an SEO perspective. This does not diminish Facebook and Twitters social marketing capabilities at all as both sites are great for traffic and building brands, but Google Plus ties both the social and search engine marketing together. Google recently launched their +1 (plus one) feature where users can "plus" or "like" a web page or website in the search results. The user's plus ones are stored on their Google Plus profiles where it's visible to their contacts and friends.
Google Plus Ones are similar to Facebook Likes but would have a greater affect, specifically on how websites are going to be ranked. Obviously the more plus ones a website has the better it will rank in Google's search engine results. And much like Facebook Likes it will be shared with a user's friends and followers which is a big influence, as people tend to trust what their friends or contacts recommend. So if 10,000 users have +1'd your website Google will definitely rank you well!
It is now important for businesses and website owners to have Google +1 buttons on their websites and to have a Google Plus profile. This will ensure users can easily +1 your site and you can take advantage of the dollow backlinks. If you're not a member of Google Plus as yet, Get a Google Plus invite here.
