I have been doing some research on google plus lately, its going to be one of the easiest ways to get our sites indexed. Every story i published to google plus was indexed within 10 minutes! I have a great tip here.. Do keyword research in your niche, find the keywords that have less than 10,000 in competition. Write a quality plus post, add your keywords etc. link it to your site. (make it easy to read, and put emphasis on your keywords by bolding them with a * on each end.) I tested this a few times and i found that depending on how heavy the competition is in 10000, my story actually hit first page. Also i think it could drive some great traffic, there is no alot of competition in plus right now, so add your company or keywords to your education, work place, and tagline. You will show up in the search results on google plus! However you wont stay in page 1, they change on a daily basis, you will cycle through it. it's a great tool for SEO, if your not using it than your behind your competition. Do a little research into it, im not going to reveal what keywords i used to rank within 20 minutes for obvious reason. It can drive some traffic!
