Video SEO is a great way to build in-bound links to your websites.
To help them go viral, share with your friends on social networks. I just completed one for a Raleigh Pool Contractor, Mr. Jim Hinson as an example. The videos don't need to be long and fancy. Rather, they should be short and to the point with relevant content, and a link back to your website.
In this example, the video links back to the website of Raleigh Swimming Pool Contractor, Jim Hinson. He is the Triangle area's Premier Gunite Inground Swimming Pool builder.
