If you aren’t taking advantage of the social media universe to promote your site, you are missing a big opportunity to connect with your target audience.
Furthermore, most search engine optimization experts agree that you may also be harming your site ranking. Google has said that they look at social networking “signals” to determine the relevancy and popularity of websites in connection to keywords. So it’s important that you climb onto the social web bandwagon.
At the very least you should have some “like” or “tweet” icons in the footer, header or sidebar of each page. Facebook and Twitter are the twin “gold standard” of social media. Ideally, you should also create your own Facebook Page or Twitter account with icons linking to each.
