It's always nice when people talk about your website. Retweets, Facebook Likes, or just emails with links help spread the word of your site and are an integral part of online marketing. However, it's also important to ask whether anyone outside your circle can find your site if they go looking. Search engine optimization like that offered by us here at FindYourSearch helps increase your exposure on all the major search engines so people can find you whether someone tells them about you or not.
