I created a MerchantCircle account a very long time ago and at first did not see any value in it. Today, my account as a Google rank of 3. It's not the best of the best, but it points to all my main websites, such as Snap!, equally increasing their rank and this without having to do much work, really!
Link from your site
First, assuming you are a small business, you want to add a link from your main website to your MerchantCircle account. This will send some traffic to your MerchantCircle account and end up in some people connecting with you.
For this purpose, you can use your MerchantCircle vanity URL. This is done by going to your Dashboard and after clicking on Business Information, scroll down to Website Links (at this time, the last entry on the page) and then click the Edit link. Here you are given a way to enter two links: your main website and your Custom Link (or vanity link). In there, enter your preferred alias. In general, the best is your business domain name. Say your business website is http://www.example.com/ then use example. Finally, hit Save.
