Architects and Facebook
To build your 'likes' you have to go old school. Keep asking your friends. Ask your friends to ask their FB friends. Email your business associates with your Facebook URL and ask them to check it out and 'like' your page. Post a lot of images of you 'architecting', of your work-in-progress, of projects under construction, of details of buildings (a close-up often looks way more interesting than when seen in context).
I think that the way you have to go about building up the 'likes' for your business page points out some of the limitations of Facebook for Architects. It is pretty similar to advertising in a sports program: the people who see your ad aren't looking for an architect when they see your ad, and they may never be in the market for an architect. Facebook is a peer-to-peer network. Architects usually need a business-to-business network. Do your potential clients have a presence on FB? If you were looking for an architect, how would you go about finding one on FB?
Now, if your specialty is residential design, then you might answer those questions differently. There would be some real advantage in building a following of people who are interested in architecture and who feel connected to you through Facebook. There are some additional tips in this post about how an architect might use social media. And there are several places around the web where you can find some HOW-TOs. This is a manual that will help you start your business page.
Architects and Facebook - For many architects the peer-to-peer and business-to-consumer nature of Facebook's network is just the tool that they need. For many others who need a business-to-business network in order to be found by their potential clients, Facebook just isn't it.
