Ditto to all the good advice already given about staying active here....and being consistant.
I don't pay for zip codes (sorry trulia!) or to be a Pro anymore....and I still have done a good deal of business that was generated by my presence here.
Here are a few other random thoughts of mine...........
Treat your answers as though you are building a library of advice - because you are, and consumers WILL look back at what you have said in the past.
When you respond to a question.........ANSWER the question!
Do not lecture the consumer or try to show them the "light" or chastise them, for example, for wanting to be a fsbo...imo...it doesn't enhance your image to critique them or offer stagnant, trite responses ("you get what you pay for", "why rent when you can buy", "now is the best time to buy/sell", etc).
Respect the poster and the question, and give a HELPFUL answer...or don't answer it at all.
Do not use questions as an opportunity for self-promotion!
I doubt very much consumers understand or care about a long list awards following your name....and they certainly don't get excited about a repsonse that simply says: "CALL ME".
Ok, I am done lecturing now!
(and a little humor thrown in here and there doesn't hurt either!)
Good luck to you!
