• Will you be advertising my home for sale in ________?
• Will you be doing ________ to let buyers know about my home?

I believe the "should I" ought to guide the "will I" with these sorts of questions.  If doing X, Y or Z is likely to result in buyers knowing about the home and purchasing it, then yes, I ought to do that.

The research above (conducted annually by the National Association of Realtors) shows that half of buyers found out about the home they bought online.  Another third of buyers found out about the home they bought from their Realtor.

Let's allow the research to guide our marketing decisions, shall we?
