If an agent tells you that they are going to get you an email each week with the website activity then does not do so, I would put them on the spot immediatly.
Actually speaking with a showing agent live and trying to get feedback is a tough one. You see, many agents work between the hours of 8 AM and 8 or 9 PM. (That is not to say that they are working 13 hour days.) This is simply to illustrate that it is tough to know every agents schedule or when it is best to reach them for feedback. In addition, some agents really do show 5-15 properties at a time and it is hard to devote an hour or more to call every listing agent back to let them know that the buyer is interested or not. (I can tell you that as far as feeback goes, no buyer feels responsible to let a seller know exactly why the will or may not buy their home. In part because a buyer may have decided to keep looking.) Buyers don't always look at homes and say... "Yes, I want to buy this one or No, this is not the one." Many want to see 20-30 or 40 homes before even thinking about making a decision.
The loudest feedback a seller can receive is an offer or NO offer. AND a an abundance of activity or no activity. The lack of activity is your feedback to add more amenities, square footage, or lower the price. Buyers are only looking at homes that on paper (Their printouts) are obviously priced fairly. Once they view a few homes, they will determin if they want to go back to any for a second look at any of the ones that they have already seen. Sometimes a buyer needs to see more in order to really get the picture that your home is a true value. Once they look at other homes... if they don't come back, they may have found a better value somewhere else. It's best to price your home approx 2% below your competition to get a good amount of traffic.
