Determine and set a budget that you can stick to.
Even with the immediate visitor traffic generated, know that the few that will eventually become clients will probably not do so for months in the future. Don't set a high budget that you'll need to cancel in three months. Be realistic and budget for at least a year's traffic to begin to see commissions results.
Do your keyword research and look for niches.
Since pay per click advertising is bidding against your competitors for the top positions, it can get expensive if you just compete for the top and most-used phrases. Look for less-used words and phrases and you can frequently get top exposure for much less.
Take the visitor to the right highly-relevant page.
If they click on an ad to search all listings in your area, take them straight to the listings search page. You can have links back to home and other pages there. This more direct approach is appreciated and you won't lose that visitor that leaves your home page when they can't quickly find the link to what they wanted.
Think twice about requiring registration to search listings.
Write your ads to catch their eye and interest.
Think of what the searcher is wanting. An ad touting "I give the best buyer agency service in town!" doesn't cut it. "Find all YourTown listings here" does. Note the use of the word "find" instead of search. It's proven to work better, as they want to locate homes, not search for them.
If you don't have a friendly way to get their email address, STOP NOW!
If you don't have special offerings over and above property searches to generate voluntary sign-ups, you're wasting your advertising dollars. Visitors will be glad to use your site over and over without ever letting you know who they are. Offer statistics or other special reports if they'll fill out a form to have them emailed.
Don't Waste that Valuable Contact Information.
Even if you get the visitor to value your site and information enough to provide their email address, you can't expect them to act soon or remain loyal until they do. Implement an effective and non-intrusive drip email campaign. You need to continue to be valued for your helpful attitude and low-key service approach.
