How are They Doing with Their Own Site?:
There's a fast and reliable way to narrow down the field of real estate virtual assistant candidates that offer web design and search engine services. Go to their site and see how it looks, gets their information across and how easy it is to navigate.
Then go to the search engines and search on phrases like "real estate virtual assistant", "virtual assistant web design", "real estate virtual assistant SEO", etc. If they're not on the first page at the very least, then why let them design and manage a site for you?
What Type of Prospect Management & Followup is Provided?:
Are they able to provide lead capture mechanisms on the site, then follow up with customized drip email campaigns to work the prospects until they're ready for a transaction? How do they categorize and qualify internet prospects for assignment to agents or for more intensive followup?
Get References and Check Them Out:
The best references will be for companies with web sites that have been around for at least six months. Go to the sites and navigate around. See how they get prospects to provide their contact information. Fill out a form and see what happens. Call the company and ask them if they're happy.
Is Web Marketing a Piece of a Larger Service Offering?:
It's possible that they do have internet services that would work for you. If they also have the more traditional real estate virtual assistant office administrative and transaction management services, then the entire package might be attractive if the price is right. At least you've gathered several functions under one umbrella, cutting down on communication problems.
