“Properties Online and Listing Domains are important parts of my marketing strategy for commercial real estate. As I sell in three states, I need products that are easy to set up and use, and, also work hard to drive traffic to my listings. I have looked at a number of products over the years, and those of Properties Online stand out. I particularly like, and use frequently, two unique products that no one else offers. 1.) I can add pictures and information easily to my listing and then generate a flyer that contains an embedded hyperlink pointing back to my website listing page. This flyer can easily be emailed to an individual client or sent to my CRM system to email out to hundreds of my contacts with nearly one click. Some services may offer flyers but not with the embedded hyperlink. 2.) I can set up a monthly PDF report to be sent automatically to my client showing the views per day and unique pageviews (complete with a bar graph of a history of monthly activity), as well as other statistical information. This monthly email keeps my client informed with the statistical details that they need and frees me up from report generation. I have found the products from Properties Online bring value to my own business, routinely recommend them to other agents, and would highly recommend them to you.”

“Properties Online has helped me practically build an Internet Empire! I set up a listing domain website for each listing I take, including a narrated video tour as often as possible. This combination of domain name/website/video has helped me continually get more listings and sell more properties. Properties Online is probably one of the main reasons I have been so successful in my market. When I need help, the staff is more than responsive, and sometimes they are so fast that my problem is resolved before I am even off the phone. On a scale of 1 to 5, I would rate their customer services at 6+! Not only does the staff care about solving a problem, they are interested and helpful, even when I try to incorporate other items into the websites that weren’t necessarily part of their original design. I keep the property websites active, even after the property is sold, for search engine benefits. I consider Listing Domains and Properties Online to be an important part of my marketing strategy and a key partner to my own success.”

“Listing Domains and Properties Online is a great point of difference when competing for listings. Sellers are impressed with the fact their property being viewed by potential buyers without having to share the spotlight with other listings. Each of my agents sets up a website using Listing Domains for each and every listing. I particularly like the visitors’ report as it shows the number of times the listing has been viewed online. I use this data to track promotional activity and when reporting market activity with sellers, especially when it is time to make a price adjustment. The auto send feature of the traffic report is easy to set up and routinely keeps our clients informed. When we have had a questions on a product, the response from customer service has been almost immediate.”

“I love the products at Properties Online and use the Website Builder, Listing Domains, Virtuet, and of course the Smart Lead Capture for text for more info. I find the applications so easy and intuitive to use that I have never even had to watch a video tutorial. In my busy day, I need to use products that are easy to set up and work hard to market my listings. I found that combination at Properties Online. I love the statistics supplied from Smart Lead Capture and use the email addresses I get from it for my drip campaigns. As for customer service, wow, they are fabulous! I get return calls after hours and usually in one hour or less. Their support staff is very responsive. Pricing for the products is excellent and beats the others I reviewed when I did my first site years ago. No need to shop around for price now as their exceptional customer service has made me a loyal longtime customer.”

This website tool has grown our business tremendously…

“We had been working with a website company that our brand recommended. We had very little customer service and the way we had to “build” the website wasn’t very easy. I researched a lot of companies and was looking for ease of operation and quick response from technical support. I decided to go with for ease of use, quick response, and email updates. This website tool has grown our business tremendously over the last year and a half and we have and would recommend it in the future.”

– Matt McLeod, Company

Enormously contributed to the success of MY business!

“As a real estate agent, it is important to continue image branding and to generate new business. When creating my website, I spent several months thoroughly searching for, evaluating, and comparing numerous website design firms. Ultimately, I selected, and I can honestly say that it is one of THE BEST decisions!

Besides being the most professional, efficient and economical choice, I was struck by impeccable personalized service and attention to detail. Throughout the years, they REALLY listened to my needs, desires and input, then augmented it with their own fabulous creativity to create a site that has truly exceeded expectations…without busting my budget!

Their services are exceptional and, without a doubt, they have remained a “step ahead” of feature development. I could not be more satisfied. The results they have yielded have enormously contributed to the success of MY business! Thanks again for everything! You’re terrific!”

– Kat McDowell, CENTUYR 21 Alliance

“Thanks again for you and your team’s help as I set up my latest website to promote one of my listings. As usual, I found that working with Listing Domains was easy and efficient.

The red-on-white sign riders catch the eye of prospects, who remember to visit the website once they return to a computer. The websites’ clean and clear designs allow the prospects to instantly see a slideshow of photos and read the details of each listing, as well as request more information, schedule a tour, or view my other listings.

I’ve captured plenty of new buyer (and seller!) traffic simply through adding a Listing Domains rider to each of my yard signs. Many prospects are so impressed by the internet presence that they contact me even if they are not interested in the listing where they saw the sign.

It’s always been a pleasure to set up a Listing Domains site, as I have learned to expect virtually instant support from your customer service team. My requests for customization have been handled quickly and the communication has been clear, allowing me to create the “look” that I want almost instantly and effortlessly.

Thanks again for your professional support, and I look forward to using Listing Domains for my next listing.”

-Debbie Schiraldi, Hudson Heritage Realty

“I have been so happy with my individual websites I purchase thru The site is easy to use, competitively priced and the sign riders arrive very quickly. I thought a listing for each website was silly at first, but decided to give it a try. Now I use them for EVERY LISTING. My Sellers really love them, and it helps me stand out from the competition. The reason I am writing today is to tell you I just closed my first sale which was a direct result of my LD website. My listing at 2990 Laurel Street in Napa ( had been on the market 110 days when an out of town couple drove by the sign. They liked the park across the street and they wrote down the website. They went home that night, looked at the website and called me the next day to see it. They fell in love with the house from the photos on the website and when they came to see the house they had a really positive, already familiar with the house attitude. Their agent wrote them up the next week and it closed on 9/20/07. Thanks for a great marketing and selling tool! To be sure in this market I need to use all the tools available to get my listings sold. “

“This week, it saved a transaction that almost died on Roy Low’s Lexington Ave listing in Westwood. The Buyer’s agent had just given birth to her first child and was out of touch with everyone. The deal was in the last stage of negotiation where they were a little bit apart. The Buyer, since they couldn’t get in touch with their agent, went to and contacted Roy to tell him they want to get the transaction done. The transaction is now in attorney review and looks solid! This is a great way to reduce the discussion of commission. This is a success story of using this tool. PLEASE use it!”

The site itself allows for unlimited photos, allowing us to really showcase our listings. The sites are very easy to set up and maintain. Even after the home has sold, we renew the sites so that we can link them to our website on our Solds page.
