Selling Key Biscayne Real Estate with The David Siddons Group

Our Digital Marketing

Miami is a global city and buyers often come from out of town, so you don’t want to limit yourself to an agent whose reach is only hyper local; relocating is a big element and foreign buyers are a big factor. This is why we created the relocation campaigns, the annual reports and weekly blogs based on what people are searching for. 98% Of searches start online, so if you don’t have a strong digital footprint you are already behind. The best Miami listing agent is whomever has national and global reach and that is what we have to offer. Anyone can reach local buyers or the neighbors in your condo / street without any specific effort, but it takes someone with the right know-how and a large marketing budget to reach a global audience and to really get a unit sold. Local realtors sell regardless of marketing, but big agents sell because of it. Having said this, our team does work with a Key Biscayne expert (Adriana Montbrun) who works and lives on the island and who has the additional knowledge and network to get this unit sold.

Currently we attract around 25,000 visitors a month to our site and 100 new subscribers every week! This is quite simply one of the most highly trafficked real estate sites in the whole of Miami.

Our fundamental goal is to expose your property to the right audience with the right message. It is about targeting a specific audience such as investors, tax refugees or relocating families with geo-specific campaigns and the right message. As you might know these days most buyers are relocation buyers coming for the high tax states (mostly the northeast) who are looking for good quality properties in Miami’s safest areas. We know how to target these relocation buyers and how to keep them interested as we offer very specific and targeted videos and blogs. I invite you to google important search terms like “Relocating to Miami”, “The Best Miami Condos for Sale”. “The best island communities in Miami” or “The safest areas in Miami”, which is something that most relocation buyers search for before they start looking for specific real estate options. This is how the majority finds us!

Engaging with Potential Buyers

Our unique and rich information has earned us a dominant number 1 spot for almost all Miami real estate related key words in the world’s most used search engines. With our real estate reports, real estate forecasts and relocation guides we capture buyers from all over the globe who trust our opinion and who reach out to us for advice and guidance.  Underpinning the strong digital footprint is the digital expertise when it comes to specific marketing campaigns. Our Funnel Campaigns, Retargeting, effective ranking on Google for long tail key phrases and geo specific adverts (to name a few) are leading large amounts of potential buyers to the site. These potential buyers have to subscribe to our site and they will receive a personal phone call as well as our e-mail blasts. As we get many new subscribers to the website I have a very large database of buyers who are actively looking for high quality homes in a very competitive market. One of the reasons I sell my properties very fast is because I pre-market them to my database and a short list of buyers I have in mind for every new listing I take on.

We have only superlatives to describe how wonderful Cris Buzolin was throughout the process of selling our townhouse in Coral Gables. We were away in the UK while the transaction was taking place and Cris handled everything-from clearing out our house, selling contents when she could, arranging the moving and storage and dealing with some very difficult problems which arose. Always patient and very willing to help in every way, Cris is a consummate professional who really cares about her clients and worked extremely hard to get the price we had asked for and make things for us as easy as she could. Nothing was too much for her to handle.Cris and Marianela (who provided additional very helpful assistance to us during the transaction) are part of the team that David Siddons has assembled.When we decided to sell our property, we contacted David and he established the framework for the transaction and ensured that everything proceeded smoothly and in accordance with our wishes. In sum, David Siddons and his team are extremely competent and professional and we are totally satisfied with the service they provided. To repeat, Cris Buzolin in particular, went way beyond what one would expect from a real estate agent. The David Siddons Group has our highest recommendation!

Fantastic group of people to work with!! David and Adriana were responsive and professional throughout the entire process. We weren't familiar with South Florida so David took us under his wing and did a fabulous job giving us a tour of select neighborhoods in South Florida and shared a great deal of information about each. We fell in love with the Botaniko community in Weston and closed the deal with Adriana. If you are buying/selling this is the team you want to work with!! Thank you guys for helping us find our dream home.
