So you're thinking about using Squarespace for your real estate website and property listings? You've probably come across some visually appealing real estate websites powered by this website builder. And while they may look great, the question remains: Does Squarespace support IDX integration?

Well, the answer is both yes and no. If mobile responsiveness, indexing with IDX property pages on search engines, and overall search engine optimization are not priorities for you, then yes, Squarespace does support it. However, if these factors are important to you, then the answer is no.

In this article, we'll delve into how I arrived at this somewhat contradictory conclusion. But before we do, let's quickly go over what Squarespace is and what IDX is.

A Short Overview of Squarespace

Squarespace is a software-as-a-service company that provides website builders and hosting services. With Squarespace, users can choose from a variety of pre-made website templates and use a drag-and-drop builder to customize and edit their websites. It started as a blog hosting service in 2004 and has since evolved to offer domain name services, e-commerce tools, and analytics.

Now, let's move on to IDX.

What is IDX?

IDX, or Internet Data Exchange, is a software standard that allows real estate websites to pull property data from multiple listing service databases and display it on their site. This means that real estate professionals don't have to manually update their websites when changes are made on the MLS. The data automatically syncs, making it easier to keep property listings up to date.

Now that we have a basic understanding of Squarespace and IDX, let's discuss some important factors to consider when integrating IDX into your real estate website.

What to Avoid When Integrating IDX

Before blindly integrating IDX functionality into your real estate website, it's crucial to consider the potential impact on search engine optimization (SEO). If your goal is to be locally visible on search engines and generate leads, it's essential to ensure that your IDX property pages are search engine-friendly.

If you already have a significant amount of traffic coming to your website through different marketing methods, having search-engine-friendly IDX property pages may not be a top priority. Visitors can access your property listings from other pages on your website. However, for those who are looking to drive traffic and want their IDX property pages to be indexed by search engines, this becomes a significant concern.

While many IDX integration software solutions now allow search engine crawlers to index IFrames (the method used by many platforms), it doesn't guarantee that the web pages will be well optimized for SEO. Competitors who use alternative solutions without IFrames or have highly optimized IFrames may outrank your website in search results.

To play it safe, it's advisable to avoid using IFrames and explore other options for IDX integration.

How Squarespace Handles IDX Integration

Now, let's dive into how Squarespace handles IDX integration. To include IDX on your Squarespace website, you'll need to add a code block to the desired area of the page. You can then paste the MLS code obtained from IDX services into the code block.

It's important to note that Squarespace doesn't support code customization and won't assist with setup or troubleshooting. They also cannot guarantee full compatibility with their platform. Additionally, customizations can negatively impact the display after future updates, posing issues, especially for mobile responsiveness, which is crucial for search engine rankings.

Based on user comments in the Squarespace forum, it seems that IFrames are indeed used for IDX integration. Squarespace does not explicitly mention on their website that a full integration without IFrames is supported, which suggests that it may not be possible.

Given these limitations, it's worth considering other options if you require a fully SEO-friendly IDX integration for your real estate website.

Why You May Want to Consider Other Options

Considering the limitations discussed above, using Squarespace for your real estate website may not be the best choice if you need a comprehensive SEO-friendly IDX integration. There are alternative options that provide more flexibility and better integration for search engines.

One popular option is to build your real estate website on, a widely-used content management system. On WordPress, you have more control and can choose from various IDX plugins or even customize them to optimize integration. In a previous article, I listed 11 WordPress plugins that don't use IFrames for IDX integration.

Here's a short version of that list:

  • DSIDXPress
  • Optima Express IDX
  • Ultimate IDX
  • IMPress for IDX Broker
  • WPL Real Estate
  • Showcase IDX Real Estate Search
  • ClickSold IDX
  • Diverse Solutions
  • MLS Import
  • Simply RETS
  • Wovax IDX

While it is possible to have a developer create a custom IDX integration for WordPress, using plugins is usually a more cost-effective option.

Bottom Line

In conclusion, Squarespace technically "supports" IDX integration through the use of a code block. However, if mobile responsiveness and overall search engine optimization are important to you, Squarespace may not fully meet your requirements. It's worth considering alternative options, such as building your real estate website on WordPress, to ensure a more SEO-friendly IDX integration.
