Common Questions
What is the best IDX website for real estate agents?
The best all-in-one IDX platform is Real Geeks ($299/month), which bundles an IDX website with CRM, lead routing, and Facebook ad tools at strong value. For teams wanting premium features, Sierra Interactive offers integrated IDX + CRM with advanced accountability. For WordPress sites, IDX Broker ($59-99/month) provides the most flexibility.
How much does an IDX website cost?
IDX website costs range from $59-$999+/month. WordPress IDX plugins like IDX Broker and Showcase IDX cost $59-149/month. All-in-one platforms like Real Geeks cost $299-599/month. Enterprise platforms like Sierra Interactive are typically $400-500+/month. Additional MLS pass-through fees ($25-100+/month) may apply depending on your market.
What is IDX and why do I need it?
IDX (Internet Data Exchange) allows real estate agents to display MLS listings on their website. It lets buyers search properties, save favorites, and receive listing alerts, keeping them engaged on your site instead of Zillow or Realtor.com. IDX converts anonymous website visitors into registered leads you can follow up with.
Do I need MLS approval for IDX?
Yes. You must apply to your MLS for IDX access, which may require additional fees ($25-100+/month in some markets) and compliance with display rules. Approval timelines vary from days to weeks depending on your MLS. Your IDX provider typically guides you through the approval process.
Should I use an IDX plugin or an all-in-one platform?
Use an IDX plugin (IDX Broker, Showcase IDX) if you want to keep your existing WordPress site and add search functionality with maximum SEO control. Use an all-in-one platform (Real Geeks, Sierra Interactive) if you want website + CRM + lead routing bundled together with less integration complexity.
Will IDX help me generate leads?
IDX is a lead capture tool, not a traffic source. It converts website visitors into leads through registration prompts, saved searches, and listing alerts. You still need to drive traffic via SEO, paid ads, social media, or referrals. IDX works best when paired with a strong marketing strategy and fast lead follow-up.
