Showcase IDX

Showcase IDX is the leading real estate search and consumer engagement platform, helping agents, teams and brokers generate leads, improve their websites, and stand out. The Showcase IDX WordPress Plugin gives real estate agents and brokers portal-quality property search that is deeply integrated into WordPress. Indexable, and fully mobile-ready. WHAT OTHERS ARE SAYING “I switched from IDX Broker. I get more voluntary sign ups than I did with old provider. I think that speaks for itself.” “No solution even compares with what Showcase IDX offer. There is no way I would steer clients towards any other solution.” “I have used both Diverse Solutions and IhomeFinder. Neither delivered what I wanted. Since switching to Showcase, my bounce rate is down 20%, time spent on my site has doubled, and most importantly I am getting 4x more registrations on my site.” “No subdomains or Iframes is probably my favorite feature, but at the end of the day it’s about Results. I think the biggest thing is how “sticky” their site becomes. With Showcase IDX, the retention rate is much higher.” “An IDX Feed That’s Above The Rest! Showcase IDX is a better solution in regards to search rankings. I love the hot sheets and the simplicity to create “hot sheets” for different areas.” “Best IDX plugin by far! Showcase IDX is now the only IDX I recommend to my clients. Visually, it is stunning and so much better than the other IDX’s. To top it off, customer service is top notch” “Best IDX Solution out there. No solution even compares with what Showcase IDX offer. There is no way I would steer clients towards any other solution.” “Best WordPress IDX, period. Simple to use (i.e. low bounce rates and high user engagement), great mapping with polygon search, fantastic mobile responsive functionality, ‘login with facebook’, ultra-fast, and they are always adding or updating functionalities.” “Converts website leads at a high level. Showcase IDX is leading the way in the world of WordPress IDX solutions. Clients love utilizing the Showcase IDX product with original features not found in any other product.” “by far the best IDX solution out there. Forward thinking, always improving, with a clear focus on the interface – one of the major areas other providers fail. It feels like everyone else is still playing catch-up all these years later.”

MLSImport

MLSImport connects a WordPress real estate website directly to the MLS. Instead of embedding a third-party IDX iframe, MLSImport retrieves listings through the RESO Web API and saves them in your own WordPress database as native content. The listings live on your own domain, which means faster pages, full control over the content, and real SEO value for each property page. Once a listing is imported, MLSImport keeps it up to date automatically. An hourly sync checks for new and changed listings, while a daily reconciliation removes listings that are no longer available in the feed. This keeps the website aligned with the MLS without requiring manual updates. Photos are served directly from the MLS CDN, so thousands of listing images do not need to be stored on your server. MLSImport works with any WordPress theme. Its Standalone mode provides its own property search, listing cards, half-map search, single property pages, and agent profiles. These can be added using shortcodes, Gutenberg blocks, or Elementor widgets. If you already use a supported real estate theme, MLSImport can also write listings directly into the theme’s own property structure. This includes WPResidence, WPEstate, Houzez, and RealHomes, so imported listings behave like properties added manually through the theme. MLSImport supports any RESO ready MLS. With your API credentials you can connect to hundreds of MLS markets across the United States and Canada through major RESO data providers such as Bridge, Trestle, Spark, MLS Grid, Rapattoni, Centris, and others. You use your own MLS credentials, so access to the data remains under your own MLS agreement. You also control exactly what gets imported. You can filter listings by property type, status, county, city, price, and other available MLS fields, choose how MLS fields are mapped into WordPress, and create multiple import tasks for different sets of listings.
