What IDX Technologies Work on WordPress?

You can use three main IDX technologies on WordPress: iFrames, RETS, and RESO API. Each has its benefits.

iFrames are an older way to show MLS listings on your site. They’re like a window on your webpage where you can display content. They’re cheap but don’t help your website’s search engine ranking because search engines like Google can’t see what’s in these iFrames.

 Also, Iframes are not very flexible in how they look or work.

RETS is different because it brings the listing data right onto your website. This is great for SEO – search engines can see and use this data, which helps people find your site more easily. However, the extra data might require more web hosting space.

RESO API is a newer technology that connects your website to the MLS with a unique tool called an application programming interface or API. It’s easier to set up and manage than RETS. It’s also flexible – you can choose to store the listing data on your site or use the MLS directly, which could save on hosting costs.”
