Realtyna Property Listing (RPL) via its Joomla MLS Module Add-on can synchronize your website with your MLS Provider database. This is including importing and displaying all or part of your MLS properties on your website with total Search Engine Value. That's because:

1- The properties are a part of your website (not by iframe)

2- All the propery urls are SEF based.

You can see the details of  MLS IDX Integration here .
