My Search Results
When adding an IDX widget to your site, set the “Send users to:” option to “my search results“. This option will display the listings on the site rather than in a frame.
If you need to change this in a shortcode, look for
destination="remote"
and change it to
destination="local"
Best Widgets For SEO
The best widgets to use for Search Engine Optimization are the IDX Slideshow, IDX Listing Summary, IDX Listing Details any widget that has the “Send Users To: My Search Result” setting.
These widgets will print the listing info onto the web page. When the search engine crawlers visit these pages they will credit your site with having the listing info directly on the site versus an iframe.
