Step 2 - Add your domain to the list of allowed domains
Now visit your domain embed settings and go to the privacy tab to enter the domains you will be embedding Searchie media into. The format of your domain should start with "https://" followed by your domain. Make sure to save the new list of accepted domains.
In the case that this domain setup causes an error on your site, try other domain formats. Some sites work by using "https://www." or simply "www." followed by your domain. This should fix any 403 errors you were seeing.
NOTE: Google Sites
If you are using Google Sites, you will need to add https://googleusercontent.com as authorized domain in your domain embed settings.
