Bing Webmaster Tools Does Not Distinguish Between http and https

"From a Bing Webmaster Tools perspective, we don't distinguish between http and https, so they effectively appear as the same property to customers regardless of what's imported."

"I agree that setups where there are different content for http and https are super rare (and generally problematic). From a Bing Webmaster Tools perspective, we don't distinguish between http and https, so they effectively appear as the same property to customers regardless of what's imported."

"We typically expect https (given where the web has moved), but if that data isn't available, we should fall back to http or other ports."

Bing Webmaster Tools does not distinguish between http and https, so both effectively appear as the same property to customers. This differs from Google Search Console, which allows separate properties for each protocol variation. When importing Google Search Console properties into Bing Webmaster Tools, the protocol difference may not be preserved. The expectation is typically to use https because most of the web has moved to it. If https data is not available, Bing Webmaster Tools should fall back to http or other ports. Setups with different content on http versus https are described as rare and generally problematic.
