Bing ads strongly recommends to use https protocol

Ensuring customer privacy is crucial to your business and ours. To safeguard your customers’ information and guarantee them your website is protected when they see your ad, Bing Ads strongly recommends you update your URLs to utilize the HTTPS protocol instead of HTTP. Due to the security and performance advantages associated with its benefit, HTTPS has become the new standard protocol used on the web. The web browser Google Chrome will begin marking all Opens in new window HTTP pages as “Not secure.” Thus, if your website is still an HTTP URL rather than HTTP, Chrome users who click on your ads will see your URL marked as “Not secure” in the address bar.

How can you check if your site supports HTTPS?

Open your website in a Google Chrome or Microsoft Edge browser and find which of the below-given situations apply to you:
• When you see a green lock icon to the left of the URL, it means your website supports HTTPS (for Edge, this lock may be transparent rather than green).
• If the page is not loading, it says your website is not supporting HTTPS.
• In case the lock does not appear, try re-entering your site's URL with “https://” rather than “http://.”

What if your website supports HTTPS?

Modify your Bing Ads final URLs and mobile final URLs to use HTTPs. There are 3 ways to bulk edit ads and keywords.
• The bulk uploads feature "Opens" in a new window within Bing Ads (best for smaller accounts).
