In April, 2013, Google said goodbye to free phone call feature in AdWords ad copy and today it's Bing's turn to do so. The search engine has announced a similar change, which will stop Bing Ads advertisers from putting a phone number in the headline, URL, body copy, or extensions such as Sitelinks.
Like AdWords, they will have to use location or call extensions for the phone number. As of now, the change is effective in the US, UK, Taiwan, and Hong Kong, however, expect a wider roll out in other markets in the near future.
The change will go into effect on new campaigns from February this year. However, any legacy ad with phone number will be allowed to run till June 2015. If in case, you make any edit in the legacy ad in the form of fixing a typo or changing the URL – it is most likely to be disapproved.
So, if you want the old phone number ads to run till June, we will advise not to touch them at all.After Google, It's Bing who Says Goodbye to Phone Numbers in PPC Ads!,
