Tools in Microsoft Advertising for creating, editing, and optimizing ad campaigns
Hi Priscilla,
There are three issues here...most critical one is that when you try to change match type for a single keyword or multiple keywords, site doesn't save the changes...so you are stuck with the previous match type and only way around is to delete and re-add keyword with the desired match type. This was tested and confirmed to be an issue by a Bing support person when we were on live chat with them. Besides, "change match types" section always defaulting to "Broad" match type for the selected keyword (even if that keyword could be set as exact or phrase) is a defect. It should show actual match type for the selected keyword. Third issue which is mainly a what-makes-sense functionality is to by default showing match type of each keyword on the keyword list. Google Adwords does that by showing quotes around exact match keywords or brackets around phrase match keywords.
Hope this explains issues better to you.
Thanks.
