Danger: Microsoft Content Ads Beta turned on by default
Microsoft recently notified adCenter advertisers by email that the Microsoft Content Ads Beta would be “available” to all advertisers on August 29. By default, your ads will be shown on the existing search campaign and the new content network. To quote the letter:
On August 29, you don’t have to make any changes and your ad groups will automatically expand to hybrid distribution, meaning they will distribute to search and content pages.
We strongly advise advertisers to turn off the content network initially, partly because it is still in beta, but more importantly because content networks typically exhibit very different performance from search ads.
If you received the letter, there is a link to an online form that you can fill out requesting to have the content network turned off. The form must be filled out by August 26.
