On March 25, Microsoft Advertising announced that they will start letting users see ad suggestions with auto-reply.
These ad suggestions are variations of existing ads you’ve already created, all based on landing pages, keywords, targeting, ad extensions, as well as other content. These ad suggestions will be generated when Microsoft Advertising things that an a group might be better served with more quality ads. There is a limit to how many of these suggestions will be given to advertisers. They will be given a total of 50 suggestions per account.
One more bit of information – ad suggestions marked as auto-apply will begin to serve after 14 days if there aren’t any other actions being taken.
