A question on Adwords - Discrepancy on mobile and desktop traffic.
What can cause adwords traffic from mobile devices to drop campaign-wide after bid management on just a few keywords in an ad group (same campaign)?
Desktop devices are performing well, but adwords traffic from mobile took a hit. What could be causing this discrepancy between devices? Is there a particular bid sharing requirement that must be followed when performing bid management to ensure mobile devices don't fluctuate or drop below normal levels, compared to desktop devices?
