In ad performance reporting and bid automation, small terms often carry big implications. One of the most misunderstood among them is the difference between a percentage change and a percentage point change.<\/span><\/p>\n

At first glance, they may look interchangeable. But when you’re adjusting placement-level bidding rules\u2014say, reacting to a drop in Top of Search impressions\u2014the distinction becomes critical.<\/span><\/p>\n
