Tracking which display ads your competitors are running and where they are running them is complicated. For the most part, savvy advertisers today don’t often just run display ads is the way they used to. Advertisers are less likely to run ads on a specific website than they are to run ads to a specific person no matter what website they are one. This super short example is just intended to show that tracking your competitors display ads is hard because scraping that data just isn’t possible because display, retargeting, etc. is more user specific than it is location specific. To add to this, the ad messages are often dynamic based on the user’s behavior (website actions).
On this page, we’ll look at just a few companies trying to provide this data, although we think is less reliable than people thing.
