and sometimes advertisers just forget to log in and end up with bad bids. In fact, advertisers can even calculate their Anchor CPC bids using data from all devices, when the correct way to calculate bids is to use segmented data for each device. This all gets even more confusing when you add in geographic bid modifiers, time-of-week bid modifiers, RLSA bid modifiers (coming soon at the campaign level), and from from September 19, demographic modifiers for Search Network ads. I've written a free script that helps advertisers better
understand how much they're really bidding once all the modifiers are layered, and outliers can be jarring. So all of this got me thinking about how to remove some of that complexity. Here's a method my team and I came up with: set an artificial fixed CPC and use the modifiers fax number list from all three devices to dial in the correct bids for each device. anchor 3 As you can see, the bids for one device are no longer dependent on those of other devices and it is much easier to know how much you are bidding. Unfortunately, since device
modifiers can only be set at the ad group level, this method only works well if you're using single keyword ad groups, so the device modifier ads is also the keyword bid modifier. In the great AdWords structure debate, this is another vote for SKAGs (single keyword ad groups). Geographic Modifiers While there haven't been any changes to how geo bid modifiers work, I got an interesting insight during a recent session on Twitter. Many advertisers have reported adding bid targets to their campaigns to make it easier to set bid adjustments later.
