Thanks for the information! I have always received conflicting information from the Google AdWords reps regarding running multiple ad extensions at a time. How does Google decide what to display if you have sitelink ads, product extensions, and call extensions all running on the same campaign? It doesn’t appear that more than one extension can be displayed at one time. Is there a disadvantage to running multiple extensions in a single campaign?
This is a great question and may explain why certain campaigns that have one ad extension set up wouldn’t see another that they’ve also enabled. The AdWords help forum isn’t much … well, help on the subject, and there doesn’t seem to be any official documentation, but Kim Clinkunbroomer had a good run down of what trumps what where Ad Extensions are concerned:
Offer Ads (Desktop)
Video Plus box
Contact Forms Extensions
One line Ads Site links
And my Google rep confirmed that certain ad extensions do take precedence:
…some ad extensions do take priority over others; while we enable ad
extensions to help the ad, we try to make sure it doesn’t become too
…product extensions will negate one-line sitelinks (but
not two-line). Most of the trumping that occurs often occurs with product
extensions. Two-line sitelinks are enabled for higher quality scores
(which you may have noticed).
Unfortunately, there are no external guidelines on this, but it varies
largely by whether or not product extensions are there and also on device;
for obvious reasons, mobile extensions are a bit more stringent with
So it looks like there are likely a few variables that determine which ad extension shows for your ad, but given that the prioritization is outside your control it’s likely best to enable whichever of the ad extensions both make sense for and are eligible for your account and monitor their progress.
