What are ad variations in Google Ads?

Short answer
Ad variations are a Google Ads tool that, in Google's words, allow you to easily create and test variations of your ads across multiple campaigns or your entire account. Google's example is testing how well your ads perform if you were to change your call to action from 'Buy now' to 'Buy today'.
Google says you select the scope of variation (your entire account, a specific campaign or a custom scope), select responsive search ad as your ad type, create the variation, and set details such as the end date and percent of traffic to show the modified ads. You can then view the overall results, drill in to compare modified ads with original ads, and apply the modified ads to your campaign.
Google draws the line with experiments this way: ad variations are best used when you want to test one change across multiple campaigns or your entire account, while custom experiments are best to test multiple simultaneous changes on a smaller scale.
Our reading, not Google's: for a small account the scope is the point. One change tested across every campaign that carries it collects impressions and clicks from all of them, which a single ad group on its own may take months to gather.

Riibon watches every campaign daily and holds a baseline for each metric, so a move in impression share or Quality Score is judged against what is normal for that account, not against a rule of thumb, before anyone acts on it.
Ask the Riibon app whether your campaigns are losing to budget or to rank. It is free, with no time limit and no card. Or book a call and we run it for you.
