Anicca Digital used Google's experiments framework to test the Target ROAS bid strategy and found that none of the campaigns were able to get close to their ROAS targets. They also saw a negative impact on campaigns that were not included in the experiments because high cost per click — resulting from the automated bids set in the experiment — caused their competitors to react and bid higher. This pushed the original campaigns further down in the search results, and a downwards spiral effect was observed with automated bidding.

Anicca used Optmyzr's Rule Engine to manage bids to a target ROAS. Instead of putting the tool on full automation, they decided to review all suggested bid changes and manually accept the ones that kept CPC within a reasonable range.

Anicca observed a significant increase in both their ROAS and conversions via the strategy that they used with Optmyzr. Google ROAS bidding was too crude, and Optmyzr allowed them to put minimum and maximum limits on the bid to prevent it from running away and costing too much.
