Conversion maximization now also helps in Search

22. June 2026

Let Sklik handle bid optimization for you. The automated bidding strategy will bid on your behalf. Until now, you could use it in the Display Network and in the recently launched Smart campaign. It is now also available for Search campaigns. How can it help you, and what should you watch out for?

Conversion maximization for Shopping Ads and Display campaigns has been available since last summer, and hundreds of advertisers have already tried it successfully. We are pleased that you can now use automation for Search campaigns too – something many of you have been asking for.

How does Conversion maximization work?

The automated strategy sets the cost per click (CPC) automatically to deliver as many conversions as possible while staying within the maximum cost per action (max. CPA) you set. Thanks to dozens of signals, it can respond in real time in each individual auction. You can read more about Conversion maximization in Sklik Help.

In Search, it works the same way as it does for Display Network campaigns.

What is good to know?

As in the Display Network, Conversion maximization monitors max. CPA at the ad group level. Search ad groups are often split into several smaller groups, so each of them works with a smaller amount of data and that data is essential for the strategy to work correctly. What does that mean in practice?

  • Ad groups with a low amount of data may appear to exceed the maximum CPA when you look at the period you use to evaluate campaign performance, typically the last 30 days. Low, or even zero, conversions are not statistically significant data, so that CPA value does not say anything meaningful about how Conversion maximization is performing.
  • The same applies to CPA at the campaign level. If a campaign contains a larger number of ad groups with a low number of conversions, the campaign-level CPA may look exceeded even if the campaign as a whole has enough conversions.
  • Ad groups with a low number of conversions are still in the learning phase. This means they are shown more often so they can collect statistics. As a result, the CPA you see in the interface may be even more likely to look exceeded.

What should you do?

For campaigns where CPA appears to be exceeded, check whether this number is affected by ad groups with a low number of conversions. You should evaluate only ad groups with enough data. A conversion-volume filter can help with this. Ad groups with a low number of conversions are also marked in the interface.

We hope automation for Search campaigns makes your work easier.
