Automated bidding is a hot topic in the PPC industry.

Google is continuously improving its machine learning capabilities and expanding the product offering, making it tricky to stay on top of the latest best practice.

As new types of automated bidding emerge, with new goals and smarter optimisation, the landscape becomes more complex to navigate.

The common questions we’re asked by ads managers

1. Does Google’s automated bidding work? I’ve tried it in the past but didn’t have good results

We’ve found that performance of the bidding algorithms has significantly improved over the past six to eight months and when we’ve tested Target CPA and Target ROAS against manual bidding, more often than not the client has seen better results.

2. What bidding strategy should I use for my campaigns?

That depends on your goal and desired results. We’ve got a simple decision tree that will take the stress out of choosing the right bid strategy. Read on to find out more.

3. What IS the bidding algorithm?

That’s above our pay grade. Google keeps the secret sauce under lock and key. All we know is, it is smart, and getting smarter, and it would not be surprising if it became self-aware…..if it hasn’t already *ominous music*

Navigate this evolving landscape with confidence Using our simple, easy-to-follow flowchart

We’ve had the amazing opportunity to spend time with some of Google’s super-smart Product Engineers who have lifted the hood on Google’s best practice for automated bidding implementation.

In developing this flowchart, we’ve taken their insights and combined them with a healthy dose of our own observations, alongside feedback from our wonderful agency partners.

You’ll notice for instance that we don’t currently include all available automated bidding strategies in our flowchart — we think there are still a few tweaks that can be made to some in order to achieve optimal results so we recommend holding off on those if you’re new to automated bidding and testing the waters.

What attribution model should I be using for best results?

We know — attribution models can sometimes be just as murky as automated bidding when it comes to best practice.

Using the right attribution model is just as important to the success of the automated bidding strategy as the bid strategy choice itself. They are dependent and go hand in hand, like vegemite and toast (or peanut butter and jam, for those non-Aussies).

As a general rule of thumb, we recommend using a non-last click attribution model when campaigns are using automated bidding. Which one? Good question. To get the most out of your bidding strategy, we’ve also included our best practice flowchart for choosing an attribution model.
