We’ve all been there. You launch a campaign, it survives the learning phase, and suddenly—bingo!—you’re seeing profitable days. The CPA is low, the ROAS is high, and your dopamine is to the roof.
Naturally, you think, “If I’m making money at $100/day, I’ll make double at $200/day.” So, you double the budget.
The next day? The campaign crashes. CPA skyrockets. Performance tanks.
If this sounds familiar, you aren’t alone. Hundreds of profitable campaigns have been ruined from unconscious budget increases. The problem isn’t your ad or your landing page, it’s the bidding strategy you’re using, and specifically, a misunderstanding of Taboola’s “Maximum Conversions” bidding strategy.
The Old Way vs. The New Way
To understand why this happens, we have to look at how Taboola has evolved.
Back in the day (and still today, if you choose it), we had Enhanced CPC (aka Smart Bids). This was the rugged off-road vehicle of bidding strategies. Once an Enhanced CPC campaign exited the learning phase, you could be really aggressive. We’re talking about scaling budgets by 30%, 50%, or even 100% overnight without really hurting your CPA.
But in August 2024, Taboola introduced a brand new bidding strategy: Maximum Conversions.
The “Max Conversions” Trap
Max Conversions is great on paper. It removes the need to manually bid on sites, making it perfect for media buyers transitioning from social ads (Meta/TikTok) who are used to the algorithm doing the heavy lifting.
But there is a catch: It is incredibly sensitive to budget changes.
Unlike Enhanced CPC, the Max Conversions algorithm cannot handle budget shocks. If you change the budget by more than 30% in a single go, you break the learnings. It doesn’t matter how seasoned your pixel is; a drastic budget increase forces the algorithm to scramble, leading to a spike in acquisition costs.
The New Rules of Thumb for Scaling
So, how do you scale without killing your golden goose? It depends entirely on your bidding strategy. Here is the playbook:
1. If you are using Enhanced CPC:
You can afford to be aggressive.
- Wait for the campaign to exit the learning phase.
- Scale: You can increase budgets by 30% to 100% every other day (or every day if you dare) as long as it remains profitable.
2. If you are using Maximum Conversions:
You must be gentle.
- Wait for the campaign to exit the learning phase.
- Scale: Increase budgets slowly—aim for the 15% to 25% range (absolute max 30%).
- Frequency: Do this only 2 or 3 times a week. Do not touch it daily.
Automating the Discipline
The hardest part of this isn’t understanding the rule; it’s actually following it and consistency. When you are managing tens or hundreds of campaigns, remembering the budget of which campaign you scaled yesterday, and which earlier today doesn’t really work. Plus calculating the exact 15%-20% budget increase for each is logistically slow. Not to mention potential mistakes.
This is where automation comes in. Use TheOptimizer to handle these budget changes for you. By setting rules that automatically scale budgets by the correct percentage based on the strategy, you remove the temptation to “yolo” a budget increase and accidentally ruin your best performing campaign.
Bottom line: If you are using Max Conversions, patience pays. Scale slow, scale steady, and respect the algorithm’s sensitivity.
