Due to many constraints and hidden costs associated with manual bidding, marketers are shifting towards AI for more profitable and productive campaigning. The latest AI technologies, like Google Smart Bidding and Meta Advantage+, are providing highly optimized ad campaign solutions in real-time scenarios to maximize campaign performance.
Manual bidding mainly depends more on the intuition of the human mind and past data performances, which is less accurate and cannot compete with the speed and accuracy of the latest ad platforms. Manual bidding often fails at auction due to conservative manual ad caps preventing it from entering the auction ground.
Meta AI captures a wide range of audience intent by dynamically moving budgets among Reels, Stories, and Feeds, while a human media buyer can overlook them. The primary limitation with manual bidding is Account Stagnation, where the cost is limited to performing specific activities only.
In this blog, we will discuss why manual bidding is falling flat and how AI is taking over it.
Why It’s Time to Make the Shift From Manual Bidding to AI?
AI can foresee upcoming moves in an active auction, whereas it is nearly impossible for the human mind to make accurate predictions. While setting up a manual bid, you set your bid cap max to say 20$ as per your past experiences, whereas AI uses the algorithm calculation and predicts that another bidder will bid with a maximum cap of 80$, and thus you lose due to the cap limitation.
Rather than brainstorming, marketers should use AI to maximize ROAS. Here’s why AI is overpowering manual bidding.
Real-Time Real Advantage
For manual bidding, bids are adjusted once or twice a day at max, but AI bids can be modified hundreds of times per hour to drive maximum results. It works on real-time occurrences, and with every impression, it calculates the three key elements within a second.
- Estimated Action Rate (EAR): What is the probability of this impression converting into sales?
- Ad Relevance & Quality: How much is the ad campaign relevant to the user?
- Bidding Amount: What is the best price to spend to guarantee a profitable social media return on investment?
Hidden Cost With Manual Bidding
Many marketers think the cost of manual bidding can be controlled, overlooking the fact that it often comes with a drain on the budget. When bid adjustment is done manually, performance varies, and CPAs increase. The bid caps often restrict the campaign from reaching its best users and invite traffic that has a low probability of conversions. The time and effort spent on bid adjustment can be used in other areas of marketing, as it never guarantees success.
Managing Creative For Targetting
When you automate your bidding with AI, your content creative becomes the primary signal to perform the operations. If your content is not creative enough, AI will restrict the budget to save the user experience. Before going to bid live, AI has the power to analyse the content, thus ensuring the bidding engine picks your campaign with the best quality score to get the highest priority in the auction.
Prioritizing Data
Meta AI can perform better than a human when fed with quality data. It is the driving point for Conversions API (CAPI).
You are effectively giving the AI a "map" of your customers when you provide clean server-side data. The AI is in guess mode in the absence of CAPI and might not perform correctly. The AI can place a strong bid using CAPI on a person who is likely to be your highest-LTV (Lifetime Value) customer.
Conclusion
Manual bidding is okay to start during the learning phase for small business start-ups. But, to make your brand ready for the competitive digital world, AI will be the fundamental base to progress with. The hidden cost you are paying with manual bidding is not making the ad campaign compete at its best. Relying on humans’ best intuitions is not at all a good idea, as you can let Meta's AI take complete control to evaluate 10 times as many behavioral signals, which is just impossible for human minds.
The future of the industry belongs to those who successfully blend AI's precision with human-led strategic direction.
