Based in Orlando, Florida, and with over 16 years of experience in web-based businesses and performance marketing, Odair Kayser has witnessed — and actively navigated — every major transformation in digital advertising. From the early, highly manual days of Google Ads to today’s AI-driven ecosystem, his career reflects the evolution of performance marketing itself.
Working across international markets, Kayser has built, optimised, and scaled digital campaigns in highly competitive environments, developing a pragmatic view of how artificial intelligence is reshaping advertising strategy rather than replacing it.
From the Early Web to Algorithm-Driven Advertising
Kayser began his career at a time when success in online advertising depended heavily on manual execution. Keywords, bids, match types, and account structure were adjusted daily, and performance relied almost entirely on human decision-making.
According to him, the introduction of machine learning into Google Ads did not simply automate tasks — it redefined the entire logic of the platform.
“The system stopped responding to constant manual control and started responding to clarity,” he explains. “The role of the advertiser changed from operator to strategist.”
What Artificial Intelligence Really Does in Google Ads
Despite the growing presence of automation, Kayser believes AI is still widely misunderstood. While machine learning excels at processing vast amounts of behavioural data and optimising bids in real time, it does not compensate for weak fundamentals.
AI performs best when:
- Conversion tracking is accurate
- User intent is clearly defined
- Funnels are logically structured
- Data inputs are consistent and reliable
“When the foundation is flawed, automation only accelerates inefficiency,” he notes.

A Strategic Shift in the Role of Marketers
With AI handling much of the operational execution, performance marketing has become increasingly strategic. Kayser observes that modern advertisers spend less time adjusting settings and more time designing systems.
This includes:
- Defining meaningful conversion signals
- Structuring scalable user journeys
- Interpreting behavioural data
- Aligning business goals with algorithmic learning
This shift has become especially relevant in mature and competitive markets such as the United Kingdom, where advertising costs are higher and efficiency is critical.
“In markets like the UK, AI is not optional,” Kayser says. “But strategy determines whether automation becomes an advantage or a liability.”
A Global Perspective Built on Experience
Having worked across different countries, industries, and traffic models, Kayser emphasises that AI-driven advertising reduces geographical barriers while increasing the importance of data quality.
Automation allows smaller businesses to compete with larger players, but it also exposes poor planning faster than ever before.
“The system doesn’t react to assumptions,” he explains. “It reacts to data.”
Looking Ahead: The Future of Google Ads
Kayser believes Google Ads will continue moving toward deeper automation, fewer manual controls, and stronger reliance on behavioural and intent-based signals. However, this evolution does not diminish the value of experienced professionals.
On the contrary, those who understand both human behaviour and algorithmic systems will become increasingly important.
“AI didn’t make advertising easier,” he concludes. “It made strategy unavoidable.”
