Twenty years in paid search - what has stayed true

I have seen Overture give way to Google AdWords. I have watched automation replace manual bidding. I have seen match types consolidated, smart campaigns launched, Performance Max evolve. The pace of change in this industry is genuinely extraordinary. And yet when I think about what has consistently separated accounts that perform from accounts that do not, the list is shorter and more consistent than you might expect.

Business fundamentals always dominate

Twenty years in, I am more convinced than ever that paid search amplifies what is already there in the business - it does not create it. A business with a compelling offer, a clearly defined customer, and a sales process that converts will see paid search transform their growth. A business without these things will find that paid search exposes the gaps rather than filling them. The advertisers who consistently get the best results are those with the strongest underlying businesses.

Data quality is the limiting factor more often than strategy

The best strategy in the world cannot overcome bad conversion tracking. The best bidding strategy cannot perform without accurate signals. Across two decades, data quality problems have consistently been the most common root cause of underperformance I have encountered. More so than poor targeting, more so than bad ad copy, more so than bidding errors. The first question I ask when performance deteriorates is always: is the data right?

The client relationship matters more than the technical execution

The accounts that have performed best over time have been the ones where I had the closest relationship with the client - where information flowed freely, where problems were discussed honestly, where both sides were invested in working through challenges together. Technical excellence matters. But it operates within a relationship context that either enables or constrains what is possible.

Stay curious or become irrelevant

Whatever the current best practice in paid search is, it will change. Match types, automation, attribution, creative formats - all of these have changed dramatically and will continue to change. The practitioners who have thrived through these changes are the ones who stayed curious, adapted quickly, and maintained a mindset of learning rather than defending what they already knew. Twenty years in, the most important professional trait I can identify is still intellectual curiosity. Everything else follows from that.
