Three years of running performance campaigns — the mistakes I still see

I have been running paid campaigns for a while now. Long enough that I have made most of the mistakes myself and then watched others make them after me. What I find interesting is that the mistakes are not random. They cluster around the same few decisions, and the platforms are often designed in ways that make the wrong choice feel like the right one.

The first mistake is optimising for the wrong metric. Google and Meta both have default metrics that look good in reports but do not always mean what clients think they mean. Clicks that do not convert. Impressions that do not matter. "Results" that are not the results your business cares about. The platform wants you to see a number that justifies the spend. Your job is to define what the number should be before the campaign starts, not after.

The budget distribution mistake

I see this constantly: a client has a budget of fifty thousand rupees a month and splits it across eight campaigns. None of them gets enough spend to exit the learning phase. All of them have a thin data set that makes optimisation unreliable. The account looks active but it is actually spinning its wheels.

Better to run fewer campaigns with adequate budget and let the algorithm work properly. This is counterintuitive because it means saying no to some targeting hypotheses you want to test. But a well-funded test beats an underfunded guess every time.

The landing page assumption

Paid media gets most of the optimisation attention and the landing page gets whatever development time was left over. This is backwards. I have seen well-structured campaigns turn mediocre results because the page the traffic landed on was slow, confusing, or did not match the ad's promise. Conversion rate optimisation on the landing page often has a higher return than another round of bid adjustments.

We now budget for landing page work as part of every campaign engagement. If the client cannot or will not improve the page, we tell them their results will be limited accordingly.

The reporting delay problem

Most clients review campaigns on a monthly basis. Monthly reporting cycles encourage monthly thinking, which is too slow for platforms that can shift significantly in a week. We moved most clients to weekly check-ins and a lightweight dashboard they can look at any time. The frequency change alone improved campaign performance because we caught problems earlier.

None of these are complicated. That is the point. The mistakes that cost the most money in paid media are usually simple decisions made badly or not made at all. The platforms do not make it easy to do the right thing. Your job is to do it anyway.
