Performance marketer, moving into Marketing Executive.

I judge a campaign on the conversions that turn into revenue, not on clicks. Ten Google Ads accounts in four months, and one campaign where auditing the conversion data mattered more than optimising the bids.

Case study · B2B wholesale

The report said 288 conversions. Only 100 of them were real.

65% of recorded conversions were junk

Each dot is one conversion the account recorded.

188 retail enquiries, wrong numbers or duplicates100 real wholesale leads
Source: hand audit of all 288 recorded conversions, one row each.

That was the first campaign I ran end to end, and going through every one of those records by hand taught me more than any course had. The platform is measuring what you told it to measure. If you set that up carelessly, it will report success at exactly the moment the business is wasting money.

So I start from the other end now: define what a valuable action actually is, build the tracking that captures it, and only then decide where the budget goes.

AI without direction is just noise

A Good AI Learner Has a Clear Mindset. As Matt Pocock pointed out, the people who succeed with AI aren't the ones who outsource everything to it, nor are they the ones who refuse to use it

AI WITHOUT DIRECTION IS JUST NOISE’, the Claude AI logo, and an upward-trending bar chart icon, illustrating how using AI without clear direction only creates noise.

    Auditing conversion records to separate real leads from noise, then feeding what the junk has in common back into keywords, negatives and forms.

  3. Performance marketing

    Building and optimising Google Ads campaigns end to end: account structure, keyword and negative strategy, and budget decisions tied to qualified leads rather than volume.
