Performance Marketing
Your ads are performing. Your ROAS is solid. Click-through rates look healthy. And yet revenue isn't growing the way it should. That is not a performance problem — it's a strategy problem.
Performance marketing is seductive. It delivers numbers — clear, measurable, reportable numbers. ROAS, CPL, CTR, CPA: a dashboard full of metrics that signal progress. And yet revenue doesn't grow.
The problem is not performance marketing itself. The problem is that performance marketing without strategic context becomes a well-designed system fishing in the wrong pond. In 7 out of 10 cases Simon Förstemann encounters, the campaigns are technically fine. The strategy around them is not.
Simon Förstemann is a growth strategist with 14 years of experience, 6 ventures, 2 exits, and a track record of +74% revenue growth in 18 months at flat budget. Below are the 5 most common — and most expensive — performance marketing mistakes he sees.
Key Takeaways
Clicks are cheap to buy. Revenue is not. When your optimisation target is "clicks" or "traffic," the algorithm delivers exactly that — lots of clicks, little revenue. Algorithms give you what you ask for, not what you need.
The fix sounds straightforward: optimise for conversions, for revenue, for customer lifetime value. But that requires clean tracking, a functioning funnel, and sufficient conversion data — and that's precisely what's missing in most small business and SME accounts.
By shifting optimisation goals away from traffic metrics toward conversion value and customer revenue, Simon Förstemann doubled the ROI on ad spend in one project within 6 months. Same budget. Different goal. Different outcome.
ROAS measures the ratio of ad spend to revenue. What it doesn't show is where customers are dropping out of the funnel. A strong ROAS paired with a poor retention rate means you're acquiring customers expensively and losing them quickly. You're running on a treadmill and calling it growth.
Where funnels leak: landing page conversion rates, checkout abandonment, missing follow-up sequences, a weak first-customer experience. These points all sit outside the ad account — which is exactly why they're so rarely fixed by performance marketers alone.
Scaling means: putting more budget into something that works. Not: putting more budget into something that hasn't been proven yet. But that's exactly what happens — budgets increase because campaigns "look good," not because they're profitably scalable.
Before you scale, you need three things: a validated offer (customers buy and come back), a functioning funnel system, and positive unit economics. Scaling without this foundation doesn't multiply profits — it multiplies losses.
Performance marketing is the fastest route to revenue. It is also the most dependent one. Businesses that rely exclusively on paid channels have no defensive moat. When cost-per-click rises — and it always rises — customer acquisition costs rise with it. When a platform changes its rules — and they do — the business model fractures.
Brand is the opposite: it makes you independent of platforms. Customers come to you because they know and trust you, not because you happened to appear in their feed. Performance marketing combined with brand building is the only sustainable combination for long-term SME growth.
The algorithm optimises for what you give it. If you optimise for clicks, it finds cheap clicks. Cheap clicks often come from people who click but never buy — because the offer doesn't fit, because the price is too high, because there's no purchase intent.
Audience precision costs more than broad targeting. But it's cheaper than accumulating clicks from people who will never convert. The maths only works if you're prepared to give up favourable click metrics in exchange for actual customers.

What is performance marketing consulting?
Performance marketing consulting helps businesses deploy paid channels — Google Ads, Meta Ads, and similar platforms — so they measurably contribute to growth goals. It goes beyond campaign optimisation: it ensures that tracking, funnel design, offers, and scaling strategy all work together. Without that alignment, even strong ROAS numbers can coexist with flat or declining revenue.
How much does performance marketing consulting cost?
Performance marketing consulting typically costs between £100 and £280 per hour for project work. Ongoing retainer arrangements range from roughly £2,000 to £8,000 per month depending on ad spend and complexity. Many consultants also charge a percentage fee on managed ad budget, usually 10–20%. The right structure depends on your budget size and how involved you need your consultant to be day-to-day.
When do I need a performance marketing consultant?
You need a performance marketing consultant when your campaign metrics look strong but revenue isn't growing, when you want to scale but don't know which lever to pull, or when you're investing ad budget without understanding which campaigns are actually driving profit. In 7 out of 10 cases Simon Förstemann sees, the issue is strategic — not a platform or budget problem.
ROAS vs. actual growth — which matters more?
ROAS is an efficiency metric. It tells you how much revenue you generate per pound or dollar spent on ads. What it doesn't tell you is whether you're actually growing, whether you're acquiring the right customers, or whether your business model is sustainable. Real growth measures revenue, margin, customer lifetime value, and customer base — not just ad performance.
Can I do performance marketing myself?
The mechanics of performance marketing — setting up campaigns, writing ads, adjusting bids — can be learned. The challenge is strategic: audience selection, funnel logic, scaling decisions, attribution modelling. That's where external expertise makes the difference between a good ROAS and real, sustainable growth for your small business or SME.
Why do good campaign numbers not always lead to growth?
Good campaign numbers reflect ad platform efficiency — clicks delivered cheaply, impressions served to your target audience. They don't reflect funnel conversion, customer retention, or whether the people clicking ever intend to buy. Scaling ad spend before the funnel is validated multiplies losses, not profits. A performance marketing consultant bridges platform metrics and actual business outcomes.
