Is your brand wasting ad spend?

Three words no brand or marketeer wants to hear. Wasted ad spend. In short, this means money spent on advertising isn’t bringing enough profit or achieving its goals. At Serotonin, we know just how costly this can be. Here are a few ways you can avoid it and make your spending go further. 

But first, what’s a common misconception in marketing?

Last-click wins. Meta, Google, TikTok, they all love to take credit for sales. But they don’t make it, they simply claim it. We’ve tracked attribution journeys over 300 days across multiple ads, channels, and touchpoints. Yet reports still reward the last click. The result? Wasted budget on campaigns that look great, but don’t deliver real results. 

How can you stop wasting ad spend?

Track ad spend

Tracking and monitoring ad performance is one of the best ways to stop wasted spend. You can do this by setting up robust tracking mechanisms and tools. These provide you with crucial insights into key metrics, like impressions and clicks. You gain a clearer picture of how your ads are performing (or underperforming), so you can find new ways to improve them.

Refine keyword targeting

Review and optimise your audience targeting parameters to make your ads reach the right people. You could even tailor your messaging and ad creative to resonate with your target audience, boosting engagement and conversion rates.

Leverage data and analytics

Getting data-driven insights is also an effective way of removing wasted ad spend. Monitor and analyse campaign performance by leveraging data and analytics tools to gain deeper insights. 

Why not carry out A/B testing? That way you can compare different strategies and optimise your ad campaigns using real-time results.

Don’t believe us? Believe the results

Only last month, we saved a well-known brand €37,000 in wasted ad spend. Then we took things even further by reallocating it across other campaigns. Turning €37,000 into €100,000+ in revenue. It’s not magic. It’s technology, process, and accountability.

So we want to make things easier for your brand to spot any potential leaks. That’s why we’ve created a Wasted Ad Spend Calculator. In just 60 seconds, you’ll see exactly where your budget is going to waste. Stop throwing money at ads. Start making every click count.
