Neglecting Ad Copy
Your ad copy is more than a catchy phrase. It’s the bridge between your offer and your customer’s needs. Without understanding your audience’s pain points, goals, and motivations, your copy won’t land.
Strong copy resonates, positions your offer as the solution, and nudges people to take action. If you’re seeing clicks but no conversions, revisit your messaging. Need inspiration? Read our guide on ads getting clicks but no sales.
Not Investing in Creative
Creative is the storefront of your campaign. Scroll-stopping visuals and videos are what make people pay attention long enough to read your copy. Skimping on this step is one of the fastest ways to tank results.
High-quality, story-driven creatives aren’t optional, they’re essential. They’re also the foundation of effective A/B testing – without them, you’ll never know what truly works.
Incorrectly Setting Up Data Tracking (or not tracking anything at All
Running ads without tracking is like flying blind. Without accurate data, you can’t measure ROI, optimise campaigns, or even know if your ads are working. Worse, platforms like Meta and Google rely on conversion data to optimise delivery.
Proper setup is non-negotiable. Learn how to measure paid advertising performance so every dollar you spend is backed by real insights.
Neglecting Screen Size
Most people will see your ad on their phone. If your creative isn’t formatted for mobile placements, you’re paying for wasted impressions. Cropped text, awkward layouts, or unreadable visuals kill performance instantly.
Always design for mobile first, then adapt for other placements. Small oversight, big impact.
Setting and Forgetting
TPaid ads aren’t a crockpot — you can’t just “set and forget.” Campaigns need constant optimisation as platforms update, markets shift, and ad fatigue creeps in.
Without monitoring, you risk pouring budget into underperforming ads. Wondering if you should handle this yourself or outsource? Here’s our take on managing ads vs hiring an agency.
Going too niche with your audience
Targeting is powerful, but going ultra-niche can actually hurt you.
Too small an audience = higher costs, limited reach, and missed opportunities. Sometimes, broader targeting lets the algorithm find hidden converters for you. Save niche targeting for retargeting or hyper-specific offers. Speaking of which, see our guide on what retargeting ads really do.
Choosing the right campaign objective
If you want sales, don’t run “traffic” campaigns. Simple as that. Your campaign objective tells the platform what to optimise for. Pick the wrong one, and you’ll get clicks from users who never buy.
Align your objectives with your business goals – conversions for sales, lead gen for enquiries, traffic for awareness. More on how objectives feed into your broader marketing strategy.
Stopping and starting ads
Hitting pause might seem harmless, but it resets the algorithm’s learning phase and kills momentum. Every time you restart, you’re paying extra for the platform to “relearn” how to optimise.
Instead of stop-starting, reduce your budget during quiet times. Consistency wins.
What’s next?
Paid advertising, especially on social media platforms, offers businesses a powerful tool to reach their target audience and drive conversions. However, like any tool, its effectiveness depends on how it’s used. Missteps, no matter how minor they might seem, can lead to wasted ad spend, missed opportunities, and suboptimal results.
