Even experienced digital marketers make mistakes. And for small businesses, those missteps can be costly. From poorly targeted ads to generic messaging, it’s easy to waste budget and miss growth opportunities if you’re not careful. That’s why it pays to learn from common errors and make sure your strategy covers the right ground, like refining your audience targeting and using content that actually speaks to your customer.
Building out detailed buyer personas and conducting customer interviews can give you sharper insights into what your audience wants. That’s the foundation for smarter, more effective campaigns. Staying on top of digital marketing trends and best practices is key to avoiding the same pitfalls others fall into.
Below, we walk through the biggest online advertising mistakes and what to do instead, so you can tighten up your campaigns and get better results across every platform.
Most common online advertising mistakes and what to do instead
Not measuring your ROAS
If you simply throw money at your online advertising channels without measuring any meaningful metrics, you’ll have no idea how successful your strategy was. What’s more, unsuccessful strategies will burn a big hole in your budget if you keep repeating the same mistakes over again.
What to do instead
Figure out what works and either drop or improve what doesn’t. A step that a lot of marketers forget is calculating your return-on-ad-spend (ROAS). It all starts with deciding what you need to measure. Identify a key conversion metric for your campaign and work out the value that conversion brings to your business. This is your conversion value.
To calculate ROAS, take your conversion value and divide it by the cost of the campaign. This will help you measure the effectiveness of your advertising campaign. Many marketers focus solely on CPA (cost-per-action) or CPC (cost-per-conversion). While this is useful, it only tells you the cost for that single action and doesn’t give as much insight into how your marketing efforts are directly impacting your revenue.
While ROAS is a better metric, you have to have the right data to properly calculate it. If you’re handling data from several sources, or even multiple ad campaigns, take a look at this handy article about using Camphouse’s data integrations to see how successful your online advertising strategy is.
Targeting everyone
Online advertising can potentially target everyone with a computer or a smartphone, but that doesn’t mean it’s a good idea to do this. You need to keep your target audience narrow and your ad message focused. Thinking about the demographics and intent of your potential customers will give you insights into how to target and engage them.
What to do instead
The better you understand what your users are looking for, the easier it is to show up when it matters. This helps you earn their attention and drive more sales. A smart way to improve your intent targeting is by analyzing your organic search data to uncover the actual queries your audience is using.
Then, identify focus topics to build your content for your advertising too. Don’t forget how valuable your organic marketing can be to making better-targeted ads! This strategy can help you avoid cringe-worthy marketing failures.
Leveraging micro-influencers can result in 60% higher engagement rates compared to mega-influencers, which helps in creating more effective and targeted ads.
Not optimizing your budget
Many marketers fall foul of a couple of budgeting pitfalls. On the one hand, they set their budgets high and when they don’t see the conversions coming in, they throw more money at the problem instead of examining what’s working and what’s not. On the other hand, they spread their budget too thinly across too many channels and fail to gain traction anywhere. The critical missing step is to monitor your spend proactively and optimize as you go if you want to bring in the conversions and get the results you need, all while staying within budget.
What to do instead
Firstly, be tactical about your budget. Make sure you allocate realistic amounts for each segment of your marketing strategy. Of course, this will be different for every company but it’ll also differ by marketing channel as well. According to HubSpot, 59% of social sellers reported an increase in sales through social media this year, highlighting the importance of channel-specific budget optimization.
Secondly, keep track of your spend vs. performance per channel and optimize as you go. For example, if you’re getting more conversions via Facebook ads than Display ads, consider rebalancing your budget to increase your ads spend (and your conversions). If this sounds like too much to keep on top of, you could also use media tracking software (like Camphouse!) to view your budget alongside your actual spend so you can adjust it in real-time.
Forgetting your existing customers
Targeting your existing customers is just as important as acquiring new ones (if not more so). It’s a great way of maintaining a strong customer base, and offering discount codes and coupons is one of the best ways to keep those customer relationship ties strong.
What to do instead
Make sure you’re targeting existing customers in your remarketing. Retargeting can boost ad engagement by up to 400%, making it a powerful tool in your marketing strategy.
Offer promotions to attract repeat visitors who are keen to buy from you again. Remember, offering a promotion doesn’t mean customers won’t pay full price for other goods.
The point is you’ve got them to your website and while they may buy discounted items, other things may catch their attention too. This strategy can improve your online reputation and lead to higher customer retention.
Using a generic buyer journey
Reviewing the user journey is critical. Aim for no more than three clicks between your ad and conversion. Test it yourself; if the process feels slow or clunky, it needs work. If users land on a generic page with no clear message or call to action, most will leave without taking the next step. That means wasted clicks, lost conversions, and money down the drain.
What to do instead
Check your user journey contains the information a potential customer needs at each stage of the buyer journey with as few steps as possible. It should take a maximum of three clicks to convert.
Another huge mistake many make is forgetting the mobile user journey. Whatever you do, don’t forget about mobile users and specifically optimize the journey for them too as more often than not it needs to be different.
It takes time to review user behavior and consider how to improve your sales funnel, so be patient and keep gradually optimizing as you go.
Neglecting mobile optimization
With more consumers using smartphones and tablets to browse and shop online, mobile optimization is no longer optional. Many marketers overlook this critical aspect, leading to a poor user experience and missed conversion opportunities.
What to Do Instead
Ensure your website and digital ads are fully optimized for mobile devices. This includes fast loading times, easy navigation, and mobile-friendly designs. Use responsive design techniques to ensure your content looks great on all screen sizes.
Regularly test your ads and website on various devices to ensure a seamless experience. Optimize your social media posts for mobile viewers to maintain a strong social media presence. With 54% of all website traffic coming from mobile phones, this optimization is critical.
This attention to mobile optimization will enhance your social media platforms, boost organic traffic, and improve your overall digital marketing efforts.
Additionally, consider the behavior of mobile users in your content marketing strategies, ensuring that lead generation forms and buyer journeys are streamlined for mobile use. This approach will help small businesses capture the customer’s attention and provide a smooth user experience across all devices.
