1. Not setting goals

The first marketing budget issue companies face is a lack of direction. This problem comes from a lack of goal setting when creating your budget. If you have nothing to aim for, you won’t know how to invest and monitor your budget.

And, without any goals, you won’t be able to see the progress you’ve made through your digital marketing investments, making ROI tracking nearly impossible.

How to avoid this marketing budget mistake:

• Set SMART goals for your marketing budget
• Track your goals along with other marketing metrics
• Create varying objectives that all contribute to larger goals

2. Ignoring trends in your industry

Not looking to your industry for trends is a key marketing budget issue. Every industry prioritizes different marketing channels, strategies, and tactics. If you aren’t investing in these strategies, you’ll likely fall behind competitors.

How to avoid this marketing budget mistake:

• Perform competitor analyses for industry leaders
• Research your industry’s preferred marketing strategies
• Look at top-ranking websites and results for industry terms

3. Targeting the wrong audience

If you don’t know who you are marketing to, your budget will go to waste. Many companies don’t take the time to investigate the details of their target audience before selecting the channels they think will work.

You might be surprised at what marketing channels drive the most revenue, which is why it’s crucial to learn as much as possible about your audience.

How to avoid this marketing budget mistake:

• Spend time researching your target audience
• Segment your audience based on their demographics and create buyer personas
• Outline the different steps in your sales funnel and where your customers align

4. Miscalculating your budget

This marketing budget is a simple error caused by calculating your budget incorrectly. For example, if you plan your marketing budget before considering the cost of digital marketing services, you might miscalculate how much you’ll spend per month.

How to avoid this marketing budget mistake:

• Check your work with any formulas you use
• Compile information about digital marketing prices
• Use a recommended marketing budget calculator

5. Lacking data

Data is everything when it comes to creating your marketing budget. If you don’t have a clear look at your customer preferences, leads, conversions, and more, you won’t be able to invest in the right channels. Your data collection methods should give you clear, accurate data about your marketing.

And if you aren’t gathering customer data, start there!

How to avoid this marketing budget mistake:

• Test your data collection tools
• Upgrade any out-of-date or ineffective software
• Invest in quality customer relationship management (CRM) tools

6. Only using one marketing channel

Diversifying your marketing approach gives you the best chance at success and growing your ROI. While it can be easy to play it safe, it’s better to invest in more channels (even if it’s a low investment) to see what works best for your company.

How to avoid this marketing budget mistake:

• Evaluate your marketing approach
• Look at the marketing channels that other companies in your market use
• Diversify your advertising spend into different channels

7. Information and data silos

Another marketing budget error involves information and data silos. If your marketing and sales teams don’t communicate effectively, it could lead to confusion and ineffective marketing spending.

For example, if the sales team sees high engagement from pay-per-click (PPC) ads, the right move might be to invest more in that channel. But if the marketing team doesn’t have the data for those ads, they might not know how effective they are.

Creating better alignment between sales and marketing teams is crucial for your budget’s effectiveness.

How to avoid this marketing budget mistake:

• Combine your sales and marketing data in one place through a CRM
• Create open communication channels between sales and marketing teams
• Testing sales and marketing funnels and comparing their results

8. Only focusing on new customers

While it’s important to earn new customers, it’s also essential to market to past and current ones. Your customer acquisition cost (CAC) might be higher than the amount it takes to maintain customers, especially depending on your industry.

Targeting existing customers with your marketing budget is essential for maximizing your investment and avoiding those high CACs. If you don’t prioritize strategies that either lower your CAC or improve customer lifetime value (CLV), you’re missing out on potential revenue.

How to avoid this marketing budget mistake:

• Create specific retargeting strategies for existing customers
• Reach out to past customers and ask for feedback
• Allocate a portion of your budget strictly for retargeting

9. Underinvesting in marketing strategies

While you don’t want to overinvest in marketing if you don’t have the funds, you also shouldn’t underinvest in strategies. Especially if those strategies have proven useful in the past.

One example of this marketing budget error would be not investing in digital marketing at all or trying to do it all in-house without the proper resources. By underinvesting, you get poor results that don’t reflect your strategy’s potential.

How to avoid this marketing budget mistake:

• Do research about the cost of digital marketing before setting your budget
• Analyze what strategies are bringing in the most revenue for your business

10. Poor forecasting and visibility

If your organization doesn’t have the right data to plan accurately, you might end up in a bind regarding your budget. You must have an accurate view of your budget for the year to prevent overspending and underspending.

For example, if you underestimate the cost of marketing tools and software, you might overspend in the first quarter, meaning you don’t have enough budget for the rest of the year.

Thinking ahead and being realistic about spending can help you prevent this common marketing budget issue.

How to avoid this marketing budget mistake:

• Create marketing budget reports to share across your organization
• Outline the costs associated with marketing for decision makers

11. Neglecting reporting and analytics

Finally, the last major marketing budget error is neglecting your reporting and analytics. Some companies don’t test their digital marketing strategies at all, while others don’t do it often enough. Without checking on your digital marketing approach, you could be missing out on data that could help you allocate your budget effectively.

How to avoid this marketing budget mistake:

• Account for marketing tools and ROI tracking software in your budget
• Take time to analyze the data on a set schedule and compare it to your goals
