One of the most common questions we get is, “How much should I invest in paid media?” The honest answer is… well, it depends.
There’s no universal number that works for every business. Your budget should always be based on what you’re trying to achieve, where your audience spends their time, and what growth stage your brand is at. Whether you’re running Google Search, Meta ads, LinkedIn or TikTok campaigns, your spend needs to be led by strategy, not guesswork.
Start with your objective
Before you even consider numbers, it’s essential to get super clear on your goal. Are you trying to drive awareness and visibility for your brand, launch a new product, increase conversions, or generate leads?
An innate understanding of your objective(s) will shape and steer everything else, including how much to invest, which platforms to use, and how you measure success.
If your aim is brand awareness, platforms like Meta (Facebook and Instagram) or campaign types like Google’s Demand Gen work well because they’re designed to serve engaging, visual content to a wide audience.
If you’re focusing on performance and direct results, you’ll be better served by intent-led campaigns such as Google Search, Performance Max or Meta campaigns geared towards conversions.
Forecasting first, not guessing budgets
Rather than giving a blanket/vague answer on how much you should spend per platform, we prefer to start with forecasting, because context is everything.
Budgets depend on your industry, target location, competitiveness, and the season you’re launching in. What works for an eCommerce brand during peak retail will look very different to a B2B service in a niche market. That’s why we don’t guess: we forecast.
At Green Ginger, we build forecasts in two ways:
1. Starting with your goal
If you come to us with a clear target, such as a fixed budget, a CPA goal, or a revenue figure to hit, we can reverse-engineer the opportunity. Based on your objectives and the data we have access to, we’ll map out what you could realistically expect to achieve across different platforms. GGD clients love this as it provides targets and benchmarks based on actual data, from day 1, which we evolve in line with performance, market conditions, budget, objectives, etc.
2. Starting with the data
If you’re less sure of the goal but have data to work with (like average order value, website conversion rate, or known search demand), we’ll use that to forecast potential performance. We combine this with platform trend data and competitor benchmarks to give you a realistic view of the investment needed to reach your targets.
Forecasts can be created for individual platforms, like Google Search or Meta, or across multi-channel strategies, where budgets are split based on return potential. We build this into every new client proposal and onboarding process as standard.
We can make most budgets work (within reason), but – being fully honest – smaller budgets can limit how quickly we reach our goals, how many variables we can test, and how confidently we can scale. That’s why forecasting is essential to setting expectations and building a plan that actually delivers.
Timing matters too
It’s not just about how much you spend. When you spend it also matters.
Certain times of year, like Q4, January sales, or seasonal peaks in your industry, can significantly affect campaign performance.
Launching a new service? Competing in a busy marketplace? Those moments call for more spend and stronger creative to stand out.
A good rule of thumb is to plan for a testing phase in quieter periods and scale up when it really counts.
Don’t skip the testing phase
Every paid campaign should include some budget for testing.
That means experimenting with different audience segments, creative approaches, and placements. It’s unlikely you’ll get everything perfect immediately, and that’s okay.
The early stages of a campaign aren’t just about driving conversions; they’re about collecting data and learning what works for your audience(s).
Investing in this phase will provide insight and understanding, as well as the foundation for stronger, more efficient campaigns later.
It’s not just about media spend
Ad spend is one part of the puzzle, but the performance of your campaigns also depends on where you’re sending traffic and how strong your creative is.
A slow-loading landing page or unclear messaging can kill even the best-optimised ads. We often advise clients to invest in improving their website, tightening up their user journey, or developing stronger assets to run alongside paid campaigns.
These investments pay off long term, especially if one of your objectives is to scale.
Metrics should guide your budget
The metrics you’re working towards will influence how much you need to spend and how you measure success.
Some of the most common ones we work with include:
-
CPA (Cost Per Acquisition)
-
ROAS (Return on Ad Spend)
-
CAC (Customer Acquisition Cost)
-
COS (Cost of Sale)
For example, if your target CPA is £20 and you’re working with a £500 budget, you’d aim for around 25 conversions. If that’s not being achieved, it may be a sign that you need to scale your spend, allow more time for optimisation, or adjust your targeting and creative.
We’ve covered the Paid Metrics That Matter in more detail in a previous post.
Stay flexible
Paid media rarely stays still.
Platforms change, costs fluctuate, and your competitors shift their strategy, therefore your budget needs to adapt too. That could mean rebalancing spend across platforms, increasing investment during high-performing periods, or scaling back when things dip.
The key is staying hands-on and data-led, rather than setting a number and hoping it works.
