When global advertising investment rises, a bigger media budget can feel like the natural response. Put the decision in smaller terms. If you had one more dollar to spend tomorrow, would it buy more reach, a better ad, or a smoother path to purchase? The answer depends on where your business is losing sales today.

Visibility is a basic part of running a business. If potential customers rarely hear about you, they have few chances to consider what you sell. Marketing investment helps close that gap. Paid advertising can bring your offer to more people, while local listings, useful content and referrals also take time and resources to build.

What the global numbers measure

Noticias NEO highlighted the rise in worldwide advertising and marketing spend. In its February report, PQ Media estimated that combined spending rose 6.6% to US$1.92 trillion in 2025 and forecast 9.8% growth for 2026. Those figures describe a prior-year estimate and a forecast, respectively. The total covers advertising and a wider set of marketing activities, so it measures more than the cost of buying media.

PQ Media also estimated that spending on digital and alternative media rose 11.4% in 2025. If you market across Latin America, pair that global view with data from the country you serve. For Mexico, the Valor Total Media study from IAB México, AVE and CiM tracks ad investment and the mix of digital and traditional media. It gives you a starting point for local planning, alongside your own sales data and what you know about customers in the market.

Find out where potential customers drop off

Suppose you run a home services business. Paid search sends inquiries to your booking form, but few turn into appointments. Read a sample of the inquiries alongside the follow-up records. Are people asking for services you don’t offer? Are they outside your service area? Are they hearing back after they’ve already hired someone? Your ad dashboard shows how people found you. The booking records tell you what happened next.

If location is the issue, make the service area clear in the ad and on the landing page. If good leads go cold, try shortening the time it takes to respond. If the team books jobs at a healthy margin and has room to take on more work, an increase in media spend makes sense to test. The same cost per inquiry can point to three different investments once you see how the inquiries turn into sales.

Give each part of the budget a job

Separate the spending that supports demand today, the spending that tests future opportunities, and the spending that helps convert the demand you generate. A search campaign that reliably brings in profitable orders belongs in the first group. A new video concept or a pilot in another market belongs in the second. Landing page improvements, creative production and a connection between campaigns and your sales records can belong in the third.

The split depends on what is holding the business back. An online retailer with plenty of visits and a drop-off at checkout might start by showing shipping costs earlier. A retailer with a healthy conversion rate and few new shoppers might test ads that introduce the product to a broader audience. Write down what you expect each investment to accomplish and give it a review date. The team can then discuss the results before moving money to the next idea.

Measure the return on the additional spend

For ecommerce, compare the cost of acquiring a new customer with the contribution margin from their order. Account for discounts, returns and relevant variable costs. For a business that sells through quotes, track qualified inquiries, proposals and closed sales separately. Cheap form fills can turn into expensive customer acquisition if too few people qualify or buy.

Leave time for sales to come through, especially if customers take a while to decide. Record promotions, price changes and inventory issues so you can interpret the results. When you have enough volume, use a comparable group that doesn’t receive the extra advertising. Similar territories can work if there’s limited audience overlap. That helps you estimate how many sales the extra spend generated. For a smaller campaign, treat early results as directional and increase spending in steps.

Make the next budget meeting about a decision

Bring a specific hypothesis to the meeting. A service team might test whether showing an estimated response time in the ad increases the share of inquiries that become bookings. Agree on the budget for the test, the outcome you’ll measure and what would make you continue, change course or stop. Ask the people who handle bookings or fulfill orders what they’re seeing. They can often explain a pattern you’d otherwise have to guess at.

Global spending trends belong in the planning conversation. The next dollar belongs where you can explain what it should improve and check whether it did. Use sales, margin or qualified pipeline to decide what earns the next round of funding.
