In September, IAB adjusted its 2025 outlook as advertisers reacted to macroeconomic uncertainty. The organization lowered its full-year ad spend projection while still expecting double-digit growth in social media, retail media and CTV. The headline for SMBs was not simply that budgets changed. It was that flexibility became a performance advantage.

Small and medium sized businesses often feel economic uncertainty faster than larger brands. A slower month, tariff-driven cost pressure, hiring challenges or local market softness can force budget decisions quickly. That makes rigid annual media plans risky.

Performance and flexibility can work together

When money gets tighter, the instinct is to cut anything that does not produce immediate leads. That can be necessary, but it can also weaken future demand. The better approach is to classify media by job: demand capture, demand creation, retention, proof and testing. Then budget decisions become strategic instead of reactive.

Brand Fuel Digital CEO/Founder Paul Burns says SMBs should know which campaigns are core and which are experimental before pressure hits. “If every campaign feels equally important, the business has no operating system for budget changes. The goal is to protect what reliably drives revenue while keeping enough testing alive to avoid getting stuck.”

How to plan during uncertainty

• Define core campaigns. Protect the campaigns that consistently generate qualified leads, sales or repeat customers.
• Create a test bucket. Keep a smaller budget for emerging channels, creative experiments and new offers.
• Review monthly, not annually. SMBs need faster feedback loops than large enterprise planning cycles.
• Watch margin, not just revenue. Some campaigns drive sales that are not profitable enough to scale.
• Use owned channels to reduce pressure. Email, organic content, reviews and referral programs can stabilize demand when paid costs rise.

Brand Fuel Digital’s View

IAB’s September update showed that even when forecasts soften, digital media does not stop moving. Social, retail media and CTV remained growth areas because advertisers were still looking for measurable attention and performance.

For SMBs, the lesson is to build a media plan that can breathe. Keep the reliable engine running, test deliberately and make decisions from business outcomes instead of dashboard noise. Flexibility is not a lack of strategy. In 2025, it was part of the strategy.
