Q4: A golden quarter if you know the rules

Google Trends show that interest in “Black Friday” and the Belgian holiday “Sinterklaas” picks up clearly in mid-September. Searches for “Christmas present” heat up in October. Use this window to grab attention. Drive awareness with inspiration posts, wishlist campaigns, and lead generation.

In 2024, 58% of all Belgian online purchases happened on mobile. Expect that share to climb as mobile experiences get smoother. So, focus on mobile users in campaigns, web experience, content, and checkout. Make sure you nail your mobile navigation, load times, intuitive payment flows, and numerous payment options (of which Bancontact is a no-brainer). Test on different devices and browsers to optimize UX, remove friction and reduce drop-off.

Social commerce lets consumers discover new products via social media and shop right from social posts. It’s not optional anymore. It’s a must in your marketing mix. Data from Landmark Global (bpost) shows that social commerce accounts for 10 to 12% of total e-commerce revenue in Belgium. And it’s only going up: nearly 10% annual growth is projected through 2030.

In short: platforms such as TikTok, Instagram Shopping and livestream formats are key in your marketing plan. Both inspiration and purchase happen there. Invest in content that engages and converts: influencer livestreams, shoppable posts, and short videos generate traffic and conversion. Treat social media as part of your sales funnel, not as a channel by itself. With a social campaign without direct shopping integration, you miss conversion opportunities.

According to Think with Google’s "Marketing in the Messy Middle", consumers search more for value and reassurance during economic uncertainty. They scrutinize, compare, and expect brands to prove trustworthiness, even during promotions.

Price matters, sure. But loyalty is earned with relevance, not stunts. Strengthen emotional connection and combine promotions with relevant brand moments. Work with bundles or exclusive deals and add value: create a sense of ‘premium deals’ instead of just a discount. Think limited editions or smart trade-ins that help users. This strengthens trust during the ‘messy middle’: brand presence, behavioural principles, and social proof convince shoppers when they are comparing prices.

Sustainability isn’t a trend. It’s a growth engine. The Belgian recommerce market – refurbished, secondhand and trade-ins – grows 14% annually. And it’s here to stay: expect 11.7% CAGR growth through 2029. Stand out by integrating recommerce offers in your autumn campaigns, such as refurbished products and secondhand actions. This strategy appeals to consumers who care about sustainability.

Bottom line: Q4 2025 is about more than flash sales. Start early, go mobile-first, embrace social commerce, optimise your media and make sustainability part of your story. And above all: use compound creativity, where brand strategy, data, ideas, and media work in perfect harmony. Nail this, and you crush Q4 and set your brand up for success in 2026.
