AI and Black Friday are reshaping marketing and growth strategies in Brazil in November.

November 2025: From the extended Black Friday to the era of hyper-personalization

Every November, Brazil relives the stage for its biggest battle for attention and conversion: Black Friday transforms from an isolated date into a strategic season, turbocharged by technology and multiplied expectations. This year, the cycle intensifies: the biggest brands anticipate offers, build journeys from the beginning of the month, and resort to artificial intelligence to guarantee personalization and efficiency . It’s no longer about who gives the biggest discount, but rather who connects offer, value, and experience throughout the entire funnel and channels, from WhatsApp to social media, from multichannel remarketing to well-structured after-sales service. The result? Continuous relationship building replaces one-off actions, and the very definition of success is being reinvented – both for brands and for the Brazilian digital ecosystem[1][3].

AI redefines marketing, audience, and performance: what has changed?

The numbers are clear: almost 98% of CMOs in Brazil will increase their use of AI by 2025 , and the strategic use of the technology has already increased ROI in almost all large operations. Predictive models guide everything from offer creation to creative automation and campaign optimization, while social commerce advances, reducing funnel stages – a large part of sales already originates within social networks, where chatbots, payments, and customer success occur without friction[2][4]. Another structural shift is the decline in the weight of traditional search engines: AI algorithms already impact how – and where – content appears, requiring agile replanning of SEO and production strategies. WhatsApp emerges as a retention hub, but only gains traction when machine learning generates personalized and relevant journeys[2][5].

The challenge of efficiency and new opportunities for professionals and brands.

Amid the growth of e-commerce (R$ 224 billion in 2025), Brazilian companies face a dilemma: paid media is becoming increasingly expensive and less efficient , requiring a renewed focus on retention, experience, and branding. Automation and omnichannel integration are not trends, but obligations. The new standard takes brands out of their comfort zone: it is necessary to synchronize messages, personalize offers, and monitor data in real time, in addition to investing in differentiators that go beyond price. In the competitive and saturated scenario, those who master technology and build consistent trust – notably through AI – lead in performance and reputation. For marketing professionals, the challenge and opportunity lie in knowing how to use data and AI to create unique journeys, capture audiences across multiple channels, and sustain brand relevance even outside of peak sales periods.[1][3][5]
