How social media is reshaping global digital marketing in GenAI era

What was once a virtual realm where individuals traded vacation snaps and life stories, social media has become one of the largest marketing machines of the 21st century. It is no longer about friends connecting; it’s where brands encounter consumers, ideas catch fire, and trends are produced in real time. This revolution has ushered in a new business fact: unless a brand is using social media, it’s not in the game.

As we continue into the second half of this decade, the power of social sites on consumer behaviour is more influential than ever — likes, shares, and comments now influence what people purchase, how they think about brands, and even how businesses craft their marketing campaigns.

The influence of social media on world advertising is undeniable. Across Asia and the Americas, social media advertising is an inevitable entry in marketing budgets. Currently, the United States and China top the list, reporting the highest ad expenditure on these platforms. But this is hardly a regional phenomenon.

Brands on continents are increasingly allocating large shares of their marketing budgets to social media platforms, enticed by visions of high visibility, targeted accuracy, and quantifiable payback. Marketers everywhere are quick to shift strategies to catch people where they increasingly reside — online, scrolling, swiping, and streaming.

TikTok and social media are placed in the top three consumer trends in 2025, a result borne out in global surveys of marketers everywhere. Video content dominates on these platforms, a reality that keeps continuing to drive brands towards such platforms as TikTok, YouTube, and Instagram.

The reasons why video content is so powerful is not only because it can grab attention, but also its adaptability — enabling product demonstration, narrative, influencer partnerships, and more, in an easily consumable package that corresponds with contemporary attention spans.

The supremacy of video is not a new phenomenon, however. Facebook, YouTube, and Instagram, all of which place strong emphasis on video capabilities, have billions of active users and remain central to the way brands engage with audiences.

Facebook and Instagram still provide the best return on investment, say marketers. These Meta-owned ones have been consistently providing strong advertisement tools, advanced audience segmentation, and advanced analytics that brands have faith in.

In 2023, they led the list of platforms providing the highest ROI in social media marketing. Their success highlights an important fact about the world of marketing: new platforms may become trendy, but long-standing players maintain a dominant advantage by virtue of scale, infrastructure, and advertiser comfort.

For Meta, this continued relevance in a rapidly changing environment is both a testament to its adaptability and a reflection of marketers’ desire for predictable performance.

Social media is no longer limited to the business-to-consumer (B2C) realm. LinkedIn has also emerged as an indispensable tool for B2B marketing, talent acquisition, and sector networking.

Indeed, LinkedIn was named the most significant platform for B2B marketers, highlighting that the impact of social media transcends industries and audiences. From software companies targeting CIOs to manufacturing companies selling to distributors, social media has now become integral to how professional connections are made and cultivated.

Outside of business, the presence of social media in daily life is equally significant. An online survey conducted around the third quarter of 2023 revealed that 50 per cent of users accessed social media to keep in touch with friends and family. Almost 40 per cent access it during free time, demonstrating its strong integration into daily lives.

Facebook maintained its position as the most utilised site in 2024, with an estimated 3.07 billion active monthly users. Instagram and YouTube come close behind, each having more than two billion users. The success of these sites is closely linked to the popularity of video material, proving that visual narrative forms the core of the online experience.

Step in generative artificial intelligence — an advancement that has provided social media marketing with a completely new dimension. The union of GenAI and social media is redefining the way content is generated, campaigns are conceived, and strategies are implemented.

In a 2024 worldwide survey of marketing, PR, sales, and customer service professionals, the greatest benefit of GenAI in social media marketing is greater efficiency, named by 38 per cent of respondents. Coming in at a close second was simpler idea generation, stated by 34 per cent. These advantages are especially appealing in a world where the demand to generate large quantities of content inexpensively and quickly is relentless.

But as GenAI presents compelling opportunities, it also poses significant challenges. Authenticity, a highly-prized quality in social media narrative, is compromised. Approximately 43 per cent of the marketers questioned in May 2024 acknowledged that sustaining authenticity was a major issue when applying GenAI to social media marketing.

Close behind, 40 per cent worried about maintaining the value of human imagination. Such concerns are valid. As content produced by AI fills timelines and feeds, it becomes more difficult to distinguish between human-created storytelling and algorithmic imitation — both for audiences and for brands trying to create real connections.

What is arising is a sensitive balancing act. Brands are increasingly tapping GenAI for what it is best at — accelerating ideation, automating drudge work, and allowing personalization at scale. Simultaneously, they are attempting to preserve the human touch that gives voice, tone, and emotional richness to an initiative. This balancing act between automation and authenticity will likely set the next generation of social media marketing in motion, necessitating marketers to be both tech-literate and creatively rooted.

The statistics say it all where this is all going. With four out of five marketers recognising greater exposure as one of the top advantages of social media marketing, it is apparent that these sites are vital for establishing brand exposure.

In the siloed digital world of today, social media provides a single platform where a brand can share its story, receive real-time feedback, and adjust on the fly. It’s nimble, quick to respond, and inexpensive — a marketer’s ideal match.

In the midst of this changing landscape, my own journey into teaching digital marketing has been as enlightening.

A Digital and Social Media Marketing course at Mahatma Gandhi University in Kottayam provided a bird’s-eye view of how the academic world is grooming tomorrow’s digital talent. The energy level among young people was infectious. From learning SEO strategies to knowing the Instagram reels algorithms, students are diving into the skills that underpin today’s digital economy. Notably, GenAI has already entered its curve of learning.

Through interactive lectures and hands-on assignments, they are learning how artificial intelligence can accelerate campaign planning, automate analytics, and even recommend creative direction. The learning space is not only technical — it’s visionary, creative, and highly responsive to the beat of contemporary media.

This educational environment also served to highlight an important realisation: despite the changes in tools and technology, marketing’s fundamental essence is storytelling. The students I learned alongside were not simply being taught to reach audiences; they were being taught to talk to them, to move them, and to impact their decisions.

With the guidance of faculty and the tooling of an innovative curriculum, they are entering the future as fully prepared leaders for the next chapter of digital evolution.

The future of social media marketing will be determined by three concurrent forces: platform evolution, AI innovation, and changing consumer expectations. Platforms will keep on evolving — launching new formats, features, and monetisation models.

AI-based tools will get even more intuitive and intuitively embedded, allowing marketers to do more with less. But consumers, becoming more sceptical about inauthenticity, will also set the bar higher, expecting personalised but authentic interactions.

What doesn’t change is the potency of the medium. Social media is today the marketplace, the billboard, the customer service counter, and the public relations department — all in one. It’s where people converse, reputations are forged, and brands flourish or perish. As it goes in 2025, social media is no longer included in marketing strategy — it is marketing strategy.

And with consumer behaviour and technology both racing ahead in breakneck speed, there is only one true constant — change.
