Marketing vs. Advertising

Marketing encompasses identifying customer needs, creating products that satisfy those, setting the right prices, making products available, and promoting them effectively. The goal is to build lasting customer relationships.

Advertising is a specific part of marketing focused on spreading the word about products, services, or brands through paid channels. It’s designed to inform the audience about what’s being offered, using various media to influence perceptions and encourage purchases.

Comparing the two:

  • Strategies and Tools: Marketing uses market research, branding, and sales strategies, while advertising focuses on creating and placing compelling messages on a range of advertising channels.
  • Objectives: Marketing’s objective is to satisfy customer needs and build lasting relationships, whereas advertising aims to generate interest and encourage buying decisions.
  • Relationship: Marketing builds customer value and relationships, with advertising playing a crucial role in direct communication to the target audience.

Marketing or advertising can be handled in-house or a business may hire an outside agency to run campaigns or the entire marketing functions.

  • Guide: Ad Agencies and Holding Companies: Marketing and advertising agencies are essential for brands, offering expertise and digital tools to run campaigns without internal resources. They assist with key strategies like SEO and social media and tackle industry challenges such as ad blocking, media fragmentation, and privacy concerns.

Marketing and advertising both aim to move a customer from broad awareness to the eventual purchase.

  • Definition: Marketing Funnel: This outlines a customer’s journey from recognizing a need, to evaluating options, making a purchase, and ultimately, becoming loyal and advocating for the product through word of mouth.

According to EMARKETER, several key trends are shaping the marketing and advertising industry:

  • Accelerated Digital Transformation: Marketing has been going digital for years, with search engines and social media capturing more consumer attention and traditional TV shifting to streaming. Advances in artificial intelligence are speeding up the transformation. Generative AI tools promise faster and easier advertising and personalized content, potentially changing consumer engagement with experiences.
  • Major Shifts in Data Practices: Customer distaste for invasive data and targeting practices have led to data regulations and policy changes from major tech companies. Apple’s changes to app-based tracking and email analytics have disrupted marketing practices, and Google’s sunsetting of 3rd-party browser cookies in 2025 will change how marketers target customers on the open web.
  • Customer Demand for Omnichannel, Always-On Strategies: Today’s consumer wants friction-free experiences across physical, digital and mobile platforms. For marketers and advertisers, that means coordinating campaigns across search, social media, and retail media, and integrating experiences through text, longform and shortform video, playable game ads, and more.
  • Ad channel disruption: Google’s digital dominance is being challenged. Amazon has carved out a massive ad business for product search, and other retail media networks are gaining share. Gen Z is turning to platforms like TikTok for search, the creator economy is driving more purchases, Meta and its X rival Threads are hot, and generative AI search experiences are creating opportunities for new search platforms.
  • Streaming’s Ad-supported TV Takeover: As we said in our 2024 trends report, the future of streaming is ad-supported, giving advertisers new options for video advertising. As more consumers opt for ad-supported plans, CPMs for streaming ads are dropping, making the channel more attractive.
  • AI’s Rapid Ascent: The launch of ChatGPT in 2022 triggered an AI race that will transform marketing and advertising. Use cases like chatbots, generative search, and scaled content generation directly affect consumer experiences, while AI-enhanced functions like data analysis, coding, and ad optimization could create efficiencies for professionals. Marketers are balancing the promise with the pitfalls, as issues around accuracy, copyright, and data privacy with AI models still need to be solved.

Categories of Marketing

Some marketing channels have prompted whole categories, each with their own considerations. Here are several guides to help you strategize for each category.

  • Guide: Meta: Originally Facebook, Meta has evolved from a college networking app into a global giant owning platforms like Instagram and WhatsApp. Renamed in 2021 to reflect its focus on VR and AR for the metaverse, Meta’s recent efforts have pivoted towards generative AI.

  • Guide: Netflix: This platform revolutionized TV viewing and is primed to become a major advertising channel.

Understanding marketing and advertising audiences

Marketing and advertising aim to engage people to buy or use products, services or experiences. But not all potential customers are alike. Attributes like location, income, and age inform how marketers approach an audience. That’s especially true for the three generations below.

  • Guide: Gen Alpha: Gen Alpha includes those born in the early 2010s, who still depend on their parents—mostly millennials and older Gen Zers—for purchases. Like Gen Z, Gen Alpha’s preferences significantly influence household buying decisions.
  • Guide: Gen Z: While still mainly comprised of children, Gen Z has a buying power of $360 billion, a figure that is likely increasing as more enter the workforce. The generation has already influenced changes in how media is served.
  • Guide: Millennials: The largest generation is an important demographic. Having had access to the internet throughout their developmental years, they have a unique perspective and are the second-highest spenders by generation.

Modern marketing and advertising, especially digital marketing, rely on a host of tools and platforms. The first step is to think about the entire stack powering your marketing or experiences.

  • Guide: Customer Experience: Today’s consumers expect seamless, personalized experiences, easy conversion, and proactive support. CX is crucial for brands to stand out, build trust, and maintain long-term customer relationships.

Engines need fuel, and in marketing, that fuel is customer data. A strong foundation of data collection and activation can set brands apart. However, heightened privacy concerns from customers are creating new guardrails for data capture. Here are some key resources to explore.

  • Guide: Ad Targeting Measurement and Identity Resolution: Access to consumer data and identity resolution is crucial for effective marketing, allowing precise targeting and tailored campaigns. But tactics are changing as data access evolves.
    • Definition: Ad Blocking: Ad blocking refers to the practice of users removing or modifying advertisements across digital platforms, encompassing desktop, mobile, and connected TV devices.
    • Definition: Customer Data Platforms: CDPs unify customer data and create single customer profiles. They directly collect and store customer information, minimizing third-party involvement and enhancing data security and efficiency.
    • Definition: Data Clean Rooms: As cookie deprecation and stricter privacy regulations approach, marketers are turning to data clean rooms to merge insights while protecting raw data from external exposure.

Artificial intelligence has powered marketing platforms for years, but the rise of large language models and generative AI capabilities has accelerated that integration. Explore these resources to learn how AI is changing the landscape.

  • Guide: IoT and Connected Devices: By 2025, people will spend about 45 minutes daily with Internet of Things (IoT) devices, EMARKETER forecasts. The rise of AI will make them more powerful.
