How is Big Data Used in Advertising

Big data is changing the face of advertising. With the ability to collect and analyze huge amounts of data, advertisers can now understand their customers better than ever before. They can create highly targeted ads and marketing campaigns that resonate with specific groups. Big data provides invaluable customer insights that can transform a company’s approach to advertising.

What is Big Data?

Big data refers to extremely large data sets that can be analyzed to uncover patterns, trends, and associations. We create 2.5 quintillion bytes of data every single day, according to IBM. Everything from online transactions, social media, GPS signals, and surveillance cameras generates massive amounts of data. Big data comes from a wide variety of sources and generally has the 3Vs:

  • Volume – Size of the data sets.
  • Velocity – Speed at which data is generated and processed.
  • Variety – Different types of structured, semi-structured, and unstructured data.

The huge amounts of data can feel overwhelming. But with the right analytics techniques and tools, all that data can become a goldmine of insights.

As consumers interact more through digital devices, they leave behind trails of data. Smart advertisers leverage big data and analytics to better understand user behavior and create targeted campaigns. Although TV, radio and billboard ads still have their place, data-driven digital advertising allows for more personalization and optimization.

Why is Big Data Important for Advertising?

Big data brings several advantages that can transform advertising strategies:

Precise Targeting

Today’s customers expect personalized communication. Big data enables advertisers to segment audiences and deliver tailored messages to the right people at the right time. Rather than wasting money on broad TV and radio ads, companies can focus ad budgets on high-value customers most likely to convert.

Predictive Analytics

Sophisticated analytics tools can identify trends and patterns to accurately predict customer actions. For example, marketers can pinpoint which factors motivate a purchase or cause customers to abandon their carts. These insights help shape better ad campaigns.


Real-time data allows advertisers to rapidly test variations of ads and analyze performance. Companies can tweak messaging, visuals, placement and other variables to achieve continuous optimization.

Customer Insights

The better you understand your customers, the better you can serve them. Big data analysis reveals customer demographics, location, behavior, preferences, and more. These rich insights inspire creative advertising strategies that align with consumer needs and desires.

Using Big Data for Marketing Research

Big data plays a crucial role in marketing research. Traditionally research relied on surveys, interviews, focus groups, and observational techniques. While these qualitative methods remain useful, big data offers some distinct advantages:

  • Huge sample sizes – Big data draws from the behaviors of millions of people, far more than interviews alone could reach. This massive scope leads to more statistically significant results.
  • Real-time data – New data pours in continuously rather than relying on periodic research projects. This allows more agility to respond to emerging trends.
  • Reduced costs – No need to devote resources towards conducting surveys or interviews from scratch. The data is already there waiting to be analyzed.
  • Reduced biases – People do not always self-report accurately in interviews and surveys. Big data reveals what people actually do as opposed to what they say they do.
  • Cross-channel insights – Collecting data from multiple touchpoints paints a fuller picture of the customer journey across channels. This holistic view leads to stronger insights.

For example, an athletic shoe company could analyze customer website behavior, social media activity, engagement with online ads and past purchases to identify market segments. Interested in running shoes? Spend time reading reviews comparing shoe models but rarely buy? Share running routes and tips through an online community? This cross-channel data helps the marketer create persona profiles and target messaging.

Artificial Intelligence in Advertising

<span style=”text-decoration:underline;”>Artificial intelligence (AI)</span> refers to computers mimicking human intelligence to interpret data, learn, and make decisions. AI now powers many aspects of advertising:

  • Chatbots for customer service – Chatbots rely on natural language processing to understand customer queries and respond appropriately 24/7.
  • Dynamic creative optimization – AI algorithms test different ad variations and automatically serve the best-performing creative.
  • Predictive analytics – Machine learning models can make predictions about consumers based on massive datasets.
  • Hyper-personalization – AI tools help craft customized ads tailored to each individual user.
  • Fraud prevention – AI identifies and blocks bots, suspicious traffic patterns and other fraudulent activities.
  • Marketing automation – AI streamlines repetitive tasks like email campaigns, social media posting, ad management, data analysis, and more.

AI takes big data analytics to the next level. The computational power of machine learning allows marketers to keep improving campaigns and stay ahead of the competition.

Real-World Examples

Let’s look at some real-world examples that demonstrate the power of big data and AI in advertising.


The popular streaming service leverages customer data to serve extremely tailored show recommendations and effectively promote new content. Their famous recommendation algorithm utilizes machine learning to analyze user behavior, including:

  • Viewing history
  • Search and browsing activity
  • Play/pause/rewind actions
  • Ratings
  • Time of day

All this data trains the algorithm to recommend shows that align with personal tastes. For example, if you binged every episode of Stranger Things, the algorithm suggests similar sci-fi and horror titles. The super-specific recommendations keep users engaged.


This music app also relies heavily on data. The more you listen, the better Spotify gets at recommending playlists and artists to match your audio tastes. They analyze listening patterns, liked songs, browsing history, and who a user follows. But they go beyond intrinsic data and factor in the musical tastes of other users with similar behaviors. This collaborative filtering helps surface fresh new music choices.


Amazon’s advertising business has boomed thanks to their wealth of customer insights. When people shop online, Amazon gathers data including:

  • Purchase history
  • Product reviews and ratings
  • Browsing and search keywords
  • Cart activity
  • Demographic info

They leverage these insights to display targeted product recommendations and sponsored ads throughout their platform. Advertisers can create Amazon ads optimized for people who are already interested in their types of products.


Google dominates the online advertising industry in large part due to its data prowess. Insights drawn from Google searches, Maps activity, YouTube viewing patterns, email content, and more lead to better ad targeting. Google’s automated bidding algorithms leverage machine learning to calculate a consumer’s probability of clicking or converting based on historical data. More personalized paid ads help Google attract big ad budgets.

Challenges of Big Data Advertising

While big data unlocks huge opportunities in advertising, it also poses some challenges:

  • Data silos – Data trapped in organizational silos makes it harder to compile and draw connections. Advertisers must develop systems to integrate data across channels and teams.
  • Poor data quality – Just having more data does not necessarily lead to better insights. Ensuring clean, accurate, and relevant data requires strategic data management.
  • Security risks – Gathering expansive customer data raises major privacy concerns. Companies must be ethical and transparent about data practices to maintain trust.
  • Complex algorithms – Machine learning models can be black boxes, making it hard to explain their internal logic. Explainable AI helps make algorithms more interpretable.
  • Talent needs – Data scientists and analytics roles are in high demand. Recruiting and developing these skills within a marketing team is crucial but challenging in a competitive hiring environment.

Despite these hurdles, the advertising potential unleashed by big data far outweighs the growing pains it takes to harness it. With a smart approach marketers can work through the challenges.

In Closing

The days of making broad assumptions about large groups of people are over. Big data delivers the personalized insights needed to connect with consumers as unique individuals. From precise targeting to predictive analytics and AI-enabled automation, data is transforming advertising. Companies not onboard with big data analytics risk falling behind the competition. However, data alone does not lead inevitably to success. Human creativity, empathy and ethics need to steer the application of data for the benefit of both businesses and consumers. With responsible usage, big data can usher in a new era of more relevant, engaging advertising.
