Variables That Impact Consumer Behaviour (And Why Marketers Care)
Consumer behaviour is not random, even if it can seem that way when a campaign craters or soars. In truth, the things people buy, click on and scroll past result from a mix of variables that determine how people think, feel and decide. Knowing these factors is even more crucial in digital marketing and advertising, where a slight change can make a major difference (Kotler & Armstrong, 2020).
One of the biggest influences is psychological variables. Motivation, perception and attitudes all play a role here. Maslow’s Hierarchy of Needs is often referenced in marketing theory, and it still holds up surprisingly well. Needs are motivating forces, which vary according to time and level of development, ranging from basic needs to the need for security, esteem and self-expression (Maslow 1943). Value and reassurance could be the foundation of a budget supermarket; status and aspiration, for a premium tech brand. From my personal experience with digital marketing, even the smallest of tweaks, like a change of word from “cheap” to “great value”, can make a massive difference.
Social variables are just as powerful. Family, friends, influencers and online reviews all shape consumer decisions (Solomon, 2020). Social proof is especially important online. Research shows consumers are far more likely to trust peer reviews than brand messaging, which explains the growth of influencer marketing and user-generated content (Think with Google, 2023).
Then there are personal variables, including age, income, lifestyle and occupation. A student browsing on their phone late at night will behave very differently from a business owner researching software during office hours. This is why segmentation and targeting are essential in digital campaigns (Kotler & Armstrong, 2020).
Finally, cultural factors influence long-term values, humour and preferences. What resonates with one audience may not work for another, making cultural awareness and localisation vital for modern marketers (Solomon, 2020).
Understanding these variables allows marketers to move beyond guesswork and create strategies based on real human behaviour.

I loved reading this blog post on variables that impact consumer behaviour. I liked the detailed explanation on psychological variables and the mention of Maslow’s Hierarchy of Needs. I also think you highlighted social variables very well including trusting peer reviews over brand messaging which I find so true, when it comes to purchasing things myself! I feel a slight expanded explanation on cultural factors and how they affect marketing would be amazing! I thoroughly enjoyed this blog post Freya!
I really enjoyed reading this post and I think it does a great job of clearly explaining the key variables that impact consumer behaviour. I liked how you broke it down into psychological, social, personal and cultural factors, as it made the theory easy to follow and well structured. I feel the link between Maslow’s theory and real marketing examples (like wording changes in campaigns) worked especially well and showed strong application to practice. The references are also really well integrated, which fits the assessment brief nicely. One thing I think could strengthen it even more is adding a short, concrete example of a brand or campaign where these variables clearly influenced outcomes. I also feel a brief concluding line directly linking this back to how marketers can use these insights strategically would round it off well. Overall, this was clear, engaging, and very easy for fellow students to learn from.
Well done Freya, you did a really good job of including lots of theory and addressing every aspect of the topic. The post layout is clear, concise and easy to understand. I loved reading your explanation of Maslow’s Hierarchy of Needs as it was really interesting, especially with the example of how a low-budget supermarket fits into an individual’s needs. To improve, it would have been good to elaborate on your points explaining ‘why’ each factor has an influence on consumer behaviour. For example, why does a student browsing on their phone differ from a business owner researching software? Why are social influences more powerful than others? It would also be great to include an example for cultural factors to help us understand the influence this has on consumers.
Overall it was an informative and interesting read, keep it up!
