24761 Chap.2 Secondary Data Sources and the Marketing Mix
Secondary Data Sources and the Marketing Mix
Borrowed evidence
Week 2 treats secondary data as information that already existed before your question, gathered by another person or organisation for a different reason.
It is usually the first stop in marketing research because it is cheaper and quicker than collecting your own, and it can be numbers, text, images or documents.
Inside and outside the firm
Internal sources such as till sales, loyalty records and website analytics belong to the company.
External sources come from government statistics, industry reports, customer reviews, social platforms, search trend tools, journals and the trade press, each with its own blind spots.
A dataset can also change status: transaction records logged for billing become secondary data when an analyst reuses them to study buying habits.
Sources follow decisions
The chapter maps sources against the four elements of the marketing mix and five marketing domains, using an invented bookshop chain weighing click-and-collect, and it shows how to justify a shortlist and record what every source cannot tell you.
The same habits carry straight into the sources section of the first report.

Worked example · free
Match seven bookshop sources to the questions in a click-and-collect decision
- 1Is there demand: order-history exports show how often customers already order ahead, gift-card redemptions show gift buyers who know what they want, and reader forum threads show readers asking for easier pickup.
- 1Which branch: council foot-traffic counts show where people pass by, and staff stock-out notes show which branches most often send customers away empty-handed.
- 1When to launch: the publisher release calendar marks the big release weeks, and the book-trade magazine reports how other booksellers time new services.
- 1Unanswered: none of the seven shows whether this chain's own customers would actually use the service or pay a fee for it, which calls for primary research.

Secondary Data Sources and the Marketing Mix FAQ
What counts as secondary data in marketing research?
Any evidence that already existed before your project, collected by someone else or by the business for another reason. Census tables, industry reports, competitor websites, customer reviews and a firm's own sales records all qualify once they are reused for a new question. Because it is cheaper and faster than fresh research, it is usually where an analyst starts.
What is the difference between internal and external secondary data?
Internal data comes from inside the organisation, such as sales records, CRM and loyalty data, website analytics and call-centre notes, and only the company can see it. External data is produced by government bodies, research firms, customers, journalists or academics, and it shows the market beyond the business. A strong source list usually draws on both.
Is Google Trends a reliable source for a marketing report?
It is useful for spotting rising or falling interest in a topic by place and time, sometimes before the change appears in sales. It cannot tell you who searched, why, or whether they bought anything,. Use it alongside sources that show behaviour, and state those limits when you cite it.
Can I cite trade press and news articles in the report?
Yes, as professional sources that offer timely analysis and expert commentary on markets, brands and launches. They are not peer reviewed, so present them as commentary and support any important claim with stronger evidence such as industry data or a journal article. Checking them with the CRAAP test in Chapter 3 shows the reader you weighed them.
Where do UTS students get industry reports and journal articles?
The subject directs students to the UTS Library, which gives access to IBISWorld industry reports through a UTS login and to journal databases. The complementary materials also list the highest-ranked marketing journals on the ABDC list, where A* marks the strongest titles and A marks highly regarded ones.
Assessment move
Practise on a brand you are not assessed on, such as a local hair salon or gym. Choose one decision it might face and write three questions that decision depends on. Under each question, note which family of secondary source could help, government, industry, company, customer-generated, search trends or academic, and one thing that family could never tell you.
Then check the spread: a decision supported only by the business’s own records, or only by outside sources, is lopsided. Repeat the routine for a second decision tied to a different element of the marketing mix. Once the habit is automatic, apply the same question-first approach when you plan the sources section of your own report.
