The References Page: Which Projects to Show and How to Describe Them
On many websites, the references page is a wall of logos or a list of project names. A prospect who wants to check whether the business has already solved their problem finds little there. This guide shows how to do better.
Key takeaways
- The references page is not a shop window but a place to check. The strongest proof sits on the service pages; the references page collects all of it and makes it findable by industry and problem.
- The biggest customers are not the best references; the best-fitting ones are. Kumar, Petersen and Leone (2013) showed that a customer’s reference value does not match their own customer value.
- Every project gets the same short format: customer, starting situation, service, result with a number, a voice, a link to the full case study.
- A good references page covers the questions prospects have, with different voices. Ten similar logos answer only one question.
Why does a business need a references page at all?
Almost every company website has a menu item called “References”. Behind it there is often a row of logos, sometimes a list of project names and years. To the business, this feels complete. For a prospect who wants to know whether someone has already solved a similar problem, the page is almost worthless.
The article Writing case studies recommends showing case studies directly on the service page, next to the offer, and not on a separate references page that hardly anyone opens. That remains correct. The guiding question of this article therefore starts one step earlier: What job does the references page have alongside the service pages, which projects belong on it, and how are they described so that a prospect actually uses them? To answer it, we first clarify the terms and a model from research on references. Then we look at selection, description, structure and the connection to sales.
A wall of logos shows that you have customers. A good references page shows that you have customers like the reader.
Terms: reference, case study, references page
A reference is any piece of proof through which a customer speaks for a provider: a quote, a review, a project report, a conversation. The article Using testimonials and references arranges them on the proof ladder in five steps, from the anonymous quote via the named quote, the review on a third-party platform and the case example with numbers up to the reference call. A case study is the detailed version of step 4.
The references page is the place on the website where all approved references are collected, organized and findable. It has a different job from the service page. The service page shows the one piece of proof that fits the service best. The references page answers the question a thorough prospect asks next: have you done this for businesses like ours, and how often?
References page as a shop window
- Logos of the best-known customers
- Sorted by size or date
- Goal: to impress
- No details on problem and result
- Set up once and rarely maintained
References page as a place to check
- Projects with starting situation and result
- Filterable by industry, size and problem
- Goal: to find one’s own situation
- Every card links to a case study or service page
- Updated after every approved project
The thinking model: reference value and the trust portfolio
Which customers are suitable as references? The obvious answer is: the biggest and best known. Research disagrees. Kumar, Petersen and Leone (2013) analyzed data from a financial services provider and a telecommunications company that sold mainly to small and midsize businesses. They developed a measure of a customer’s business reference value: how strongly their reference had moved new customers to buy and how much these new customers were worth.
Most newly acquired businesses were strongly influenced by references but relied on only a few. The customers with the highest reference value were not the same as those with the highest customer value of their own. Four groups of factors determined reference value: the length of the customer relationship, the size of the referring business, the format of the reference and the fit, meaning how well the reference customer and the prospect matched. The authors themselves point out that the two providers studied sold rather simple services, such as business accounts and phone lines. For projects that need explaining, fit is likely to matter even more, but this study does not prove it.
Fit also shows up in other studies. Boyd, Sese and Tillmanns (2023) found among buyers that purchase intentions depended on the credibility and fit of a reference. Singer and Wilkinson (2026) go one step further and describe a trust portfolio: trust does not come from a single voice but from a mix of voices that are credible in different ways, for example through expertise, personal experience, position or independence. In their model, the value of a portfolio depends on how different the roles are and whether each voice fits the question the reader has at that moment. The model is a theoretical paper on online brand communities and has not been tested on references pages. As an organizing idea, it still fits well.
Two views: quantity or fit?
The first view says that many references are more effective than a few, because they show experience and market standing. The second says that one fitting reference is more effective than ten that do not fit. Both contain some truth. Quantity creates a first impression; fit creates the decision. I therefore consider the right approach to be a references page that shows many projects but organizes them so that every prospect finds the two or three that fit them within one minute.
Which projects belong on the references page?
Selection criteria can be derived from the model. They help when you have to choose from many projects, and they show where references are missing. The most important question is not what you are proud of, but who is contacting you today.
| Criterion | Question to check | Why |
|---|---|---|
| Fit with today’s inquiries | Do prospects come from this industry and with this problem? | Fit is one of the factors behind reference value |
| Length of the relationship | Has the customer worked with you for years or repeatedly? | Long relationships show that the work holds up |
| Checkable result | Is there a number, a deadline or a visible result? | Without a result, only a project name remains |
| Approval | Are name, text and image approved in writing? | No publication without approval |
| Timeliness | Is the project younger than about five years or still typical? | Old projects show how you used to work |
| Variety of voices | Does a managing director, a specialist or a user speak? | A portfolio answers more questions than one voice |
A simple comparison often reveals a gap. Count the inquiries of the last twelve months by industry and put next to them the industries your references come from. The following worked example shows a typical finding.
Worked example with freely chosen numbers. Half of the references come from retail, which brings only 15 percent of inquiries. For manufacturing customers, who make almost half of the inquiries, fitting proof is missing.
In the example, the task is clear: win two or three manufacturing projects as references. Which customers are candidates and how to ask them is described in the article Referral marketing.
How do you describe a reference project? The reference card
On the references page, each project has only a little space. So that prospects can compare projects, each one gets the same short format. I call it the reference card. It is a condensed version of the case study in five scenes from the article Writing case studies and links to it where one exists.
Customer
Name, industry, size, region. For anonymized projects, stated openly, for example “automotive supplier, 120 employees”.
Starting situation
One sentence on the problem in the customer’s words. This is where the reader recognizes themselves, or does not.
Service
What you did, in one sentence. Concrete enough for the reader to imagine the work.
Result
At least one number, deadline or visible change, with a reference value and time frame.
Voice and link
A short quote with name and role, and below it the link to the full case study or the matching service page.
| Element | List entry | Reference card |
|---|---|---|
| Customer | Sample Ltd, 2024 | Sample Ltd, manufacturer of packaging machines, 85 employees, Stuttgart region |
| Starting situation | missing | Spare parts inquiries remained unanswered for nine days on average |
| Service | Process consulting | Inquiry process reorganized, templates for quotes, weekly reporting |
| Result | missing | Response after two days on average, measured over six months |
| Voice | missing | “We now see every week where inquiries get stuck.” Head of customer service |
Worked example
Structuring the page: organize, filter, label honestly
The order of the page determines whether a prospect finds the fitting reference. A simple structure with a few filters that follow prospects’ questions has proven itself.
- One overview sentence at the top. How many projects, since when, in which industries. Only numbers you can back up.
- Filters by industry and problem. Two filters are enough for most businesses. A third by company size pays off if you have very small and very large customers.
- Sort the cards by fit. First the projects from the industries that bring the most inquiries, not the newest or biggest.
- Mix the voices. Managing directors talk about impact and collaboration, specialists about quality, users about everyday work. Reviews from third-party platforms add an independent voice.
- Label anonymized projects openly. Industry, size and result stay concrete. Inventing details for camouflage is not an option.
- A next step at the end. For example, a conversation with a reference customer on request, the top step of the proof ladder.
For search engines, a well-maintained references page has a side effect. Projects with industry, region and problem answer search queries that the service pages alone do not cover. This applies above all when full case studies have pages of their own with their own URL.
How the references page works together with service pages and sales
The references page only works if it is connected to the rest. Every service page shows the one fitting piece of proof and links to the filtered references page, for example “All projects with manufacturing customers”. How service pages with proof are written is described in the article B2B website copy.
The same order is useful for sales. Whoever writes a quote looks for the two projects on the references page that fit the prospect’s situation and attaches them. The article Quotes that win describes where proof should appear in a quote. Whether the page is being used can be checked with a few numbers.
Worked example
These values are not targets from a study, but checkpoints for your own business. More important than any single number is the quarterly comparison: do the references still match the inquiries?
The bigger picture
The references page shows a pattern that applies to every form of proof. A provider does not become credible through the number of its customers, but because a prospect finds someone who was in a similar situation and speaks under their own name. This shifts the work: away from collecting well-known names, toward a targeted search for fitting voices for the customers you want to win.
The limits are clear. The study by Kumar and colleagues is based on two providers with simple services in one country. The trust portfolio by Singer and Wilkinson is a theoretical model, not a measured effect. How many inquiries a better references page brings cannot be derived from them. The direction is documented: fit and variety of voices count for more than quantity and fame.
Conclusion and next steps
We set out to ask job the references page has alongside the service pages, which projects belong on it and how they are described. The answer: the references page is the place where a thorough prospect checks whether the business has customers like them. It should feature the projects that fit today’s inquiries, with different voices and checkable results. Every project is described in the same short format, organized by industry and problem and linked to the case study and service page.
- Count the inquiries of the last twelve months by industry.
- Next to them, count the existing references by industry and mark the biggest gap.
- For every approved project, write a reference card with customer, starting situation, service, result and voice.
- Make the references page filterable by industry and problem and sort it by fit.
- Check that written approval exists for every logo and every name.
- Add a link to the filtered references on every service page.
A references page is good when a prospect leaves it with the feeling that their problem has been solved here before.
Frequently asked questions
What belongs on a references page?
Projects with customer, industry, starting situation, service, result and a customer voice, each with approval. In addition, filters by industry and problem so that prospects quickly find fitting projects, and links to full case studies. A pure wall of logos is not enough.
How many references should I show?
There is no fixed number. A goal per industry makes sense: at least two fitting references for every industry that brings many inquiries. More important than the total is that every prospect quickly finds two or three projects that fit their situation.
May I show customer logos on my website?
Only with the customer’s permission. Keep the approval in writing and remove the logo if the customer asks. For details on trademark and advertising law, you should seek professional advice; this is not legal advice.
References page or references on the service page: which is better?
Each has its own job. The service page shows the one piece of proof that fits the service best, right next to the offer. The references page collects all projects and makes them findable by industry and problem, for prospects who check more thoroughly.
Which customers make good references?
Above all, customers who fit the prospects you want to win today and with whom you have worked for a longer time. Research shows that a customer’s reference value does not match their revenue. A midsize customer from the right industry can be more valuable than a well-known corporation.
