How to Evaluate an Agency Portfolio and Case Studies
Every agency website has a portfolio, and nearly every portfolio looks impressive. Beautiful screenshots, bold logos and glowing client quotes. But a pretty portfolio does not always mean the agency is right for your business, or that the work actually delivered results.
Learning to read a portfolio critically helps you choose a better partner. Here is what to look for and the questions that reveal what is behind the images.
Look for relevance first
Start by asking whether the agency has done work similar to what you need. Relevance can mean:
- Similar type of project: an ecommerce website, a corporate rebrand, a lead generation campaign
- Similar industry: healthcare, F&B, property, education, manufacturing
- Similar size of business: SMEs face different constraints from large corporations
- Similar audience: for example Malaysian consumers, B2B buyers or regional markets
An agency does not need to have worked in your exact industry, but it should show it can handle your type of challenge. A team that mostly designs luxury brand campaigns may not be the best fit for a practical service business that needs enquiries.
Check that the work is real and live
Portfolios sometimes include concept work, unused pitches or projects that have since changed. That is not necessarily dishonest, but you should know. For websites, visit the live sites. Ask yourself:
- Does the site load quickly on your phone?
- Is it easy to understand and navigate?
- Are contact forms and buttons working?
- Does it still look like the portfolio screenshot?
If the live site looks very different, ask what happened. The client may have changed it after the agency left, which is common, but it is worth understanding.
Tip: look at older projects as well as the newest ones. They show whether the agency's work holds up over time and whether clients stay with them.
Read case studies for results, not adjectives
A strong case study explains the challenge, the approach and the outcome. Weak case studies are full of adjectives like "stunning", "innovative" and "award-winning" without any explanation of what changed for the client.
Look for:
- A clear description of the client's problem or goal
- What the agency actually did, step by step
- Measurable results, such as more enquiries, higher conversion or better efficiency, ideally with context
- Lessons learned or challenges faced
Be cautious about results that sound too good without explanation. Ask how they were measured and over what period. Our article on agency red flags covers unrealistic promises.
Understand the agency's role
Many projects involve several parties. The agency might have done the design while another team built the website, or managed ads while the client produced content in-house. Ask:
- Which parts of this project did your team do?
- Who on your current team worked on it?
- Were any parts outsourced?
This prevents you from hiring an agency for skills that actually belonged to someone else.
Look for range and consistency
A good portfolio shows a consistent standard of quality across different clients, and enough range to show the agency adapts to each brand. If every project looks the same, the agency may apply one style to everyone, which may not suit you. If quality varies widely, ask why.
Talk to past clients
References are one of the best ways to verify a portfolio. Ask the agency for one or two clients you can speak with. Good questions to ask references:
- What was it like working with the agency day to day?
- Did they meet deadlines and budgets?
- How did they handle problems or disagreements?
- Did the project achieve its goals?
- Would you hire them again?
You can also look for reviews on Google or other platforms, keeping in mind that reviews can be selective.
Judge the presentation itself
How the agency presents its work is a clue to how it will work with you. Is the portfolio well organised and easy to understand? Do they explain their thinking? Can they talk confidently about trade-offs and decisions in each project? Thoughtful explanations usually signal a thoughtful process.
Match the portfolio to your brief
Finally, compare what you have seen with your project brief. Does this agency's work suggest they can solve your problem for your audience within your budget? Our guide to questions to ask before signing helps you dig further during conversations.
FAQ
What if an agency has no work in my industry?
That can be fine if they show strong process and relevant project types. Ask how they would learn about your industry and customers.
Should I trust awards in a portfolio?
Awards can signal creative quality, but they do not always reflect business results. Weigh them alongside case studies and references.
Can a new agency be a good choice?
Yes, if the team has relevant experience, a clear process and strong communication. Ask about the individuals' past work before the agency was formed.
A portfolio is the start of your evaluation, not the end. Look for relevance, real live work, clear results, honest explanations of the agency's role and good references.
