How to turn your client work into compelling portfolio case studies — including what to include, how to handle NDAs, how to ask clients for results, and how to use AI to make the writing process faster.

As your business grows and you land your first few clients, it's time to start updating your portfolio with real work. Everyone's updating schedule is different, but I find it easiest to update mine every time I need new clients — which usually works out to every 3–9 months.
Now that you've moved past mock-up pieces for fictitious clients, you can replace those with the real thing. Here's how to do it well.
Why case studies beat work samples
If you want your portfolio to actually convert potential clients — not just impress them — format your work as case studies rather than just links or screenshots.
A case study shows:
- You've worked with companies like theirs that had similar goals
- You understand strategy, not just execution
- You can get results — not just deliver deliverables
Your ideal clients are looking for proof that you've done this before and can do it for them. A case study gives them that proof in a way a raw work sample simply can't.
How to create a case study
For each client you want to feature, gather the 5 W's (and an H): who, what, where, when, why, and how.
WHO Share a little about the company — what they do, who they serve, their industry. You don't need to go deep, just enough to give context.
WHAT What were their goals when they hired you? What was the scope of work? If the scope changed during the project, note that and explain how you adapted.
WHEN When did you do the project and how long did it take?
HOW Walk through your process. This is where you show your methodology and what makes you different. Depending on your service, this might include:
- How you approached the strategy before executing
- How you researched the audience or audited existing work
- Tools or frameworks you used
- Any briefs, outlines, or plans you created first
- How you collaborated with the client or their team
Include screenshots of things like SEO plans, content briefs, email workflows, or brand voice documents where relevant — just redact any sensitive information first.
WHY Why did you approach the project the way you did? This is where you show your expertise and strategic thinking. What informed your decisions? What were you trying to achieve and how did your approach get you there?
WHERE Where did the work appear or live? Grab screenshots if you can't share a live link. For capturing full-page screenshots, I use GoFullPage (Chrome extension, free) or CleanShot X (Mac app, paid — the scrolling capture feature is excellent). Both work well for emails, web pages, copy in the wild, product descriptions, and anything else that doesn't have a shareable link.
If you revamped or refreshed existing work, try to get before and after screenshots. The contrast is compelling.
RESULTS (optional but powerful) Share whatever metrics you have access to. Screenshots are more compelling than text if you can get them.
Results can look like:
- Blog posts ranking on the SERP
- Traffic stats or growth over time
- Email open rates and click-through rates
- Conversion rates or revenue driven
- Subscriber growth
- Engagement metrics for social content
- AI search visibility improvements
- Testimonials from the client about specific outcomes
- Brand voice adoption across a team
To get this information, request access to the client's Google Analytics, Search Console, email platform, or whatever's relevant. If you can't get direct access, ask the client for screenshots or numbers. Let them know it's just for your portfolio — most clients are happy to help.
What if you can't share the work publicly?
This comes up all the time, especially with larger clients who have NDAs. You have a few options:
- Describe the project without showing it — write the case study with all the context, process, and results, but note that the work is confidential. Serious clients understand this.
- Use anonymized screenshots — blur or crop out identifying brand details if the work itself is what you want to show
- Get written permission — sometimes clients will give you permission to share a specific piece even if there's a general NDA in place. It never hurts to ask.
- Lead with results — if you can share the outcome data without showing the actual deliverable, that's often more compelling anyway
When NOT to include something
Not everything deserves a spot in your portfolio. Leave out:
- Work you're not proud of or that doesn't represent your current skill level
- Work from niches or service types you're trying to move away from
- Projects where the client over-edited your work and the final product doesn't sound like you
- Anything that doesn't reflect where you want to go next
Your portfolio should be a curated argument for why someone should hire you — not a complete archive of everything you've ever done.
What about spec work or personal projects?
If you're still building out client work, spec pieces are completely valid portfolio entries — as long as you're transparent about what they are. A well-crafted spec SEO strategy for a brand you admire, a sample brand voice guide for a fictional client, or a mock email sequence for a real product can all demonstrate your skills effectively.
As you land real clients, swap the spec pieces out. But don't wait until you have a full client roster to start showing your work.
Using AI to write your case studies
Case studies are one of the best places to use AI in your portfolio process. Once you have your notes, client answers, and any results pulled together, you can feed all of that into Claude along with the case study framework from the How to Write Case Studies lesson [link to come] and ask it to draft the case study for you.
You'll still need to edit it in your voice — but it'll save you a significant amount of time and help you structure the information in a compelling way.
Keeping your portfolio updated automatically
If you write bylines for publications, Authory is worth looking into. It automatically pulls in your published work from across the web so your portfolio stays current without you having to manually add each piece. Particularly useful if you're regularly publishing content for multiple clients or publications.
How to ask clients for results
Not sure how to request the stats you need? Here's a template — pull only the questions that apply to your work:
Hey [client],
I'm working on updating my portfolio and I'd love to include a case study of the work I've done for you. To make it as useful as possible, I'd love to include some metrics that show what we accomplished together.
Would you be able to share any of the following?
For content and SEO work:
- How are any of the pieces I worked on ranking on Google, and what traffic are they driving?
- Have you seen any changes in overall organic traffic since we started working together?
For email marketing:
- Open rates and click-through rates for the emails or sequences I worked on
- Any revenue or conversion data tied to those campaigns
For brand voice and strategy work:
- Any feedback from your team on how the brand voice guide or strategy has been used
- Any measurable outcomes you've seen since implementing it
For social media:
- Follower growth, engagement rates, or reach changes during the time I was creating content
A screenshot is totally fine if that's easier than pulling numbers. This is just for my portfolio — I want to show potential clients the kind of results we can get together.
Thanks so much![Your Name]

A quick note on timing
Don't wait until you need clients to update your portfolio — by then you're already behind. Every time you wrap a project, spend 30–60 minutes capturing the key details while they're fresh. Screenshots, results, notes on your process. Even if you don't build the full case study right away, you'll have everything you need when you do.
