How to Evaluate a Web Design Portfolio (Without Falling for Pretty Screenshots)
Web design portfolios are curated to deceive. Every agency shows you their best work, their best photos, their best clients. Here’s how to evaluate a portfolio honestly — the 7 checks that separate ‘this firm can ship for you’ from ‘they got lucky once.’
№ 01Check 1: Click through to live sites
Portfolio screenshots can be 6 months out of date. Worse, the live client may have rebuilt on Wix or fired the agency. Always click through. If a portfolio has 12 ‘case studies’ and only 4 link to live sites, the other 8 are dead clients.
What you’re looking for: the site loads, the design matches the screenshot, the agency’s credit isn’t quietly removed from the footer, and the page does what the case study claims.
№ 02Check 2: Lighthouse audit each site
Open a portfolio site in Chrome Incognito. Run a Lighthouse audit. Performance + Accessibility + SEO scores. A ‘modern’ agency whose portfolio sites score 35 / 60 / 70 on a freshly-built site is shipping pretty wallpapers, not engineering.
Reasonable benchmarks for a recent build: Performance 75+, Accessibility 95+, SEO 95+. Anything below 65 on Performance for a fresh build is a red flag; below 80 on Accessibility means ADA compliance hasn’t been considered.
№ 03Check 3: Read the copy
If every site in the portfolio uses the same phrases (‘passionate about your success,’ ‘delivering results that matter,’ ‘comprehensive solutions for your business’), the agency is using templated copy across clients. That’s fine if you’re getting them at template-copy pricing. It’s not fine at $15K+.
The signal you want: each portfolio site has distinct copy that sounds like the client’s industry voice. Manufacturing copy sounds like manufacturing. Healthcare sounds like healthcare. Generic agency cheese on every page = the agency doesn’t engage with copy as a deliverable.
№ 04Check 4: Look at the work timeline
How many projects has the agency shipped in the last 12 months? If their case studies are all 2-3 years old, they may have stopped shipping. If they have one ‘flagship’ case study from 2019 they keep linking to, you’re hiring on past glory.
Healthy agencies ship 8-30 projects per year (depending on team size). Their portfolio should be visibly updated within the last 3-6 months.
№ 05Check 5: Ask for references they didn’t put on the site
The cases on the website are the 5-10 best results. Real signal comes from references the agency didn’t pre-select. Ask for: ‘three clients who had average outcomes’ or ‘a client whose project had problems and how you resolved them.’
Agencies that get defensive at this request are the ones whose portfolios are misleading. Healthy agencies have nothing to hide; the average client outcome is fine, the problem-resolution story makes them look professional.
⚠What to avoid
- Evaluating a portfolio on aesthetic taste alone. ‘I love how the site looks’ tells you the screenshot is well-designed; it tells you nothing about whether the site converts or whether the team will execute for you.
- Falling for agency-of-record badges. ‘Tampa Bay Business Journal Top 10′ or ’40 Under 40 Founder’ are not technical signals. They’re marketing achievements.
- Believing case study traffic + revenue numbers without asking how they’re attributed. ‘Traffic up 247%’ could be from a paid campaign, a viral post, or seasonal variance, not the website itself.
