A downloadable case study template that forces students to show strategy, not just screenshots—prove your human-led decision-making to hiring teams in 2026.

Stop Showing Screenshots — Show Strategy

Hook: If your portfolio looks like a gallery of pretty screenshots, hiring managers will skim and move on. Employers in 2026 expect junior marketers and students to show not just what you made, but why you chose it, how you measured it, and what you learned — especially now that teams use AI for execution but reserve strategy for humans.

Why this matters now (short answer)

Late 2025 and early 2026 saw a clear pattern: organizations leaned into AI for speed and execution, but most leaders still distrust AI to make strategic decisions. A January 2026 MarTech summary of the 2026 State of AI and B2B Marketing report found that while ~78% use AI as a productivity engine, only a tiny fraction trust it with high-level positioning or long-term strategy. That means your advantage as a student or junior marketer is not to be faster with tools — it’s to be better at reasoning, trade-offs, and decision-making. A portfolio template that forces strategy and results instead of screenshots helps you prove that advantage.

Quick reality check: Employers want human strategy

AI tools are popular for drafting copy, generating variants, and automating tests. But employers are increasingly asking candidates to show the chain of thought behind decisions. They want:

Clear hypotheses that drove the work
Metrics that defined success before execution
Trade-offs and alternatives considered
Reflection on what you would change next

“Most B2B marketers see AI as a productivity booster, but only a small fraction trust it with strategic decisions like positioning or long-term planning.” — MarTech, Jan 2026

The portfolio case study template: structure and prompts

Use this template for every project you add to your marketing portfolio or student portfolio. It’s a story template — not a design checklist. Keep each section concise (recommendations below) and use strong headers so reviewers can scan.

Template fields (use this as a downloadable checklist)

Title & Role (10–15 words)
Who you were, what you did, and the channel.

Example: “Landing Page Redesign — Growth Intern (Acquisition, Q3 2025)”
Context & Constraints (50–100 words)
Business context, audience, timeline, budget, and team. Include constraints up front — hiring managers trust realistic context more than polished outcomes.
Problem Statement (1–2 sentences)
What was the specific problem you set out to solve? Tie it to a metric.

Example: “Organic landing page conversions were 1.2% vs. target 3% for our mid-funnel product.”
Hypothesis & Objectives (40–80 words)
What did you believe would fix the problem? State measurable objectives (KPIs) and the time window.

Example: “Hypothesis: Simplifying the hero and adding social proof will lift conversions to 2.5% within 6 weeks. Objective: +1.3 pp conversion and +20% time on page.”
Strategy Summary (80–150 words)
This is the heart of the case study. Explain the strategic approach — segmentation, positioning, channel mix, messaging hierarchy. Describe why this approach matched the context and constraints.
Execution (bulleted, 80–200 words)
List key actions, who did them (you, AI-assisted, teammate), tools used, and the cadence. Be explicit about where AI supported execution versus where human decisions guided strategy.
Metrics & Results (data-first)
Report the primary KPI and supporting metrics. Use a pre/post or A/B format. If results were mixed, be honest — explain why.
- Primary KPI: Conversion rate (from 1.2% → 2.3% = +1.1 pp; +92% relative)
- Secondary: Bounce rate, time on page, sessions, lead quality
Trade-offs & Alternatives (40–80 words)
What didn’t you do and why? Show you can prioritize. Mention experiments you deferred.
Key Learnings & Next Steps (50–120 words)
What would you change? What experiments would you run next? This shows growth-minded strategy, not finished perfection.
Appendix: Screenshots & Process Artifacts
Place screenshots and final assets here. Label each screenshot with a one-line caption explaining the decision it illustrates.

How to use the template: turn screenshots into strategy

Students often start with visuals — a campaign creative or site screenshot. To convert that into a story template, follow this 5-step framework:

1. Reverse-engineer the decision chain

For each visual, write down: what decision led to this, who made it, which hypothesis it tested, and what success metric it targeted. Don’t guess — ask teammates or check analytics where possible.

2. Map visual assets to objectives

Label each image in your appendix: “tested headline vs control” or “mobile hero with simplified CTA.” Connect each to a KPI in the Metrics section.

3. Be explicit about AI

Hiring teams in 2026 expect honest AI disclosures. For example: “Copy variants generated with AI, final selection based on manual user-test feedback.” This shows you understand tool boundaries.

4. Show trade-offs

Good strategy explains what you didn’t do. If you optimized for acquisition at the expense of brand consistency, say so and explain why.

5. Include a short reflection

Avoid “it was a success” summaries. Add a one-paragraph reflection: what surprised you, what failed, and your plan to improve.

Sample mini case (student-friendly)

Below is a condensed example using the template so you can see tone and level of detail expected.

Example: Email Welcome Flow — Marketing Intern

Context: SaaS startup with underperforming onboarding emails (Q4 2025). 2-person growth team, limited dev time, 3-week sprint.

Problem: New user activation rate (first-week product use) 18% vs. target 35%.

Hypothesis: Personalizing first two emails and adding a micro-CTA to schedule onboarding will increase activation to 30% in 4 weeks.

Strategy: Prioritize quick wins: segment by signup source, personalize subject/first line, and test micro-CTA vs. generic CTA. Chosen because development cost was low and personalization had strong prior lifts in similar cohorts.

Execution: Built segments in CRM (you), wrote variants (AI-assisted drafts + manual edits), launched A/B test, monitored daily for 28 days.

Results: Activation rose from 18% → 28% (+10 pp). Micro-CTA variant outperformed by 35% relative. Open rates up 8%.

Trade-offs: Did not implement in-app onboarding changes due to time/budget; those remain a high-priority next step.

Key learnings: Personalization improved activation but influenced higher-quality customers; next, add onboarding scheduling to product and measure 90-day retention.

Evidence and credibility: make it audit-ready

To convince recruiters, include links or screenshots of raw data (anonymize PII), A/B test summaries, and timestamps. Use a short appendix titled “Data sources & verification” with links to Google Sheets, GA4 reports, or CRM dashboards. If you can’t share proprietary data, summarize in ranges and include a note that precise numbers are available under NDA.

Rubric hiring managers use (and you should anticipate)

When reviewers scan cases, they implicitly check for a few things. Use this as a checklist to self-assess before you publish:

Clarity of objective — Was the primary KPI stated and measurable?
Strategic intent — Is there a clear hypothesis and rationale?
Execution detail — Can they tell what you did and who did it?
Results transparency — Are metrics present and verifiable?
Reflection — Are trade-offs and next steps discussed?

Portfolio SEO & LinkedIn tips (short, tactical)

Use keyword-rich titles: include terms like marketing portfolio, student portfolio, or portfolio template in case titles and meta descriptions.
Publish a 150–300 word case summary on LinkedIn with a CTA to view the full case on your site; attach one clear data point and a single insight.
Post a short thread (3–5 bullets) that explains the decision you made and tag mentors or teammates for visibility.
Include alt text on all screenshots that mentions the KPI and strategy (helps accessibility and SEO).

When to show tactics vs. strategy (use sprint vs. marathon thinking)

Inspired by 2026 martech conversations, consider whether the project was a sprint (rapid experiment) or a marathon (long-term brand work). For sprints, emphasize hypothesis, test design, and results. For marathons, emphasize positioning, long-term metrics (LTV, retention), and roadmap alignment. Label each case: “Sprint — conversion experiment” or “Marathon — brand positioning”.

Common questions & quick answers

Should I hide AI use?

No. Be transparent: describe where AI helped produce options and where human judgment made the final call. Employers trust honesty.

How long should each case be?

Readability beats length. Aim for 300–800 words per case with an appendix. A compact, results-focused story is better than a long-winded one.

What if results were negative?

Negative results are strategic gold. Explain the hypothesis, why it failed, and what you learned. That shows judgment and resilience.
