Digital Marketing Portfolio Kit

Last reviewed: September 2026

Recruiters hiring junior marketers want evidence that you can plan, execute and measure, not just a list of certificates. You can create that evidence without an agency job: run small real projects, document them honestly, and show what you learned from the numbers.

Before you start: set up free accounts for Google Analytics 4, Google Search Console, Google Ads (Keyword Planner) and a Meta Business account, plus a free tier of an email tool. Free certifications from Google Skillshop and HubSpot Academy are useful to structure learning, but the projects below are what you'll talk about in interviews.

1. Six practice projects

Project 1 — SEO audit and content plan

What to do: pick a small local business site (or a friend's). Audit technical basics (indexing, page speed, mobile, titles/meta, internal links), do keyword research, and write a 3-month content plan with 6–8 target topics.

Show: audit findings ranked by impact, a keyword map (topic → keyword → intent → page), and one optimised page draft.

Project 2 — Paid search campaign plan (and a small live test if possible)

What to do: build a Google Ads search campaign structure for a local service: campaigns, ad groups, keywords with match types, negative keywords, 3 ad variations, and a budget and bidding plan.

Show: the account structure, ad copy, landing-page recommendations and how you'd judge success (CPC, CTR, conversion rate, cost per lead). If you ran a small live test, report real numbers only.

Project 3 — Meta (Facebook/Instagram) ads creative test

What to do: for a real or mock brand, define audiences, plan a creative test (e.g. 3 hooks × 2 formats), and set up tracking. With a small budget, run it for a week.

Show: the hypothesis, creatives, targeting, results table and what you'd scale or kill.

Project 4 — Email welcome sequence

What to do: write a 4–5 email welcome or nurture sequence for a course, D2C brand or newsletter; build it in an email tool with segmentation and a clear goal per email.

Show: the sequence map, subject-line variants, the metric for each email (open, click, reply, purchase) and an A/B test plan.

Project 5 — Content and social growth experiment

What to do: run a 30-day LinkedIn or Instagram content experiment on a topic you know. Plan pillars, post consistently, and change one variable at a time (format, hook, posting time).

Show: the content calendar, top and bottom posts with reasons, and follower/engagement trends. Small numbers are fine if the thinking is clear.

Project 6 — Analytics and reporting dashboard

What to do: use the Google Merchandise Store GA4 demo account (Google's public demo property) or your own site's data. Build a Looker Studio dashboard for traffic sources, conversions and landing pages.

Show: the dashboard, three insights and the recommendation each one leads to. Explain UTM tagging and how you'd attribute conversions.

2. One-page case-study template

  1. Context: brand/business, audience, and your role (solo, team, real client or practice).
  2. Goal: one primary metric and a target (e.g. "get 30 leads at under ₹X each" — use your real target).
  3. Strategy: channels chosen and why; what you deliberately didn't do.
  4. Execution: key assets (ads, pages, emails, posts) with screenshots.
  5. Results: a small table of actual numbers with the date range. Say clearly if the budget was tiny.
  6. What I learned / would do next: the most useful part for interviewers.

Honesty matters: never inflate results or present a practice project as a paid client engagement. Interviewers will ask follow-up questions.

3. Metrics you should be able to explain

  • CTR = clicks ÷ impressions. CPC = spend ÷ clicks. CPM = spend ÷ impressions × 1,000.
  • Conversion rate = conversions ÷ clicks (or sessions — say which).
  • CPL / CPA = spend ÷ leads (or acquisitions).
  • ROAS = revenue from ads ÷ ad spend.
  • CAC = total sales and marketing cost ÷ new customers; compare with customer lifetime value (LTV).
  • Bounce/engagement rate in GA4: GA4 reports engagement rate; bounce rate is its inverse.

4. Interview questions freshers get asked

  1. What is the difference between SEO and SEM / performance marketing?
  2. How does Google decide where a page ranks? Name on-page, off-page and technical factors.
  3. What are keyword match types in Google Ads?
  4. What is Quality Score and how can you improve it?
  5. How would you spend ₹50,000 to generate leads for a local coaching institute?
  6. Our cost per lead doubled this month. How would you investigate?
  7. What is a funnel? Give an example of top, middle and bottom-of-funnel content.
  8. What is retargeting, and what are its privacy limits?
  9. What are UTM parameters and why do they matter?
  10. Explain the difference between ROAS and ROI.
  11. How would you decide between Meta ads and Google Search ads for a new product?
  12. What makes a good landing page?
  13. Walk me through a campaign you ran. What would you change?
  14. Which marketing campaign did you admire recently and why?
  15. How do you stay updated on platform changes?
