What Marketing Interns Actually Do in European Host Companies

• Plan and schedule weekly social-media posts across LinkedIn, Instagram and TikTok.
• Draft blog posts, newsletters and product copy in English (and sometimes the local language).
• Run keyword research and on-page SEO checks for 5–10 pages per month.
• Pull weekly traffic and engagement reports from GA4, Meta Business Suite and HubSpot.
• Support paid-ads operations: creative uploads, UTM tagging, A/B variants.

• Analytics — Google Analytics 4, Meta Business Suite, LinkedIn Analytics.
• Content — Notion, Google Workspace, Canva, Figma (basic), CapCut.
• SEO — Ahrefs or Semrush (read-only seats), Google Search Console.
• CRM / automation — HubSpot, Mailchimp, Klaviyo, ActiveCampaign.

• Working English (B2 minimum); a second European language is a strong plus in Spain, Portugal and Italy.
• Basic copywriting in your native language plus English.
• Comfort with spreadsheets, simple charts and reading a funnel report.
• Visual literacy: cropping, resizing, brand-safe templating in Canva or Figma.

Most placements end with a written evaluation and an Europass Mobility document. Common KPIs:

• Number of pieces shipped (posts, articles, emails) per month.
• Engagement-rate uplift on owned channels.
• SEO health-score improvement on assigned pages.
• CRM list cleanliness (bounce rate, deduplication rate).

Hiring managers reviewing junior marketing CVs spend roughly 30 seconds on the portfolio. Two patterns consistently win interviews: a Notion or Webflow page with three case studies of 200–300 words each, and a single PDF with screenshots, the brief, the constraint and the result. We have reviewed several hundred Erasmus+ marketing intern portfolios and the same gaps recur — no numbers, no constraint described, no before/after.

• Case 1 — 'I owned the LinkedIn calendar of a Lisbon B2B SaaS for 4 months: 48 posts shipped, follower count from 2,100 → 3,400, engagement rate 1.8% → 3.1%.'
• Case 2 — 'I ran a 6-page on-page SEO audit for a Barcelona e-commerce host: average position 18 → 9 across the focus pages, organic CTR +42%.'
• Case 3 — 'I cleaned 14,300 contacts in HubSpot, deduplicated 1,200 records and re-built the welcome sequence: open rate 22% → 31%, bounce rate 4.1% → 0.8%.'
• Each example pairs a verb, a number, a tool and a constraint — that is the entire formula.

European marketing internships are not interchangeable. The host-company mix changes the day-to-day work substantially, and matching the city to your career goals saves a year of CV rewriting later.

• Barcelona — heavy on 22@ scale-ups; lots of SaaS, fashion and travel-tech; English-first; portfolio bias toward growth marketing.
• Lisbon — Web Summit halo, fintech, design-forward startups; strong content and brand work; mid-level English-Portuguese bilingual roles dominate.
• Berlin — B2B SaaS, marketplaces, climate tech; demand recovering since 2024; strong on lifecycle and CRM marketing.
• Milan — fashion, luxury, FMCG; more traditional brand and PR work; Italian helpful, sometimes required.
• Dublin — multinational HQs (Google, Meta, Stripe EMEA) with structured intern programmes; competitive entry.

Pick the city by the segment of marketing you want to grow into, not by climate. A four-month placement will compound for years if the host's funnel matches your future job description.

The strongest marketing intern handovers we have seen all share a small set of artefacts. Producing them takes 4–6 hours in your final week and pays back at every interview for the next two years.

• A single Notion page with the campaigns you owned, the assets, the numbers and the lessons learned.
• A short Loom (under 5 min) walking through your three best pieces of work, voiced in your own words.
• A written reference from your supervisor — request it in week 14, not week 16, when calendars are tighter.
• An updated LinkedIn with the host's name, your concrete contributions and one media asset embedded.
• A clean handover doc for your replacement — interns who do this are remembered (and hired back full-time more often than they expect).
