Alper Tunga Yazgan Mercan Copywriter and Content Strategist · Istanbul, GMT+3
Portfolio · 2026

The right tone, the right voice, the right words.

I am a copywriter and content strategist based in Istanbul, working in English and Turkish for consumer and B2B brands. Social and LinkedIn copy, campaign concepts, executive accounts, long form editorial, and the systems that hold one voice steady across all of them.

Recent clients include Gloria Jean's Coffees, Magnolia Bakery, AXA Sigorta, QNB Sigorta, Keller Williams, Polat Holding and Raku Coffee Roastery. My instinct for narrative and tone comes from a background in film, music journalism and photography.

What you can hire me for

Brand voice and social copy

LinkedIn and Instagram copy in Turkish or English, written so several accounts can post on the same day without sounding like the same person.

Campaign concepts

One idea turned into a repeatable format, a naming system and a publishing calendar, so a campaign outlives its launch week.

Executive ghostwriting

Thought leadership for founders and board level executives, written in their own voice and cleared for brand risk before it goes out.

SEO and GEO content

Articles built to rank on Google, win featured snippets and be quotable by ChatGPT, Gemini and Perplexity, without reading like SEO filler.

Turkish localisation

Global brand material rebuilt in Turkish rather than translated, with terminology, register and cultural references checked line by line.

Editorial and research

Competitive landscape reports, category language audits and long form features, usually the groundwork a content strategy is built on.

Brand voice and social

One writer, several brands, no two of them alike

I write LinkedIn copy for the brands under Dinçerler Group. The real job is keeping every brand in its own character while they post on the same day, for the same occasion, side by side in the same feed. Two examples from the same morning.

International Women's Day

Magnolia Bakery Türkiye · 8 March · LinkedIn

Published copy, translated from Turkish

New York, Bleecker Street, 1996.

A small bakery opened by the passion of two women.

Today Magnolia Bakery lives on around the world with that same excitement.

For the women on our team who carry that heritage forward in Istanbul every day, with sweet and patient work, we made a short film. We hope you enjoy it.

Happy International Women's Day.

Original Turkish

1996'da New York, Bleecker Caddesi.

İki kadının tutkusu ile açılan küçük bir pastane...

Bugün Magnolia Bakery aynı heyecanla dünyanın dört bir yanında yaşamaya devam ediyor.

İstanbul'da bu mirası her gün tatlı emeğiyle sürdüren kadın çalışma arkadaşlarımız için özel bir film hazırladık. Keyifli seyirler.

8 Mart Dünya Emekçi Kadınlar Günü kutlu olsun.

The copy opens with the brand's own founding story and draws an unbroken line from a New York bakery in 1996 to the women keeping that craft alive in Istanbul today. The occasion is honoured through the brand's history rather than borrowed from a template.

International Women's Day

Gloria Jean's Coffees Türkiye · 8 March · LinkedIn

Published copy, translated from Turkish

Coffee is a matter of patience.

Knowing the bean, knowing the roast, getting the timing right.

We grow alongside the women on our team who show that patience every day, in more than 240 stores across more than 50 cities.

Today we wanted to thank them with a short film. We hope you enjoy it.

Happy International Women's Day.

Original Turkish

Kahve işi sabır işi.

Çekirdeği tanımak, kavurmayı bilmek, zamanlamayı tutturmak.

50'den fazla şehirde 240'tan fazla şubemizde bu sabrı her gün gösteren kadın çalışma arkadaşlarımızla birlikte büyüyoruz.

Bugün onlara teşekkürümüzü özel bir filmle iletmek istedik. Keyifli seyirler.

8 Mart Dünya Emekçi Kadınlar Günü kutlu olsun.

Same day, same group, a completely different voice. Here one idea carries the whole post: patience. Knowing the bean, knowing the roast, getting the timing right. The craft behind the cup becomes the way to credit the women behind the counter. Grounded, unhurried, no ceremony.

A kitchen tour that turned into a story about craft

Magnolia Bakery Türkiye · Employer brand · LinkedIn

Published copy, translated from Turkish

Today we hosted some very special guests at our Central Kitchen.

Students from the Yıldız Technical University Food Club came to see our production processes and kitchen operations up close. Showing the careful preparation behind every product, our hygiene standards and the daily rhythm of the kitchen to the food professionals of the future was the best possible way to explain how this work actually gets done.

On a day spent talking about how theory meets practice, the students' curiosity brought fresh energy into our kitchen.

Original Turkish

Bugün Merkez Mutfağımızda çok özel misafirler ağırladık.

Yıldız Teknik Üniversitesi Gıda Kulübü öğrencileri, üretim süreçlerimizi ve mutfak operasyonlarımızı yakından tanımak için Merkez Mutfağımızı ziyaret etti. Her ürünün arkasındaki titiz hazırlık aşamalarını, hijyen standartlarımızı ve günlük işleyişini geleceğin gıda profesyonelleriyle paylaşmak, bu işin mutfağını anlatmanın en güzel yanıydı.

Teorinin sahada nasıl karşılık bulduğunu birlikte konuştuğumuz bu günde öğrencilerin merakı ve ilgisi, mutfağımıza taptaze bir enerji getirdi.

Behind the scenes employer brand content. A routine kitchen visit becomes something worth reading because the students' curiosity, not the company's process, is the thing being described.

Campaign concepts

From one sentence to a system that keeps publishing

I take the creative lead on turning a single persuasive idea into a full campaign. Concept, format and copy architecture are mine. Design is by the Contenthink team.

From the Barista's Eyes

Gloria Jean's Coffees Türkiye · LinkedIn series · Concept and copy

Not a one off post but a repeatable LinkedIn series. The format works like a system: every post is a city, every city is an observation seen through a barista's eyes, and every observation finds its own way to a Gloria Jean's product. The naming convention, the posting rhythm and the editorial calendar all sit under one concept, which means the client can keep running it without me in the room.

What I Learned From My Mother

Dinçerler Group · Mother's Day · Concept, structure and copy

A multi brand campaign built on a single idea. It inverts the achievement announcement that LinkedIn runs on: instead of titles and certificates, people post the one real lesson their mother taught them. Every part of the campaign, from concept to publishing schedule, comes out of that inversion.

  • ConceptReplace corporate titles and certificates with something more honest and more personal.
  • Gloria Jean's postA LinkedIn post drawing a parallel between the care that goes into coffee and a mother's love.
  • Account copyReady to publish posts in a separate voice for each brand account, including the chairman and a board member.
Published copy, translated · Mehmet Dinçerler

I have read a great deal about leadership. I have watched many people closely. But looking back, I can see that the first place I learned it was not a meeting room. The person who taught me that lesson held no title. She was simply my mother.

She made decisions, quickly. She took responsibility, without stepping back. She trusted us, her team, but she never let the standards slip. And she did all of it quietly. Without waiting for praise, without asking for credit.

This Mother's Day I write with gratitude and love for my mother, and for every mother whose work no title could ever contain. Happy Mother's Day.

Original Turkish

Liderlik üzerine çok şey okudum. Pek çok insanı yakından izledim. Ama geriye dönüp baktığımda, liderliği ilk öğrendiğim yerin bir toplantı odası olmadığını görüyorum. O dersi bana veren kişinin unvanı yoktu, sadece annemdi.

Karar alırdı, hızlı. Sorumluluk alırdı, geri adım atmadan. Bize, yani ekibine, güvenirdi; ama standartlardan hiç ödün vermezdi. Bütün bunları sessizce yapardı. Övgü beklemeden, kredi talep etmeden.

Bu Anneler Günü'nde anneme ve emeğini hiçbir unvana sığdıramadığımız tüm annelere minnet ve sevgiyle yazıyorum. Tüm annelerin Anneler Günü kutlu olsun.

Mehmet Dinçerler Dinçerler Group Mother's Day quote card
As published, Mehmet Dinçerler · Dinçerler Group
Published copy, translated · Gloria Jean's

The taste of a hot coffee shared with your mother at home is very hard to imitate.

There is care in that coffee. Patience, love and effort.

As the Gloria Jean's Türkiye family, we try to carry the values our mothers taught us into every cup. Because good coffee, like a mother's love, cannot be rushed.

Today is a good day to remember that warmth and share it with the people you love.

Happy Mother's Day to all mothers. 💛

Original Turkish

Evde anneyle birlikte içilen sıcak bir kahvenin tadı ve hatırı taklit edilmesi çok zor.

O kahvede özen vardır, sabır vardır, sevgi ve emek vardır.

Gloria Jean's Türkiye ailesi olarak biz de annelerimizin bize öğrettiği bu değerleri her fincanımıza taşımaya çalışıyoruz. Çünkü iyi bir kahve tıpkı annenin sevgisi gibi aceleye gelmez.

Bugün o sıcaklığı hatırlamak ve sevdiklerinizle paylaşmak için güzel bir gün.

Tüm annelerin Anneler Günü kutlu olsun. 💛

Executive voice

Leadership communication that sounds like a person

I write for the personal LinkedIn account of Mehmet Dinçerler, Chairman of Dinçerler Group, in his voice and from his point of view. High trust, brand sensitive work where every sentence is attributed to a real person by name.

Five store openings, written as a quality story

Mehmet Dinçerler, Chairman · Growth announcement · LinkedIn

Published copy, translated from Turkish

As we bring Gloria Jean's Coffees to more cities across Türkiye, the thing that matters most to us is that every store we open delivers the experience the brand deserves from its very first day.

With five new stores in Istanbul Finance Center, Ankara Bahçelievler, Mardin, Şanlıurfa and Manisa, we both met our guests in new cities and established our brand standards carefully in each one.

From coffee quality to the way we think about service, from the atmosphere of a store to how our teams welcome a guest, every detail was planned with real care. I am endlessly grateful to my colleagues for the dedication and effort they put into this process.

Moving at a steady pace, our goal is to bring Gloria Jean's Coffees to guests all over Türkiye with the same quality and the same warmth.

On this journey we will keep creating together, growing together, and meeting our guests in more cities.

Original Turkish

Gloria Jean's Coffees'i Türkiye'nin daha fazla şehrine taşırken bizim için en önemli konu, açtığımız her mağazanın ilk günden itibaren markanın hak ettiği deneyimi sunması.

İstanbul Finans Merkezi, Ankara Bahçelievler, Mardin, Şanlıurfa ve Manisa'da açtığımız beş yeni şube ile hem yeni şehirlerde misafirlerimizle tanıştık hem de markamızın standartlarını her birinde özenle kurmayı başardık.

Kahve kalitesinden servis anlayışına, mağaza atmosferinden ekiplerin misafiri karşılama biçimine kadar her detayın ne kadar titizlikle planlandığı bu süreçte ekip arkadaşlarımızın özverisi ve emeği için sonsuz teşekkür ediyorum.

İstikrarlı bir tempoyla ilerlediğimiz bu yolda hedefimiz, Gloria Jean's Coffees'i Türkiye'nin dört bir yanında aynı kalite ve aynı sıcaklıkla misafirlerimizle bir araya getirmek.

Bu yolculukta birlikte üretmeye, birlikte büyümeye ve daha fazla şehirde misafirlerimizle buluşmaya devam edeceğiz.

An expansion announcement is the easiest post in the world to write badly, because the numbers do the talking and the reader hears boasting. The brief here was to make five openings read as an operating standards story instead: the milestone is the consistency, not the count. The credit goes to the teams, and the closing line, we keep growing together, carries into the creative as the campaign lockup.

A product tied to children's education

Mehmet Dinçerler, Chairman · April · LinkedIn

Published copy, translated from Turkish

On the journey we began last year with our teddy bear sleeves, we contributed together to children's access to quality education. This year we are taking that story one step further.

Our Penguin Cups, developed together with TEGV, arrive in every Gloria Jean's Coffees Türkiye store from 23 April. The revenue from every cup sold goes to education projects for children.

At Dinçerler Group we care about creating real value in everything we do. We will keep working towards a world where every child can reach quality education.

Original Turkish

Geçen yıl ayıcık sleeve'lerimizle başlattığımız yolculukta, çocuklarımızın nitelikli eğitime erişimine hep birlikte katkı sağladık. Bu yıl, bu anlamlı hikayeyi bir adım öteye taşıyoruz.

TEGV iş birliğiyle hazırladığımız "Penguen Bardaklar", 23 Nisan itibarıyla tüm Gloria Jean's Coffees Türkiye şubelerimizde yerini alıyor. Satılan her bardağın geliri, çocuklarımızın eğitim projelerine aktarılacak.

Dinçerler Group olarak, yaptığımız her işte anlamlı bir değer yaratmayı önemsiyoruz. Her çocuğun nitelikli eğitime ulaşabildiği bir dünya için çalışmaya devam edeceğiz.

A purpose led announcement that connects a physical product, the Penguin Cups made with TEGV, to children's access to education. Measured and personal, with feeling but no performance of it.

International Women's Day, in the chairman's voice

Mehmet Dinçerler, Chairman · 8 March · LinkedIn

Published copy, translated from Turkish

Every day we witness the work, the energy and the contribution of the women behind our journey.

It is difficult to fit what we have achieved together with them into words. Happy International Women's Day to every woman who makes a difference through her work and inspires the rest of us.

Original Turkish

Yolculuğumuzun arkasındaki kadın çalışma arkadaşlarımızın emeğine, enerjisine ve katkısına her gün tanıklık ediyoruz.

Onlarla birlikte yakaladığımız başarıları kelimelere sığdırmak zor. Emeğiyle fark yaratan ve bize ilham veren tüm kadınların 8 Mart Dünya Kadınlar Günü kutlu olsun.

Published the same morning as the brand posts above and coordinated with them. Personal but professional, and pitched one notch more restrained than the brand voice, because a named person carries a different kind of risk than a logo does.

SEO, GEO and editorial

Written to rank, and to be cited by machines that answer

Beyond social, I write long articles that perform in search and still read like they were written for a person. Search is no longer only a list of links, so the same article has to satisfy a reader, a snippet and a language model.

QNB Sigorta, an SEO and GEO blog system

I write the insurance blog programme for QNB Sigorta on a system built to do three things at once: rank on Google, win featured snippets, and be quotable by AI search tools such as ChatGPT, Gemini and Perplexity. Each article opens with a real problem in plain language, gives the reader's answer early so a machine can lift it cleanly, then earns the rest of the reader's attention with context and experience. Headings are written as the questions people actually type.

Accuracy is the part clients underestimate. Every claim is checked against the insurer's live product terms, age limits and coverage before it goes anywhere near a draft. On one project I found that the client's own product pages still carried an outdated state contribution rate for private pension plans and flagged it before publishing.

18 articles across three product lines

Client articles available on request.

AXA Sigorta, editorial review and localisation

I worked on the Turkish edition of a long foresight report and on newsletter localisation for AXA Sigorta. This was not sentence by sentence translation. I ran a multi pass review for terminology consistency, structure and register, then rewrote the passages where the English original did not survive the crossing into Turkish insurance language. Documents like this are exactly where translated copy usually fails, because the terms are technical and the tone has to stay authoritative while it changes language.

Turkish specialty coffee, a competitive landscape report

For Raku Coffee Roastery I put together a market intelligence report on the Turkish specialty coffee scene: how the main players position themselves, where the category language has worn thin from repetition, and which gaps a small roaster can credibly own. The content strategy came out of that report rather than the other way around, which is the order I prefer to work in.
