PIRET ILVER – SHOPPING SCIENCE IN ONLINE AND RETAIL WORLDS

Turning “why we buy” into words that sell.

Ever wondered why people buy or how to make them buy more without feeling pushy? That’s where shopping science comes in. I write marketing and retail stories, build data‑driven case studies, and speak about why we buy and how to sell more so you can use consumer psychology in the real world, not just in slide decks.

  • Articles on retail, e‑commerce and consumer psychology for your site, newsletter or publication.

  • Case studies that turn your campaigns, experiments and store data into compelling, credible stories.

  • Conference and event write‑ups you can publish in your own channels.

  • Selected talks and podcast guest interviews on why we buy and how to sell more when you need a writer who can also bring the story alive in audio or on stage.

Stories from the shopping lab

Let’s dive into how brands use shopping science to turn “maybe later” shoppers into “add to cart” and “I’ll take it” moments, both online and in physical stores.

Dove “Real Beauty”: 2% of Women Called Themselves Beautiful. Dove Decided to Change That.

Only 2% of women called themselves beautiful. Dove built a 20-year platform on that number and doubled sales in three years. It still cannot answer one question.

Jellycat: Why Adults Queue for Hours to Buy a Smiling Croissant

Jellycat revenue grew 70% to GBP 333 million while the toy market shrank. The strategy: retirement dates, staged pop-ups and a billion TikTok views it never paid for.

Heinz Ketchup Fraud: When the Bottle Says Heinz and the Ketchup Doesn’t

Restaurants were refilling Heinz bottles with cheap ketchup. Instead of hiding it, Heinz turned it into a public crime scene. Sales rose 8% and 33 new contracts followed.

Impossible Ads: Louis Vuitton, PODS and Maybelline

A 73-metre trunk facade, a truck that rewrites itself every block, and a fake Tube train with eyelashes. Three impossible ads, three very different strategies.

    Piret Ilver consumer psychology and shopping science expert

    Hi, I'm Piret Ilver

    SHOPPING SCIENCE IN ONLINE AND RETAIL WORLDS

    I’m Piret Ilver, an entrepreneur and shopping science nerd who studies how people have shopped for over a hundred years from the first department stores to today’s e‑commerce giants.

    Together with my team, I’ve built the Estonian sock brand Sokisahtel  and gourmet salt brand Salt’sUp, and I launched my first online store back in 2005.

    That day‑to‑day work in retail and e‑commerce is the lens I use to write about shopping history, brand origin stories and case studies from around the world, how different companies test ideas, learn from shoppers and turn those insights into sales.

    Writing these stories is my passion project: I love unpacking how big and small brands started, what they tried, what actually worked and how you can borrow those ideas for your own retail or e‑commerce business.

     

    Alongside that, I work with small business owners through e‑commerce and social media trainings, practical AI‑tool workshops, 1:1 consulting and mentorship helping them turn shopping history and brand stories into concrete next steps for their own shops.
