Outsource writing and make time for what YOU love to do.

Hi! I’m Marijke.

I’m one of those people who was lucky to find out what they love to do at an early age: writing informative texts about nature and nature-related hobbies, especially fishkeeping.

Sounds silly — aren’t you supposed to want to write poetry or high literature ? — but there’s nothing I like more than translating science into accessible magazine articles, how-tos, blog posts, and explainers.

Few things make me happier than getting to sit down with a stack of papers and a clear brief! That’s why I’ll never outsource my work to an LLM.

Here are some things I’m proud of:

Getting my Bachelor’s Degree in Communication Science

Moving from The Netherlands to Spain to start working on my business full-time right out of uni

Selling my first niche website at 24

Selling my second niche website at 26

Being published in four print magazines by 28

Running multiple clients’ blogs by 30

Being able to spend every day writing for the best clients in the world!

Enough about me, though… what story do you need told?

My interests stretch far beyond just aquariums and fishkeeping. My other loves include (indoor) gardening, cooking & recipes, travel, and ornithology. Currently particularly interested in taking on work relating to traveling in Spain, recipes, and indoor and outdoor plants, all with original photography included.

Travel & Destinations

I’m from The Netherlands, live in Spain, and am an expert on several other destinations, including Istanbul. Here is an example on Tabarca Island in Alicante from my blog, Snorkel Things (on hiatus):

Visit Isla de Tabarca: Snorkeling, Arroz & More

Food & Recipes

I love cooking and everything to do with food! My happy place is in the kitchen and surrounded by my loved ones at the dining table. Here’s my Valencian paella explainer & recipe (no chorizo!):

Spanish Paella Explained + Recipe for Paella Valenciana

Indoor Gardening & Terrarium

Houseplants are one of my prime areas of expertise; I’ve written 200+ articles about them (and own around 100 indoor plants). They’re green, they’re alive, and they’re proven to make people happy.

Caring for an Indoor Pineapple Plant

Gardening & Growing Food

Whether it’s edible gardening or growing the prettiest flowers, I’ve got you covered — I’m a homesteader myself. Check out one of the many gardening guides I’ve written over the years:

Tips for Extending the Tomato Season

Pet care niche (aquariums)

Aquariums (freshwater and marine) were my first ever niche topic. I’ve written 500+ articles about fishkeeping, and I’m still going strong! You can find many samples over at FantaSEA Aquariums, like this one:

Peppermint Shrimp: Aiptasia’s Worst Nightmare (Care & Info)

Pet care niche (parrots)

I currently live with two cockatiels and three budgies, so this is a topic dear to my heart. I’ve written 200+ parrot care articles, including this kakariki parrot care guide for my website Psittacology (currently on hiatus):

Kakariki Parrot Care, Diet, Housing & Bonding

Pet care niche (dogs, cats & more)

Dogs, cats, rodents, ferrets, reptiles and amphibians galore! Heck, even tarantulas and scorpions are welcome. I love writing about any type of animal, even the creepy crawly ones, and their care. Read an example:

Pop science

I adore everything to do with spreading the word about (protecting) the natural world and the wonders of this planet we call home. You can find an example of my pop science writing here:

Bird, Plane, Or Caribbean Reef Squid?

Mari is a consummate professional who’s on top of her SEO game and she clearly puts in the effort to research a topic well, often going above and beyond expectations. Her articles alone have added several hundred new keywords to my site that rank quickly and become the topical authority in Google. But more importantly, it’s rare to find a writer that I don’t have to edit heavily, and Mari is exactly that! Her style and voice are easy to follow and a pleasure to read.

In this new era where content factories and AI programs churn out unoriginal, inaccurate, or otherwise terribly written articles, Mari is a breath of fresh air!
