Guest Post Guidelines — Write for Giobel Koi Center
We welcome original, high-quality guest posts on koi fish, ponds, and aquatic lifestyle — and select unrelated niches where your article genuinely connects with our audience. Read the full guidelines before submitting.

We accept guest posts on koi fish, ponds, aquariums, and aquatic lifestyle — and we also accept posts from unrelated niches, provided the article is written to genuinely connect with our audience and your backlink fits naturally within the content. Low-quality posts, pure link-placement articles, and off-topic promotions are rejected. Fee is $30–$50 depending on topic type.
About Giobel Koi Center
Giobel Koi Center is one of the Philippines’ most established koi fish resources, run by Giovanni Carlo — a koi specialist with over 30 years of hands-on breeding and keeping experience. Our readers are koi hobbyists, pond builders, aquarium enthusiasts, and people interested in the spiritual and cultural meaning of koi fish, based primarily in the Philippines, US, UK, and Australia.
We publish content that helps our audience keep healthier koi, build better ponds, and understand the cultural significance of their fish. Every guest post we accept must add genuine value to that audience — regardless of the author’s niche.

Unrelated Niches — The Blending Rule
We understand that link building often requires placing content outside your exact niche. We accept guest posts from unrelated niches — but with a strict standard that protects both our readers and your link’s long-term value.
The article must be written for our audience, not about your product. If you sell home renovation services, don’t send us “Top 10 Home Renovation Tips.” Instead, pitch something like “How to Design a Garden Space Around a Koi Pond” — your link to a relevant page on your site fits naturally, our readers get useful content, and both sides win.
Your backlink must be placed contextually — where it genuinely adds value for a reader who wants to learn more. A forced link with no relevance to the surrounding paragraph will be removed during editorial review without refund.
This is not a loophole — it is a standard. Articles that don’t pass the “would our koi audience actually read this?” test will be rejected regardless of payment.
