About Koi Content, and why we sell links for slow writing
We run a marketplace of 50,000+ donor domains and write for a particular reader: the one who updates a three-year-old guide and means to keep it alive.

The pond we keep
Koi live for decades. That is the picture behind the name, and the stance of this whole site. We care about articles meant to outlast a news cycle, and about the patience that takes from the person who wrote them.
The shop itself is simple. You browse vetted donors, fill a basket, pay from your balance, and a placement goes live, usually inside about 24 hours. Prices start at $1.
Our data comes from our own crawler and our own index. We describe it that way and no other, because anything fancier would be a guess.
What we do and refuse to do
We show the price before the pitch
Every donor row lists its metrics and its price. No subscription, no minimum.
We say when to wait
Our calendar exists because most disappointment with links is a timing error.
We do not promise rankings
A placement is one signal. Google weighs many, and we cannot see inside its systems.
We tell you when not to buy
If the page is thin, fix it first. Say so out loud, and save the money.
How the backlink marketplace is meant to be used
A backlink marketplace is easy to misuse. Ten minutes fills a basket. It feels like progress, yet we would rather you slow down, so the site is arranged to help you do exactly that.
Start with the one article you would be proud to still have in 2030. Pick it. Find two or three donor sites that a reader of that article might plausibly visit, add one to the basket, pay, and note the date in Search Console.
Then comes the hard bit: waiting. The patience calendar gives you windows, and the glossary explains the words in your reports. After a season, look again at clicks, impressions and position for your chosen query.
Mistakes are cheap here. Placements begin at $1 and reach about $500 for top domains, so a poor test costs little, and a good one tells you where to put the next dollar. See the budget plans for examples.
Who writes this
The pages are signed by the Koi Content editorial team, a group rather than a person on purpose. Questions, corrections and complaints all go through your account page.
Publishers can also sell links from their own sites here: set a price, approve every placement, and receive weekly payouts. If your blog has steady readers, that is another way to keep it funded.

A note for the impatient
If you want a page-one result by next week, we are the wrong shop. Sorry. We would rather lose that order than sell a hope.
Everyone else is welcome to look around. Open the marketplace, read a few donor pages as a visitor would, and come back to our republishing tree if you also plan to post your article elsewhere.
