A partner, not a commodity link seller
Zadix started as hands-on manual outreach — not a script matching keywords against a spreadsheet of domains for sale.
Most of the backlink market runs on inventory: a fixed list of domains at fixed prices, regardless of whether a domain actually fits your niche. That model is fast, but it treats links as interchangeable units instead of placements that need to make sense in context.
We source per brief instead. When you send us a target URL and niche, we look for a publisher that actually fits it — then check that publisher against the same criteria every time: real organic traffic, checked domain authority, and a clean outbound link profile.
That's slower than pulling from a pre-built list, and it means we say no to some domains you might see offered elsewhere. It's also why agencies use us to fulfill work they're putting their own name on.
What we hold to
No commodity link selling
We don't run a marketplace of pre-listed domains at fixed prices. Every placement is sourced for the specific brief.
Manual quality control
There's no script deciding which domains qualify. A person checks traffic, authority, and spam score on every candidate site.
Transparent reporting
You get the live URL and the metrics behind it — not a vague confirmation that 'the link is live somewhere.'
How we check a domain
Organic traffic
Every candidate domain is checked for genuine organic search traffic in Ahrefs or Semrush — not just a domain rating number.
Domain authority
We check domain rating/authority alongside traffic, since either metric alone can be manipulated.
Spam score
Domains with elevated spam signals or a history of link-scheme penalties are excluded.
Real editorial operation
We confirm there's an actual publication behind the domain — a real editor, real other content, a real audience.
Outbound link profile
We check what else the site links out to. A page surrounded by casino, pharma, or essay-mill links gets rejected.
Topical relevance
The placement has to make sense in context — your link sits in content related to your niche, not bolted on.
