White-label link building,
built for agencies.
Every publisher domain is manually vetted for real organic traffic, domain authority, and spam score before we pitch it. No PBNs, no expired domains, no link farms.
Drag to rotate
Link building, PR, and content — under one roof
Guest Posting
A full article, written for the host site and placed on a vetted, real-traffic publication, with your link in the body copy.
- A bespoke article written to the host publication's editorial standard
- One in-content, contextual link with the anchor text you specify
Niche Edits
Your link, inserted into an existing article that's already live, indexed, and ranking on Google — no new content, no waiting for a new page to age.
- Insertion into a live, previously indexed article on a vetted domain
- A short passage of new copy written to blend naturally with the existing article
Blogger Outreach
We pitch independent bloggers and niche publications directly — smaller, highly relevant sites that a mass-market vendor list won't include.
- Direct outreach to bloggers and independent publications matched to your niche
- Placement negotiated on a case-by-case basis (guest article or existing content mention)
Manual Outreaching
Custom outreach campaigns built around your own prospect list or a hyper-specific target profile, run by a person, not a mail-merge tool.
- A prospect list built or refined to your exact criteria
- Individually written, personalized pitches — not a templated mail-merge sequence
Digital PR
Story-driven campaigns pitched to journalists and media publications — coverage and links that come from being newsworthy, not from a link order.
- A newsworthy campaign angle developed around your brand or data
- Direct pitching to relevant journalists and media contacts
Press Release Distribution
A professionally written press release, distributed to a vetted network of news and media sites for announcement-driven coverage.
- A press release written to journalistic style, not marketing copy
- Distribution to our vetted news and media site network
Content Writing
Standalone articles and website content, written to a publication-ready standard — with or without a link building campaign attached.
- Articles researched and written to a publication-ready editorial standard
- Content matched to your brand voice and target keyword focus
From brief to live placement in four steps
Share your targets
Send the target URLs, anchor text, and niche or geo requirements — your own, or your client's, depending on how you work.
We source and vet
Our team checks candidate publisher domains for real organic traffic, domain authority, and spam score before anything is proposed to you.
Content or placement
For guest posts and PR, we write and pitch. For niche edits, we find a live, already-ranking page and insert your link into it.
You get reporting
You receive a report with the live URL, domain metrics, and indexing status — branded with your own name if you're reselling.
What we check before pitching a domain
Zadix works with a network of 43,000+ publisher sites across every niche and country. Every one that makes it into a placement is checked against the same criteria.
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.
A report you can hand straight to a client
Every placement comes with the live URL, the publisher's metrics, and confirmation the page is indexed. If you're reselling, the report carries your branding, not ours.
Ask about white-label reportingCampaigns and results
Guest Posting
The agency's client had a strong product but a thin backlink profile on their core pricing and comparison pages, which were stuck outside the top 10 for their main commercial keywords.
Niche Edits
A multi-location law firm needed a faster way to support several location and practice-area pages that were ranking on page 2, without waiting months for new content to age.
Blogger Outreach & Content Writing
A direct-to-consumer brand wanted authentic coverage ahead of a seasonal launch, but their category didn't have enough large publications to sustain a guest-posting-only campaign.

Started as hands-on outreach, not a script
Zadix isn't a marketplace of pre-listed domains. We source placements per brief, vet them by hand, and report on them honestly — treating this as a partnership, not a one-off link sale.
