Structured editorial collaboration

Authority on the web grows when organizations are referenced by trusted publishers. But earning those references is often messy.

Outreach happens through scattered emails. Terms are unclear. Payments are handled informally. Tracking results is difficult.

404200 provides a platform where brands and publishers can work together in a more structured way.

Campaigns focus on earning citations and references through real editorial collaboration.

Citations

What counts as a citation

A citation can take many forms online.

Expert quotes in articles

Mentions of a brand or company

Product or tool references in guides

Data cited in research content

Resource listings

Interviews or collaborative content

Some citations include links. Others are simply references.

Both help build long-term authority.
