Six ways our AI marketplace beats a traditional link building agency
Most link building marketplaces are a directory of publishers with a checkout. Ours adds a full Claude-powered intelligence layer that does the strategy work an agency used to charge you for.
AI publisher matching
Drop a target keyword or competitor URL. Claude analyzes your topical fit against 10,000+ publishers and surfaces the placements most likely to move your rankings, not just the ones with the highest DA.
AI content brief generator
Every order auto-generates a writing brief based on the host site's editorial style, your target keyword's intent, and the structure of competing top-ranked content. The brief is yours to edit before approval.
Ranking impact forecast
Before you spend, see an estimated ranking lift based on your current position, the link's authority profile, and the historical lift our publishers have delivered for similar campaigns.
Niche relevance scoring
Every publisher in the marketplace is scored against your niche by a model that reads the publisher's recent content. Stop paying for high-DA links that have no topical relationship to your site.
AI quality & detector check
Every article is run through Originality.ai and a Claude QA pass for tone, structure, and brand fit before it reaches the publisher's inbox. Rejection rates drop, placements stick.
AI campaign roadmap
For ongoing campaigns, the system generates a monthly placement plan based on your target queries, current rankings, and competitor link velocity. You approve, we execute.
