In practice
The honest comparison starts with what the work actually requires: a strategy (which pages, which gaps), a prospecting engine (a maintained, qualified publisher list), craft (drafting that publishers accept), negotiation (prices, positions, anchors), and operations (approvals, monitoring, replacement). In-house teams own all of it and keep the compounding assets — the publisher relationships, the campaign memory, the qualification instincts — but pay for them in ramp time: a new in-house hire in a new niche starts cold on every relationship, and the first year buys the learning curve.
Agencies sell the accumulated version: existing relationships in the niche, working process, monitoring infrastructure — the reason a specialist can deliver in month one what an in-house team reaches in month twelve — with the risks being fit (a generalist agency starts from zero in your category) and ownership (relationships that leave with the vendor, reporting that hides the chain). The decision heuristics: volume and duration — a sustained programme in a specialist niche favours an agency with that niche’s publisher graph; a small, strategic burst favours consulting plus in-house execution.
Hybrid is the common adult answer: agency delivers placements and monitoring while in-house owns strategy, approvals and the brand voice — with the contract requiring the transparency that makes the split work: every placement traceable to a URL, fees disclosed, and the publisher list visible to the client. What does not work: buying “links per month” from whoever is cheapest, in-house or agency — the failure mode is identical in both.
