The choice between a link building agency and an in-house function is really a choice about what you want to own. An agency gives you process, tools and publisher relationships from the first week. Building in-house gives you brand knowledge, full control and, eventually, a capability that is yours to keep. Both can work. The wrong one for your situation wastes money slowly.
An agency is often the faster route when you need specialist capacity without hiring a full team. In-house can make sense when the workload is sustained, the brand needs close control and you want to own the capability for the long term. For many brands the practical answer is a blend of the two.
Comparing the full cost
Cost is where surface comparisons mislead. The agency retainer is visible; the full in-house cost is spread across salary, employer overhead, research and media-database tools, editorial support, management time and recruitment risk. One person may not cover research, content, pitching, follow-up and reporting at the volume you expect. Compare like for like: the same output, quality checks and management burden over a full year. One invoice against one salary tells you little.
What an agency gives you
The relationships and the process are the product. You're paying for the fact that someone already knows which journalists cover your sector and how to build a story they'll run, so a new hire doesn't have to learn that on your budget over many months. An agency makes sense when speed matters, when you don't have a strong in-house pitcher, or when you need campaign volume without committing to headcount. The trade-off is shared control: you brief, they deliver, and the brand knowledge has to be passed on through onboarding.
What an in-house team gives you
In-house earns its place when link building is a permanent, high-volume part of your strategy. The team understands the brand instinctively, approvals are fast, target-page decisions happen in the same room, and over time the capability becomes an asset you own. The cost is front-loaded: salary, tools, and the patience to let someone develop relationships before their results match an established agency. Build in-house for control and long-term ownership. It rarely saves money in year one.
| Factor | Agency | In-house |
|---|---|---|
| Speed to first results | Fast; relationships and process exist already | Slow; months to hire, train and ramp up |
| Cost model | Per campaign or monthly retainer, no fixed headcount | Salary plus tools plus overhead, fixed whether busy or not |
| Control | Shared; you brief, they execute | Full; every decision stays inside |
| Brand knowledge | Learned through onboarding | Built in and instinctive |
| Scalability | Flexed up or down by budget | Limited by team capacity; idle when volume dips |
| Best for | Most brands, and anyone needing volume soon | High, sustained volume with a long-term commitment |
Speed and scalability
The two trade-offs people underrate are speed and the ability to flex. An agency can start pitching in week one and turn capacity up or down as your budget moves. An in-house team is slower to start, because relationships take time, and harder to flex, because you can't easily scale a single salaried person across more campaigns when you need a push, or wind them down when you don't. If your link building needs come in waves, the fixed cost of a team works against you. If it's a steady, year-round programme at high volume, the team has enough to do.
The hybrid that usually works best
Most brands land somewhere in the middle. Keep the things only you can do in-house: brand knowledge and deciding which pages need authority. Hand the specialist work to an agency: story angles, pitching and placement. You hold the strategy while a team with existing journalist relationships does the part that takes years to learn, and your in-house side learns from watching how the campaigns run.

FAQs
Is it cheaper to build links in-house?
It can be at sustained volume, but compare the full cost: salary, employer overhead, research and media-database tools, content support, management time and cover for absence. A managed retainer can be more economical when the workload wouldn't keep a specialist team fully occupied.
How long does it take to build an in-house link function?
Allow for recruitment, onboarding, tool setup, editorial processes and relationship building. An established agency can begin with an existing process and team, while an in-house function gains brand knowledge and control as it matures.
Can I use an agency and an in-house team together?
Yes, and it's often the strongest setup. Keep brand knowledge and target-page decisions in-house, and hand campaign design, pitching through journalist relationships and delivery to an agency.
What should I look for in a link building agency?
Look for editorially justified placements with no bought inventory, rentals or link networks, plus clear reporting, transparent terms and candour about publisher control. Avoid agencies promising guaranteed dofollow links or fixed rankings on demand.
When is in-house the better choice?
When link building is a permanent, high-volume part of your strategy and you can keep a specialist busy. At that scale the fixed cost of a team can beat per-campaign fees, and the institutional knowledge becomes an asset. Below that volume, the team sits idle and the maths stops working.
