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 simply wastes money slowly.
Short answer on which to choose: 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.
The cost question, looked at properly
Cost is where surface comparisons mislead. The agency retainer is visible; the full in-house cost is spread across salary, employer overhead, research and outreach 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, not one invoice against one salary.
What an agency actually buys you
The relationships and the process are the product. You are paying for the fact that someone already knows which journalists cover your sector and how to build a story they will run, rather than funding a new hire to learn that on your budget over many months. An agency makes sense when speed matters, when you do not 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 transferred through onboarding rather than being instinctive.
What an in-house team actually buys 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 rather than an invoice. The cost is real and 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, not to save 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 cannot easily scale a single salaried person across more campaigns when you need a push, or wind them down when you do not. If your link building needs come in waves, the fixed cost of a team works against you. If it is a steady, year-round drumbeat at high volume, the team finally has enough to do.
The hybrid that usually works best
Most brands land somewhere in the middle, and that is the right place to be. Keep the things only you can do in-house: brand knowledge, sign-off, and deciding which pages need authority. Hand the specialist execution to an agency: story angles, journalist outreach and placement. You hold strategy and approvals while someone with existing relationships does the part that takes years to learn, and your in-house side gets sharper just by watching how the campaigns are run. It is the setup that gives you control where it matters and specialist delivery where it counts.

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 outreach tools, content support, management time and cover for absence. A managed retainer can be more economical when the workload would not 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 is often the strongest setup. Keep brand knowledge, approvals and target-page decisions in-house, and hand campaign design, journalist outreach and delivery to an agency. You keep control where it matters and get specialist execution where it counts.
What should I look for in a link building agency?
Look for editorially justified placements rather than bought inventory, no rentals or link networks, clear reporting, transparent terms and honesty about publisher control. Avoid agencies promising guaranteed dofollow links or fixed rankings on demand.
When is in-house genuinely the better choice?
When link building is a permanent, high-volume part of your strategy and you can keep a specialist genuinely 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.
