Decision guide
Agency, marketplace or freelancer — which should you use?
Three routes to the same outcome, with completely different failure modes. The right one depends less on budget than on who is going to enforce quality.

The short answer
Marketplaces are cheapest at $141–$609 per link but you carry all quality risk. Freelancers cost $300–$800 and offer control without scale. Agencies cost $500–$1,250 and rent you publisher relationships. Below $2,000 a month, concentrate spend rather than choosing any of them.
Three routes, three sets of economics, three different things that go wrong.
Side by side
| Marketplace | Freelancer | Agency | |
|---|---|---|---|
| Cost per link | $141–$609 | ~$300–$800 | $500–$1,250 |
| Who vets quality | You | Shared | Them, against criteria you set |
| Scale ceiling | High | Low | High |
| Publisher access | Public inventory | Their personal list | Established relationships |
| Continuity | None needed | Single point of failure | Team cover |
| Main risk | Buying from the 98.6% | Capacity and availability | Paying retainer rates for marketplace quality |
Marketplace and agency figures from Ahrefs, BuzzStream and Siege Media. Freelancer rates are not systematically published; the range shown is the band commonly observed and should be treated as indicative rather than sourced.
Marketplaces
You browse listed sites, filter, and buy placements directly. Cheapest per link and fastest.
The catch is that everything in a marketplace is, by definition, for sale to anyone — including your competitors. And BuzzStream found only 1.37% of guest post opportunities meet quality standards, so the filtering job is enormous and it is entirely yours.
Marketplaces work if you will personally check organic traffic, publishing history and outbound link patterns for every site before buying. If you will not, you are buying inventory and the saving is illusory.
Freelancers
An individual outreach specialist, usually working from relationships they have built personally.
Cheaper than an agency, more selective than a marketplace, and you get direct contact with the person doing the work — which is often the best communication of the three.
The constraints are structural. One person has one publisher list and one calendar. Above roughly five links a month most freelancers are at capacity, and when they are ill or on holiday, output stops. There is also no cover for the relationship ending.
Agencies
You are renting publisher relationships and an outreach operation. That is the whole proposition and it is a real one — a firm with forty clients can justify an outreach team that your budget alone cannot.
The premium is justified when you need volume, when your category is competitive, or when nobody internally will own quality. It is wasted when the agency is quietly sourcing from the same marketplaces you could have used, which is why the vetting process matters — specifically the step where you audit five real placements yourself.
Choosing by budget
- Under $2,000/month — none of the three as a programme. Buy three good links directly, pointed at one page. Spreading this budget achieves nothing measurable.
- $2,000–$5,000 — freelancer or a small agency engagement. Two agencies in our directory operate without a minimum contract, which suits this level.
- $5,000–$10,000 — agency. The band 46.5% of buyers sit in, and the one agencies are built for.
- Over $10,000 — agency plus in-house ownership of strategy and quality control. See in-house vs agency.
Whichever route, the quality floor has to be enforced by someone. The three options differ mainly in who that someone is.
