Link building cost
Link building cost is what it takes to acquire a link, and it depends far more on how the link is acquired than on the link itself: an earned link costs the time, tools and content behind the outreach that won it, while a bought placement has a sticker price - which Google's policies say must be marked sponsored, so it passes no ranking credit.
Also called: how much does link building cost, link building pricing, cost per backlink, backlink prices
Most published "cost per link" figures measure the second thing. They come from asking sites what they charge to publish a link, or from marketplaces that sell guest posts, and they are real prices for real transactions. They are not the cost of the links search engines are trying to reward, because those links are by definition not for sale.
The cost of earning links is harder to quote because it is mostly labor. Prospecting, writing personal emails, following up, answering journalists and building something worth citing all take hours, and the number of links those hours produce varies enormously with the site, the subject and the quality of the asset being promoted.
That is why two honest answers to "how much does link building cost?" can differ by an order of magnitude, and why the most useful number for any program is its own: total spend divided by the live, relevant referring domains it actually produced.
What published link prices show
Two data sets are cited more than any others, and both measure the price of a paid placement:
- Ahrefs' outreach experiment. Ahrefs reports asking 450 sites across nine competitive niches to sell a link outright; the 12.6% willing to sell asked $361.44 on average. A parallel pitch for unpaid guest posts to 180 sites drew fee requests from about half of those who replied, averaging $77.80.
- BuzzStream's guest post pricing study. BuzzStream analyzed listed prices for about 257,000 sites on a large link marketplace (updated June 2026) and found guest posts averaged $295 when bought directly from a site and $461 through a vendor, with prices rising steeply for sites with stronger metrics and top-tier news sites costing thousands.
What earned links actually cost
An earned link has no invoice, so its cost has to be built up from what the program spends:
- Time. Research, prospecting, writing, follow-ups and reply handling, whether that is your own hours, an employee's, or a freelancer's. Usually the largest cost by far.
- Tools. Backlink data, contact finding, outreach software and monitoring, typically billed monthly.
- Something worth linking to. Original research, a useful tool or a definitive guide. It costs money to make, but it is what turns outreach from asking into offering.
- Expert time. For digital PR, the subject-matter expert who answers journalists - often a founder whose hour is expensive.
How agencies and services price link building
- Per link. A fixed price for each placement, usually tiered by the linking site's metrics. Simple to buy, but a fixed price per link with a promised metric usually means the links are paid placements, whatever the sales page calls them.
- Monthly retainer. A fixed monthly fee for ongoing outreach, with an estimate rather than a promise of links. Closer to how earned links actually behave.
- Per campaign. Common in digital PR: a fee to create and pitch one data study or creative campaign, with results that vary widely.
- Software you run yourself. Outreach tools and AI outreach products charge a subscription, and the links depend on how well the program is run.
How to budget for link building
Start from capacity rather than a link target: decide how many hours or how much monthly spend the program gets, run it for a few months, and measure what it produced in live, relevant referring domains. That gives you a real cost per link for your own site and subject, which is worth more than any industry average.
Judge the result by the links' quality, not their count. Ten links from publications your buyers read are worth more than a hundred from sites that exist to sell links, and the cheap option is often the one that costs the most once the links are ignored or have to be cleaned up.
Common questions
How much does link building cost per month?
There is no standard figure, because programs range from a few hours of your own time to agency retainers costing thousands a month. The useful way to answer it for your site is to fix a monthly budget, run it for a quarter, and divide what you spent by the live, relevant referring domains it produced.
Why do backlink prices vary so much?
Published prices mostly reflect the selling site's metrics and traffic, the niche, and whether a reseller sits in between - BuzzStream's 2026 study found vendor prices averaged roughly 56% above buying direct. Earned links vary for a different reason: the cost is labor, and how many links a given amount of work produces depends on the asset and the subject.
Are cheap backlinks worth buying?
Rarely. Links sold cheaply in bulk usually come from sites that exist to sell links, which Google is good at ignoring, and buying links for ranking credit without marking them sponsored violates its link spam policy. The money is usually better spent on something worth citing and the outreach to tell people about it.

Link building
Link building is the practice of getting other websites to link to yours, because search engines treat a link from one site to another as a signal that the destination is worth showing to searchers.
Google link spam policy
Google's link spam policy is the published section of its search spam policies defining link practices Google considers manipulative - buying or selling links for ranking purposes, excessive link exchanges, large-scale automated link building, and requiring links as a condition of an agreement.
Link building outreach
Link building outreach (often just "link outreach") is contacting the people who run other websites - editors, writers, site owners, journalists - to give them a genuine reason to link to your content. It is how most deliberately earned links begin, and it succeeds or fails on relevance rather than volume.
Digital PR
Digital PR is public relations run with search visibility as an explicit goal: earning coverage, citations, and links in online publications rather than pursuing print or broadcast placement for brand awareness alone. When the aim is specifically the links, it is usually called PR link building.
Niche edits
A niche edit is a link added to an article that has already been published, rather than to new content. The term covers two very different things - asking a site owner to add a genuinely useful link to an existing page, and paying a site to insert one - and only the first is consistent with Google's link spam policy.
