Link building services: what they sell, how they price and the risks

At a glance

• A link building service is a company that places links to your site on other people’s websites for a fee, usually sold per link or as a monthly retainer.
• Outreach, digital PR, guest posts, niche edits and PBN links are different ways of getting the same deliverable: a link on a site you don’t control.
• Google’s spam policies count “buying or selling links for ranking purposes” as link spam, and calling the service “white hat” doesn’t change that.
• The main risks are host sites that sell to everyone, metrics inflated without real traffic, links that vanish after you pay, and no say over anchor text or timing.
• The alternative is to build links on sites you own, which costs more time and money up front but keeps control with you.

What a link building service is

How the links are obtained decides how long they last and how much risk you take on, and the sellers rarely spell it out. We have hosted private blog networks since 2014, so our view comes from the other side of the market: the people who own the sites the links sit on.

How link building services get links

Every service runs one or more of the methods below.

Service type	What you get	How much control you keep	Main risk
Blogger outreach and digital PR	Links from sites that agreed to mention you	Low: the site owner picks anchor and context	Slow, and many “outreach” links are quietly paid
Guest posting	An article with your link on someone else’s blog	Some: you can suggest the topic and anchor	The same sites accept posts from anyone who pays
Niche edits (link insertions)	Your link added to an existing article	Low	The site sells insertions to all comers
PBN link sellers	Links from a network sold publicly	Low	Public networks are easy to find and penalize
Broken link building and reclamation	Dead links swapped for links to your page	Low	Slow and limited by what exists
Journalist-request platforms	A quote and sometimes a link in an article	None	Links are rare and often nofollow
White-label link building	Any of the above, rebranded for agencies	None for the end client	You can’t see where the links come from

Blogger outreach and digital PR

The service emails site owners in your niche and asks for a link, usually to content made for the purpose, such as a study or a data page. Digital PR does the same with news sites and a story a journalist might cover. Many outreach campaigns end with the site owner asking for a fee, so “outreach” on an invoice often means a paid placement found by email. Either way, the site owner decides the anchor text, the surrounding sentence and whether the link stays.

Guest posting services

The service writes an article and places it on a blog that accepts contributions, with a link to you inside. You can usually suggest a topic and an anchor. But a blog that publishes paid guest posts for you publishes them for everyone, and its outbound links show it. Guest posting gets its own guide, which we are publishing separately.

Niche edits and link insertions

Instead of a new article, the service pays to have your link added to an article that already exists and already has some age and links of its own. Sellers pitch the page’s age as the selling point. The same problem applies: the site sells to many customers. Niche edits also get their own guide.

PBN link sellers

Some services sell links from networks of blogs built on expired domains. Our PBN guide is blunt about this: “The P in PBNs stands for ‘private’ and not ‘public’ blog networks. If anyone can buy a link, those are coming from public blog networks.” A network that sells to anyone links out to everyone, which is how networks get found. See what buying PBN links costs and why we advise against it.

Broken link building and link reclamation

The service finds dead links on other sites, offers your page as the replacement, and chases unlinked mentions of your brand. These links are the closest thing to earned, because the service sells labor rather than placements. Volume is limited by how many broken links and mentions exist in your niche.

Journalist-request platforms

HARO (Help a Reporter Out) matched journalists with experts willing to give quotes. HARO no longer operates, and other platforms fill the same role. A chosen quote never “automatically” earned a backlink: journalists decide whether to link, and many publications don’t link or use nofollow. Treat any service built on these platforms as PR with an occasional link.

White-label link building

White-label providers do any of the above for agencies, which resell the links under their own brand. The end client may not know which sites the links come from at all.

How link building services price their work

Three pricing models cover almost everything you will see:

• Per link is the most common model. Prices are tiered by the host site’s metrics, typically Ahrefs Domain Rating or estimated traffic, so a link on a “DR 50” site costs more than one on a “DR 20” site.
• A monthly retainer is a fixed fee for a target number of links per month, sometimes bundled with content writing and reporting.
• Per campaign pricing is how digital PR agencies work: they price a campaign (the story, the pitching, the coverage) rather than individual links, because they can’t promise how many links a story will earn.

Pricing by metric gives sellers a reason to inflate the metric, which can rise without the site gaining a single reader. For the numbers behind each model, see what link building costs.

The risks nobody on page one mentions

It is still buying links. Google’s spam policies define link spam as “the practice of creating links to or from a site primarily for the purpose of manipulating search rankings”, and the first example listed is “Buying or selling links for ranking purposes” (developers.google.com, fetched 2026-10-28). A service calling itself white hat doesn’t move its product out of that list. Our own position is that every link building tactic, outreach and guest posts included, runs against Google’s guidelines, and that those guidelines serve Google. But if you pay a service so you can stay “safe”, know that you aren’t.

The same sites serve every customer. A site that sells links to you sells them to hundreds of others. Its outbound links point at unrelated commercial sites across every niche. Our PBN guide names the outbound link pattern as one of the two most harmful footprints, and a link-selling site has that pattern by design.

Metrics get gamed. Host sites are often built to look strong on paper: high Domain Rating, little organic traffic, and pages that exist only to hold links. Check traffic separately.

Links disappear. Sites get deindexed, sold, redesigned or cleaned up, and the link goes with them. Some services replace lost links for a period. Many don’t, and few will tell you when it happens.

You don’t control anchor, context or timing. The host site picks the words around your link, the article it sits in and when it goes live. Those are the signals that make a link work.

If you hire one anyway: a vetting checklist

These checks filter out the worst offers:

• Ask for live sample placements and read the articles the links sit in. A list of domains tells you nothing.
• Check each host site’s organic traffic and trend in Ahrefs or Semrush. Steady or growing traffic is a good sign. A high rating with no traffic means the site exists to sell links.
• Look at each site’s outbound links. If it links to casinos, supplements, loans and a plumber in one week, it sells to anyone. Our guide on how to check the backlinks of a website shows how.
• Skip sites that advertise “write for us” or “sponsored posts accepted” to the public. Anyone can find those pages, including Google.
• Ask what happens when a link disappears, and get the replacement policy in writing with a time period.
• Ask which methods they use. If the answer is “a mix of white hat strategies”, ask again.

The alternative: build links on sites you own

Every service type above shares one weakness: the link lives on someone else’s site. A private blog network is a group of blogs you control, usually built on expired domains that still have links pointing to them. Our PBN guide puts the reason simply: “The ultimate goal is to have control over link-building efforts for your money sites. The alternative is to rely on other webmasters to editorially place backlinks on their sites, which are outside of your control.” With your own sites, you choose the anchor text, the topical relevance of the page and when the link goes live. Nobody else is buying from the same site.

The honest drawback is cost up front: domains, hosting, content and weeks of waiting before you link. The guide calls PBNs “a great alternative to just about every other link-building tactic” and names the main drawback in the same breath: “the high upfront investment in time and money.” If you are deciding between the two routes, our comparison of a PBN or a link building service goes through the trade-offs, and the guide to build your own PBN covers the steps.

FAQ

Are link building services worth it?

Sometimes, for a short push or when you have no time to build anything yourself. You are renting links, so the value lasts only as long as the site and the link do. Compare a year of retainer fees with what the same money buys in domains and hosting for sites you keep.

Are link building services safe?

No link building method is free of risk under Google’s policies, and paid placements on sites that sell to everyone are among the easiest to spot. The checklist above reduces the risk. It doesn’t remove it.

Is buying links illegal?

No. Buying links isn’t against the law. It is against Google’s spam policies, and the penalty is lost rankings. For more on whether you need to pay at all, see do you have to buy backlinks.

What is the difference between a link building service and an SEO agency?

An SEO agency usually covers technical fixes, content and reporting, and may or may not build links. A link building service does only links. Many SEO agencies outsource their link building to white-label providers, so you can end up buying from the same source through a middleman.
