Backlink purchase: what really happens when you buy links

TL;DR

• A backlink purchase is any link you pay for that passes ranking credit. Google’s spam policies class that as link spam unless the link carries a rel="sponsored" or rel="nofollow" tag, which removes the exact thing you paid for.
• Since the December 2022 link spam update, Google’s stated approach is to neutralise bought links, not just penalise sites. So the likely outcome isn’t a dramatic penalty. It’s that you spent money and nothing moved.
• Bought links cost real money. Ahrefs’ outreach study found niche edits averaging $361.44 a link, with paid guest posts at $77.80.
• In the UK there’s a second problem nobody mentions: undisclosed paid content sits inside consumer protection law, not just Google’s rulebook.
• The slower route (local sponsorships, supplier pages, trade bodies, content people actually cite) is cheaper, compounds, and never needs cleaning up.

Don’t make a backlink purchase. That’s the honest answer, and I’d rather hand it to you in the first line than make you scroll for it.

The reason isn’t moral. It’s that the maths stopped working. You’re paying a real per-link rate for something Google now tries to ignore before it ever counts, and the money is gone whether it works or not.

So this post is the longer version of that answer: what a paid link actually is in Google’s eyes, what happens to it now, what it costs, the UK wrinkle that most guides skip entirely, and the boring thing I’d do instead with the same budget.

What counts as a backlink purchase?

A backlink purchase is any arrangement where money or goods change hands and a link that passes ranking credit comes back. That’s broader than most owners expect.

Google’s spam policies name the obvious version (exchanging money for links) alongside three that catch people out: exchanging goods or services for links, sending someone a free product in return for a write-up with a link, and paying for articles where the ranking credit is the real product.

So the paid “sponsored post” on a regional blog counts. The gifted service in return for a review with a link counts. The monthly “50 links included” package definitely counts.

What doesn’t count is paying for a link that’s honestly labelled. Google is explicit that buying and selling links is a normal part of the web’s advertising economy, and it’s fine as long as the link is qualified with rel=“sponsored” or rel="nofollow".

Read that twice, because it’s the whole trap. The moment the link is labelled properly, it stops passing the ranking credit you were buying. You can have the link or the credit. Not both.

Does Google actually do anything about it?

Yes, and the shape of the response changed in a way that matters more than the penalty stories suggest. Google’s current approach leans on neutralising bad links rather than only punishing the sites that bought them.

The December 2022 link spam update was the point that became public. Google used its SpamBrain system to detect unnatural links and cancel the credit they were passing, and Search Engine Land’s coverage noted the rollout ran 29 days across all languages.

Google’s own 2022 spam report put numbers on how aggressive the detection has become. That’s the context for every rate card you’ll be sent.

What actually happens to a link you bought?

Nothing dramatic, usually. The most common outcome by a distance is that the link sits there looking like an achievement in your reporting spreadsheet while passing zero ranking value.

That’s worse than a penalty in one specific way: you never find out. A manual action arrives with a notification in Search Console and a clear job to do. A neutralised link just quietly does nothing while you keep buying more of them.

There are three outcomes, and they’re not equally likely:

1. The link is ignored. Credit neutralised, money spent, rankings unchanged. This is the base case.
2. The link drags on the site. Patterns of paid links across a small site can pull down the trust signals you were trying to build.
3. A manual action lands. Rarer, and reserved for obvious patterns, but it’s the one that costs weeks to clean up.

I’d plan for outcome one. Most owners plan for outcome three, decide the risk is acceptable, and then never notice that they’re losing anyway.

What does a bought link cost?

More than most owners guess, and the original research on this is worth reading before you sign anything. Ahrefs approached 450 sites in nine competitive niches asking to buy a link on an existing page (a “niche edit”), and found that only 12.6% would sell at all, at an average of $361.44 each.

Paid guest posts came in cheaper at $77.80 on average. A separate survey of 755 link builders by Authority Hacker put the average paid link at $83, with experienced buyers paying substantially more per link than beginners.

Run the arithmetic on those published figures. Ten links at the guest-post end is roughly $780. Ten at the niche-edit end is over $3,600. That’s a serious slice of a small marketing budget, spent on something Google is actively trying to discount.

For most owner-operated businesses in Slough or Farnham Common, that same money spread across a year of local sponsorships and one properly built service page will do more, and it’ll still be working in three years.

Is buying links legal in the UK?

Google’s rules are not the only rules you’re operating under, and this is the part that gets skipped in almost every guide on the subject. Paying for editorial coverage that isn’t disclosed as advertising is a consumer protection issue in the UK.

The CMA’s guidance for brands is blunt that hidden advertising is illegal under UK law, and the responsibility doesn’t sit only with the publisher. If you paid for the placement, you’re part of the arrangement.

The enforcement side got sharper too. Since April 2025 the CMA has been able to act directly under the Digital Markets, Competition and Consumers Act, with fines of up to 10% of turnover for consumer law breaches.

To be honest, I don’t think a plumber buying four blog links is about to be fined. But it’s a bad look for a business that trades on being trustworthy, and “everyone does it” has never been a defence anyone enjoyed making.

The three ways a backlink purchase goes wrong in practice

The first is the vendor problem. You’re buying from someone whose business model is selling links, which means their incentive is volume, and volume is exactly the pattern detection systems are tuned to find.

The second is the footprint problem. Paid link networks reuse the same sites across hundreds of buyers. Your link sits on a page next to a payday loan site and a casino, and the relevance signal you were paying for isn’t there.

The third is the ratchet. Bought links don’t compound. Earned links keep paying you back every year; bought ones stop the month you stop paying, so you’re renting rankings on a lease you can never exit. I’ve watched owners spend three years on that treadmill and end up back where they started, minus the budget.

What I’d do with the same budget instead

Here’s what I’d actually do, in order, for a UK service business with a modest annual budget for getting known:

1. Claim the free stuff first. Trade body memberships, supplier “where to buy” pages, your accreditation bodies, your local chamber. These are real links you’re already entitled to and most businesses have never asked for.
2. Sponsor something local and small. A junior football kit, a village fete, a school programme. A modest cheque, a page on a genuinely local site, and a story your customers actually care about.
3. Give the local press something to write about. Not a press release about your rebrand. A real thing: a hire, an expansion, a piece of data about your town.
4. Write the one page nobody else in your town has written. The honest cost breakdown, the regulations page, the “what actually happens on the day” walkthrough. Those get linked to without being asked.
5. Fix what the links would point at. A link to a slow, thin service page is a wasted link.

This is the approach I ran at CoLaz. We took the group from one clinic to nine between 2016 and 2022 on SEO and conversion-built websites, with almost no paid advertising, and every new location got its own local link work rather than a bulk link package.

The lesson worth lifting out of that: location-by-location link work compounds, it doesn’t spike. Year one looks like nothing is happening. Year three is where the curve bends, and by then a competitor can’t buy their way past you. That’s the honest trade you’re making, and it’s the same trade I talk through in any local SEO engagement.

What if you’ve already bought links?

Don’t panic, and don’t rush into the disavow tool. Start by checking the manual actions report in Search Console, because that tells you whether Google has taken action or is simply ignoring the links.

If there’s no manual action, the usual answer is to stop buying, let the neutralised links sit there doing nothing, and put the budget into earned links instead. Google is clear that most sites will never need the disavow tool, and that using it carelessly can hurt you.

If there is a manual action, the path is defined: get the links removed where you can, disavow what you can’t, then submit a reconsideration request with documentation of what you tried. Google’s guidance on the manual actions report notes that link-related reviews often take longer than other types, so give it weeks, not days.

Keep the evidence. Invoices, emails, the list of URLs. A reconsideration request that shows real effort gets a better hearing than one that asserts good intentions.

Is any kind of paid placement fine?

Yes, as long as you’re honest about what you’re buying. Paid placement bought for the audience, tagged with rel="sponsored", is advertising, and advertising is completely allowed.

The mental shift is small but total. Ask “would I still buy this placement if the link passed no ranking value at all?” If the answer is yes, because that publication reaches the people who hire you, buy it. If the answer is no, you weren’t buying advertising, you were buying a ranking, and that’s the thing that no longer works.

Sponsorships, directory listings in real trade directories, local event programmes, industry association profiles: all fine, all worth doing, none of them dependent on hiding what they are.

Where I’d start this week

Pick one: list every trade body, supplier and association you already pay for, and check whether each of them links to you. Most businesses find two or three free links sitting there unclaimed.

Then look at what those links would land on. If the service page is slow, thin, or missing the schema that tells Google what you do, that’s the fix worth more, and it’s the sort of thing I’d sequence first in SEO consulting work. There’s more on the operator background behind that view on my about page.

If you want me to look at your specific site and tell you what’s actually holding it back, book a call. Twenty minutes, no pitch, and I’ll give you a straight answer.
