Buying backlinks: the rules, publisher eligibility criteria and pricing

This page is for B2B marketing or SEO managers considering buying backlinks who need to decide quickly: should you pay for a link, on which publisher, at what price, and how should you disclose it so it stays defensible? It covers the rules, publisher eligibility criteria and pricing, and complements our link building guide, which sets out the full process from diagnosis to proof. You will find a publisher eligibility grid and the price-per-Trust-Flow-point logic.

Buying backlinks: the rules set by Google

Buying a link is not prohibited; passing it off as a spontaneous recommendation is. Google's rule is simple: a paid link, or one that comes from a partnership, is disclosed with the rel="sponsored" attribute. Its spam policies target link schemes: undisclosed paid links, large-scale exchanges, PBNs, automated links.

Since 2016, Penguin has been part of the core algorithm and runs in real time. Since March 2020, nofollow, sponsored and ugc have been hints rather than directives. The details of each attribute and how to mark it up are in our article on dofollow, nofollow, sponsored and ugc links.

What a link disclosed as sponsored is worth

Disclosing the link does not make it useless. A sponsored link placed on a good publisher brings three distinct things:

• An SEO hint: Google can use it for crawling and ranking, without committing to it.
• A brand mention: ChatGPT, Perplexity, Gemini and AI Overviews cite sources, and being named counts in these answers, with or without a link.
• Referral traffic: an article that is read on a media site in your sector sends qualified visitors.

The Incremys doctrine sums this up as "Naming is not linking": the brand mention in the article carries the GEO signal, the link carries the SEO signal, and the two add up.

No purchase is risk-free

The risk comes from detectable patterns, not from paying. It is managed through disclosing the link and choosing the publisher, never through a sales promise. Common structural risks include:

• Editorial footprints: the same article templates, the same anchors, the same "partners" blocks.
• Saturated inventories: a site that sells many links dilutes the authority it passes and looks like a catalogue.
• Site networks: they can work for a while, but become a risk as soon as their shared footprint is visible.
• Pages with no value: a non-indexed source page passes nothing, whatever price you paid.

To place buying among prohibited, acceptable and recommended practices, see the grid in our article on backlink strategy.

Paid formats: what you are really buying

Publishers range from generalist media sites to topical blogs and niche sites. The format matters as much as the publisher, because it sets what you control:

Sponsored article or insertion: choose according to the page

The sponsored article remains the clearest format: the link sits in a text written for the target intent, with an anchor you can vary. An insertion is mainly worth it when the page is already indexed, visited and aligned with your topic. In both cases, the transaction is traceable: the sponsored disclosure is not optional.

As for the buying model, a single purchase lets you test a publisher, a monthly package spreads the cadence; a pack calls for caution (scattered topics, barely visible pages). Before you pay, ask for the domain, the page, the anchor, the attribute and how long the link will stay live.

Publisher eligibility: what rules a site out before any calculation

Before comparing prices, filter. A publisher that fails on any one of these criteria comes off the list, whatever its displayed authority. The grid below sets out what is ruled out and why:

Check the page before you pay

An eligible publisher does not guarantee a good page. Before ordering, check at minimum:

• the page hosting the link is indexed and has a chance to be read;
• the link will sit within the body content, ideally in the first third;
• the page is not stacked with outbound links or "partners" blocks;
• the site ranks for genuine topics, not only for sponsored content;
• the link would still make sense to the reader if Google did not exist.

The media site's constraints (length, client links, external links, anchor, writer) can also be known before buying. They feed into the brief, detailed in our article on running a netlinking campaign.

Attractiveness and price: pay for the Trust Flow point, not the link

Trust Flow drives the price, but value for money is what decides: it is measured as price per Trust Flow point. To rank eligible publishers, the Incremys doctrine uses five criteria:

• The Trust Flow gap with yours: +5 to +15 points is very good; above that, even better; below your own Trust Flow, the value is low.
• Shared topics: the publisher's Topical Trust Flow must overlap with yours; it is not measured as a points gap.
• Traffic trend over 24 months: growth, stability or decline.
• Existing link: a site that already links to you does not bring a new referring domain.
• GEO performance: a "GEO gem" is a domain very often cited by ChatGPT; a "cited" publisher is cited sometimes.

The publisher's TF/CF profile completes the picture: a Trust Flow / Citation Flow ratio below 0.55 signals volume without trust. The definition of these metrics and how to read the ratio are in our article on backlinks and their quality.

Price benchmarks and what they help you decide

Prices are too dispersed for a price grid. The average price of a backlink is $361 (SEO.com, 2026). This average helps you estimate the volume a budget allows, not buy "at the average price".

On the service side, the median budget for an engagement that includes link building is €4,000 excl. VAT (La Fabrique du Net, 2026). The link building share cannot be isolated: this benchmark sizes an engagement, not a link. Other benchmarks are in our SEO statistics.

A fixed budget: one link, ten links or a hundred links

With the same budget, three extreme allocations illustrate the trade-off between concentration and volume:

The right answer depends on your constraints. A pragmatic allocation combines three blocks, each with its own goal:

• Core: publishers above your Trust Flow, for traction.
• Support: sites tightly aligned with your topics, for relevance and traffic.
• Diversification: a few different formats and page types, to avoid a monolithic profile.

What makes a link "premium", and what does not justify it

"Premium" is not a label: a link earns the name when it combines a Trust Flow clearly higher than yours, an aligned topic and a genuine editorial context. What justifies the price, and what is only a sales pitch:

When an expensive link becomes rational

Paying more is justified if the domain is clearly above your authority, the context is credible, the page will be read and a guarantee covers the link's lifespan. Such a link can be worth several weak links on a highly competitive query.

Conversely, quantity becomes a trap as soon as it pushes you to accept compromises:

• non-indexed or barely visible pages;
• footer, sidebar or sitewide links;
• pages loaded with outbound links;
• optimised anchors repeated from one publisher to the next.

Link exchange: disclosed partnerships yes, systematic reciprocity no

An exchange means getting an inbound link from a partner in return for an outbound link to them. Even without money, it is still a transaction: large-scale exchanges are among the link schemes targeted by Google's spam policies.

Reciprocal, triangular, partnership: four set-ups

Common set-ups do not have the same status:

• Direct reciprocal (A links to B, B links to A): easy to negotiate, easy to spot once it repeats; it is a scheme.
• Triangular (A to B, B to C, C to A): it reduces visible symmetry without removing the scheme.
• Chains and credit-based platforms: publish to earn credits, spend them to get a link; footprints multiply.
• Disclosed editorial partnership: joint study, cross-interview, co-signed guide; acceptable when the link serves the reader and carries the sponsored attribute.

The line comes down to intent. A legitimate partnership connects clients, suppliers or a real ecosystem, and produces content that would have existed without the link. As soon as the aim is to manufacture signals (repeated anchors, "partners" pages filled with links), you are in scheme territory.

Who writes, and what the guarantee covers

A paid link involves two decisions to make at the time of ordering: who writes the article, and who answers for the link once it is published.

Who writes the sponsored article

Depending on the offer, the article is written by Incremys (Content Factory, a network of vetted writers) or by the media site. The brief sets the keyword, the intent, the topics, the questions, the semantic field and the publisher's constraints. When the media site writes, check that your brand is named correctly: it carries the GEO signal.

The 24-month guarantee

A guarantee covers a duration, a proof and a status. On the Incremys platform, links bought are guaranteed for 24 months: their presence is checked and reporting shows the status of each guarantee, active or expired. This guarantee does not apply to links imported from another provider, but those campaigns can be imported to be tracked in the same place.

After each publication, the check covers four points:

• the link is present in the planned location;
• the attribute matches the transaction;
• the anchor is the one in the brief;
• the source page is indexed.

Measuring what the purchase changed

A link's return is judged page by page, each page compared with itself before its first link and today. Incremys reporting tracks link presence (live, lost, unverified), the domain's Trust Flow, the anchor text profile, keyword rankings and the ChatGPT citations gained or lost per question.

The reading remains a time correlation, never causation: reporting does not state that a link produced a citation. Document what blurs the measurement: Google updates, page redesigns, internal linking changes, seasonality. The financial calculation stays classic: gains minus costs, divided by costs.

Depending on your situation

Depending on where you are, the next step is here:

• You are comparing platforms: apply the criteria for choosing a netlinking platform, from a deduplicated catalogue to the guarantee.
• You would rather get links without paying: compare the methods to get backlinks by effort, timeframe and risk.
• You are delegating the buying: check what the contract for a netlinking service must include.
• Your priority is being cited by AI: see how links and mentions count for generative engines.

To choose your publishers without comparing resellers, the Incremys Offsite media module shows, at the time of writing, a catalogue deduplicated by domain with each publisher's Trust Flow, topics, 24-month traffic, GEO performance and price per Trust Flow point. Links bought through the platform are guaranteed for 24 months, with their status tracked in reporting.

FAQ on buying backlinks

Is it legal to buy backlinks?

Yes, buying a backlink is allowed provided you disclose it. Google asks that a paid link, or one that comes from a partnership, carries the rel="sponsored" attribute. Undisclosed buying falls within the link schemes targeted by its spam policies, as do large-scale exchanges.

How much does a backlink cost?

The average price of a backlink is $361 (SEO.com, 2026), with very wide dispersion across publishers. It is mainly the domain's Trust Flow that sets the price. To compare two offers, divide the price by Trust Flow points, then look at topics, traffic and GEO performance.

Does a sponsored link have an SEO effect?

A sponsored link remains a hint that Google can use for crawling and ranking, without committing to it. Since March 2020, nofollow, sponsored and ugc have been hints rather than directives. The link also brings a brand mention that is useful for generative engines, and referral traffic when the article is read.

What is a premium backlink?

A premium backlink combines a Trust Flow clearly higher than yours, an aligned topic and a genuine editorial context. It is not a commercial label: a "premium pack" delivered in volume, or a displayed Domain Authority or "PR9", does not justify a price. The publisher's GEO performance, on the other hand, can add value.

Is link exchange risky?

Simple reciprocal exchange is risky, because large-scale exchanges are among the link schemes Google targets. Triangular or credit-based set-ups reduce symmetry without removing the scheme. A disclosed editorial partnership, such as a joint study or a co-signed guide, remains acceptable if it serves the reader.

What does a guarantee on a bought link cover?

A serious guarantee covers a duration, a presence check and a clear status. On the Incremys platform, links bought are guaranteed for 24 months, their presence is checked and reporting shows whether the guarantee is active or expired. A guarantee of less than 24 months is enough to rule out a publisher.

Who writes the sponsored article?

Depending on the offer, the article is written by Incremys, through the Content Factory and its network of vetted writers, or by the media site itself. The brief sets the keyword, the intent, the topics and the publisher's constraints. If the media site writes, check that your brand is named correctly, because the mention carries the GEO signal.

How do you check a link after publication?

After publication, check that the link is present in the planned location, that its attribute matches the transaction, that the anchor is the one in the brief and that the source page is indexed. Then keep tracking its presence: a lost link no longer passes anything.
