How to get quality backlinks in B2B: methods that work, methods to avoid

You run SEO or marketing for a B2B company and need to decide how to get quality backlinks that actually move your rankings, without putting your domain at risk. This guide sets out the methods that work, ranked by effort, timeline and risk, shows how to find and score the sites worth contacting, and lists the methods to avoid.

It builds on our guide to netlinking, which covers the full journey: diagnosis, choice of publishers, campaign, proof. Here, the focus stays on earning links and mentions, on Google as well as in the answers of generative engines.

Start with the diagnosis: is a link the right lever?

Most pages receive no inbound links at all: 94–95% of pages have no backlinks (Backlinko, 2026), as our SEO statistics point out. A handful of quality referring domains can therefore set you apart, provided the page deserves to be strengthened.

A URL's link target is the median number of dofollow referring domains held by the top 10 organic results for its keyword; the gap with your page tells you how many domains you are missing. The reference metric is the number of unique dofollow referring domains, not the volume of backlinks.

Do not start with prospecting in the following cases:

• Content first: the page has never performed; a link will not change that until it matches the search intent.
• Another page ranks: Google ranks a different page from your domain; strengthening the wrong URL blurs the signal.
• To defend: you rank above your link weight; protect what you have before looking for more.

The methods below pay off on pages "to strengthen": the content is done and links are the remaining lever. How to read the five states and prioritise URLs is covered in our guide to backlink strategy.

Methods that work: effort, timeline and risk

Durable methods share the same logic: create or identify a genuine editorial reason for another site to cite you. The table compares them by effort, timeline and risk.

Citable content and digital PR

Citable content is an asset that other sites reference without being asked, provided it is truly distinctive. In B2B, the formats that work are:

• Study or barometer: sourced, dated data, with the collection method.
• Benchmark or comparison: explicit criteria and explained scoring.
• Free tool: calculator, generator, interactive template.
• Template or checklist: content brief, audit grid, evaluation matrix.
• Reference guide or glossary: clear definitions that are easy to reuse.

Digital PR starts from the same asset: verifiable data, its method and a useful conclusion for an industry. It produces editorial links and brand mentions. Generative engines cite sources and name brands: for them, a mention counts even without a link. Naming is not linking, and the two signals add up.

Selective guest posts

Guest posting works when the article delivers genuine value to the host site's readers. Choose a tightly focused topic, a single link to a page that goes deeper, and a publisher whose editorial line overlaps with your expertise. Experience reports, process guides and analyses of a market shift earn contextual links; pretext articles do not.

Unlinked mentions, broken links and resource pages

These methods recover value that already exists and require little content creation:

• Unlinked brand mentions: a site cites you without a URL; ask for the link to be added, with a clear justification.
• Lost or misplaced links: wrong URL, unnecessary redirect, link removed during a redesign; ask for a correction.
• Broken link building: spot an outbound link returning a 404 error on a relevant page and offer your resource as a replacement.
• Resource pages: tool lists and libraries in your niche, provided they are indexed and maintained.

For a broken link, your resource must serve the same intent and be more up to date. Reduce effort for the editor: exact URL, exact dead-link location, and a clear suggestion.

Disclosed partnerships and purchases

A partnership with a client or supplier produces stable links if it lives through content (case study, interview, joint study) and does not turn into systematic reciprocity. As soon as there is something in return, the link is disclosed with rel="sponsored": that is Google's rule for a paid link or one resulting from a partnership. Publisher eligibility criteria and the price per Trust Flow point are covered in our guide to buying backlinks.

The skyscraper technique: outperform content that already attracts links

The skyscraper technique means producing a genuinely better version of content that has already earned links, then contacting the sites that cite the original. Its effectiveness rests on proof of improvement:

• Find the target: content on your topic that has accumulated referring domains but has fallen behind.
• Check you can do better: intent better served, missing sections, current data, concrete use cases.
• Produce the better version: clear structure, verifiable sources, elements that are easy to cite.
• List the sites linking to the original: indexed pages, close topic, link placed within the content.
• Reach out with proof: what they cite today, what is missing, what you add, a simple ask.

For articles over 2,000 words, the gap is clear. They earn +77.2% more backlinks than shorter content (Webnyxt, 2026). What matters is not length but being the reference resource; our guide to SEO copywriting explains how to build it.

Link baiting, for its part, creates an asset designed from the outset to attract links: formats, brief and distribution are covered in our guide to link baiting.

Finding sites: prospecting through the competitor gap

The challenge is not finding websites, but identifying those that already cite your market. A site that links to a comparable competitor is usually open to an editorial approach.

Measure the referring domain gap with your competitors

List 5 to 10 SEO competitors, those holding your target positions, then:

• record their dofollow referring domains and the linking pages;
• isolate the domains that link to several competitors but not to you;
• note the formats that earn these links: case studies, comparisons, resource pages, interviews;
• keep only one site per domain in your shortlist.

Also read their Trust Flow / Citation Flow ratio: below 0.55, it is volume without trust (directories, link farms, networks) and not worth matching; from 0.80 upwards, their volume becomes a real target. These metrics are defined in our guide to backlinks.

Apply the Trust Flow gap rule

Target publishers whose Trust Flow is higher than yours: a gap of +5 to +15 points is very good, a larger gap even better, and a publisher below your Trust Flow adds little. Topic is the next filter: check alignment at site level (Topical Trust Flow), then at the level of the publishing page.

Score a candidate site on five criteria

For each criterion, the table shows what to look for and what should stop you.

Add an editorial check: indexed linking page, link within the body copy, a reasonable number of outbound links. Prioritise strong relevance, low risk and a high likelihood of response, even if authority is not at its maximum.

Outreach: personalise, propose, follow up

Effective outreach reduces randomness rather than sending more emails. Address a specific person (editor, section head) rather than a generic address.

Write a short message focused on the publisher

The message has four elements, in this order:

• Context: the page and paragraph where the link would sit.
• Value for their readers: what your resource adds (update, data, example, tool).
• Evidence: sources, methodology, excerpt or table.
• Ask: a simple action, with the exact target URL and a suggested natural anchor.

Ask for a link to the page you want to strengthen, not to the homepage. Do not impose an exact-match anchor: the split between the four anchor types is decided at campaign level.

Adapt the angle to the method and follow up without pushing

The angle of the message changes with the method, and so does the ask:

One to two factual follow-ups are enough, changing the angle rather than repeating the same message; then stop to protect your reputation.

What no longer works: methods to avoid

Google's spam policies target link schemes: undisclosed purchases, large-scale exchanges, site networks (PBNs), automated links. Penguin has been part of the core algorithm and has run in real time since 2016. The table summarises each practice and what to do instead.

If your profile already contains links of this kind, start with an inventory. Search Console's disavow tool is reserved for manual actions or for schemes you created yourself.

Measure what you have earned

An earned link is checked at publication, then over time: without monitoring, you do not know what still exists.

Check the link at publication

After publication, check each link on these points:

• the link points to the correct URL, without unnecessary redirects;
• the attribute: dofollow, nofollow, sponsored or ugc;
• placement within the content, outside boilerplate areas repeated across the site;
• the anchor, natural and consistent with the target page;
• indexation of the linking page.

Track results over time

Search Console shows external links, anchor text and referring sites. Then track, page by page:

• the dofollow referring domains gained per strengthened URL;
• whether links remain over time: live, lost, unverified;
• the keyword rankings of the strengthened page;
• citations gained or lost in ChatGPT, question by question, if you also target generative engines.

Compare each page with itself, before its first link and today, and speak of correlation, never causation: a gain may come from improved content or seasonality. The inventory and how to read a link profile are covered in our guide to backlink analysis.

Depending on your situation

What comes next depends on your situation:

• You are launching a campaign: the journey, brief, anchor profile and schedule are described in our guide to netlinking campaigns.
• You are targeting AI answers: what generative engines take from links and mentions is covered in our guide to links, mentions and AI citations.
• You have inherited questionable links: a link building audit establishes the full state of the profile before any action.
• You prefer to delegate prospecting: our guide to netlinking service providers lists what a contract should include.

To move from prospects to qualified publishers, the Incremys Offsite media module provides, at the time of writing, a catalogue of publishers with their Trust Flow, topics, traffic over 24 months, GEO performance and price per Trust Flow point. It also flags, URL by URL, the pages to strengthen and their gap with the competitor median.

Frequently Asked Questions About Getting Backlinks

How do you get free backlinks?

Free backlinks are earned in exchange for time: citable content, brand mentions to convert, broken links, resource pages and guest posts. The cost shifts to production and prospecting. These links are more editorial, but slower and less predictable than a disclosed purchase.

Do automatic backlinks work?

No, automatic backlinks do not work. Links created by software land on worthless pages, with repeated anchors and footprints that are easy to spot. Google's spam policies target automated links, and Penguin processes them in real time. Automate the search for and qualification of sites, never the creation of links.

What is a PBN and why should you avoid it?

A PBN is a network of sites, often built on expired domains, created to link to a target site. Google classes it among the link schemes it penalises, and shared footprints (hosting, CMS, templates) give it away. The risk to your domain far outweighs the benefit.

Is guest posting still effective?

Yes, guest posting remains effective when the article delivers genuine value to the host site's readers. Choose publishers whose editorial line overlaps with your expertise, cover a tightly focused topic and place a single link to a page that goes deeper. Done at scale on sites without readers, it becomes a link scheme.

How do you find sites to get backlinks from?

Start from your SEO competitors: record their dofollow referring domains and isolate those that link to several competitors but not to you. Then filter by topic, by Trust Flow gap and by traffic over 24 months. Finally, score each candidate on five criteria before contacting them.

What is the skyscraper technique?

The skyscraper technique means finding content that already attracts links, publishing a genuinely better version, then contacting the sites that cite the original. The message shows what the original is missing and what your version adds. Without proof of improvement, the request is unlikely to succeed.

Should you convert unlinked mentions?

Yes, converting unlinked mentions offers the best ratio of effort to result: the site already cites you, only the URL is missing. The mention carries the signal for generative engines, the link carries the SEO signal, and the two add up. Ask for the link with a clear justification and the exact URL.

What Trust Flow gap should you target between the linking site and your site?

Target a linking site whose Trust Flow is higher than yours: a gap of +5 to +15 points is very good, a larger gap even better. A publisher below your Trust Flow adds little. A shared topic remains a prior filter, because a strong off-topic site reinforces your topical authority less than an aligned one.
