Link building is the work of earning links from other websites to yours. Digital PR is the most reliable modern way to do it: creating genuinely useful research, tools, expert commentary or stories that journalists, partners and industry sites want to reference. Good links come from relevance and trust, not volume, and paid or manipulative links break Google’s spam policies.
Links from other sites remain one of the ways search engines discover pages and judge which sources others rely on. But the tactics that once worked, such as directory submissions, article spinning, private blog networks and bought guest posts, now carry real risk. This guide explains what kinds of links matter, what Google treats as link spam, and a practical, honest approach to earning links and mentions for a B2B or service business. It is written for marketers and founders who want visibility that lasts.
Key takeaways
- Relevance beats authority scores. A link from a respected site in your industry is usually worth more than a link from a high-score site with no connection to your work.
- Buying links that pass ranking credit is link spam. Google’s spam policies say so explicitly. Paid placements must use
rel="sponsored"ornofollow. - Make something worth citing. Original data, useful tools and expert commentary attract links without asking for them.
- Mentions matter too. Unlinked brand mentions in respected publications build recognition with people and AI assistants.
- Start with relationships you already have. Partners, suppliers, clients, associations and events are the easiest honest links to earn.
Why do links still matter?
Search engines use links in two main ways: to discover new pages and to understand which pages other people trust and reference. Google’s link best practices describe links as a signal used to determine relevance and to find new pages. A link from a respected industry publication to your research is, in effect, that publication vouching for you.
Links are not the only signal, and their influence varies by query and competition. A page with excellent content, clear structure and strong technical foundations can rank well with few links in a quiet niche. In a competitive market, the absence of credible external references is often what holds good pages back.
What about AI search?
AI assistants that generate answers draw on content they can access and sources that appear trustworthy. Being cited, linked and mentioned by respected third parties increases the number of places your brand and expertise appear. Our guide to generative engine optimization explains how AI assistants choose sources, and our entity SEO guide covers consistent brand information across the web.
What does Google treat as link spam?
Google’s spam policies for web search define link spam as links intended primarily to manipulate rankings. Examples listed include:
- Buying or selling links for ranking purposes, including exchanging money, goods or services for links or for posts that contain links.
- Excessive link exchanges (“link to me and I’ll link to you”).
- Using automated programs or services to create links.
- Requiring a link as part of terms of service or a contract, without letting the site owner qualify it.
- Text advertisements or advertorials that pass ranking credit.
- Low-quality directory or bookmark site links, and keyword-rich links hidden in widgets or footers distributed across many sites.
- Large-scale guest posting or article marketing campaigns with keyword-rich anchor links.
The same policies cover related shortcuts: site reputation abuse (publishing third-party pages on a trusted site mainly to exploit its ranking signals) and expired domain abuse (buying an expired domain to host low-value content that benefits from its past reputation). Google introduced these specific policies in March 2024.
How should paid and sponsored links be marked?
Google’s guidance on qualifying outbound links sets out three attributes:
| Attribute | Use it for | Example |
|---|---|---|
rel="sponsored" |
Paid placements, advertising, sponsorships and affiliate links | A sponsored article on an industry site |
rel="ugc" |
User-generated content such as comments and forum posts | A link in a blog comment |
rel="nofollow" |
Links you do not want to vouch for, when the other values do not apply | A link to an untrusted source you are discussing |
Paying for exposure is legitimate. Sponsoring an event, advertising in a newsletter or paying for a placement in a trade publication can all bring real visitors. The link simply needs to be qualified so it does not pass ranking credit.
What makes a link valuable?
| Signal | Strong | Weak |
|---|---|---|
| Relevance | An industry publication, association or partner in your field | An unrelated site that accepts any guest post |
| Editorial choice | An editor or writer chose to link because it helps their readers | A link inserted because you paid or asked repeatedly |
| Real audience | The site has readers who might click through | A site built to sell links with no genuine traffic |
| Context | Linked within a relevant paragraph | Buried in a footer, sidebar or list of hundreds of links |
| Destination | Points to the specific page that supports the claim | Points to the home page by default |
Third-party “authority” metrics from SEO tools can help sort a list of prospects, but they are estimates built by those tools, not Google scores. Judge every prospect by whether its readers are people you want to reach.
The Bargaon linkable asset ladder
We plan link earning as a ladder. The lower rungs are quick, low-risk and based on relationships you already have. The upper rungs need more investment but can earn links at scale.
Climb from relationships to research
Most small B2B firms should master rungs 1 to 3 before investing heavily in rung 5.
Rung 1: Existing relationships
Technology partners often list certified agencies. Suppliers and clients may feature case studies. Industry associations list members. Events list speakers and sponsors. Make a list of every organisation you already work with and check whether they have a page where a mention of you would be natural and useful to their visitors.
Rung 2: Genuine profiles and listings
Choose a handful of listings that real buyers use: partner directories, chamber of commerce listings, reputable review platforms and professional bodies. Avoid bulk directory submissions. Keep your name, description and details consistent across every listing.
Rung 3: Expert commentary
Journalists and writers need sources. Responding to relevant press requests, offering a clear and quotable view on industry news and being available at short notice can earn mentions and links in publications your buyers read. Be specific, honest and quick. A useful quote with a real example is worth more than a generic opinion.
Rung 4: Tools and templates
Free calculators, checkers, templates and checklists attract links because they solve a problem quickly. A UTM builder, a meta description checker or a project brief template can be referenced by courses, forums and blogs for years. Keep them maintained and free of unnecessary sign-up walls.
Rung 5: Original research
Surveys, analysis of public datasets and benchmarks from your own anonymised data give journalists something new to report. Research works best when it answers a question your industry argues about, is honest about its sample and method, and is presented with clear charts others can reference. Our own growth systems research is an example of this approach.
How do you run a digital PR campaign?
- Pick a question that matters to your buyers and to the publications they read.
- Find or create the data to answer it honestly. Note the method and sample size.
- Publish the full findings on your site, with charts, a method section and a clear summary.
- Write a short pitch: the headline finding, why it matters now and a link to the full page.
- Send it to a focused list of writers who cover the topic. Personalise every pitch.
- Follow up once. Then move on.
- Track coverage, including unlinked mentions. A polite request to add a link to an existing mention is reasonable.
Which tactics produce links that last?

How should you write an outreach pitch?
Writers and editors receive many pitches every day. The ones that get read are short, relevant and useful. Some principles we follow:
- Lead with the finding or the offer, not with your company. A specific, sourced finding from your own data is far more interesting than “We are a growth agency”.
- Show why it matters to their readers, ideally by referring to something they have written recently.
- Keep it under 150 words, with one link to the full source.
- Offer something concrete: a quote, a chart they can use with credit, or access to the underlying data.
- Never ask for a specific anchor text or a followed link. Let the editor decide how to reference you.
- Do not send attachments on the first message.
Personalisation matters more than polish. One sentence showing you have read the writer’s recent work does more than a beautifully designed press release sent to a generic list.
Worked example: a 90-day plan for a small B2B firm
Imagine a fictional ten-person consultancy with a modest backlink profile. A realistic, honest 90-day plan might look like this:
| Weeks | Focus | Actions |
|---|---|---|
| 1–2 | Relationships | List partners, platforms, associations and clients; request accurate listings or case study mentions where relevant |
| 3–4 | Profiles | Claim and complete five to eight genuine profiles; align name, description and links |
| 5–8 | Commentary | Respond to relevant journalist requests twice a week; publish two opinion pieces on industry news |
| 9–10 | Tool | Launch one free tool that solves a common problem for your buyers |
| 11–12 | Promotion | Share the tool with communities, newsletters and course creators who would find it useful |
| 13 | Review | Measure referring domains, referral traffic and mentions; plan the next quarter, possibly a research project |
This plan will not produce hundreds of links. It may produce ten to thirty relevant ones and several useful mentions, which for most small B2B firms is a meaningful step. The figures are a planning guide, not a promise.
Which pages should earn links?
Not every page is a natural link target. Journalists and writers link to pages that support a claim: research, data, tools, clear definitions and detailed guides. Service pages rarely earn editorial links on their own. That is why internal linking matters. When a guide or research page earns links, its internal links pass visitors and context on to the related service pages. Read our site architecture and internal linking guide to set this up, and our topical authority guide to plan the content clusters that link targets belong to.
Make sure those linkable pages are kept current. A research page with a 2022 dataset or a broken tool loses links over time as writers replace references with fresher sources.
How do you measure link building?
- Referring domains from relevant sites, tracked in Search Console’s Links report or a backlink tool.
- Referral traffic from those links in analytics. Real visitors are the best evidence of a real link.
- Brand mentions in industry publications, linked or not.
- Rankings and impressions for the pages and clusters that received links, in Search Console.
- Enquiries where the source traces back to coverage, tracked in your CRM.
Avoid reporting a raw count of links. Ten relevant, editorially placed links are a better result than two hundred directory entries.
What should you avoid entirely?
- Packages that promise a set number of links per month for a fixed fee.
- Private blog networks and sites that exist only to sell links.
- Guest posts on unrelated sites with keyword-rich anchor links.
- Buying expired domains to redirect or host content.
- Paying to place your content on a trusted site’s subfolder to borrow its reputation.
- Automated outreach that sends the same template to thousands of sites.
If you inherit a backlink profile built with these tactics, focus on earning good links going forward. Google says its systems generally ignore spammy links, and the disavow tool is intended mainly for sites that have taken part in link schemes and received a manual action.
Are links from social media useful?
Links on social platforms are generally nofollowed and do not pass ranking credit directly. They can still bring visitors and help writers discover your work, which can lead to editorial links.
What link building cannot do
Links help good pages get the recognition they deserve. They cannot make a thin page useful, and they cannot overcome serious technical problems. Results are also slow and uneven: a research project may earn ten great links or none, depending on timing and news cycles. Plan for steady, honest effort over many months. Before investing heavily in outreach, check that the basics are in place with our SEO audit checklist and that your priorities are clear in your SEO strategy.
Frequently asked questions
Is it ever okay to pay for a link?
You can pay for advertising, sponsorship or placement, but the link must be qualified with rel="sponsored" or nofollow so it does not pass ranking credit. Paying for links that pass ranking credit is link spam under Google’s policies.
Are guest posts still useful?
Occasional guest articles on respected, relevant sites, written to help their readers, can build reputation and referral traffic. Large-scale guest posting with keyword-rich anchors is listed by Google as link spam.
Do nofollow links have any value?
They can bring visitors, brand recognition and mentions that lead to other links. Google treats nofollow, sponsored and ugc as hints, but you should not expect them to pass ranking credit.
How many links does a page need to rank?
There is no fixed number. It depends on the competition for the query, the quality of your content and the relevance of the links. In some niches, a few relevant links are enough; in others, far more are needed.
Should I disavow bad links?
Usually not. Google says it generally ignores spammy links. Disavowing is mainly for sites with a manual action for unnatural links or a known history of link schemes.
How long does link building take to show results?
Usually months. New links need to be discovered and processed, and their effect depends on how competitive your market is. Treat link earning as a steady, ongoing activity rather than a one-off campaign, and judge it over two or three quarters.
