Link Building: How to Earn Links Worth Having

Link building is the work of getting other websites to link to pages on yours. Search engines treat a link as a kind of reference: one site telling its readers that another page is worth their time.

This guide covers what separates a good link from a wasted one, the tactics that hold up, and how to tell whether the effort is paying off.

Key takeaways

• A link is worth having when it comes from a relevant, trusted site and is placed in the main content by an editor who chose to add it.
• The most reliable way to earn links is to publish something other writers need to cite, such as original data, a useful tool or a clear definition.
• Outreach works when it is small, specific and offers the recipient something useful for their own readers.
• Buying links, swapping links at scale and using private blog networks all break Google's spam policies and put your site at risk.
• You should judge link building by referring domains to the pages that matter and by how those pages rank, not by the raw number of links.

What is link building and why does it matter?

Link building is any deliberate effort to increase the number and quality of links pointing to your site from other sites. It matters because links remain one of the signals search engines use to judge which pages deserve to rank.

A link from another site is usually called a backlink. The site it comes from is a referring domain. Ten links from one site count as ten backlinks but only one referring domain, and the second number is usually the more telling one.

Links cannot rescue a weak page. If the content does not match what the searcher wants, links will rarely be enough, which is why search intent comes first.

What makes a link worth having?

A link is worth having when a real editor, on a site your audience would recognise, chose to point their readers at your page. Everything else is a variation on that test.

Use this table to sort a link opportunity quickly.

Two notes on attributes. A link marked rel="nofollow", rel="sponsored" or rel="ugc" tells search engines the site is not vouching for the target in the usual way. These links can still send readers and build awareness, so do not turn them down, but do not plan a campaign around them either.

Ask one question before pursuing any link: would you still want it if search engines did not exist? If the answer is yes, it is almost certainly a good link.

How do you earn links without buying them?

You earn links by giving other writers a reason to cite you, then making sure they know the page exists. The first half is the hard part, and most failed campaigns skip it.

A simple process:

1. Pick the page that should earn links. Product pages rarely attract references. Research, guides, tools and glossaries do.
2. Make it citable. Add something a writer can point to: a figure from your own data, a clear definition, a calculator, a template or an original diagram.
3. List who would cite it. Look for journalists, bloggers and newsletter writers who have covered the subject recently. A short, accurate list beats a long, vague one.
4. Write a short, specific pitch. Say what the page is, why it helps their readers and where it would fit. Three or four sentences is enough.
5. Follow up once. Then stop. Persistent chasing damages your name with the people you most need.
6. Pass the value on. Link from the page that earned links to your commercial pages, so the benefit spreads. This is where internal linking does its work.

For example, a payroll software company could publish a plain guide to payroll deadlines with a downloadable calendar. Accountancy blogs and small business newsletters have a reason to reference it, because it saves their readers time.

Other tactics that hold up:

• Digital PR. Offer journalists data or expert comment on a story they are already covering.
• Unlinked mentions. Find articles that name your brand without linking, and ask politely for the link.
• Broken link replacement. Find a dead link on a relevant page and suggest your page as a working alternative.
• Partners and suppliers. Companies you already work with often have customer, partner or case study pages.

Which link building tactics should you avoid?

Avoid any tactic where the link exists only because you paid for it, traded for it at scale or created it yourself on a site built for that purpose. Google's spam policies describe these as link schemes, and its systems are designed to ignore or penalise them.

The common ones:

• Paid links that pass as editorial, with no sponsored attribute.
• Private blog networks, which are groups of sites built only to link to each other or to clients.
• Large scale link exchanges, where sites agree to link to each other for no reader benefit.
• Automated links from comment spam, forum profiles or scraped directories.
• Keyword stuffed anchors repeated across many guest posts or widgets.

The risk is not only a penalty. More often the links are simply ignored, and you have paid for nothing.

How do you measure whether link building is working?

Measure link building by the growth in relevant referring domains to your target pages, and by whether those pages rank and attract visits. Counting total links tells you very little.

Check these in order:

1. New referring domains. Use the Links report in Google Search Console, or a tool such as Ahrefs or Semrush, and note which new sites link to you each month.
2. Quality of those domains. Open them. Are they relevant sites with real readers?
3. Pages receiving links. Are links reaching the pages you planned, or only the homepage?
4. Rankings and clicks. Watch the target pages, and the pages they link to, in Search Console over several months.
5. Referral visits. Check analytics for traffic arriving from the linking pages.

Third party scores such as Domain Rating or Authority Score are useful for comparing sites, but they are estimates made by tool providers. Google does not use them. Treat them as a rough guide, not a target.

Frequently asked questions

How many backlinks do you need to rank?

There is no fixed number of backlinks needed to rank. It depends on how competitive the search is and how strong the pages already ranking are. Compare the referring domains of the top results for your keyword to get a realistic sense of the gap.

Are nofollow links worth anything?

Nofollow links are worth having when they come from sites your audience reads. They can send visitors and put your brand in front of writers who may link normally later. They should not be the main goal of a link building campaign.

Is it safe to pay for links?

Paying for links that pass ranking credit breaks Google's spam policies. If you pay for a placement, such as an advert or a sponsored article, the link should carry the sponsored attribute. Paid links without it risk being ignored or triggering a manual action.

How long does link building take to show results?

Link building usually takes months to show results, not weeks. A link has to be published, crawled and weighed alongside everything else on the page. Expect gradual movement, and judge the work over a quarter or longer.

Link building rewards patience and a page that deserves the attention. If you want a second opinion on where your links should come from, start a conversation.
