Backlinks — links from other websites pointing to yours — remain one of Google's most important ranking factors. A site with strong backlinks from trusted sources will almost always outrank a site with better content but no links. Here is how to build them properly.
🌐 Check Backlinks All Performance Tools →A backlink is a link from another website pointing to yours. Google treats backlinks as votes of confidence — when a respected site links to you, it is effectively endorsing your content. The more high-quality sites that link to you, the more Google trusts your site and the higher it will rank.
Run the Backlink Tools on your domain to see your top 100 dofollow backlinks, ranked by the authority of the linking site. Look for three things: your strongest backlinks that are passing the most authority, pages on your site that attract the most links, and any low quality or spammy links that may be hurting you.
Google Business Profile, Yell, Trustpilot, Yelp and industry-specific directories are easy first backlinks that also help local SEO. These are low effort and provide genuine value.
The most reliable way to earn backlinks naturally is to publish genuinely useful content — original data, comprehensive guides, free tools, or strong opinions on industry topics. Content that is better than anything else on the topic attracts links over time.
Write articles for other sites in your industry in exchange for an author bio with a link back to your site. Focus on sites with real audiences and genuine editorial standards — not link farms.
Search for your brand name online. If sites mention you without linking to you, contact them and ask them to add a link. Most will do so willingly.
The underlying mechanism has not changed since PageRank was first described. A page has some quantity of authority; when it links out, it passes a share of that authority to the pages it links to, and that share is split across the links on the page. This has two consequences that most link-building advice never states.
First, a link from a page with 4 outbound links is worth more than a link from a page with 400, all else equal. This is why a link buried in a 500-entry directory listing, or in a sidebar that appears on every page of a site, is worth a fraction of a link placed in the body of a focused article. The authority is being divided.
Second, authority decays as it travels. A link from a page that is itself three clicks from anything anyone links to carries very little, no matter how impressive the domain name attached to it. This is the flaw in judging links by domain-level metrics alone: a link from an obscure, orphaned page on a household-name news site can be worth less than a link from the well-linked hub page of a small, focused industry site.
Not every link is intended to pass authority, and since 2019 the HTML has been able to say which is which. Understanding these four states stops you from chasing links that were never going to count, and stops you from accidentally leaking authority from your own site.
| Attribute | Means | Use it when |
|---|---|---|
| (none) | A normal, endorsing link. Passes authority. | An editorial link you genuinely stand behind |
| rel="nofollow" | "Do not associate my site with this." | Untrusted destinations, links you cannot vouch for |
| rel="sponsored" | Paid or compensated placement. | Advertising, affiliate links, paid placements |
| rel="ugc" | User-generated: comments, forum posts. | Anything a visitor, not you, put on your page |
Google introduced sponsored and ugc in September 2019, and from 1 March 2020 changed how it treats all three: they became hints rather than absolute directives. Google may now choose to consider a nofollowed link for ranking purposes if its systems judge it worth considering. In practice this means two things.
sponsored. Failing to disclose compensated links is what Google's spam policies actually target, and the disclosure is what keeps you the right side of them.ugc at minimum. A site that acts as an open link farm for spammers is a site Google has reason to distrust.Anchor text — the clickable words of a link — tells Google what the destination page is about. That makes it valuable, and that is exactly why it is the thing manipulators over-optimise, and therefore the thing that gives them away.
Look at the anchor text of any site that has never bought a link. It is dominated by four things: the brand name, the bare URL, the page title, and generic phrases — "click here", "this guide", "read more", "their site". Exact-match commercial anchors ("cheap car insurance quotes") appear rarely and by accident, because that is simply not how human beings write links into their own prose.
Now look at a profile built by buying links. It is stuffed with exact-match commercial anchors, because that is what the buyer was paying for. No pattern is easier to detect at scale, and none is more obviously unnatural.
The same logic applies to the pages the links point to. A natural profile links overwhelmingly to the homepage and to genuinely useful content. A profile where every link lands on a commercial money page, with a commercial anchor, describes no real-world publishing behaviour.
The folklore around link penalties is a decade out of date, and it leads people to make bad decisions in both directions — panicking about links that do nothing, and disavowing links that were fine.
Before 2016, the Penguin algorithm ran periodically and demoted whole sites caught with manipulative link profiles — and you stayed demoted until the next refresh, which could be a year away. Penguin 4.0, released in September 2016, changed both halves of that. It runs in real time as part of the core algorithm, and it is granular: it discounts the offending links rather than demoting the entire site.
Google's link spam update of December 2022 used its SpamBrain machine-learning system to detect both sites buying links and sites selling them, and to neutralise the links — meaning the credit they were passing is simply removed.
Understand what this implies. The most likely outcome of a bought link campaign in 2026 is not a dramatic penalty. It is that you pay for links that pass nothing at all. The money leaves; the rankings never arrive; there is no error message. That is a worse business outcome than a penalty in one specific way: a penalty at least tells you to stop.
Algorithmic neutralisation is the common case, but a human reviewer can still issue a manual action. It appears in Google Search Console under Security & Manual Actions → Manual actions, typically as "Unnatural links to your site". If you have never looked at that report, look at it now — it takes ten seconds, and it is the only place Google tells you directly.
Every few months someone runs a backlink audit, sees a hundred links from sites they have never heard of, and reaches for the disavow file. This is nearly always a mistake, and it is a mistake that can actively harm the site.
Google's own position has been consistent for years: the overwhelming majority of sites should never use the disavow tool. Its systems already ignore the spam links that accumulate around any site that exists on the open web — the scraper sites, the auto-generated directories, the stolen-content mirrors. They arrive on their own, they arrive at every site, and they are already being disregarded.
The disavow file, meanwhile, is a blunt instrument that you point at your own site. Disavow a domain and you throw away every link from it, permanently, including the good ones you did not notice. The tool exists for two narrow situations:
Note that both conditions describe links you caused. "I do not recognise this domain" is not a reason to disavow anything.
Before earning a single new link, most sites can recover authority they are already losing. This is the cheapest work in the whole discipline and it is almost universally skipped in favour of the more exciting business of acquiring new links.
A page that once earned links and now returns 404 is a page whose links are pointing at nothing. Every one of those inbound links is dead weight. Find them, and 301-redirect the dead URL to the closest genuine equivalent on your site. The authority resumes flowing.
This is the standard error and it defeats the purpose entirely. Google treats a redirect to an irrelevant destination as a soft 404 — the redirect is honoured for users, but the page is treated as missing, and no authority is passed. A redirect only preserves link value when the destination is genuinely a replacement for what the user was looking for. If there is no equivalent page, a clean 404 is the honest answer and a redirect to the homepage buys nothing.
Google has stated that 301 and 302 redirects do not lose PageRank. But long chains — a URL redirecting to a URL redirecting to a URL — are still a problem: crawlers give up after a handful of hops, and every extra hop is latency for the human. Where you find a chain, point the first URL directly at the final destination.
Somebody wrote about you and did not link. It happens constantly — in news coverage, in forum threads, in "tools I use" round-ups. These are the easiest links available to any site, because the editorial decision to endorse you has already been made. The only thing missing is the anchor tag, and a polite email usually fixes it.
"How many links do I need?" is unanswerable in the abstract and trivially answerable in context: as many as the pages currently occupying the positions you want. The work is in reading their profiles correctly rather than counting them.
Journalists, bloggers and industry writers link for reasons, and there are not many of them. Almost every link that has ever been earned falls into one of these categories.
A statistic is the most linkable object on the internet, because every writer covering a topic needs one and almost nobody produces one. You do not need a large survey. Any business sitting on its own operational data has a study in it — pricing across a sector, response times, failure rates, seasonal demand. Publish the numbers and the method, and writers will cite you, because you have become the only available source.
Tools earn links passively and permanently, because they get recommended in answers to questions people keep asking. The bar is lower than it looks: a genuinely useful single-purpose calculator will out-earn a mediocre thousand-word article by an enormous margin, and it keeps earning for years.
Not the fifteenth generic overview of a broad topic — those are unlinkable because fourteen better ones already exist. The comprehensive treatment of one specific, unglamorous, difficult question that everybody in your industry has to solve and nobody has properly documented.
Reporters on deadline need a quotable expert, fast. Responding quickly, with a usable quote and no marketing padding, gets you cited — often in publications you could not reach any other way. The differentiator is almost always speed and usability, not credentials.
Guest posting is not banned, and people who say it is have misread the guidance. What Google's link spam policies target is large-scale article campaigns with keyword-rich links — the industrialised version, where the article exists solely as a vehicle for the anchor text.
The distinction is one of intent, and it is legible in the artefact itself:
Google's stated position on the paid or promotional version is unambiguous: if the primary purpose of the article is to obtain a link, the link should be marked nofollow or sponsored. Which is another way of saying: if the link is the point, it is not going to count — so the only guest posting worth doing is the kind where the article is the point.
A valuable backlink comes from a website that is relevant to your industry, has its own strong backlink profile, and links to you naturally within its content — not in a footer, sidebar or paid link directory. The link should be dofollow (not marked nofollow) and the anchor text should be descriptive rather than generic.
There is no fixed number. It depends on your competition. Search for your target keyword and look at the backlink profiles of the pages ranking in positions 1-3. You need a comparable number of links from comparable quality sites. For local businesses, 20-50 quality backlinks may be enough. For competitive national keywords, hundreds may be needed.
Avoid paid links, link exchanges, links from irrelevant sites, links from private blog networks (PBNs), and links acquired through automated tools. Google's Spam Brain detects these patterns and can penalise your site with a manual action or algorithmic demotion. Build links slowly and naturally from genuinely relevant sources.
No. Since 1 March 2020 Google treats nofollow, sponsored and ugc as hints rather than absolute directives, meaning it may still consider such a link. Beyond ranking, a nofollow link from a site with a real audience delivers referral traffic and brand searches, both of which have value regardless of how the link is marked.
Almost certainly not. Google's guidance is that the great majority of sites never need it — its systems already ignore the scraper and auto-directory links that accumulate around every site. The tool is intended for cases where you have a manual action for unnatural links, or where you know manipulative links were built for your site and cannot be removed at source. Disavowing a domain discards every link from it permanently, including good ones.
A manual action is possible, but the more common outcome since the December 2022 link spam update is that SpamBrain simply neutralises the links — the credit they would have passed is removed. The site is not visibly punished; the purchased links just do nothing, and the money is wasted with no notification that anything is wrong.
Google has stated that 301 and 302 redirects do not lose PageRank, so redirecting a removed URL to a genuine replacement preserves the value of links pointing at the old address. However, redirecting an unrelated page — for example, sending every deleted URL to the homepage — is treated as a soft 404, and passes no value at all.
