Free Backlinks: 8 Ways to Earn Them Within Google's Rules

Free backlinks come from unlinked mentions, broken links, real partners and press quotes: 8 methods that cost time, not money, and avoid link spam.

In short: a free backlink is a link another site gives you because your page is useful to its readers, which is exactly the kind of link Google rewards. The methods that work (reclaiming unlinked mentions, fixing broken links, real partners, press quotes) cost time rather than money, while anything that produces links in bulk falls under Google’s definition of link spam.

Free does not mean effortless. An editorial link requires something worth citing and a reason for the right person to notice it. The eight methods below run from fastest to most demanding.

For a small business starting from zero, a sensible order is: methods 1 to 3 in the first week, because they use what already exists, then one citable resource (method 6) per quarter. Everything else is a bonus when you have time.

A backlink is a link from another website to yours. Google uses links to discover pages and as a trust signal, but not blindly. Its spam policies list the practices designed to manipulate that signal, including:

  • buying or selling links that pass ranking credit;
  • excessive link exchanges (“link to me and I’ll link to you”) and partner pages built only to cross-link;
  • guest posts, advertorials or press releases with keyword-rich anchor links;
  • links from low-quality directory or bookmark sites;
  • keyword-rich links in forum signatures or comments.

The test that sums it up: a link is healthy when it would exist even if Google did not. A supplier linking to you because you are its authorized dealer, yes. A directory that accepts any site without looking at it, no.

Links can also carry attributes. According to Google, rel="sponsored" marks paid or advertising links, rel="ugc" marks user-generated content such as comments and forum posts, and rel="nofollow" covers the other cases where a site does not want to vouch for a link. Google treats these as hints and generally does not use them for ranking. They keep their value as a source of traffic.

The quickest wins come from links that are already half-earned. You are not asking for a favor, you are fixing an omission.

1. Reclaim unlinked mentions

This is the highest-return method: someone already wrote about you, and only the link is missing.

  1. Set up Google Alerts for your business name, product names and the names of your founders.
  2. For each mention, check whether it links to your site.
  3. If it does not, email the author. Keep it short: thank them, then give the exact URL of the page most useful to their readers.

Response rates tend to be good because the request is legitimate: you are helping the writer complete their article.

After a redesign, other sites often keep linking to old URLs that now return a 404 error. Those links are wasted. Ahrefs Webmaster Tools (now branded as the free Ahrefs plan) is free for sites you verify and shows up to 1,000 backlinks at once, including those that land on broken pages. Redirect each old URL to the closest current page with a 301 redirect, and you recover the link without asking anyone for anything.

The same logic works on other people’s sites. If a well-known article in your industry links to a resource that has disappeared and you have an up-to-date equivalent, tell the author. This is classic broken link building, and it works best when your page is a genuine replacement, not a loose match.

3. Use the relationships you already have

Every business has natural links it never claims: suppliers, distributors, clients, trade associations, your local chamber of commerce, the youth team or charity you sponsor, the college that sends you interns. Many of them have a “partners,” “where to buy,” “members” or “case studies” page.

Make the list and simply ask to be included. The limit is the one Google sets: no systematic link swaps with unrelated sites.

Searching “free backlink sites” turns up lists of hundreds of directories, bookmarking sites and profile pages. Most of them are exactly what Google’s spam policies call low-quality directories, and links from them are ignored at best.

4. Pick a few directories, not a hundred

A few directories are worth your time because real customers use them:

  • your professional body or trade association’s member directory;
  • recognized industry platforms in your niche;
  • local business listings run by your city, county or chamber of commerce.

They also support local visibility, provided your name, address and phone number are identical everywhere. The filter question is simple: could a real customer find you through this directory? If not, skip it.

5. Become a source for reporters

Reporters constantly need experts, numbers and quotes. Three ways to get in their path:

  • Source request services. HARO (Help a Reporter Out), the original free digest, was shut down by Cision in its rebranded Connectively form, then sold to Featured.com in April 2025, which relaunched it. Source of Sources, started by HARO’s founder, is another free digest. Competition on each query is intense, so answer fast, briefly, and only where you are a real expert.
  • Requests posted on social media. Journalists post call-outs on X, LinkedIn and Bluesky. In the UK, the #journorequest hashtag is the long-standing convention.
  • Local and trade press. They are more accessible than national outlets. An original number about your industry in your state or county often interests a regional newspaper or a trade publication.

A press article does not always include a link. The visibility is still real, and the mention can then be reclaimed with method 1.

6. Create a resource that deserves to be cited

Sites do not link to “quality content” in general. They link to one specific thing they need for their own article:

  • Original data: a survey of your customers, a price index, an annual benchmark.
  • A tool: a calculator, a simulator, a downloadable template.
  • A reference guide on a technical question in your field, kept up to date.

This is the slowest method and the one that keeps producing links for years. A well-run business blog is the natural home for these resources, and a simple tool such as a break-even calculator shows the kind of page other writers reference when they explain a concept.

7. Write for other sites, for their readers

Guest posting is still legitimate when it serves the host site’s audience. It becomes spam when its purpose is to place an optimized link: Google specifically names guest posts with keyword-rich anchor text. Pitch topics where you bring real expertise, accept a link on your name or brand, and accept that it may be marked nofollow. Readers you convince will find you anyway.

8. Join communities without spamming them

Specialist forums, professional groups, Reddit: links there are usually ugc or nofollow, so they have no direct ranking effect. Their value lies elsewhere, as explained in our article on social media and SEO: people read you, remember you, and some of them run websites that will cite you later. Answer the question first, and add a link only when it genuinely completes the answer.

The Links report in Google Search Console lists the main sites linking to you, your most linked pages and the anchor text used. Add Ahrefs Webmaster Tools to spot lost links and links landing on broken pages. A monthly check is enough for most small businesses. Our roundup of SEO tools covers how to set them up.

If you are weighing whether to do this yourself or hire help, our guide to SEO pricing shows what link building services actually cost, and why the cheapest offers are usually the riskiest.

One last rule of caution: if a method promises dozens of links in a few days, it is manufacturing links rather than earning them. That is one of the SEO mistakes that costs the most to undo.

Frequently asked questions

Can a free backlink hurt my site?

Yes, if it comes from a tactic Google classifies as link spam: low-quality directories, keyword-stuffed forum signatures, excessive link swaps or guest posts packed with exact-match anchors. The price of a link is not the issue. What matters is why the link exists, and whether it would still exist if search engines did not.

Are nofollow backlinks worth anything?

Google's documentation says nofollow, sponsored and ugc links are generally not used to pass ranking credit, though Google treats them as hints. They still send visitors. A nofollow link in an article your customers actually read can bring more leads than a followed link on a site nobody visits.

Does HARO still exist?

Yes. Cision shut the service down under the Connectively name in late 2024, then sold the HARO brand to Featured.com in April 2025, which relaunched the free email digest. Source of Sources, started by HARO founder Peter Shankman, is another free option. Expect heavy competition on every query.

How many backlinks do I need to rank?

There is no universal number. It depends on the pages already ranking for your query. Count the distinct referring domains pointing to the top five results: that is the gap you need to close. For local or niche long-tail queries, that gap is often a handful of relevant links, not hundreds.
