Every link on this page can be earned without paying for it. That does not make it free. Each one costs time, and the reason most people give up on free link building is that nobody told them how much time before they started.
So this guide gives you both numbers. What the tactic is, and roughly what it takes to land one link with it. Fourteen sources, ranked loosely by how quickly a site with no authority can get results, plus a section on the free tactics that have stopped working and will now waste your month.
How this guide was put together
I read the pages currently ranking for this term. They are decent lists and they share the same three gaps: none of them tells you how long a tactic takes, none separates the dofollow links from the nofollow ones, and none admits that several of the tactics they recommend stopped working years ago. Every platform named below was loaded in a browser in August 2026 to confirm it still exists and still accepts submissions. Where a site blocked automated access, I have said so rather than pretend I checked.
The honest summary, before the list
| Tactic | Time per link | Link type | Hit rate | Needs existing content |
|---|---|---|---|---|
| Product and startup directories | 15 to 30 min | Mostly dofollow | Very high | No |
| Unlinked brand mentions | 20 min | Dofollow | Medium | No |
| Journalist request platforms | 30 to 60 min | Dofollow | Low per pitch | No |
| Testimonials for tools you use | 30 min | Dofollow | High | No |
| Podcast guesting | 2 to 4 hours | Dofollow | Medium | No |
| Broken link building | 1 to 2 hours | Dofollow | Low | Yes |
| Guest posts | 4 to 8 hours | Dofollow | Medium | No |
| Original data or research | 15 to 40 hours | Dofollow | High per asset | Yes |
| Free tools and calculators | 20 to 60 hours | Dofollow | High per asset | Yes |
| Expert roundups | 20 min | Dofollow | Medium | No |
| Community profiles | 10 min | Mostly nofollow | Very high | No |
| Supplier and partner pages | 20 min | Dofollow | High | No |
| Local citations | 15 min | Mixed | Very high | No |
| Republishing on owned platforms | 30 min | Nofollow | Very high | Yes |
Two patterns are worth reading off that table. The tactics with the highest hit rate are the ones nobody wants to do because they feel small, and the tactics that build real authority take days, not minutes. Both are true at once, and a sensible first month does the small ones while one big one is being built. If you want the underlying mechanics before picking a tactic, our primer on what backlinks are covers them.
1. Product and startup directories
The fastest links available to a new site, and the ones most guides bury at the bottom. Directories that list software, startups and tools give you a page with your name, your description and a link, usually within a week of submitting.
AlternativeTo is the strongest of them for anything software shaped. You add your product as an alternative to something established, users vote, and the listing carries a link. Crunchbase is worth the twenty minutes for any registered company, and its profiles rank for your brand name, which matters more than the link.
For newer products, the launch platforms are the fastest route. Uneed states plainly on its homepage that listed products get a link from a DR 75 domain, and Microlaunch runs a similar model with a daily leaderboard where the top launches of each month stay on the front page.
Product Hunt and SaaSHub both belong on this list too. I could not screenshot either of them because both block automated browsers, so take those two as named from experience rather than verified this morning like the rest.
The catch worth knowing: directory links are easy for everyone, which means they are worth less than the effort ratio suggests. They are a floor, not a strategy. Do fifteen of them in a week, then stop and do something harder.
2. Turn unlinked brand mentions into links
Someone has already written your name somewhere without linking it. This is the highest yield twenty minutes in link building because the writer has already decided you are worth mentioning, so the ask is trivial.
Search your brand name in Google with your own domain excluded, set up a Google Alert for it, and check the results monthly. When you find a mention, email the author and ask if they would mind linking the mention to the relevant page. Roughly a third say yes, and they say yes quickly. Seeing which of them actually send people is a separate job, covered in our guide to how to check backlinks in Google Analytics.
This works far better than cold outreach because you are not asking for a favour. You are pointing out an incomplete sentence.
3. Journalist request platforms
Reporters need sources on deadline and publish requests for them. Answer well and you get quoted with a link, often from a domain you could never reach any other way.
Qwoted is the most active of them now, with Featured, SourceBottle and Connectively covering the rest.
The hit rate per pitch is low, maybe one in ten to one in twenty, and it drops further if you send anything that reads like a template. What works: answer within the first hour, give a specific number or a first hand story rather than an opinion, and keep it to four sentences. What does not work: pitching queries that are not genuinely in your field, which is most of them.
If you can only build one habit from this page, make it this one. Twenty minutes a day on these platforms outperforms every other free tactic over a year, and the links land on news sites rather than blogs.
4. Write testimonials for tools you already pay for
Companies love putting customer quotes on their homepage and they nearly always link back to the customer's site. Nobody asks for these, so the acceptance rate is high.
Make a list of every tool your business pays for. Email each one offering a short written testimonial, and include the testimonial in the email so there is nothing for them to chase. Two or three out of ten will publish it.
Keep it specific. "It saved us time" gets ignored, and "it cut our monthly reporting from six hours to forty minutes" gets published.
5. Podcast guesting
Every episode has show notes, and show notes carry a link to the guest. The link is usually dofollow and the audience is real, which is more than most link tactics can claim.
Find shows in your niche with a search engine for podcasts, filter for ones publishing in the last month, and pitch the host with a specific topic rather than a request to come on. Small shows say yes far more often than large ones, and their links count the same.
Budget two to four hours per appearance including prep and recording. That is expensive per link, so treat the link as the side benefit rather than the goal.
6. Broken link building
Find a page that links to something dead, tell the owner, and suggest your page as the replacement. It works because you are doing them a favour first.
The realistic hit rate is low, around one in twenty, and it only works when you already have a page that genuinely replaces what died. Check the resource pages in your niche, run them through a broken link checker, and only pitch where the fit is exact. Pitching a loose match is what makes this tactic feel useless.
7. Guest posts
Still the most reliable dofollow link on the list, and still the most work. Pitch a specific headline to a site whose audience overlaps with yours, write something you would have published yourself, and put the link in the body where it makes sense rather than only in the bio.
Four to eight hours per post is honest. If you want a fuller breakdown of how this fits alongside the other tactics, we ranked all of them by hit rate in our guide on how to get more backlinks.
Two warnings. Sites that advertise guest posts openly usually charge, which puts them outside this page. And a guest post on a site with no traffic is worth nothing regardless of its domain rating.
8. Publish original data
The single most effective free tactic and the slowest. A number nobody else has gets cited, and citations become links without you asking for them.
You do not need a large study. Survey two hundred people in your industry, or analyse data your own product already generates, and publish the result with a clear methodology. One good statistic gets picked up by writers for years, and each pickup is a link from someone who found you rather than someone you emailed.
Budget a working week. Then spend a second week telling people it exists, because unpromoted research earns nothing.
9. Build a free tool
A calculator, a checker, a generator, anything that does one job in a browser without a signup. Tools get linked from resource lists, from forums, and from people answering questions, and the links keep arriving for years.
This is the highest ceiling item on the page and the highest cost. It only makes sense if the tool is something your audience needs repeatedly and if you can build it in a couple of weeks rather than a quarter.
10. Expert roundups
Writers assembling a roundup post need quotes and usually link every contributor. Watch for the requests on social platforms, answer within the day, and give them something quotable rather than safe.
Twenty minutes for a link on a page that other people will also promote is good value. The quality varies wildly, so check whether the site has real traffic before spending the time.
11. Community profiles and answers
Forums, communities and Q&A sites let you fill in a profile with a link. Most are nofollow, which people use as a reason to skip them. That is a mistake, because these links get you discovered by real people and by the AI assistants that now read those communities when answering questions.
The rule that keeps you out of trouble: participate first, link second, and only link when the link genuinely answers the question. Dropping your URL into threads is spam and gets your account removed.
12. Supplier, partner and customer pages
Every company you work with has a partners page, a customers page or a case study section. Almost none of them are complete, because nobody at those companies is chasing them.
Email your suppliers and ask to be listed. Offer to write the case study yourself. This has a high hit rate for the same reason testimonials do: you are removing work rather than adding it.
13. Local citations
If your business has an address, the local directories and your Google Business Profile give you links and, more importantly, consistency in how your name and address appear across the web. Set them up once, keep the details identical everywhere, and revisit twice a year.
The links themselves are mixed quality. The visibility in local search is the real payoff.
14. Republish on platforms you already own
Medium, Substack, LinkedIn articles and your own newsletter archive all let you republish with a link home. The links are nofollow, so treat them as distribution rather than authority.
Worth doing because the republished version often ranks for terms your own site cannot reach yet, and because AI assistants pull from these platforms heavily when they cite sources.
The free tactics that no longer work
This is the section the ranking pages leave out, and skipping it is what makes free link building feel fruitless.
Backlink generators. Any tool promising hundreds of links at the press of a button is producing links from sites Google already ignores, and at worst from a footprint that gets your domain associated with a spam network. There is no version of this that works.
Comment spam. Blog comment links have been nofollow by default across every major platform for over a decade. Leaving your URL under an article does nothing for rankings and takes you off the reading list of the person who moderates it.
Web 2.0 mini sites. Creating a dozen free blogs to link back to yourself was a real tactic in 2012. It is now a pattern that is trivially detected and it is the fastest way to make your link profile look manufactured.
Mass directory submissions. Fifteen relevant directories help. Five hundred generic ones is a footprint, not a strategy, and the sites selling those packages know it.
Article spinning. Publishing rewritten versions of the same article across free sites earns nothing and dilutes whatever the original had.
The pattern is consistent. Free tactics work when a human on the other end decided to publish your link. They fail when the link was placed automatically.
Checking that the links you earned actually count
Earning a link and having it count are separate events. Three checks, all free.
Is it indexed. A link on a page Google has never crawled does nothing. Search the exact URL in Google. If it does not appear, the page is not indexed and neither is your link.
Is it dofollow. Open the page source and look at the link tag for a nofollow or sponsored attribute. Both still carry value for discovery and for AI citation, but neither passes authority in the way people assume. We explain the difference and when each one matters in our guide to dofollow backlinks.
Is it still there. Links get removed during redesigns and content refreshes. Check your best ones twice a year, because a link you earned and lost is worth reclaiming with one email.
When free stops scaling
Free link building has a ceiling that arrives sooner than most people expect. You run out of unlinked mentions, you exhaust the directories in your category, and the remaining tactics all cost a working day or more per link.
At that point the honest options are to pay for placements, to hire someone to run outreach, or to trade. Distribb runs a backlink exchange where sites in the network link to each other, so no money changes hands per link. It is not free: the exchange is part of a paid plan, which is exactly why it is not one of the fourteen tactics above.
The limitation worth stating before you consider it: you do not choose which specific site links to you. Matching is done by topic and authority, so if you need a link from one named publication, an exchange is the wrong instrument and outreach is the right one. We compared the main options in our roundup of the best backlink exchange platforms.
Frequently asked questions
Are free backlinks safe? The ones earned from a human decision are safe, and the ones generated automatically are not. Every tactic in the numbered list above involves a person choosing to publish your link, which is the line that matters.
How many free backlinks do I need? Nobody can give you a number, because it depends entirely on what your competitors have. Look at the pages ranking for your target term, count their referring domains, and use that as the target rather than any figure from a blog post.
How long before free backlinks affect rankings? Weeks to months. Google has to crawl the linking page, and the effect on a competitive term is cumulative rather than immediate. Sites that start from zero usually see movement on long tail terms first, which is why we recommend starting there in our guide to getting the best backlinks.
Do nofollow links help? Yes, in ways that do not show up in a link tool. They bring visitors, they get you cited by AI assistants, and they often lead to a dofollow link later when someone finds you through them.
What should I do first with no budget and no authority? Fifteen directories in week one, then a daily habit on journalist request platforms, then one piece of original data. That sequence gets links arriving while the slow asset is being built.
Where to start this week
Pick the three tactics at the top of the table, do them properly, and ignore everything else until they are done. Fifteen directory listings, every unlinked mention converted, and a daily twenty minutes answering journalist requests will produce more links in a month than reading another list will.
When the free routes stop producing, our page on how to get backlinks to your website covers the paid and hybrid options, and you can see how link trading works on the Distribb backlink exchange.
