Free Backlinks: Which Free Link Sources Count and Which Google Ignores
On 7 of 10 free link sources we checked, the link you add is nofollow or ugc. The free links that count are the ones someone chooses to give you, and here is how to get them.
Free backlinks are links you get without paying the linking site: profiles, listings, forum posts, comments, and editorial links someone chose to give you. Only the last kind is worth chasing. On most free sources, the link you add yourself is marked nofollow or ugc, which asks Google not to count it, and several of the classic sources sit on Google's own link spam list.
Below: which free sources pass anything, what a typical free backlink list really contains, what Google says, and five ways to get free links that count.
Short answers#
- Do free backlink sites work? Mostly not for rankings. On 7 of the 10 platforms we checked, the link you add yourself was nofollow or ugc. The check.
- What is on a typical free backlink list? Mostly links you place yourself. In the top result's list of 24 sites, 5 need someone else's editorial decision. The breakdown.
- Does Google allow free directory and forum links? Only if they don't try to pass credit. Low-quality directories and forum signatures with optimized links are named as link spam. Google's wording.
- Are nofollow links worthless? No. They can send visitors and help discovery, and Google treats nofollow as a hint, not a rule. They just shouldn't be your plan. When they help.
- How do I get free backlinks that count? Reclaim mentions, ask people who know you, answer journalists, publish one page worth citing, and contribute where communities reward it. Five steps.
Which free backlinks pass ranking credit?#
A link passes credit when the site publishing it doesn't qualify it. Google's qualify outbound links page tells site owners to mark "user-generated content (UGC) links, such as comments and forum posts, with the ugc value," and its SEO Starter Guide says every link posted by users should get "a nofollow or similar annotation automatically added by your CMS."
So we checked whether platforms do that. On 9 October 2026 we fetched a public page on 10 platforms commonly listed as free backlink sources and read the rel attribute on the link a user supplies: the profile website field, the comment author link, the directory listing, the forum signature, the citation.
Seven of the ten qualify every link a user adds. GitHub's profile website field carries rel="nofollow me", Gravatar marked 17 of 17 profile links nofollow, Hotfrog marked all 16 business links nofollow, Warrior Forum marked all 44 post and signature links nofollow, and Wikipedia marked all 132 outside citations nofollow. Comment author links on WordPress and Blogger come out as ugc nofollow.
The three that left links plain are the interesting part: DEV profiles, Hacker News comments and Stack Overflow answers. All three are communities where you only get seen by contributing something people vote on or reply to. That matches Google's own advice to site owners, who "might remove this attribute from links posted by members or users who have consistently made high-quality contributions over time." The free links that pass credit are the ones a community gives back for real work, not the ones a form gives anyone.
Two caveats. Stack Overflow's markup came from its public API, because the page itself blocked our fetch. And 14 popular sources, including Medium, LinkedIn, Quora, Reddit and Yelp, blocked automated requests, so they are not in the chart.
What is on a free backlink list?#
The top organic result for "free backlinks" in our check was First Page Digital's guide, with a table of 24 "Free Backlink Sites and Resources." We sorted each entry by one question: who decides whether the link exists?
- Closed (2 of 24). By the list's own descriptions, DMOZ is "now archived" and Yahoo Directory is "no longer accepting new submissions."
- You publish it yourself (7 of 24). Medium, WordPress.com, Blogger, Quora, SlideShare, Academia.edu and GitHub. You write the page, you place the link. Google's spam policies list "Creating low-value content primarily for the purposes of manipulating linking and ranking signals."
- You submit a listing (10 of 24). AllTop, Best of the Web, Spoke, TripAdvisor and six Singapore business directories. A real listing where your customers look is useful. A submission made for the link is what Google calls a "Low-quality directory."
- Someone else decides (5 of 24). TechCrunch, Edutopia, WebMD, Healthline and Lonely Planet. These are editorial links, and they are only free in the sense that you don't pay. You earn them with a story, an expert article or data.
So 17 of 24 are links you place yourself, and the five that could actually move rankings are the five that need work. The guide calls the archived DMOZ listings a source of "valuable backlinks." It does not mention nofollow anywhere.
What does Google say about free link sources?#
Google defines link spam as "creating links to or from a site primarily for the purpose of manipulating search rankings." Its examples read like the table of contents of a free backlink list:
- "Low-quality directory or bookmark site links"
- "Forum comments with optimized links in the post or signature"
- "Using automated programs or services to create links to your site"
- "Creating low-value content primarily for the purposes of manipulating linking and ranking signals"
Its user-generated spam section adds "Spammy accounts on hosting services that anyone can register for," "Spammy posts on forum threads" and "Comment spam on blogs."
The same page draws the line that matters: "It's not a violation of our policies to have such links as long as they are qualified with a rel="nofollow" or rel="sponsored" attribute." In other words, a free profile or comment link is fine because it is nofollow, and it is fine for the same reason it does little for rankings. See our toxic backlinks guide for when old free links are worth worrying about. Usually they are not.
Are nofollow free links worthless?#
No, for three reasons.
First, nofollow is a hint. Google's September 2019 announcement says sponsored, ugc and nofollow "are treated as hints about which links to consider or exclude within Search," and nofollow became a crawling and indexing hint "as of March 1, 2020." Google may still use them. You can't count on it.
Second, people click links. A helpful Stack Overflow answer or a Wikipedia citation can send readers who later link from their own sites. That second link is the one that counts.
Third, a complete profile set helps people and search engines confirm who you are. That's discovery and trust, not ranking credit.
What they shouldn't be is your link building plan. Our dofollow vs nofollow guide covers how to check the attribute on any link.
How to get free backlinks that count in 5 steps#
Step 1: reclaim the links you are already owed. Search for mentions of your brand, product and founder that don't link to you, and for links pointing at pages you've moved. Ask for the link, or the fix. This is the fastest free link there is. Our link reclamation guide has the searches.
Step 2: ask people who already know you. Partners, integrations, suppliers, customers, associations, investors and podcasts. These are editorial links on relevant sites, and you only have to ask. The new websites guide lists who to start with.
Step 3: answer journalists. HARO still runs as a free newsletter, and a quote that runs earns a link from a publication. Our HARO guide covers where they went and how to answer.
Step 4: publish one page worth citing, then pitch it. An original number, a free tool or a template gives a stranger a reason to link. Then pitch it to resource pages, pages with broken links and writers covering the topic. Free in money, not in time.
Step 5: contribute where communities reward it. Answer questions on Stack Overflow, Hacker News or niche forums with real expertise, and link only when your page is the best answer. Some of these leave contributor links plain. More important, the people reading them write blogs.
Steps 2 to 4 are mostly email. GenLink's backlink agent finds sites already writing about your topic, pitches your page from your own domain and follows up, so the free links that count get asked for every day.
What the top results get wrong#
We read the top seven organic results for "free backlinks" on 9 October 2026. One timed out and is counted as a no.
- 3 of 7 present a list of free backlink sites, and all 3 say those sources pass value. None of the 3 mentions that most of them are nofollow.
- 1 of 7, Respona, says it plainly: "Most directory citations and social profile links are nofollow by default."
- 2 of 7 link to Google's own documentation. 5 of 7 warn about penalties.
- 3 of 7 sell a link building tool or service directly.
One list advised answering your own forum thread "from another account." That is the "Spammy posts on forum threads" Google describes.
The limits of this evidence#
One page per platform, fetched on one day. Platforms can treat trusted users differently, and we did not test accounts with high reputation. Fourteen popular sources blocked our requests. The SERP count came from a search tool, not a logged-in Google results page. A nofollow tag tells you what the platform asked Google to do, not what Google did.
Earn the one that counts#
Free backlinks come in two kinds: links you place yourself, which platforms and Google mostly discount, and links someone chooses to give you, which cost nothing but effort. Spend an hour on profiles for discovery. Spend the rest of your time on reclaimed mentions, relationships, journalists and one page worth citing.
Stop filling in forms that hand out nofollow links. Put one agent on your own domain to pitch the sites that decide for themselves, and spend your hours on the page they will cite.
Frequently asked questions#
Are free backlink generator tools safe? No. Google's link spam examples include "Using automated programs or services to create links to your site." At best the links are nofollow. At worst they are the pattern its spam systems are built to ignore.
Should my business still be listed in directories? Yes, where customers actually look: your industry body, your chamber, the main local directories for your area. Treat them as listings for people. Bulk submission to hundreds of directories is the "Low-quality directory" pattern.
Do Web 2.0 backlinks still work? Not as a ranking tactic. A blog you set up on Blogger or WordPress.com only to link to yourself is the "low-value content" Google lists, however plain the link is.
How many free backlinks do I need? There is no number. Count referring domains on the pages you want to outrank, then go after links you would still want if Google ignored every nofollow tag. See how to get more backlinks for the full set of tactics.
