Free backlink sources: relevant platforms, real contributions and a 30-day plan

What are free backlinks useful for?

A backlink is a link from a page on another site to a page of yours; in the source it is an ordinary <a href> element. For a reader it is a path: out of an article or a profile and onto your work. For search engines, links are also one way to discover new pages and to understand how pages relate to each other. That is why the word “backlink” is so often paired with a ranking promise; this article makes no such promise.

The first distinction is how a link comes to exist. When someone reads your page and chooses to cite it, that is an editorial, earned link. When you type your own website into your own GitHub, Behance or Gravatar profile, you created the link yourself. That is legitimate and can be useful, but it is nobody else’s endorsement; counting a link on your own profile as “earned” is fooling yourself. Most of the platform tables in this article describe the second kind, links you create on your own profiles and projects; the seventh section is about the first kind, links you deserve.

Most profile links carry a nofollow or ugc marker; the next section explains what those markers mean. Even so, such links can offer three concrete benefits. The first is referral traffic: a developer looking at your package on PyPI or a designer browsing your project on Behance can click through to your site. The second is discovery: people find your work where they already look, independently of where a page ranks in search results. The third is brand and entity consistency: when the same name, the same short bio and the same web address appear in several trustworthy places, people and systems associate that work with one person or organization more easily. I am not claiming that this is a measured “Google entity score” or a ranking gain; I am only saying that consistency reduces confusion.

“Free” here means you pay no placement fee; it does not mean no effort. Every profile needs maintenance, every post has to give the reader something real, and every community has rules. Opening an account on a platform is easy; the hard part is leaving something there that genuinely helps a developer, a designer or a reader.

Let me state the scope up front: for this article I did not open an account on any platform, publish any link or message anyone. I only inspected public pages and official sources on 11 October 2026. The “observed link” column in the tables records a single field seen on a single page that day; it is not a platform’s general rule or a promise to you.

Link types and Google’s boundary

Google’s link spam policy draws the boundary plainly: buying or selling links to influence ranking, excessive link exchanges, automated link creation, low-quality directories, optimized forum or comment links and low-value link content are violations. Paid advertising and sponsorships must be marked with suitable qualifiers. A service calling itself “free” does not change that: private blog networks (PBNs) or mass-submission packages do not become acceptable because they cost nothing.

The second source is Google’s document on qualifying outbound links. An ordinary editorial link needs no special qualifier. Use sponsored for paid placements and ugc for user contributions; nofollow is also accepted for paid links. Links marked this way are generally not followed, yet the destination can still be discovered elsewhere. In other words, the marker says how the publisher of the link describes the relationship; it does not stop your page from being found through other sources.

noopener, noreferrer, me and external are tokens of a different kind. noopener and noreferrer govern security and privacy behaviour between the page that opens a link and the page that is opened; me declares an identity relationship (this profile is mine); external marks the link as external. None of them promises any transfer of ranking. By the same token, a link that carries no attribute at all promises no ranking benefit either: the absence of an attribute is not a guarantee.

You do not have to guess what a link really carries. Right-click it, choose “Inspect”, and read the rel attribute of the <a> element in the developer tools. The console line below lists the links with absolute (http) addresses on a page; using getAttribute lets us tell a missing attribute (null) from an empty one ("").

01console.table(02  [...document.querySelectorAll('a[href^="http"]')].map((a) => ({03    href: a.href,04    rel: a.getAttribute("rel"), // null = no rel attribute, "" = empty attribute05  })),06);

A rel value describes only that single link. Whether a page is indexed is a separate matter: a noindex robots meta tag or an X-Robots-Tag header applies to the whole page. A redirect (for instance a link that goes through a tracking address) is another mechanism and must not be confused with rel. Being indexed and being visible in search results are Google’s decisions; no attribute guarantees either. The Packagist sample shows the confusion well: the observed author link has the rel value nofollow noopener external noindex ugc; the noindex in it is not a standard link token and does not create a page-level noindex.

Make it a habit to read a rel value token by token. In the Modrinth sample the “View source” link has the value noopener nofollow ugc: noopener limits the new tab’s access to the source page (security), nofollow says the publisher does not vouch for the link, and ugc says it comes from user content. Three tokens answer three separate questions; none says “this link contributes this much to your ranking”. The same way of reading applies to noreferrer noopener ugc on Product Hunt or noopener noreferrer nofollow me on Open Collective.

On the same platform, different fields behave differently. In the PyPI sample the Documentation link in the project description carries nofollow, while the Repository link in the sidebar carries noopener. That is why the tables never say “this platform is nofollow”; they say “on this page, in this field, on 11 October 2026, this rel value was observed”. Platforms can change their markup; inspect the field you intend to use yourself before you publish your own profile.

Developer and open-source platforms

For developers, the most natural sources of a “free link” are the places where the things you already produce get published: a repository, a package, a documentation site, a model card. The first group in this article has 19 platforms, and what they share is this: a link only makes sense next to a real artifact.

The diagram above shows six groups with selected example names; it draws no ranking or authority. The choice is determined not by how famous a platform is but by where your audience is and what you can leave there as a contribution.

Three concrete examples show why markup has to be read field by field. In the GitHub sample profile the website field carries rel="nofollow me": nofollow says the publisher does not vouch for the link, while me is an identity token saying that the profile and the target site belong to the same person. In the PyPI sample package the Documentation link in the project description carries nofollow and the Repository link in the sidebar carries noopener: two fields on one page, two different markups. On Packagist the author website link has the value nofollow noopener external noindex ugc; a registry can combine its own link policy into several tokens in a single field.

In package registries the rule is clear: on PyPI, NuGet, Packagist, RubyGems, pub.dev or Modrinth, an entry should be opened together with an artifact that genuinely works. An empty package, or a project that carries nothing but your web address, both clashes with the community’s rules and runs against the spirit of Google’s link spam policy; on top of that you occupy a namespace for no reason. The right approach is the reverse: first write a small but useful library, dataset or tool; prepare its license, README and release notes; and name your website only where it helps the user, in the documentation or homepage field.

From Turkey’s point of view the opportunity is often language and context. A Python package with Turkish examples or localization, a Hugging Face repository with Turkish NLP datasets and demos, translation contributions for the WordPress community in Turkey, a localization library for Flutter developers: these fill a local gap on a global platform. If you write the README and docs in both Turkish and English you serve two audiences at once; the Turkish part should be a faithful counterpart of the English one, carrying the same information.

I split the tables below into three groups: general profile and community spaces first, then code and documentation projects, and finally package registries and game/mod platforms that require a real package or artifact. The “Yes” in the free-entry column covers two different strengths of evidence. In some rows the official page explicitly offers a $0 plan or a free account (GitHub, GitLab, Linktree, GoodFirms and others). In other rows, as with package and community registrations, there is an open registration or publishing workflow and the official material shows no paid step; that is weaker evidence and does not mean “a free plan exists”. I do not know whether the owners of the sample pages use a paid or legacy plan, so do not assume that a field on a sample page will exist on every free account. Before you follow any step, confirm the field you intend to use on your own account.

Product launches and startup communities

Product-launch platforms make sense once your product is genuinely usable. Product Hunt, Indie Hackers and SaaSHub are the three examples inspected here; all three have a “Visit website” link on the product page, but three different markups were observed: noreferrer noopener ugc in the Product Hunt sample, nofollow noopener in the Indie Hackers sample, and an empty rel="" attribute in the SaaSHub sample. Reading the three platforms as one rule would be misleading.

What does being ready mean? A working release, honest screenshots (the real interface, no invented numbers), a short and accurate value proposition, and a founder who answers questions on launch day. Because Product Hunt’s launch FAQ prohibits company accounts, you need a personal maker account. Vote rings, bought votes, asking friends for en-masse votes and copying another site’s description all strain both community rules and Google’s link policy.

On Indie Hackers, join the community first: share progress notes, answer other people’s questions, do not invent revenue figures. SaaSHub’s product submission entry is public; a free entry and paid promotion are separate things, and you should not use its bulk-directory promotion tool. If a Turkish SaaS product has no English pages, launch texts and screenshots, none of these three platforms will bring it a real audience; prepare that first.

Write three things down before launch. First, one sentence on who the product helps and with which problem: if it is a Turkish product, phrase that sentence in English too, because the audience of these platforms is international. Second, a demo or trial path that genuinely works; a product nobody can try quickly draws criticism. Third, the weeks after launch: answering incoming questions, fixing bugs and keeping the product page current. A launch lasts a day, but the impression you leave that day (accurate screenshots, honest limits, quick replies) determines how the page reads for months.

You often hear names such as BetaList, AlternativeTo and Crunchbase. In this research I could not verify their free-entry terms or their real link behaviour; so I do not recommend them as free backlink sources and have left them out of the tables. Do not copy a claim that you cannot verify with your own observations.

Portfolios, businesses and local visibility in Turkey

The difference between a good creative portfolio and a thin link profile is what is on the page. A real project on Behance with process images, your role, client permission and project descriptions gives a visitor what they need to decide; a profile holding nothing but your name and web address does not. The same goes for Linktree and Carrd: a one-page link hub works as a single destination for your social profiles, but a structure that chains dozens of sites together or lengthens the redirect chain adds no value. Keep your primary pages on your own domain.

On Speaker Deck an original talk, on Gravatar a consistent identity tied to your email: both make the same author identity visible across your TR and EN sites. me nofollow noreferrer was observed in the Gravatar sample; identity consistency is not a guarantee of a Google ranking or an entity score. A copied project, scraped slides or an empty PDF will not make a link worth anything.

A simple rule is enough for consistency across your profiles: choose one main address and use the same name, the same short bio and the same address on every profile. If you have both TR and EN sites, write the bio with the same information in both languages; do not add or drop details. Use me verification only for profiles that genuinely belong to you. Consistency makes it easier for people and systems to match you with the right person; it is housekeeping, not a ranking trick.

GoodFirms is an option for a genuine service company: it requires ownership and contact details, a portfolio and truthful client reviews, and listing acceptance is not automatic. Fake or incentivized reviews cross the line of both the platform and Google. If you are a freelancer, do not try to look like a company.

Flickr is the most restricted example in the table: free accounts cannot post Commercial content. So Flickr is not a free advertising listing for a commercial business but a conditional route for original, noncommercial photography. Read the rules on Flickr’s free account limits page.

The source most often named for local visibility is Google Business Profile. The official Turkish page confirms that a free profile is offered, but the eligibility condition is explicit: only businesses that meet their customers in person are eligible, and online-only businesses are not. As a software developer or a remote agency, first establish whether you genuinely qualify; if you do not, do not add a fake address or a fictitious place. In this research I could not check the rel value of the business website link on Maps; so I left it out of the tables and make no promise about its link behaviour.

The same goes for Bing Places, Apple Business Connect, Yandex Business and Foursquare: in this research I did not verify current country support, the free scope or link behaviour; check them on their own official pages. For chamber-of-commerce or association memberships I also found no verified free route, so I name none.

Knowledge, community and publishing platforms

Platforms such as Wikipedia, Wikidata and Zenodo are the part of this guide that demands the most care, because there a link is a by-product of an independent knowledge standard and you cannot place it as you please. On Wikipedia independent editors decide on inclusion; the conflict-of-interest rules ask you to disclose an interest in a subject and to propose edits instead of making changes directly, and the external links guideline limits what may be added. On Wikidata, items must meet the notability criteria and follow the conflict-of-interest policy. I do not teach these sites as targets to fill for links; the table only shows the observed markup (mw:ExtLink nofollow and nofollow in the samples).

Zenodo is for genuine research or educational output; a marketing upload is out of scope, and receiving a DOI is not a guarantee of a link, a citation or a ranking. OpenStreetMap is not an SEO directory: adding fictitious places or links to the map harms the community. These platforms are places where your contribution serves the knowledge itself; making your website visible can only be a by-product.

On discussion platforms the criterion is simple: participation comes before the link. On Discourse, help with real support or development topics; on Mastodon, follow the rules of the server you choose and set up a relevant profile; on Hacker News, write a Show HN only for an original project that people can try, and take part in the discussion. On Ekşi Sözlük registration is free, but authorship approval is separate and the right to write is not guaranteed; become an approved author where required, give a relevant reference and do not hide your affiliation. Bought accounts, planted reviews, vote requests and repeated promotion are not tolerated on any platform. The markup in the samples varies too: the Hacker News Show HN sample carries nofollow, the Mastodon bio link carries noopener, and the Discourse Meta sample has no rel; do not generalize any of these to your own community.

Open Collective is for a genuine community or open-source initiative: it needs a transparent purpose, a team and, where applicable, financial records. Although a $0 organization entry is documented, fiscal hosting, payouts and transaction fees can cost money; and sponsorship is not a way to buy ranking credit.

WordPress.com, Tumblr, Blogger and Substack offer a free start to publishing; what makes a link valuable on these platforms is that the content is original. A four-paragraph post on a free subdomain that is merely a summary of someone else’s site gains no one anything. Satellite blogs set up for link manipulation and duplicated copies of the same text count as low-value link content. If you republish an article that appeared elsewhere, set the canonical address explicitly. On Substack a free publisher account is not free access to every article; paid subscriptions involve separate platform and payment fees.

When choosing among the four publishing platforms, look at your audience first. If you already have newsletter readers, Substack may make sense; Tumblr for visual and creative work; WordPress.com or Blogger for a lasting blog on a free subdomain. Publishing on your own site is often the best option; these platforms are a way of carrying the content to another audience, not a replacement for your own site. If you want to publish in more than one place, add a different angle for each audience instead of copying the text verbatim, and state the canonical address.

Create an asset worth citing

Free profiles have a limit: they describe you in your own voice. The honest way to earn a link is to produce something useful enough that someone else can choose to point to it. It does not have to be “content”; it can be a calculator, a dataset, a guide or a template. What matters is that you state the method, the sources, the limits and the update date plainly.

The loop in the diagram has six steps: a useful asset, a clear method and sources, an appropriate audience, the publisher’s independent editorial decision, referrals and feedback, and maintenance. The dashed branch is there on purpose: a link may not be added. No step promises an automatic ranking or a conversion rate.

Two tools on this site illustrate the approach; neither is proof of success on its own, and I have found no evidence that they have earned links so far. The Turkish Inflation Calculator is an example of a useful asset in a local language: transparent CPI sources, dates, method and limitations can make it worth citing on a resource page. The Turkish Test Data Generator is a Turkish developer resource: it shows clearly synthetic data and reproducible usage, with no real personal data and no unsupported compliance promise. I did not separately test the numeric output of either tool for this article.

A concrete exercise: improve the inflation calculator’s explanation and its source and update notes, then find a genuinely relevant economics-education resource page. Explain which reader problem the tool solves and leave the decision to add a link to the editor. For the test data generator, write a useful Turkish test-fixture tutorial and suggest it only to a relevant developer teaching resource. These are proposed actions; they do not describe contacts made, placements accepted or any existing backlink.

The asset itself also has to be accessible. The robots.txt Generator produces rules describing which paths crawlers may reach; robots.txt does not create backlinks itself. The llms.txt Generator is an optional machine-readable documentation aid; it is not a Google requirement or a ranking guarantee. The Schema generator helps you describe your asset accurately; structured data does not guarantee rich results, links or rankings. The AI Crawler Checker inspects the crawl and HTML material you supply, locally; it is not a measurement or guarantee of AI visibility.

Once your asset is ready, these are the ways in which links are actually earned; each one is one-to-one, relevant and optional:

• Broken-link replacement: only when your asset genuinely fits in place of the broken resource; tell the editor the broken address and why yours fits.
• Unlinked brand mentions: if you find an article that mentions you without linking, send a courteous, optional request to add one; do not insist.
• Resource pages: suggest your asset to the author of a relevant resource list; the editor decides whether it fits.
• Expert quotes and digital PR: answer a journalist’s question with something you genuinely know.
• Podcast guesting: be named as a useful resource in the show notes.
• Original guest contributions selected by the editor: an original piece for publication off your own site; the publisher decides on the link.

The free entry of journalist-expert matching services such as Qwoted, Featured and Source of Sources was verified: Qwoted’s basic free plan comes with two pitches a month and a two-hour delay, Featured’s free plan is now described as daily AI-usage allowances, and Source of Sources offers free email queries. What I did not verify is whether a link on a publisher’s site will result from any of them, or how it would be marked. So the entry may be free, but there is no link promise; off-topic pitches can lead to your account being removed. Keep Featured’s paid backlink and automated pitching features out of this white-hat workflow as well.

Sponsorship, a donation to a university or financial support for an open-source project are not free link tactics; they are paid relationships. Disclose a paid placement and have it marked with the appropriate sponsored or nofollow; never demand a followed link.

A practical 30-day plan

The plan below is a planning target, not a results report. The output beside each window should be reviewable, and no window should carry a link-count target. Record inputs (what you did) and outcomes (what happened) separately: a request may be declined or end in a mention without a link; that is not a failure but information.

A neutral example of a personalized pitch message (fill the square brackets with real details; never send it in bulk): “Hi [name], I built a small tool for [specific reader need] discussed in [specific section]. [URL] explains the method, sources and limits. If it fits your readers, you’re welcome to consider it; whether to link is entirely your editorial decision. No reply is needed if it is not a fit.”

Adapt the windows to your own situation. In the first window a spreadsheet is enough: for each profile, the name, address, which field, which rel and the date of the last check. The second window could be, with this article’s example, writing the source and update notes of the inflation calculator or the tutorial for the test data generator; making one asset good is worth more than leaving three half-done. In the third window your target should be a few places whose rules you have read, not a quota: read the community’s own guide before every contribution. In the fourth window the main matter is timing: if you have sent a suggestion, wait long enough for a reply and follow up courteously at most once. The fifth window is for writing the outcome honestly; if no link came but your asset has improved, the month was not wasted.

Keep your suggestions in a log that is simple enough to account for. Each row should hold the date, the target page, why that page seemed relevant to you, a summary of the message you sent, the rules of the page or publisher (does it accept suggestions, which contact channel), the reply and the outcome. In the outcome column write only what you know: “no reply”, “declined”, “mention without a link”, “link added (date)”. Such a log is the only way to show yourself honestly after a month what worked; it also stops you from writing to the same person twice.

This message makes no ranking, persuasion or reciprocity promise; the link is optional and a reply is not required. Sending the same text to hundreds of people is mass sending; personalize each message with a detail from the page you read, or do not send it at all.

Measurement and the never-do list

The things worth measuring are simple. Keep inputs (suggestions sent, contributions made) apart from outcomes (accepted, declined, a mention without a link, a link), and never count links on profiles you created yourself as “earned”. The links report in Search Console is not an exhaustive or real-time ledger; the list you see can be incomplete.

• Qualified referral visits: visitors who come from a platform and do something meaningful on the page.
• Engagement: pages read, resources downloaded, tools used.
• Inquiries: messages real people send you.
• Accepted citations: links and mentions an editor gave of their own accord, with dates.
• Asset maintenance: when the method, source and update notes were last refreshed; broken links.

Measurement gains meaning from a baseline: in the first three days note today’s referral visits and existing mentions, and on day thirty put the same figures side by side. The cause of a change is often not a link but a season, a news item or a social media post; so do not draw big conclusions from small numbers. A monthly review is enough: fix broken links, refresh notes that have gone stale and keep the few channels that still work.

The most common situation in practice is a site offering a “paid guest post” or a “link package”. A paid placement is advertising or sponsorship and must be marked sponsored or nofollow; if it guarantees a followed link, stay away, because that is exactly what the policy prohibits. In an unpaid guest contribution the publisher chooses the topic and the link itself; you do not dictate it.

The list below is the dark side of every method above. None of the eight items is up for debate.

Principle over a numeric quota: a few relevant contributions that genuinely add something beat a large number of empty links. If a link still offers a benefit to someone who does not know you, you are on the right path.
