TL;DR
The best backlink sources for API companies are the places developers already work: integration partner pages and app marketplaces, API directories, open source repositories and package registries, tutorials built on your docs, technical publications, developer communities, and Q&A sites. Many of these links are nofollow or ugc, and they still matter, because they bring developers who adopt the product, signal real usage, and build the brand mentions AI assistants pick up. Pair them with followed editorial links from technical publications and partners, and point everything at docs and integration pages, not just the homepage.
Why API companies need a different backlink mix
A typical SaaS link building plan leans on marketing blogs, business publications, and "best tools" lists. That still has a place, but for an API or developer tool company it misses where most of the relevant links live. Developers discover tools through docs, repositories, community threads, and tutorials written by other developers. Those are the pages that rank for technical queries, and they are the pages your buyers trust.
Three things make the API backlink mix different:
- Your docs are your most linkable asset. Developers link to a specific reference page or guide, not to a landing page, so most of your links should point deep into the site.
- Many of the best sources are user generated. Repositories, forums, and Q&A sites mark links nofollow or ugc, so the profile naturally contains more of them than a typical SaaS site.
- Relevance is easy to judge. A link from a page about building with webhooks is obviously relevant to a webhooks API. A link from a general business site rarely is, whatever its authority score.
If you want the general playbook first, start with how to get backlinks for a SaaS company. This post covers the sources that are specific to API and developer tool companies.
Best backlink sources for API companies
These are source types, not a list of named sites to buy from. The right specific targets depend on your language ecosystem, your integrations, and the problems your API solves.
Integration partner pages and app marketplaces
Every platform you integrate with probably has a partner directory, an integrations page, or an app marketplace. Listings on those pages are some of the most relevant links an API company can earn, because they sit on a site your users already rely on, next to a description of exactly what your product does with theirs. Go beyond the listing: offer a co-written guide for the partner's docs or blog, a joint use case page, or a short integration tutorial they can publish. Those pages often carry followed, contextual links.
API directories and marketplaces
Public API directories and API marketplaces list APIs by category, with a description, docs link, and pricing. Some are well maintained and get real developer traffic; many are thin pages that exist to collect listings. Submit to the ones that rank for your category terms and show signs of real use, such as recent listings and active reviews, and skip the rest. Treat directories as a foundation layer, not a strategy.
Open source repositories and package registries
Your SDKs, client libraries, CLI tools, and example apps all live on code hosts and package registries such as GitHub, npm, and PyPI. Each one has a README and a package page that can link to your docs and homepage. Most of these platforms mark user content links as nofollow, but they are where developers evaluate whether your API is easy to use. Keep READMEs current, link to the exact quickstart and reference pages, and make sure every official package points back to your site.
Open source also earns links indirectly. A useful library, a well documented example, or a small tool that solves a common problem gets referenced in other projects' docs, blog posts, and "awesome" lists.
Tutorials built on your docs
When developers write tutorials that use your API, they link to your docs as a matter of course. You can encourage this: publish clear quickstarts that are easy to build on, answer authors' questions quickly, and share the best tutorials from your own channels so writing about your API gets noticed. The links that result are contextual and highly relevant, because each one sits inside working code that uses your product. If you run a paid community writing program, treat it as content and reach rather than link building: links in tutorials you paid for should carry a sponsored or nofollow attribute.
Technical publications and engineering blogs
Developer focused publications and the engineering blogs of other tech companies publish deep technical articles and accept contributed pieces from practitioners. A guest article written by one of your engineers about a real problem (scaling rate limits, designing idempotent endpoints, handling webhook retries) earns followed editorial links and credibility that marketing content cannot. These pitches only work when the article teaches something specific, with code, and mentions your product only where it genuinely fits.
Customer engineering blogs
Customers who build something interesting on top of your API often write about it on their own engineering blogs. Ask your customer success and developer relations teams to flag good stories, then offer to help with review, diagrams, or promotion. A "how we built it" post from a customer is one of the most credible links a developer tool can have, because it is written by an actual user for other engineers.
Developer communities and forums
Communities such as Reddit, Hacker News, language specific forums, and Discord or Slack groups with public archives are where developers ask for recommendations and share what they built. Links posted there are usually nofollow or ugc, and self promotion is unwelcome in most of them. The sustainable approach is to have engineers and developer advocates participate genuinely, answer questions, and link to docs only when the docs are the best answer. A launch post that lands well can still send waves of traffic and later editorial links from people who saw it.
Q&A sites
Developer Q&A sites such as Stack Overflow rank for an enormous range of error messages and how to questions. Answer links are typically marked nofollow or ugc, but an accepted answer that links to the exact docs page solving the problem can send steady, high intent traffic for years. Monitor questions that mention your product or the problem it solves, and answer with a complete solution first and a link second.
Backlink sources at a glance
Link attributes vary by site and change over time, so treat this column as typical rather than guaranteed. Check the actual attribute on any page before you count a link.
| Source | Typical link attribute | Effort | Main value |
|---|---|---|---|
| Integration partner pages | Often followed | Low | Highly relevant links on sites your users trust |
| API directories and marketplaces | Mixed | Low | Category visibility, discovery by developers comparing APIs |
| Repositories and package registries | Usually nofollow | Low to medium | Evaluation traffic, adoption, brand mentions |
| Tutorials built on your docs | Usually followed | Medium | Contextual links to docs inside working code |
| Technical publications | Usually followed | High | Editorial authority and credibility with engineers |
| Customer engineering blogs | Usually followed | Medium | Credible proof written by real users |
| Developer communities | Usually nofollow or ugc | Medium, ongoing | Traffic spikes, awareness, later editorial links |
| Q&A sites | Usually nofollow or ugc | Low per answer | Long tail, high intent traffic to docs |
Why nofollow and ugc links still matter
A lot of the sources above produce nofollow or ugc links, and it is tempting to skip them because they do not count toward third party authority scores. As we explain in how to increase domain rating, only followed links move DR. For an API company that would be a mistake, for four reasons.
- Google treats nofollow, ugc, and sponsored as hints rather than strict rules, so these links are not automatically worthless for search.
- They bring the right people. A developer who clicks from a Q&A answer or a README is often mid build, which is about as close to activation as traffic gets.
- They create brand mentions. AI assistants and search engines learn which tools belong to a category from where they are discussed. Being named consistently in developer communities makes it easier for both to associate your product with the problem it solves.
- They make the profile look natural. A developer tool with only followed links from marketing blogs, and none from the places developers actually talk, looks odd. A mix that mirrors real usage is what a healthy profile looks like.
The point is balance. Nofollow sources build adoption and recognition; followed editorial links from partners, technical publications, and tutorials build the authority that helps your docs and product pages rank. You need both.
How to prioritize backlink sources for an API company
You will not have time to work every source at once. This order gets the most relevant links first and builds toward the harder ones.
- Audit what you already have: list every integration, official SDK, and package, and check that each partner listing and package page links to the right page on your site.
- Fill the gaps in partner listings. Ask every integration partner that does not list you yet, and offer a co-written guide to the ones that do.
- Submit to the handful of API directories that rank for your category and show real activity.
- Pick three to five docs pages that answer common problems and make them the default link targets for community and Q&A answers.
- Assign a small, recurring slot to developer community and Q&A participation, owned by an engineer or developer advocate rather than marketing.
- Pitch one technical article per month to developer publications or partner engineering blogs, written with or by an engineer.
- Ask customer facing teams to flag customers building interesting things, and offer support for a "how we built it" post.
- Track every link with its source type, attribute, and target page, so you can see which sources bring both links and sign ups.
Make your docs worth linking to
Every source above sends links to your docs, which means your docs have to be ready for them. Pages need stable URLs that will not break when you release a new API version, clear titles that match how developers search, and content that loads without client side rendering hiding it from crawlers. A link to a docs page that later returns a 404 is wasted, and so is a link to a page search engines cannot read.
We cover the technical side, including versioning, rendering, and canonical tags across versions, in technical SEO for API documentation. It is worth fixing before you scale any link building, because docs are where most of an API company's links will land.
How Chung Digital builds links for API and developer tool companies
Chung Digital focuses on SaaS, API, developer tools, and cybersecurity companies, so our outreach focuses on technical and B2B tech publishers rather than general marketing sites. Many generalist B2B link building agency programs default to business blogs; for an API company we start from the docs and integration pages that need links and look for publishers whose readers build software.
Our SaaS link building agency handles the editorial side: guest articles and niche edits on vetted, relevant sites, with content written for you, manual outreach, and an anchor text and target URL plan from the Growth tier up. The sources that depend on your own team, such as community participation, partner relationships, and open source work, stay with you, and we help you decide where they fit alongside the placements.
You approve each placement before it goes live and get a monthly report with every URL, anchor, and date. We do not promise rankings, sign ups, or AI citations, because no outside party controls any of them. What we can do is keep a steady flow of relevant, editorial links pointing at the pages developers actually use.
Frequently asked questions
Are GitHub links good for SEO?
Links in READMEs and other user content on GitHub are generally marked nofollow, so they pass little ranking credit. They are still valuable because developers evaluate your API there, and a well maintained repository earns references from other projects and articles that often are followed.
Should API companies submit to every API directory?
No. Submit to the few directories that rank for your category and show signs of real use, such as recent listings and active developer traffic. Mass submission to thin directories adds noise to your profile without bringing users.
Is it okay to pay developers to write tutorials about our API?
Yes, as long as the links are handled correctly. Paid writing programs are a common way to get good tutorials written, but Google's guidance is that links you paid for should carry a sponsored or nofollow attribute. The tutorials still bring developers and mentions; the unpaid ones other developers write on their own are where followed links come from.
Do links from developer communities help AI search visibility?
They can contribute. AI assistants learn which tools belong to a category partly from where they are discussed, and developer communities are a big part of that conversation. Nobody can guarantee a mention, but genuine presence in those threads helps.
Where should API backlinks point: docs or the homepage?
Mostly docs, integration pages, and specific guides. Developers link to the page that solves their problem, and those deep pages are often what ranks for technical queries. Branded links naturally go to the homepage.
Can a small API startup compete for links with established providers?
Yes, on narrower topics. Established providers win broad terms, but a small team with excellent docs and engineers who write about specific problems can earn links and rank for long tail technical queries the big players do not cover well.
How is link building for API companies different from general B2B link building?
General B2B link building targets business and marketing publications. API link building leans on technical sources, partners, and developer communities, points mainly at docs, and accepts a higher share of nofollow links because that is how developer platforms work.
