Developer marketing and DevRel glossary
A plain-English glossary of the release-marketing and developer-relations terms you keep seeing: DevRel, B2D, build in public, changelog, release notes, PMM, GTM, GEO, AEO, DX, and more, each with a short, quotable definition.
What this solves
Someone keeps encountering developer-marketing and DevRel jargon and wants clear, quotable definitions of the core terms in one place.
How S2P helps
Walk away able to define the core developer-marketing and DevRel terms precisely, and understand how they fit together into the release-marketing loop.
Key takeaways
- DevRel is the trust-building function; developer marketing is the broader practice of reaching developers as a market.
- B2D is its own motion: developers evaluate tools by trying them, not by reading ads.
- Build in public, changelogs, and release notes are the raw material of release marketing.
- GEO and AEO are the newer disciplines of being cited by AI answer engines, not just ranked by search.
Section 1
How to use this glossary
Developer marketing borrows jargon from marketing, DevRel, product, and SEO at once, which makes it confusing fast. This is the plain-English reference for the terms that actually matter.
This field sits at the intersection of several disciplines, so the vocabulary is a mash-up. You will hear classic marketing terms like GTM and PMM next to DevRel-native ideas like developer advocacy and DX, next to newer search and AI terms like GEO and AEO. People often use these loosely, which makes conversations slippery. The definitions below are written to be precise and quotable: one sentence you could drop into a doc or a slide without rewriting it.
The terms are grouped alphabetically into a few sections so the post stays scannable, not because the groups mean anything. If you are new to the space, read it top to bottom once; the terms reference each other and the order roughly builds up the picture. If you are looking for one definition, jump to the section for its first letter. Where a term connects to the release-marketing loop this product is built around, the definition says so, because that is the through-line tying these concepts together.
A note on honesty: some of these terms are genuinely contested, and where that is true the definition flags it rather than pretending there is one settled answer. DevRel in particular means different things at different companies. The goal here is a useful, defensible working definition for each term, not a claim that ours is the only correct one.
- Each term gets one short, quotable definition you can reuse.
- Terms are grouped alphabetically only for scannability.
- Connections to the release-marketing loop are called out where they exist.
- Contested terms are flagged rather than oversimplified.
Section 2
Terms: A to D
The foundational vocabulary, from the audiences and acronyms to the core trust-building functions.
These are the terms you hit first when you start in developer marketing: who the audience is, what the motion is called, and the functions that own the developer relationship.
- AEO (Answer Engine Optimization): the practice of structuring content so AI answer engines and chat assistants quote it accurately when responding to a user's question.
- B2D (Business-to-Developer): a go-to-market motion where the developer is the buyer or the decisive evaluator, and adoption happens by trying the product rather than by responding to ads.
- Build in public: the practice of openly sharing a product's progress, decisions, metrics, and releases as you go, turning the building process itself into ongoing marketing and community.
- Bottom-up adoption: a growth pattern where individual developers adopt a tool first and usage spreads upward into teams and eventually a paid company-wide decision, the opposite of top-down enterprise sales.
- Changelog: a chronological, mostly complete record of notable changes to a project, written for users and developers who want to know exactly what changed in each version.
- Community: the network of users, contributors, and advocates around a product, and the function responsible for nurturing it through forums, chat, events, and support.
- Content marketing: earning attention and trust by publishing genuinely useful material such as guides, docs, and tutorials, rather than buying attention through ads.
- Conversion rate: the share of people at one stage who move to the next desired action, for example visitors who sign up or free users who upgrade.
- CTA (Call to Action): the specific next step a piece of content asks the reader to take, such as start free, read the docs, or book a demo.
- Developer advocacy: the DevRel discipline of representing developers' interests inside the company and the company's tools to developers, usually through demos, talks, content, and feedback loops.
- Developer marketing: the practice of reaching developers as buyers and users through credible, technical, low-pitch content and experiences rather than traditional advertising.
- DevRel (Developer Relations): the function that builds trust between a company and the developer community through advocacy, education, documentation, community, and feedback, distinct from but adjacent to marketing.
- DX (Developer Experience): the overall quality of a developer's interaction with a product, from the docs and API design to onboarding speed and error messages, treated as a first-class thing to design.
Section 3
Terms: E to L
The funnel, the search-and-AI disciplines, and the go-to-market vocabulary.
This middle stretch covers how people find you, the metrics that describe the funnel, and the cross-functional motions that ship a product to market.
- Engagement: the measurable interaction a post or piece of content earns, such as clicks, replies, reactions, and shares, used as a proxy for whether it resonated.
- Evangelism: an older name for developer advocacy, emphasizing enthusiastic public promotion of a technology, now often folded into the broader DevRel function.
- Funnel: the staged path from a stranger discovering you to becoming an active, paying user, commonly framed as awareness, consideration, conversion, and retention.
- GEO (Generative Engine Optimization): the practice of making your content the source that generative AI tools cite and summarize, the AI-era counterpart to ranking in classic search.
- GTM (Go-to-Market): the cross-functional plan and motion for how a product reaches its market, covering positioning, channels, pricing, and the teams that execute it.
- Growth: the function and mindset focused on systematically increasing acquisition, activation, retention, and revenue, often through experimentation and instrumentation.
- Hacker News: a developer-heavy community and news site where a well-received Show HN post can drive meaningful, high-intent traffic to a dev tool, but only for genuinely useful, non-promotional launches.
- ICP (Ideal Customer Profile): a precise description of the customer a product is best for, used to focus messaging, targeting, and qualification.
- KPI (Key Performance Indicator): the specific, measurable metric a team commits to moving, chosen to reflect whether the work is actually succeeding.
- Lead: a person or account that has shown enough interest, for example by signing up or requesting a demo, to be worth a follow-up.
- Lifecycle marketing: the practice of sending the right message at the right stage of a user's journey, from onboarding through activation, expansion, and re-engagement.
Section 4
Terms: M to R
The product-marketing roles, positioning, and the release-marketing vocabulary at the heart of this product.
Here are the terms most central to release marketing: the roles that own messaging, the way you describe your product against the alternatives, and the artifacts a shipping team produces.
- Messaging: the consistent set of words and claims a company uses to describe what it does and why it matters, designed so different people repeat the same clear story.
- MQL (Marketing Qualified Lead): a lead that has met a defined bar of interest or fit, signaling it is worth marketing's continued attention or a handoff to sales.
- Onboarding: the guided first experience that gets a new user from sign-up to their first real moment of value as quickly as possible.
- Positioning: the deliberate choice of how you want your product to be understood relative to alternatives, including who it is for and what category it competes in.
- PMM (Product Marketing Manager): the role that owns positioning, messaging, launches, and competitive intelligence, sitting between product, marketing, and sales.
- PLG (Product-Led Growth): a strategy where the product itself drives acquisition, activation, and expansion, typically through a free tier or trial that delivers value before any sales conversation.
- Release marketing: the practice of turning every meaningful product release into channel-native distribution, so the roadmap becomes the editorial calendar and growth compounds with each version.
- Release notes: a curated, user-facing summary of what a release delivers and why it matters, written to highlight value rather than to list every commit like a full changelog.
- Retention: the share of users who keep coming back over time, widely treated as the truest signal of real product value.
- Roadmap: the planned sequence of what a product team intends to build, which doubles as a preview of future release-marketing material.
Section 5
Terms: S to Z
Search, the launch surfaces, and the remaining funnel vocabulary.
The last stretch covers how content gets found, the public surfaces where launches happen, and a few funnel terms that round out the picture.
- SEO (Search Engine Optimization): the practice of structuring and writing content so search engines rank it well for the queries your audience actually types.
- SERP (Search Engine Results Page): the page of results a search engine returns for a query, where your title and description compete for the click.
- Show HN: a Hacker News post format for sharing something you made, which rewards genuine, working, non-promotional projects and can drive a burst of high-intent developer traffic.
- SQL (Sales Qualified Lead): a lead that sales has reviewed and accepted as worth active pursuit, a stage further along than an MQL.
- Time to value: how long it takes a new user to reach their first meaningful outcome with a product, a key driver of activation and retention.
- Top of funnel: the awareness stage where people first encounter you, before they have evaluated or committed to anything.
- TOFU, MOFU, BOFU: shorthand for top, middle, and bottom of funnel, used to describe where a piece of content or a lead sits in the journey.
- Voice and tone: the consistent personality and register a brand writes in, so its posts sound recognizably like the same company across every channel.
- Word of mouth: organic recommendation between developers, often the single most trusted and effective acquisition channel for dev tools.
Section 6
How these terms connect in practice
A glossary is more useful when you can see how the words assemble into a working motion. Here is the through-line.
Most of these terms describe one loop seen from different angles. A B2D company practices developer marketing, which a DevRel team executes through advocacy, content, and community. The product ships releases, which produce changelogs and release notes, which release marketing turns into channel-native posts. Those posts move people through the funnel, from top of funnel awareness to a conversion, and good DX and onboarding turn that conversion into retention. The same story, told in the vocabulary of whichever function you are standing in.
The newer terms, GEO and AEO, change where the discovery half happens. SEO and the SERP still matter, but a growing share of developers ask an AI assistant rather than scroll results, so being the source an answer engine cites is its own discipline now. The practical upshot is that clear, factual, well-structured content, the kind a good changelog or release post already is, is also what gets quoted by AI. The disciplines reinforce each other rather than competing.
For a release-driven team, the punchline is that you already generate the raw material for most of this. Every release is a proof point, every changelog entry answers a real question, and every significant pull request is a small story. Release marketing is the discipline of not letting that material die in GitHub, and the rest of this glossary is the vocabulary teams use to talk about doing it well.
- B2D and developer marketing name the market; DevRel names the function that serves it.
- Releases produce changelogs and release notes, the raw material of release marketing.
- The funnel terms describe the journey those posts move people through.
- GEO and AEO are the new discovery layer where clear, factual content wins.
FAQ
Questions this article answers
What is DevRel?
DevRel, short for developer relations, is the function that builds trust between a company and the developer community through advocacy, education, documentation, community, and feedback loops. It overlaps with marketing but is distinct: where marketing reaches developers as a market, DevRel focuses on being credible and useful to them. The exact scope varies by company, which is why the term is often contested.
What is B2D?
B2D stands for business-to-developer, a go-to-market motion where the developer is the buyer or the decisive evaluator. Unlike traditional B2B selling, B2D adoption happens by trying the product, reading the docs, and seeing it work, rather than by responding to ads or a sales pitch. It rewards credible, technical, low-pitch content over promotion.
What is the difference between a changelog and release notes?
A changelog is a chronological, mostly complete record of notable changes per version, written for people who want to know exactly what changed. Release notes are a curated, user-facing summary that highlights what a release delivers and why it matters, written for value rather than completeness. Release marketing distributes both, but release notes are usually closer to what a social post is built from.
What are GEO and AEO?
GEO, generative engine optimization, is the practice of making your content the source that generative AI tools cite and summarize. AEO, answer engine optimization, is closely related and focuses on structuring content so AI answer engines quote it accurately. Both are the AI-era counterparts to classic SEO, and clear, factual content like a good changelog or release post is exactly what they reward.
What is build in public?
Build in public is the practice of openly sharing a product's progress, decisions, metrics, and releases as you build, turning the building process itself into ongoing marketing and community. For a team that ships through GitHub, the release is a natural recurring trigger for build-in-public posts, which is why it pairs so well with release marketing.
What does PMM stand for?
PMM stands for product marketing manager, the role that owns positioning, messaging, launches, and competitive intelligence. A PMM sits between product, marketing, and sales, translating what was built into a clear story about who it is for and why it matters. In a release-marketing context, the PMM often defines the messaging that the release posts are written against.
