What is developer marketing?

Developers are the audience that taught the industry to block ads. They decide what to use by installing it, reading the docs and asking peers, and they can tell within minutes whether a claim holds. Anything that reads like a pitch is skipped; anything that reads like a tutorial is read.

The numbers are blunt. 67% of developers run an ad blocker (MarketingTech News, developer ad-blocking survey) and 64% of them say it is because ads intrude (business.daily.dev/resources — why developers block most ads). Marketing that interrupts does not reach them; marketing that is useful, in the place they chose to read, does.

The other difference is who buys. In most B2B categories the buyer is a manager who evaluates through demos. For developer tools the buyer is the user: a developer adopts, the team follows, and the contract comes last. The person to convince runs the code.

• Documentation and technical content. The quickstart, the tutorials, the engineering blog. Found through search and recommended by peers; the foundation everything else points to.

• Developer communities and open source. Being present and useful where developers already talk, and being a good citizen of the projects they rely on.

• Newsletters and feeds developers subscribe to. Native placements inside the reading developers chose: the one paid channel that reaches them at scale.

• Developer relations. Advocates, talks, livestreams and community programs that put real engineers in front of other engineers.

• Conferences and events. Expensive, slow, and still where categories get defined.

Start where the product meets the developer: the docs and the quickstart. Then add distribution for what you publish, because a good post on your own blog reaches the people who already follow it. Paid search and social reach developers too, with more waste, because they target titles rather than what people build.

Not by impressions. 35% of "viewable" ads are actually looked at (Lumen / Adelaide attention research), and a developer who did look rarely acts at once. Measure what developers do next, in order: reads and follows, sign-ups, activation (a first working result), weekly use, and the share of new users who arrive through word of mouth.

Attribute over weeks, not days. A developer sees a post, reads the docs the following week, and signs up from a search on another device. A conversion pixel with view-through credit and your own user IDs sees that path; a last-click report calls it "direct" and reports the campaign as a failure.

The useful comparison across channels is cost per activated developer. A channel with cheap clicks that never activate is the expensive one.

It says something specific a developer can check. "Postgres branching for every pull request" is a campaign; "the database platform for modern teams" is a logo. It lands on a page that delivers what the card promised, ideally a quickstart or a working example rather than a form.

It runs always-on. 95% of B2B buyers are out-of-market right now (LinkedIn B2B Institute / Ehrenberg-Bass, the 95-5 rule); the campaign that reaches a developer today is remembered when the need arrives in six months only if it kept showing up. Presence beats bursts.

And it is written by someone who could use the product. Developers can tell when the copy came from marketing and the engineering team never saw it.

Usually a developer marketing lead or product marketing manager who sits between product, developer relations and growth, with engineers contributing content and advocates carrying it. The reporting line matters less than the rule that nothing ships to developers without an engineer having read it.

Small teams often start with one person who runs the docs, the blog and the paid presence together, which is fine: consistency of voice across those three matters more than headcount.
