## What it does

The skill walks through each platform: where the ads show up, why the format works, what it costs and what limits apply. Carbon Ads is priced per impression, BuySellAds lets you buy placements straight from publishers, Reddit targets individual subreddits, and newsletters and podcasts sell sponsor slots. Typical rates and minimum spends are listed per channel as reference points, not guarantees.

A second part covers creative. The rule is blunt: say what the product does before anything else. There are examples of copy that gets dismissed and what to write instead. Reddit gets its own warning, because developers spot an ad instantly and fake organic posts get called out.

The skill does not connect to any ad account and runs nothing on its own. It is a strategy reference you read before starting a campaign and check back against later. Installation goes through `npx skills add`, which drops the skill file into your platform's directory.

# Developer Ads

## Overview

Most advertising doesn't work for developers. They use ad blockers, distrust marketing, and share bad experiences widely. But targeted advertising on developer-specific platforms—done thoughtfully—can drive qualified awareness and traffic.

This skill covers the platforms that actually reach developers, how to create ads that don't trigger immediate dismissal, and how to measure whether your spend is working.

## Why Most Ads Don't Reach Developers

### The Ad Blocker Problem

Estimates suggest 50-70% of developers use ad blockers. This makes most display advertising ineffective:

- Google Display Network: Heavily blocked
- Facebook/Instagram: Limited developer targeting
- General programmatic: Low reach, wrong audience

### Developer Ad Resistance

Even when ads reach developers, they face skepticism:

- Banner blindness is extreme
- Marketing language triggers instant dismissal
- Developers share bad ads as cautionary tales
- Trust is hard to build, easy to lose

### What Does Work

Advertising that reaches developers successfully:

- **Contextual placement**: Ads on sites developers already trust
- **Value-first messaging**: Leading with what you do, not superlatives
- **Technical credibility**: Ads that show you understand the audience
- **Native formats**: Newsletter mentions, sponsored content

## Platform-by-Platform Guide

### Carbon Ads

**What it is:** Native advertising network for developer and design websites

**Where ads appear:**
- Developer documentation sites
- Tech blogs
- Developer tools
- Open source project sites

**Why it works:**
- Non-intrusive design
- Respected by developers
- Often not blocked
- Highly contextual placement

**Costs:**
- CPM-based pricing
- Typically $2-5 CPM
- Minimum budgets vary
- Direct buys for premium sites

**Best practices:**
- Simple, text-focused creative
- Clear value proposition
- Relevant to site context
- No hype language

**Limitations:**
- Limited targeting options
- Cannot always choose specific sites
- Creative restrictions
- Availability varies

### BuySellAds

**What it is:** Marketplace for buying ads directly on websites

**Key developer placements:**
