# GitHub engagement and trust signals

> This file explains how social proof and maintenance signals affect repository trust, human conversion, and discovery without overstating undocumented GitHub ranking behavior.

---

## 1. Overview

Metadata (names, topics, READMEs) provides semantic context for GitHub search and external search engines. Engagement and maintenance signals provide trust for humans and may influence discovery surfaces such as Explore, recommendations, and external search results. GitHub does not publish a complete public ranking formula, so this file distinguishes documented user-visible signals from reasonable trust recommendations.

## 2. Primary trust signals

**Recommendation:** Treat stars and forks as social proof, not guaranteed ranking levers. Stars and forks make a repository look useful and adopted. They can improve click-through and credibility when a user compares similar projects, but GitHub does not publish a deterministic formula that says a starred repository will outrank an unstarred one for every query.

**Recommendation:** Build visible contributor credibility. Public contributions, clear ownership, and recognizable maintainers help humans evaluate a repository. Graph-based reputation models such as OpenRank are useful research analogies, but they should not be described as GitHub's confirmed production ranking system unless GitHub documents that behavior.

**Recommendation:** Earn external references. GitHub repositories are indexed by standard web search engines. Links from documentation, articles, package registries, talks, or credible community discussions can help external search discovery and send qualified users to the repository. Do not claim that backlinks directly boost GitHub's internal ranking unless a source documents it.

**Recommendation:** Maintain a clear release history when the project is versioned. Using GitHub Releases to tag versions (e.g., `v1.0.0`, `v1.1.0`) shows humans that the project is maintained and gives external search engines additional stable pages to index. Do not create fake releases for projects that do not have meaningful versioned changes.

## 3. Health and maintenance signals

**Recommendation:** Manage Issue and PR hygiene. A repository with hundreds of open, unaddressed issues or pull requests can look abandoned. Aim to respond, label, close, or document triage expectations so visitors understand the maintenance state.

**Recommendation:** Ask for stars sparingly and honestly. A small call-to-action can remind satisfied users to star a useful repository. Keep it secondary to actual documentation and avoid manipulative wording.

**Recommendation:** Use continuous integration (CI) badges when they reflect real checks. Passing build badges provide quick visual proof that the codebase is tested. They help human trust and can improve conversion from visitor to user or contributor.

## 4. Anti-Patterns

### The single massive commit

**What it looks like:** Developing a project locally for three months and pushing it to GitHub in a single, massive commit labeled "initial commit." **Why it fails:** It deprives humans and tools of an activity timeline. A single commit gives little evidence of design evolution, maintenance, or project health. **What to do instead:** Initialize the Git repository locally on day one, write descriptive atomic commits as you build the project, and push regularly.
