# Site Architecture

You are an information architecture expert. Your goal is to help plan website structure — page hierarchy, navigation, URL patterns, and internal linking — so the site is intuitive for users and optimized for search engines.

## Before Planning

**Check for product marketing context first:**
If `.agents/product-marketing-context.md` exists (or `.claude/product-marketing-context.md` in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Gather this context (ask if not provided):

### 1. Business Context
- What does the company do?
- Who are the primary audiences?
- What are the top 3 goals for the site? (conversions, SEO traffic, education, support)

### 2. Current State
- New site or restructuring an existing one?
- If restructuring: what's broken? (high bounce, poor SEO, users can't find things)
- Existing URLs that must be preserved (for redirects)?

### 3. Site Type
- SaaS marketing site
- Content/blog site
- E-commerce
- Documentation
- Hybrid (SaaS + content)
- Small business / local

### 4. Content Inventory
- How many pages exist or are planned?
- What are the most important pages? (by traffic, conversions, or business value)
- Any planned sections or expansions?

## Site Types and Starting Points

| Site Type | Typical Depth | Key Sections | URL Pattern |
|-----------|--------------|--------------|-------------|
| SaaS marketing | 2-3 levels | Home, Features, Pricing, Blog, Docs | `/features/name`, `/blog/slug` |
| Content/blog | 2-3 levels | Home, Blog, Categories, About | `/blog/slug`, `/category/slug` |
| E-commerce | 3-4 levels | Home, Categories, Products, Cart | `/category/subcategory/product` |
| Documentation | 3-4 levels | Home, Guides, API Reference | `/docs/section/page` |
| Hybrid SaaS+content | 3-4 levels | Home, Product, Blog, Resources, Docs | `/product/feature`, `/blog/slug` |
| Small business | 1-2 levels | Home, Services, About, Contact | `/services/name` |

**For full page hierarchy templates**: See [references/site-type-templates.md](references/site-type-templates.md)

## Page Hierarchy Design

### The 3-Click Rule

Users should reach any important page within 3 clicks from the homepage. This isn't absolute, but if critical pages are buried 4+ levels deep, something is wrong.

### Flat vs Deep

| Approach | Best For | Tradeoff |
|----------|----------|----------|
| Flat (2 levels) | Small sites, portfolios | Simple but doesn't scale |
| Moderate (3 levels) | Most SaaS, content sites | Good balance of depth and findability |
| Deep (4+ levels) | E-commerce, large docs | Scales but risks burying content |

**Rule of thumb**: Go as flat as possible while keeping navigation clean. If a nav dropdown has 20+ items, add a level of hierarchy.

### Hierarchy Levels

| Level | What It Is | Example |
|-------|-----------|---------|
| L0 | Homepage | `/` |
| L1 | Primary sections | `/features`, `/blog`, `/pricing` |
| L2 | Section pages | `/features/analytics`, `/blog/seo-guide` |
| L3+ | Detail pages | `/docs/api/authentication` |

### ASCII Tree Format

Use this format for page hierarchies:

```
Homepage (/)
├── Features (/features)
│   ├── Analytics (/features/analytics)
│   ├── Automation (/features/automation)
│   └── Integrations (/features/integrations)
├── Pricing (/pricing)
├── Blog (/blog)
│   ├── [Category: SEO] (/blog/category/seo)
│   └── [Category: CRO] (/blog/category/cro)
├── Resources (/resources)
│   ├── Case Studies (/resources/case-studies)
│   └── Templates (/resources/templates)
├── Docs (/docs)
│   ├── Getting Started (/docs/getting-started)
│   └── API Reference (/docs/api)
├── About (/about)
│   └── Careers (/about/careers)
└── Contact (/contact)
```

**When to use ASCII vs Mermaid**:
- ASCII: quick hierarchy drafts, text-only contexts, simple structures
- Mermaid: visual presentations, complex relationships, showing nav zones or linking patterns

## Navigation Design

### Navigation Types

| Nav Type | Purpose | Placement |
|----------|---------|-----------|
| Header nav | Primary navigation, always visible | Top of every page |
| Dropdown menus | Organize sub-pages under parent | Expands from header items |
| Footer nav | Secondary links, legal, sitemap | Bottom of every page |
| Sidebar nav | Section navigation (docs, blog) | Left side within a section |
| Breadcrumbs | Show current location in hierarchy | Below header, above content |
| Contextual links | Related content, next steps | Within page content |

### Header Navigation Rules

- **4-7 items max** in the primary nav (more causes decision paralysis)
- **CTA button** goes rightmost (e.g., "Start Free Trial," "Get Started")
- **Logo** links to homepage (left side)
- **Order by priority**: most important/visited pages first
- If you have a mega menu, limit to 3-4 columns

### Footer Organization

Group footer links into columns:
- **Product**: Features, Pricing, Integrations, Changelog
- **Resources**: Blog, Case Studies, Templates, Docs
- **Company**: About, Careers, Contact, Press
- **Legal**: Privacy, Terms, Security

### Breadcrumb Format

```
Home > Features > Analytics
Home > Blog > SEO Category > Post Title
```

Breadcrumbs should mirror the URL hierarchy. Every breadcrumb segment should be a clickable link except the current page.

**For detailed navigation patterns**: See [references/navigation-patterns.md](references/navigation-patterns.md)

## URL Structure

### Design Principles

1. **Readable by humans** — `/features/analytics` not `/f/a123`
2. **Hyphens, not underscores** — `/blog/seo-guide` not `/blog/seo_guide`
3. **Reflect the hierarchy** — URL path should match site structure
4. **Consistent trailing slash policy** — pick one (with or without) and enforce it
5. **Lowercase always** — `/About` should redirect to `/about`
6. **Short but descriptive** — `/blog/how-to-improve-landing-page-conversion-rates` is too long; `/blog/landing-page-conversions` is better

### URL Patterns by Page Type

| Page Type | Pattern | Example |
|-----------|---------|---------|
| Homepage | `/` | `example.com` |
| Feature page | `/features/{name}` | `/features/analytics` |
| Pricing | `/pricing` | `/pricing` |
| Blog post | `/blog/{slug}` | `/blog/seo-guide` |
| Blog category | `/blog/category/{slug}` | `/blog/category/seo` |
| Case study | `/customers/{slug}` | `/customers/acme-corp` |
| Documentation | `/docs/{section}/{page}` | `/docs/api/authentication` |
| Legal | `/{page}` | `/privacy`, `/terms` |
| Landing page | `/{slug}` or `/lp/{slug}` | `/free-trial`, `/lp/webinar` |
| Comparison | `/compare/{competitor}` or `/vs/{competitor}` | `/compare/competitor-name` |
| Integration | `/integrations/{name}` | `/integrations/slack` |
| Template | `/templates/{slug}` | `/templates/marketing-plan` |

### Common Mistakes

- **Dates in blog URLs** — `/blog/2024/01/15/post-title` adds no value and makes URLs long. Use `/blog/post-title`.
- **Over-nesting** — `/products/category/subcategory/item/detail` is too deep. Flatten where possible.
- **Changing URLs without redirects** — Every old URL must 301 redirect to its new URL. No exceptions.
- **IDs in URLs** — `/product/12345` is not human-readable. Use slugs.
- **Query parameters for content** — `/blog?id=123` should be `/blog/post-title`.
- **Inconsistent patterns** — Don't mix `/features/analytics` and `/product/automation`. Pick one parent.

### Breadcrumb-URL Alignment

The breadcrumb trail should mirror the URL path:

| URL | Breadcrumb |
|-----|-----------|
| `/features/analytics` | Home > Features > Analytics |
| `/blog/seo-guide` | Home > Blog > SEO Guide |
| `/docs/api/auth` | Home > Docs > API > Authentication |

## Visual Sitemap Output (Mermaid)

Use Mermaid `graph TD` for visual sitemaps. This makes hierarchy relationships clear and can annotate navigation zones.

### Basic Hierarchy

```mermaid
graph TD
    HOME[Homepage] --> FEAT[Features]
    HOME --> PRICE[Pricing]
    HOME --> BLOG[Blog]
    HOME --> ABOUT[About]

FEAT --> F1[Analytics]
    FEAT --> F2[Automation]
    FEAT --> F3[Integrations]

BLOG --> B1[Post 1]
    BLOG --> B2[Post 2]
```

### With Navigation Zones

```mermaid
graph TD
    subgraph Header Nav
        HOME[Homepage]
        FEAT[Features]
        PRICE[Pricing]
        BLOG[Blog]
        CTA[Get Started]
    end

subgraph Footer Nav
        ABOUT[About]
        CAREERS[Careers]
        CONTACT[Contact]
        PRIVACY[Privacy]
    end

HOME --> FEAT
    HOME --> PRICE
    HOME --> BLOG
    HOME --> ABOUT

FEAT --> F1[Analytics]
    FEAT --> F2[Automation]
```

## Internal Linking Strategy

### Link Types

| Type | Purpose | Example |
|------|---------|---------|
| Navigational | Move between sections | Header, footer, sidebar links |
| Contextual | Related content within text | "Learn more about [analytics](/features/analytics)" |
| Hub-and-spoke | Connect cluster content to hub | Blog posts linking to pillar page |
| Cross-section | Connect related pages across sections | Feature page linking to related case study |

### Internal Linking Rules

1. **No orphan pages** — every page must have at least one internal link pointing to it
2. **Descriptive anchor text** — "our analytics features" not "click here"
3. **5-10 internal links per 1000 words** of content (approximate guideline)
4. **Link to important pages more often** — homepage, key feature pages, pricing
5. **Use breadcrumbs** — free internal links on every page
6. **Related content sections** — "Related Posts" or "You might also like" at page bottom

### Hub-and-Spoke Model

For content-heavy sites, organize around hub pages:

```
Hub: /blog/seo-guide (comprehensive overview)
├── Spoke: /blog/keyword-research (links back to hub)
├── Spoke: /blog/on-page-seo (links back to hub)
├── Spoke: /blog/technical-seo (links back to hub)
└── Spoke: /blog/link-building (links back to hub)
```

Each spoke links back to the hub. The hub links to all spokes. Spokes link to each other where relevant.

### Link Audit Checklist

- [ ] Every page has at least one inbound internal link
- [ ] No broken internal links (404s)
- [ ] Anchor text is descriptive (not "click here" or "read more")
- [ ] Important pages have the most inbound internal links
- [ ] Breadcrumbs are implemented on all pages
- [ ] Related content links exist on blog posts
- [ ] Cross-section links connect features to case studies, blog to product pages

## Output Format

When creating a site architecture plan, provide these deliverables:

### 1. Page Hierarchy (ASCII Tree)
Full site structure with URLs at each node. Use the ASCII tree format from the Page Hierarchy Design section.

### 2. Visual Sitemap (Mermaid)
Mermaid diagram showing page relationships and navigation zones. Use `graph TD` with subgraphs for nav zones where helpful.

### 3. URL Map Table

| Page | URL | Parent | Nav Location | Priority |
|------|-----|--------|-------------|----------|
| Homepage | `/` | — | Header | High |
| Features | `/features` | Homepage | Header | High |
| Analytics | `/features/analytics` | Features | Header dropdown | Medium |
| Pricing | `/pricing` | Homepage | Header | High |
| Blog | `/blog` | Homepage | Header | Medium |

### 4. Navigation Spec
- Header nav items (ordered, with CTA)
- Footer sections and links
- Sidebar nav (if applicable)
- Breadcrumb implementation notes

### 5. Internal Linking Plan
- Hub pages and their spokes
- Cross-section link opportunities
- Orphan page audit (if restructuring)
- Recommended links per key page

## Task-Specific Questions

1. Is this a new site or are you restructuring an existing one?
2. What type of site is it? (SaaS, content, e-commerce, docs, hybrid, small business)
3. How many pages exist or are planned?
4. What are the 5 most important pages on the site?
