Site Architecture
Site architecture is the hierarchical structure and organization of a website's pages, URLs, and navigation, determining how content is grouped, linked, and accessed by users and search engine crawlers.
Good site architecture ensures every important page is reachable within 3 clicks from the homepage, organizes content into logical categories, and distributes link equity efficiently. Flat architectures (few levels of depth) are generally better for SEO than deep ones (many levels).
Plan architecture before building: start with main categories (mapped to top navigation), subcategories (one level deeper), and individual pages. The URL structure should mirror this hierarchy: `/glossary/`, `/glossary/meta-description/`, `/tools/`, `/tools/meta-checker/`.
For programmatic SEO sites, architecture includes index pages that link to all generated pages. A glossary index page linking to 100 term pages, a tools index linking to all free tools — these serve as hubs that distribute authority and ensure complete crawlability. Indxel's site crawl maps your actual architecture and identifies structural issues.

Internal Linking
Internal linking is the practice of connecting pages within the same website using hyperlinks. It distributes link equity, establishes site hierarchy, and aids crawlability.
Hub and Spoke Model
The hub and spoke model is a content architecture pattern where a central hub page (comprehensive overview) links to multiple spoke pages (detailed subtopics), and each spoke links back to the hub.
Silo Structure
Silo structure is a website architecture pattern that groups topically related content into isolated sections (silos), with strong internal linking within each silo and minimal cross-linking between silos.
