What is Site Architecture?
How pages connect: hubs, categories, and link paths from the homepage down. Good architecture keeps priority pages shallow, clustered by topic, and reachable through descriptive links.

Crawl Depth
Clicks from the homepage to reach a page. Deep pages get crawled less often and inherit less prominence; priority content belongs within a few hops with internal-link support.
Internal Link
A link between pages on the same site, guiding discovery and distributing relevance. Controlled tests show deliberate internal-link changes lifting organic traffic 5–25%, and underlinked priority pages are a standard audit finding.
Topic Cluster
A pillar page surrounded by interlinked subtopic pages. Clusters make coverage legible to crawlers and readers at once, and internal links bind them into one structure.
Technical SEO
The crawling, indexing, rendering, and performance work that lets search engines reach, understand, and serve your pages. It covers directives, architecture, speed, and structured data rather than words on the page.
Crawling
How search-engine bots discover pages by following links, sitemaps, and directives. If a URL is never crawled, it cannot be indexed no matter how good its content is.
Crawl Budget
The number of pages a search engine will crawl on a site in a given period, driven by server capacity and demand signals. Large or slow sites must spend it on indexable, valuable URLs.
