What is Slug?
The readable tail of a URL naming the page (/blog/what-is-byob). Short, descriptive, stable slugs survive redesigns and read well in results, shares, and AI citations.

URL Structure
Readable, stable, segmented paths that describe the page. Short descriptive slugs beat parameter strings for users, sharing, and long-term maintainability.
Site Migration
Any platform, domain, protocol, or architecture change affecting URLs. Safe migrations map every old URL, preserve signals with 301s, and monitor indexation and logs for weeks after.
URL Parameter
Query-string values (?sort=price) that create crawlable URL variants. Parameters expand URL space and slow rendering queues, so audits decide per parameter: crawl, canonicalize, or block.
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.
