What does a good URL look like?

Readable as a sentence fragment: protocol, clean domain, short hyphenated path stating the page's subject. Paths over parameters, no dates on undated content, lowercase throughout. If reading the URL aloud describes the page, it is right.

Do URLs affect rankings?

Modestly and indirectly: descriptive paths aid relevance and click confidence, clean structure prevents the duplicate-URL sprawl that genuinely hurts, and stability preserves accumulated equity. The big URL wins are architectural hygiene, not keyword placement.

URL

A URL is the full web address of a specific page or resource, including the protocol, domain, and path, such as the address of this glossary.

Each URL points to one resource, and changing it changes how that resource is accessed. Clean, descriptive URLs help users and search engines understand a page. They are also the unit search engines index and rank.

URL structure is information architecture made visible: a good URL states where the page lives and what it is before anyone reads the title. The rules that age well are restraint, lowercase, hyphens, no parameters where paths work, no dates unless content is dated, depth reflecting hierarchy, not folder count. Every URL is a commitment: once indexed, linked and shared, changing it costs a redirect and some equity, so structure decisions deserve more forethought than they get. Parameters that alter nothing meaningful, sorting, tracking, sessions, are the classic source of duplicate-URL sprawl.

Example

https://www.example.co.th/th/services/seo-audit/?utm_source=line#pricing decomposes into protocol, subdomain, domain, language path, page path, tracking parameter, fragment. Search engines index everything up to the parameter; the fragment never reaches the server. Half of practical technical SEO, canonicals, redirects, parameter handling, hreflang, is deciding which of these parts may vary and which must not.
