Link & URL Standards

Last Edited: 2026-06-30 11:46

Anchor Text & Aria-Labels

The text content and description attributes that define the link destination for screen readers and search crawlers.

• Input: The text within the <a> tag and the aria-label="..." attribute.
• Standards:
  1. Keyword Context: Anchor text must feature descriptive, target-focused keywords rather than generic "click here" or "learn more" text.
  2. Aria-Label Fallback: When design demands generic visual buttons (e.g. "Book Now"), you must use an aria-label to supply search engines and accessibility tools with link destination context.
     • Example: <a href="/schedule" aria-label="Book AC repair services in Phoenix">Book Now</a>
  3. Visual Style: Links must be visually distinct (underlined by default in text block sections).

URL Slugs

The text identifier representing the path of the webpage resource.

• Input: The URL subdirectory path string (slug) following the domain name.
• Standards:
  1. Clean Formatting: Use lowercase characters, separate words with hyphens, and strip out dates or grammatical "stop words" (the, a, and).
  2. Hierarchical Subdirectories: Structure directories (e.g., /service-area/city/service/) to establish topical grouping when search volume supports the division.

Linkable Elements

The interactive page elements that are permitted to function as link containers.

• Input: Parent containers enclosing the <a> tags.
• Standards:
  1. Approved Elements: Navigation links must only be wrapped around Images, Buttons, and Text.
  2. Prohibited Elements: Do not wrap links around heading elements (Ref: Headings) or elements that trigger hover actions.
  3. Whole Section Wraps: Avoid wrapping entire layout blocks or sections in links unless an aria-label is defined to structure the link destination.

External Links

Links that navigate the user away from the local website to a third-party domain.

• Input: The <a> element with non-local URLs.
• Standards:
  1. New Tab Requirement: All external links must open in a new browser tab or window.
  2. Security & Performance Attributes: Must include target="_blank" paired with rel="noopener" (or rel="noopener noreferrer") to prevent performance drag and protect against tab-nabbing vulnerabilities.
     • Example: <a href="https://example.com" target="_blank" rel="noopener">Visit Reference</a>
