SEO Dictionary: Terms Starting with “Z”

1. Zero-Click Result
A zero-click result refers to a search engine result that provides an answer to a query directly on the search engine results page (SERP) without requiring users to click through to a website. Examples include featured snippets, knowledge panels, and instant answers. Optimizing content to appear as a zero-click result can enhance visibility and drive traffic.

2. Zoom Usability
Zoom usability refers to how well a website or web content performs when users zoom in or out on various devices, such as smartphones and tablets. Good zoom usability ensures that content remains readable and accessible, which is important for both user experience and SEO, as search engines prioritize mobile-friendly sites.

3. Z-Index
The Z-index is a CSS property that determines the stack order of elements on a web page. It is used to manage which elements appear in front of or behind others. Proper use of the Z-index ensures that important content is not obscured by other elements, which can improve user experience and SEO by making the content more accessible.

4. Zeigarnik Effect
