Image Alt Text

Text describing an image for accessibility and image search.

Overview

Image Alt Text is standard vocabulary SEO and digital marketing teams use to align on one meaning. Text describing an image for accessibility and image search. On-page and content signals tell search systems what a page is about and whether it satisfies intent. In day-to-day work, teams reference this when auditing, writing briefs, reviewing SERPs, and explaining results to stakeholders. A precise shared definition reduces rework between content, technical, and analytics owners. This guide separates Image Alt Text from closely related ideas in the related terms section; the focus here is clarifying signals search engines and users evaluate. Track a small set of KPIs weekly, compare against a documented baseline, and tie changes to specific ship dates, not single-day noise in Search Console or rank trackers.
