Review Questions

• How does alt text contribute to both web accessibility and search engine optimization?
  • Alt text plays a dual role by enhancing web accessibility for visually impaired users through descriptive content that screen readers can interpret. At the same time, it aids search engine optimization by providing context to images, which helps search engines index them effectively. This not only improves user experience but also increases the chances of images appearing in search results, driving more traffic to the website.
• In what ways can poorly written alt text negatively affect a website's SEO strategy?
  • Poorly written alt text can hinder a website's SEO strategy by failing to provide adequate descriptions that search engines need to index images properly. If the alt text is irrelevant or too vague, it will not enhance the site's keyword relevance or image search visibility. Additionally, if alt text is overly stuffed with keywords or completely absent, it can lead to penalties from search engines and ultimately lower site rankings.
