How do you optimize images and video for Google search reputation?

Images and videos that rank for branded queries are an underused reputation asset. Optimization runs through standard mechanics applied consistently. Filenames are descriptive and brand-appropriate (not IMG_0042.jpg). Alt text reads naturally and includes the relevant entity or topic. Image and video schema (ImageObject, VideoObject) is applied wherever the asset is embedded. Captions are structured rather than ad-hoc. Image and video sitemaps are submitted to Google Search Console. Embedding happens on high-authority pages with strong surrounding context. For video, transcript content on the host page extends what Google and the AI engines can extract. The cumulative effect is that branded image and video search becomes a controlled environment rather than a free-for-all, and the assets feed Knowledge Panel imagery and AI engine visual references.
