Why Your Image SEO Only Doing Alt Tags Is Not Enough

Image SEO Alt text alone is far from enough: Alt can only help search engines understand image content, but Google Image ranking also depends on file names, contextual content, structured data, image dimensions, loading speed and 20+ other factors. For example, research shows that the matching degree between page-related text and image theme can affect approximately 30% of image ranking weight. Only by simultaneously optimizing Alt, file names, compression speed, and page semantics can images more easily gain stable traffic.
