Desplaza la tabla hacia los lados
Dónde somos más débiles: one page and only img tags are checked, with no file weight, picture or CSS backgrounds; there is no alt generation, batch processing or alt quality scoring.
Cuándo elegir PromoPilot: When you want to see in a minute where a page lacks alt text, dimensions and lazy loading, and which pictures are still in old formats. For writing alt texts in bulk you need a plugin or an AI tool, and for file weight a speed audit.
