notice Image alt text is keyword-stuffed (repetition / low variety)

Rule images.alt_stuffed · Images · 1 occurrence(s)

  • https://www.ilmatieteenlaitos.fi/ultraviolettisateily — 1 image(s) have keyword-stuffed alt text — the same word repeated several times, or a long low-variety keyword list. Google's image guidance asks for short, descriptive alt text, not keyword lists; rewrite it to describe the image.

notice Image filename is generic/auto-generated (missed image-search signal)

Rule images.generic_filename · Images · 1 occurrence(s)

  • https://www.ilmatieteenlaitos.fi/suojautuminen-salamalta — 1 image(s) use a generic/auto-generated filename (e.g. IMG_1234.jpg, photo1.png, a bare UUID). Google reads the filename as a signal of image content, so rename files descriptively (hyphen-separated words) before upload.
