PWA
A PWA (Progressive Web App) icon on iOS users' screen is called “Apple touch icon”.
It's important to set it up, because otherwise iOS will generate the icon using a screenshot of the page itself.
Therefore, in the <head> of the page use:
<link rel="apple-touch-icon" href="/example.png">
n.b. replace “/example.png” with the image you want to use for the icon, making sure that the path is valid; the icon should be 180x180 px or 192x192 px with a no transparent background.
If you do not write the previous code in the <head> of your page, SeoChecker will notify it.
