PWA
In order for your PWA icon to look optimised on Android devices, you should use the maskable icons format: these ensure that the image fills all available space and does not just leave a white background.
If a page has no maskable icon support, SeoChecker will notify it:
If you want to pass the audit, you should set up a web app manifest that needs to have an icons array: this last one should contain one object with a purpose property that includes the value maskable or any maskable.
{ … "icons": [ … { "src": "path/to/maskable_icon.png", "sizes": "196x196", "type": "image/png", "purpose": "any maskable" } ] … }
