How TheSiteFuse checks "Mobile compatibility (responsive)"
The viewport tag in the HTML code tells mobile browsers to adapt the page to screen size. Without it, the site displays as a shrunken desktop version on phones, requiring zooming to read anything.
Why it matters
Real-world impact of "Mobile compatibility (responsive)"
Over 60% of web traffic comes from mobiles. Google prioritises the mobile version of sites ("Mobile First Indexing"). A non-responsive site is penalised in results and drives visitors away.
