What does it mean?
An illegible font size issue happens when the text on a webpage is too small to read comfortably, especially on mobile devices.
Google’s Mobile Usability guidelines state that the minimum recommended font size for body text is 16px. Anything smaller forces users to zoom in or strain their eyes, creating a poor user experience.
🚨 Why is it important for SEO?
Why is it important for SEO?
Mobile Friendliness → Google uses mobile-first indexing, so text readability directly affects rankings.
User Experience → Small fonts increase bounce rates since users leave if they can’t read easily.
Core Web Vitals Impact → Poor readability lowers engagement metrics like Time on Page and Interaction to Next Paint (INP).
Accessibility → Text that’s too small creates issues for visually impaired users, reducing compliance.
✅ How to Fix It
✅ How to Fix It
Set a base font size of at least 16px for body text.
Use relative units (em, rem) instead of fixed pixels for better responsiveness.
Ensure proper line height (1.4–1.6× font size) for readability.
Check contrast ratios to make sure text is not just bigger, but also clear.
Test on mobile devices → Make sure text scales properly.
