📱 What is Font Loading?
Font loading refers to the process by which web fonts are fetched and displayed on a web page. Efficient font loading is crucial in mobile SEO as it impacts the time it takes for a page to become visually complete, affecting user experience and search engine rankings.
⭐ Why is Font Loading Important in Mobile SEO?
Optimizing font loading is essential because poor font performance can lead to delays and cause text to appear late or incorrectly. This negatively affects user experience, increases bounce rates, and can diminish your site's SEO performance on mobile devices.
⚙️ How Does Font Loading Work?
- A web page requests a font from a font provider or server.
- The font is downloaded concurrently with other page resources.
- Once downloaded, the browser uses the font to render text, replacing default or fallback fonts.
- Browser strategies like 'font-display' influence how text appears before the font is fully loaded.
📌 Examples of Font Loading Techniques
- Using 'font-display: swap' to ensure text is visible during font loading.
- Preloading fonts for faster delivery with link rel='preload'.
- Self-hosting fonts to reduce third-party requests and improve load times.
✅ Best Practices for Font Loading
- Utilize 'font-display' property to control font loading behavior.
- Limit the number of font weights and styles to reduce loading time.
- Leverage browser caching for fonts to avoid continuous reloads on repeat visits.
- Consider accessible fallback fonts for better user experience during load time.
⚠️ Common Font Loading Mistakes to Avoid
- Relying solely on external font providers, increasing load times.
- Not specifying fallback fonts, resulting in unstyled or hidden text.
- Ignoring character subset optimization, leading to excessive data request sizes.
- Failure to test font performance on various mobile network speeds.
