mobile-friendly pages (defined by Google)

Google 將在行動裝置搜尋結果，加入mobile-friendly標籤。

符合以下條件會被加入標籤：

• Avoids software that is not common on mobile devices, like Flash
• Uses text that is readable without zooming
• Sizes content to the screen so users don't have to scroll horizontally or zoom
• Places links far enough apart so that the correct one can be easily tapped
