    • Page description, each page should have a no more than 150 characters and can accurately reflect the content of the page description tag.
<meta name="description" content="150 words" />

<meta name="robots" content="index,follow" /><!-- all:文件将被检索,且页面上的链接可以被查询; none:文件将不被检索,且页面上的链接不可以被查询; index:文件将被检索; follow:页面上的链接可以被查询; noindex:文件将不被检索; nofollow:页面上的链接不可以被查询。 -->
    • Page redirection and Refresh: The number within the content represents the time (in seconds) that is refreshed after a few minutes. If the URL is added, it is redirected to the specified Web page (search engines can be automatically detected and easily punished by the engine as misleading).
<meta http-equiv="refresh" content="0;url=" />

Mobile devices
    • Viewport: Can optimize the display of mobile browser. If it is not a responsive web site, do not use Initial-scale or disable scaling.
      Most of the 4.7-5-inch devices have a viewport width of 360px;5.5 inch set to 400px;iphone6 set to 375px;ipone6 plus set to 414px.
<meta name="viewport" content="width=device-width, initial-scale=1.0,maximum-scale=1.0, user-scalable=no"/><!-- `width=device-width` 会导致 iPhone 5 添加到主屏后以 WebApp 全屏模式打开页面时出现黑边 -->
    1. Width: widths (values/device-width) (range from 200 to 10,000, default to 980 pixels)
    2. Height: Altitude (Value/device-height) (range from 223 to 10,000)
    3. Initial-scale: Initial zoom ratio (range from >0 to 10)
    4. Minimum-scale: The minimum scale to allow the user to zoom
    5. Maximum-scale: Allows the user to zoom to the maximum scale
    6. User-scalable: Whether the user can manually indent (no,yes)
    7. Minimal-ui: You can minimize the upper and lower status bar when the page loads. (deprecated)

Note that many people use initial-scale=1 to non-responsive websites, which makes the site render at 100% width, and the user needs to manually move the page or zoom. If you use User-scalable=no or maximum-scale=1 with initial-scale=1 at the same time, users will not be able to zoom in/out of the page to see all the content.
