Meta (мета) теги для сайта

В данной статье представлены мета теги (meta tags) рекомендованные и не рекомендованные для размещения. Также вы сможете найти информацию о том, какие мета теги помогают лучше понимать ваши статьи ботам Facebook, Twitter, Google+ / Shema org и т.д. 

Что же такое мета теги? 

Метатеги (англ. meta tags) — (X)HTML-теги, предназначенные для предоставления структурированных метаданных о веб-странице. Как правило, указываются в заголовке (теге <head>) (X)HTML-документа. Элемент meta принимает как минимум четыре атрибута: content, http-equiv, name и scheme. Из них обязателен только атрибут content и исключение тег revisit.

Ниже представлен минимальный набор тегов для самых простых сайтов: 

<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
<title>Page Title</title>
