A meta tag de descrição é importante para SEO? [fechadas]

Question

Um número surpreendentemente grande de websites NÃO possui uma meta tag description :

<meta name="description" content="This is a description of our website" />

Isso significa que a meta tag description não é importante para SEO, ou os webmasters desses sites são incompetentes?

Eu fiz esta pergunta para obter ajuda sobre a decisão de adicionar uma metatag de descrição a um site que estou criando.

De moz.com:

Meta description tags, while not important to search engine rankings, are extremely important in gaining user click-through from SERPs. These short paragraphs are a webmaster’s opportunity to advertise content to searchers and to let them know exactly whether the given page contains the information they're looking for.

Google announced in September of 2009 that neither meta descriptions nor meta keywords factor into Google's ranking algorithms for web search. Google uses meta descriptions to return results when searchers use advanced search operators to match meta tag content, as well as to pull preview snippets on search result pages, but it's important to note that meta descriptions do not to influence Google's ranking algorithms for normal web search.
