提问by Johnno Nolan

There seems to be huge number of meta tagsyou can set. I'm guessing that some of them are more important than others.

您似乎可以设置大量元标记。我猜其中一些比其他的更重要。

What are the most important metatags to supply and why?

要提供的最重要的元标签是什么？为什么？

Do I even need meta tags? (looking at the stackoverflow homepage there are none)

我什至需要元标记吗？（查看stackoverflow主页，没有）

I realize this question is old, but it's still a top google hit, so I thought I would give an updated answer that includes popular social media sites.

我意识到这个问题很老，但它仍然是谷歌热门话题，所以我想我会给出一个更新的答案，其中包括流行的社交媒体网站。

I generally have four groups of meta info:

我通常有四组元信息：

Regular Meta Info- used by search engines and browsers

常规元信息- 由搜索引擎和浏览器使用

<title>{{pageTitle}}</title>
<meta charset="utf-8"><!-- html5 version of http-equiv="Content-Type"... -->
<meta name="description" content="{{description}}">
<meta name="keywords" content="{{keywords}}">
<link rel="author" href="https://plus.google.com/{{googlePlusId}}" />
<link rel="canonical" href="{{pageUrl}}" />

Facebook Meta Info- used by Facebook when someone shares your url

Facebook 元信息- 当有人分享您的网址时由 Facebook 使用

<meta property="og:url" content="{{pageUrl}}">
<meta property="og:image" content="{{imageUrl}}">
<meta property="og:description" content="{{description}}">
<meta property="og:title" content="{{pageTitle}}">
<meta property="og:site_name" content="{{siteTitle}}">
<meta property="og:see_also" content="{{homepageUrl}}">

Google+ Meta Info- used by Google+ when someone shares your url

Google+ 元信息- 当有人分享您的网址时由 Google+ 使用

<meta itemprop="name" content="{{pageTitle}}">
<meta itemprop="description" content="{{description}}">
<meta itemprop="image" content="{{imageUrl}}">

Note: you don't really need these, Google+ will fall back to the Open Graph tags that Facebook uses.

注意：您实际上并不需要这些，Google+ 将退回到 Facebook 使用的 Open Graph 标签。

Twitter Meta Info- used by Twitter when someone shares your url

Twitter 元信息- 当有人分享您的网址时由 Twitter 使用

<meta name="twitter:card" content="summary">
<meta name="twitter:url" content="{{pageUrl}}">
<meta name="twitter:title" content="{{pageTitle}}">
<meta name="twitter:description" content="{{description}}">
<meta name="twitter:image" content="{{imageUrl}}">

I'll use my same answer from this question:

我将使用与这个问题相同的答案：

A few years back, meta tags were important to search engine optimization. However, they've been abused and are generally ignored by almost all search engines (including Google, Yahoo and Live search. Excuse me: Bing).

几年前，元标签对搜索引擎优化很重要。然而，它们已经被滥用并且几乎被所有搜索引擎（包括谷歌、雅虎和实时搜索。对不起：必应）忽略。

The most important tags for SEO that you can include in your (X)HTML are the <title>and <meta name="description"...>tags.

您可以在 (X)HTML 中包含的最重要的 SEO 标签是<title>和<meta name="description"...>标签。

• <title>should generally be what you'd want the search engine to name your page in it's listing.
• <meta name="description"...>can sometimes give the search engine a basic idea of how to describe your page when indexing it.

• <title>通常应该是您希望搜索引擎在其列表中为您的页面命名的名称。
• <meta name="description"...>有时可以让搜索引擎了解如何在索引页面时描述您的页面。

However, using these two tags will not necessarily make a difference in increasing your site's visibility on a search engines listings. For more information on that aspect, Google has a nice section on SEOon their site.

但是，使用这两个标签不一定会提高您网站在搜索引擎列表中的可见度。有关这方面的更多信息，谷歌在他们的网站上有一个很好的SEO 部分。

Themost important meta tag you should use is:

您应该使用的最重要的元标记是：

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

adjusted to suit. This ensures that, if you ever need to transmit that HTML document via something other than a web server (e.g. working on it locally, sending as an attachment), the user-agent is aware of its mime-type and character set. Just make sure your server headers agree.

调整以适应。这确保，如果您需要通过 Web 服务器以外的其他方式传输该 HTML 文档（例如在本地处理它，作为附件发送），则用户代理知道其 MIME 类型和字符集。只要确保您的服务器标头同意即可。

The best SEO is a website that meets the needs of its target users effectively. To do that you need to have a site that has something in it that people can use, want, or need. This is value and its the most important thing. It can be anything from good articles to entertaining video or a useful download. Tags support good content but cant replace it for SEO. If the content is good enough no tags are needed. Trust me when I say, if your site has something, anything people want or need, that they can't get just anywhere, your site will do well in all regards, tags or no tags. If your site is boring and has no value it will fail, tags or no tags.

最好的 SEO 是一个能有效满足目标用户需求的网站。为此，您需要有一个网站，其中包含人们可以使用、想要或需要的内容。这是价值，也是最重要的事情。它可以是任何东西，从好文章到有趣的视频或有用的下载。标签支持好的内容，但不能代替 SEO。如果内容足够好，则不需要标签。相信我，如果您的网站有一些东西，人们想要或需要的任何东西，他们在任何地方都无法获得，那么您的网站在所有方面都会做得很好，有标签或没有标签。如果您的网站很无聊并且没有价值，它将失败，标记或没有标记。

the description metatag will be used by google as description of your site. I think it's the most important.

谷歌将使用描述元标记作为您网站的描述。我认为这是最重要的。

I think that the verify-v1 meta is important. It makes possible to use Google Webmaster tool

我认为 verify-v1 元很重要。可以使用 Google 网站管理员工具

GoogleBot ignores meta information only trusting the page content itself rather than content descriptors. So, the usefulness of certain tags may be limited.

GoogleBot 忽略元信息，仅信任页面内容本身而不是内容描述符。因此，某些标签的用处可能会受到限制。

回答by Jona

I would make sure you have a title, description, keyword, and revisit-after tag in your web pages. Although Google doesn't weigh keyword tag as much, it may still be used by smaller search engines.

我会确保您的网页中有标题、描述、关键字和 revisit-after 标签。尽管 Google 对关键字标签的权重不那么高，但它仍可能被较小的搜索引擎使用。
