如何使右轨 SEO 中的主要内容变得友好？
我的网站设计有三个栏：左侧的导航，中间的用户生成的讨论（液体），以及右侧栏的主要编辑块（无广告）。因此，我发布的一篇文章会出现在右栏的顶部，而用户评论将出现在中心栏。
我希望搜索引擎将右栏内容视为主要内容，因此每个页面的元描述将与右栏相关。
是否可以通过 SEO 友好的方式做到这一点？
[注：一家 SEO 咨询公司向我的老板暗示，网络爬虫只“关心中心栏”，如果元信息与中心栏内容不一致，他们将忽略该页面]
My site design has three rails: navigation on the left, user generated discussions in the center (liquid), and a primary editorial block in the right rail (no advertising). So, an article would be published by me and appear at the top of the right rail, and user comments would appear in the center rail.
I want search engines to see the right rail content as the primary content, and so the meta description for each page would be related to the right rail.
Is it possible to do this in an SEO friendly way?
[Note: an SEO consulting firm have implied to my boss that web crawlers only "care about the center rail", and if the meta information disagrees with center rail content they will ignore the page]

搜索引擎无法像人类用户那样查看页面。搜索引擎只能看到页面的 html 代码，因此无法区分左栏、中栏或右栏。然而，他们确实知道页面的页眉、正文和页脚是什么。
当涉及页面正文时，搜索引擎倾向于为靠近顶部的文本提供更多相关性。因此，如果您的 html 源代码顶部有一个文本块，可以使用 CSS 将其视觉移动到页面下方的某个位置，并且仍然（可能）比其他文本块更相关。
但是，无法向搜索引擎指定页面的“主要内容”是什么。搜索引擎根据许多不同的页面信号确定页面与关键字的相关性，因此您应该关注这些信号。
至于元描述，你的老板应该更仔细地选择SEO咨询公司，因为他们推荐的实际上是无稽之谈。例如，元描述仅（最终）被 Google 用于在搜索结果中为您的页面生成片段。它们对于排名没有任何价值。
以下是直接来自 Google 的有关元描述的两个 SEO 事实：Seo 事实 NO.3、Seo 事实 NO.4
Search engines cannot see the page the way human users do. Search engines see just the html code of the page, so they cannot distinguish between left, center or right rails. They do, however, have a sense of were the header, the body and the footer of a page is.
When it comes to the body of a page, search engines tend to give more relevance to text which closer to the the top. So if you can have a block of text at the top of your html source, move it visually with CSS somewhere lower on the page, and still (probably) remain more relevant than other blocks of text.
However, there is no way to specify to search engines what your "primary content" of a page is. Search engines determine the relevancy of a page in relation to keywords based on a lot of different on-page signals, so you should focus on those.
As for the meta description, your boss should choose the SEO consulting firms more carefully, as what they recommended is actually a nonsense. Meta descriptions are only used (eventually) by Google (for example) to generate the snippet for your pages in search results. They have no value when in comes to rankings.
Here's two SEO facts regarding meta descriptions that come directly from Google: Seo Fact NO.3, Seo Fact NO.4
页面上可见内容的定位是使用 CSS 处理的。
有多种不同的方法可用，从使用
float到position:absolute等。出于 SEO 目的，只要您的文章内容出现，就没有单一的最佳方法最接近标记，位于其他“rails”或“columns”之前。Positioning of visible content on a page is handled using CSS.
There's a number of different approaches available from using
floattoposition:absoluteetc. For SEO purposes, there's no single-best approach, as long as you have your article content appear closest to the<body>tag, before the other "rails" or "columns".
