Look at Wikipedia with styles off. See how they order their content? See how they use correct tags to label the content? These are the keys to long term success.
The most important SEO advice is to create a semantic, logical site. The content comes first and is ordered by importance. Use the correct tags, don't do tables. Then apply styles. Then apply script to make it fancy. (Like Tomas said)
Know the difference between what is content (pictures of your products) and not (your logo tiled on the background). Basically do your best to present good content in a good way. You can't game the system for long term gains.
This will give you long term placement. Most SEO companies just do tricks or links farms or worry about keywords and meta tags, so they are temporary at best. I think it is good to assume that Google works just as hard to drop that crap from it's index as the SEO marketers do to include it.
列表）以及源顶部 div 中的内容，以及不那么重要的内容（徽标、横幅、快速菜单等）确实非常重要的是需要更进一步的可访问性。 您始终可以重新排序内容在 css 中实际显示的位置。
A main concern when thinking SEO should always be usability. Make sure the mark-up is semantic, make sure the site works without javascript, css and images - in other words, make sure that 'low-level browsers' are able to read the contents of your page. Think of optimizing the site for a screen reader for the blind and visually impaired, and you will automatically cover the search engines, because that is exactly what they are - blind browsers.
A standard no-no is a table layout, mainly because it does not order the site content by relevance. To a human being reading your site, it is no problem looking two inches down instead of at the very top of your page, but the screenreader reads the code, not the visual view.
Thus, you should make sure that you have the important things - a high-level heading (preferrably <h1> or <h2>), the main menu (in a <ul> list) and the content in divs at the top of the source, and less important content (the logo, banners, quickmenus etc that aren't really crucially needed to be accessible) further down. You are always able to re-order where the stuff is actually shown in your css.

查看样式关闭的维基百科。 看看他们如何订购内容？ 看看他们如何使用正确的标签来标记内容？ 这些是长期成功的关键。
最重要的 SEO 建议是创建一个语义、逻辑站点。 内容排在第一位，并按重要性排序。 使用正确的标签，不要做表格。 然后应用样式。 然后应用脚本使其变得更漂亮。 （就像托马斯说的）
知道什么是内容（你的产品图片）和什么不是内容（你的标志平铺在背景上）之间的区别。 基本上就是尽力以好的方式呈现好的内容。 你不能为了长期利益而欺骗系统。
这将为您提供长期安置。 大多数搜索引擎优化公司只是做一些技巧或链接农场或担心关键字和元标记，所以它们充其量是暂时的。 我认为最好假设谷歌会像 SEO 营销人员努力将这些垃圾内容从其索引中删除一样努力将其纳入其中。

According to Google's patent

当认为 SEO 应该始终时，一个主要关注点是可用性。 确保标记是语义的，确保网站无需 javascript、css 和图像即可运行 - 换句话说，确保“低级浏览器”能够读取页面的内容。 考虑为盲人和视障人士优化屏幕阅读器的网站，您将自动覆盖搜索引擎，因为它们正是盲人浏览器。
标准的禁忌是表格布局，主要是因为它不按相关性对网站内容进行排序。 对于阅读您网站的人来说，向下看两英寸而不是页面的最顶部是没有问题的，但屏幕阅读器读取的是代码，而不是视觉视图。
因此，您应该确保拥有重要的内容 - 高级标题（最好是
或）、主菜单（在列表）以及源顶部div中的内容，以及不那么重要的内容（徽标、横幅、快速菜单等）确实非常重要的是需要更进一步的可访问性。 您始终可以重新排序内容在 css 中实际显示的位置。A main concern when thinking SEO should always be usability.
