的 本系列的第一部分 提供了一些用于优化SEO页面上方面的有用技术的概述。但事实是，就帮助通过搜索引擎提高排名和知名度而言，非现场元素更为重要
谷歌’的算法主要是根据其他网站到您网站的链接（尤其是来自‘key’ or authority sites. So whilst all links are useful to an extent, getting a popular and trusted industry expert or a major organisation in your geographic area to link to your site is invaluable. You can use all the on-page techniques (metadata, content) in the world, but the 键 is getting authoritative sites to link to you in order to ensure your site is ranked highly in search results
People tweeting links to your content and sharing your website on facebook or linkedin, also generates valuable links (and potentially network effects) which will all contribute to enhancing your page ranking as well. This will also help in terms of branding generally, and is often a successful channel for ensuring your content is visible to relevant user communities and your 键 target markets.
为类似的博客和论坛贡献价值Writing blog comments and forum posts are a great way to promote your content as well, but make sure you are not just commenting for the sake of getting your link displayed. Writing guest posts for other blogs can also be a good way to promote your own website, as well as to build collaborative relationships with other content publishers. You can also share your content through sharing sites like Slide Share and 谷歌 Docs to increase its visibility.
Be careful not to go too far with off-site techniques however. Make sure it is 'natural' and relevant - you don't want sites to link to you if there is not a logical reason for it. 谷歌's algorithms will also analyse unnatural link profiles and anchor text and it may negatively affect your ranking if 谷歌 believes your site is artifically or unethically optimised.
