Early web teaches us the reasoning behind today's search engines interworking:

When many bloggers or webmasters talk about certain topics they often annotate what they are saying with references and highly editorial links to relevant websites, often Wikipedia.  This is why they are such a highly regarded authority, and trusted in the search engines. The same is true for other websites which are highly trusted, but don’t necessarily command the amount of volume or clout of a major website. The search engines understood this, and that is why any contextual link is weighed very heavily in the algorithm when deciding what is relevant, and how popular.

It only makes sense. If bloggers talk about a movie they saw over the weekend, and mentioned a restaurant they went to afterwards, this is seen as a vote of confidence by the search engine spiders.

No one wants to link out to an unpopular source

As humans we follow the herd instinct. It’s nothing to be ashamed about, as it has kept us alive for millions of years. This is why it’s very difficult to become of those referenced sites unless you can first appear larger than what you truly are. Fake it to you make it can apply here, but more realistic is to network and provide something of great value, so they can’t ignore you, whether that’s information, product based, or shock and awe.

The links aren’t going to come on their own. To “build” these contextual backlinks is very possible, but you need to know where to place them. Much like this quality article website, BigWebDaily, there are numerous options to place your links inside relevant, quality content.

*Article Directories, Web 2.0s, Forum Discussions, Press Releases, and Guest Posting are the more popular methods to get in content links.*

Since you have full control over where you place your content, you can register to these public  sites, submit your content, and embed links to your webpages. Unlike most 3rd party websites that you will have no chance to submit content to, you are in the driver seat. The downside is many other webmasters or marketers know this and submit as well, making it hard to get noticed.

Article websites typically have stringent moderation so it’s suggested to start off with a free blog hosting platform where you can literally do whatever you want to it (within reason). Sites such as Blogger, Wordpress, and Tumblr are excellent options to create a free web presence online.

Once you get the hang of writing unique, quality content and embedding backlinks, register to a couple Article sites such as this one, ezinearticles, squidoo, hubpages, and a few others. There you will have a community and more moderation, but the benefits are often greater as readership and value of the links increase.

The internet is made up of people, and people love to communicate, collaborate, and share ideas and information. This is why Forums are a great medium to discuss what you are passionate about, and linking to relevant webpages when applicable. Fortunately many forums permit a signature where you can put links back to your site. The search engines will see all the discussions on a page, followed by your links, making them highly relevant and more powerful than a thin content filled forum profile.

True power online comes with syndication and networking. This is why Press Releases do very well to spread the word about your business or service, while spreading links to whoever picks up the newswire service. PRweb knows this, and that’s why they advertise themselves as not only a pr service, but a link building one as well; keep in mind there are plenty of free pr distributors, but the syndication is the most important part.

Guest Posting opens up Pandora ’s Box and can quickly overwhelm novice marketers. There are literally millions of websites that will accept guest posts, but quantity is not always the best policy. If you aren’t an expert in your field yet, it’s best to take Attila the Hun’s strategy of united the smaller chieftains; you can submit your guest posts to the sub level bloggers in order to gain the confidence and momentum needed to successfully post to the more prestigious bloggers, or gatekeepers of your niche.

Link building is not a new principle, but many forget the origins of its purpose. Links signify trust, quality and a vote of confidence. Don’t put all your eggs in one basket (method), and be sure to use the above to gain some effective long term contextual backlinks.
