link building

Link building is simple, its all a numbers game. Either you can use alot of low quality links or you can use alot of high quality ones. Most people choose to go with the later however both are useful.

Mix the two together and you will be ranking before you know it

For all intensive purposes its always best to test specific strategies. Every niche is unique and no one will be able to definitively tell you exactly how many links of what quality you will need etc. Test Test Test

There are tons of methods of backlinking and there is no one set method that will be here to stay permanently due to continuously changing search engine algorithms so you have to keep up with the updates.

Currently the latest and most successful method of backlinking is known as "tiered" backlinking. In which your main site (also known as your money site) is at the top of the tier, and is linked by 2-3 other tiers of web properties.

Tier 1- Your Main site

Tier 2 (These All point to your main site)- Web 2.0's with High Domain Authority , High Pr Manual Backlinks, Social Bookmarks

Tier 3 (These point to your Web 2.0's)- 1000's of low level blog comments, forum profiles, wikis, and social bookmarks

This varies of course but this is the basic structure

In case you don't know web 2.0's are sites which allow the user to add their own content and maintain it themselves as though there are their own websites.

These include sites like Tumblr, blogspot, blog.com, weebly, pinterest.

First of all you need to what is link building. Link building can increase the number of high-quality links pointing to a website, in turn increasing the likelihood of the website ranking highly in search engine results. Link building is also a proven marketing tactic for increasing brand awareness.
There are different types of link building.
Editorial link
Resource link
Acquired link
Reciprocal link
Forum signature linking
Blog comments
Blog comments
Social bookmarking

There are many ways of creating backlinks to your website:

Comments in blogs. These won't give you SEO value, but they may direct some traffic to your site if your ideas are good enough and you can add value to a blog post.

On Directories. Beeds a previous research to know if a particular directory is actually providing value to a site or not.

Signatures and posts in forums. Find forums where signatures can include follow links preferably. Make sure your signature is not spammy and the keywords used as anchor text are natural (use your brand or an URL). Posts won't give you SEO value, but, as blog comments, they can direct traffic if they are relevant, informative and add value to them.

Help webmaster to find broken links and suggest your site as a replacement. Of course, you have to find broken links where your content is pertinent. Using Wayback Machine may be useful to check the content of that disappeared page.

Automatic link building. There's a big debate about its benefits but there're many companies using it. It can help you find quality "follow" links that otherwise wouldn't be accessible for you. Risks of penalties are minimal if your backlink profile is balanced.

Social networks: Quora, Reddit, Twitter, Google + (pages and groups), Facebook (pages and groups)... there are many places you can deliver a relevant and useful link that somebody else may use later on their sites.
