Try to use pyramid link model. Think quality over quantity.

Pyramid LInk model is great and sadly you dont have any new link building strategy by the end of 2014. See that you concentrate on social media sites, update fresh content in these sites and see that you are post on them on a regular basis. Dont be shy to participate in discussions on social media sites, this is something that can increase and promote trust flows to your website.

It's important to combine different techniques, not to use just one...and focus on quality.

first off all share your unique and fresh content on your website , than you can share social bookmarking , directory submission , info graphic submission , blog submission and many other activity you can use for your website.

I can only recommend what I have used myself, so here're my suggestions:
key link-building tactics nowadays include: Creating, publishing and promoting high quality content that links back to your site, getting recommendations from trusted sites and individuals.
Being active on social media and generating a high level of social proof. Syndicating your content on major industry websites. Becoming a featured columnist or a guest blogger on popular industry blogs or websites.

Hi,

This is a very broad questions and you have many options available. Your correct question should be what is the most effective. I did an "EXPERT" posy where I asked "14" top bloggers this questions. When I added up all the answers, the following were the top:

1) Writing high quality content

When you write HIGH quality content not only does Google love it but many people automatically want to link back to it. These people linking back will have authority blogs with traffic which can be awesome to build a brand for yourself. Focus on writing the best content by putting a twist when you write. Whatever topic you choose, research your competition and look for things they are missing and add it to your content.

2) Guest Posting

Has always been awesome because it can build traffic and get you solid links quick. The key is to find relevant guest posting opportunities within your niche. In return, many authors will allow 1-2 links within the author box. You get brand recognition and traffic which can translate to a link from the guest posting blog or traffic when they visit your website.

I hope my competitors are following the advice in this thread!

Build authority pages which can go viral. From these pages link to your money site somewhere from the page. Then share these authority pages on major social sites.
