What are some recommended ways to get more links to my site?

Good content is always the key. Other sites will naturally want to link to other sites that have good content.

It's also good to post to relevant forums in your industry. Viral videos can be helpful too, as long as they are relevant.

Be sure to create and include meta tags on every page. The site must be well-organized. If your content is fresh and lucrative the number of traffic will positively increase.

Does viral video help in link building ?

You should update your site content regular by quality.

If you will update your site contents regular then search engines will give you good response and you can get good organic traffics through SEs.

you can do also traffic promotional works like forum posting, social bookmarking, social networking etc.
