Search Engines: they come most from Google 60-80%, Bing, Yahoo and others is the rest. If your traffic site most from Search Engine, your site have some rank in search Engine , and when your rank increase, you can get more traffic from Search Engine. How to increase your site rank? You need to build the back link by post comment at blogs, forums, others site allow share post for backlink
I often use some site for get some good back link:
Xomba : The site with pagerank 4, when you register and create a new post , they will two type for posting: article and bookmark.
Article is normal article which you can add your link embed inside the content.
Bookmark is easily to make with 50 word relate to your links , the title is your title post or your blog name or your keyword your want to promote.
Xomba is allow to add Google Adsense , but with a limit traffic , you may not get much from them , the best thing is the back links you make is get high rank on Google with quick time.
Redgage : (page rank 4). you just sign up, and go to upload at right corner upload your link with title, tag, descripsion and your link. Redgage also provide a bonus , if you a lucky you can get some $ for fun.
Snipsly: (page rank 3) is a good place for back link also. You register at Snipsly and post a small article with your link inside content.
Referring Sites : This can come from social bookmarking , forum post, or blog comment post....
The volume from them may varies and can go up or down depend on people trend and also your interesting content. I often post at forum which allow the signature ( link to my sites); or blog to expand the network, post at dofollow forum , or dofollow blog is also a good idea to build back links and get referring traffic. You can read more about Dofollow at here:
The social bookmarking is waste your time , so I submit my link to Digg and StumbleUpon and let people vote by themself.
Another tips is add the social bookmarking button to your blog. People like your post will bookmark and may share to others , this will increase your traffic site fast.
Direct Traffic : This traffic from your loyal readers, they remember your site url and type direct or someone add your site is homepage. The people may increase your page rank , your Alexa rank and may also spread your site.
