I've started the SEO category while ago and just written one article about it - learn SEO basics which turned out great and looks like people are really interested to get to know SEO, so i'll be starting kind of weekly SEO trick/tricks set of articles.
This week we will learn how to increase your inbound links number without paying for any campaigns. For the ones who don't know Inbound links are links form high rated web sites/domains that link to yours. And in case someone doesn't know what does SEO stand for, it's Search Engine Optimization 
So, what you need to do is very simple thing, if you are a blogger - have a blog like me, you probably have bunch of friends with their own blogs sharing similar subjects, find their top rated articles (most often they are most commented ones) by searching on Google for Sitelinks (view image above) and ask them to put one paragraph for example at the end of those articles.
That paragraph should be descriptive and shouldn't have more than 3 links. Here are two good examples, guest post info at the beginning on "Stylize your digg count" and blockquote paragraph on it's demo page about Stylized Web. Ok, what do you get now with these links?
- Increase your traffic significantly.
- Improve your visibility in the search engines.
- Provide an added resource to your website.
- Save you a lot of advertising money.
- Save you time.
Sounds good, does it? The name for this is "link building", and with few more like this and some sense for business you could start a SEO company
