The best way to improve the SEO of your blog is by link building. Link building is not a new concept by any means but the more you know about it the better your blog will rank. It is said that links pointing to your website is the best way to have your blog climb the search engine charts and I agree. If you want to see results the first thing that you have remember is the greatest inbound links generally come from websites with a higher Page Rank then your own or just a high page rank in general. I would consider a high page rank to be a PR 3 or better. The next thing to remember is that the good links come from sites that have a lot of the same type of content as your own. For example if you have a wedding blog then we want links from wedding websites and other wedding blogs. The last thing all good links have in common is they link to your site with relevant keywords to your site. Again using the wedding blog for example you would want to use keywords link "wedding blog" or "bridal blog". If you follow these simple rules you will see results!
