A blog is not a blog without content so once you’ve set your blog up you need to focus your attention upon creating useful content. What you choose to create will depend a little on the topic that you choose to write about (on that note, most successful bloggers have some focus to their blogging whether that be a niche or a demographic that they write for).
Post your article links on social media and blog directories. Get traffic to your site with frequent updates on Twitter, Facebook, and other social media sites. Find blogging communities that match your readership and post links to relevant articles on their comments or forums. This helps in getting traffic to your site as well as raising your search engine rankings.
Oh yeah, I also do all of the above for articles that I write for other blogs. So, if I'm guest posting on a blog, I tend to share it even more than I do my own content. If you guest post on a person's website, you should do the same – the more you share it, the more traffic that person will then get, and the more likely they are to re-share it too.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
