If you do nothing else for your website this month, write an article!
Original content is gold on the internet. In fact, copying articles and text from other sources will not help your website or increase your ranking. Google credits content only to the original website.
When you do take the time to write original content for your website, make sure you use it and link to it as much as you can. Use the articles you write in multiple places like blogs & tweets, then publish it in your newsletters or include them in a press kit. You can also submit your articles to ezineArticles.com. This article distribution website allows users to download and use your articles on their websites, ezines, etc. You can include a small about us/bio and link to your website. When other people publish your content, you not only get your name out there, you get valuable inbound links.
