You still need traffic. With WordPress, you can drive a tremendous amount of traffic in a short amount of time. Google owns WordPress if that tells you anything. It means search engines can easily find your information and rank you higher.
By adding just one post a week to your blog, the search engines will love your fresh content and constantly come back to rank your site.
If you are doing any type of Social Networking (twitter, linkedin, facebook), you can have your blog posts automatically tied to your Social Networking sites.
Easily add audio and video to your blog without any 3rd party software. For audio, you can record audio using Sound Forge Audacity (a free program). For video, take the video with your digital camera and upload it to YouTube.com. You then add the embed code (conveniently given to you on YouTube.com) and VIOLA! You have full multimedia capabilities. In fact, you can use other people’s videos in your blog for quick and easy content.
Building a website is time consuming. Get this blog up and going within a few hours.
