I think there is a point where too much initial traffic can hurt the success of a blog. For example, if you have a daily blog and realistically aim for 50 views a day, than you must be able to provide keyword rich, relevant content to 50 people each consecutive day. I am sure this seems quite basic, however, there are plenty of bloggers who start out strong but are not able to maintain a consistent flow of traffic in to their blog, or even website.
I am just starting out in understanding
SEO and have the goal of 300 hits per month on my blog. I think wowtgp said it best: quality, key-word rich content and outsourcing. Guest blogging seems like a great way to (a. expand readership
and (b. keep fresh, new content on the blog.
