Newbies, we need to understant this. If we want to get fast traffic we need to be in the first page of a PR4+ website. You can do this with articles. For example, if you write an article and post it to EzineArticles then you will be in the first page for a day. You will get traffic because you will be in its first page.
You will get SEO traffic for article if you use long tail keywords with low competition. Fast traffic is equal to article directories. Long term is equal to SEO traffic.
If you need more fast traffic get a hot niche at clickbank. Get products with high gravity. A good niche is weight loss.
