Here's 1 free traffic method that I like: Guest Blogging.
Some bloggers solicit guest articles, in which case you can create a blog post and submit it for consideration. However, even those that don't advertise accepting guest articles may be open to the idea if you give them a reason why they should.
For example, you can:
- Trade articles with the blogger (so that they get to post an article on your blog too).
- Use the blog owner's affiliates links in your article, so that they make money when their readers buy a product.
- Offer something else attractive in trade, such as an endorsement in your newsletter.
