Buy solos to a landing squeeze page where you offer something free in return for optin then forward to sales page to build your list. You need to add the tracking code to your websites code, but you don't have to turn on tracking to trying buy solos. Start small with 50 clicks from a few different sellers to see different results.

You will definitely want a squeeze/capture page. This will allow you to capture the name and email of the interested person for later marketing campaigns.

Depending on what your blog niche is, solo ads can be extremely effective. Most solo ad lists contain people looking for Biz Ops or Affiliate Marketing products.

If your selling actual physical products, or are outside of the biz op niche, Facebook ads might be your best bet!

Hope that helps!
