I'm a travel blogger and have been making money online (still do) for about three years. Numbers vary but it can be anything between 800-2000 USD/ month. Most of this money has come from selling links in guest posts (sponsored posts) that I have published in my main blog and one or two additional ones I've had in the past. I only do this part time and have some other online projects too. During the past 3 years I've been gathering email contacts from links sellers and online marketing firms from around the world I've been doing business with, all of them high paying (around 70-250 USD/link/year) and the list now has around 3,000 contacts. I still (of course ) do business this way as it is rather effective to make some cash every month. My questions is: would bloggers in any niche be interested in getting hold of (in other words buying) this list to make money themselves with their blog/blogs/blog network? I would sell it for an affordable rate and can show proof that it does work ( I've actually helped-and still do- other bloggers make money using this same method)? I'd like to hear your thoughts.
