@minzinger asked if I'd help create a forum topic on free self-promotion for your Tapastic comic series, using Project Wonderful. I've started doing this for my own series, Oops, for the past month now and it's helped boost my views and reader interactions.
So I am here to help!
Project Wonderful is a great online advertising site that connects people that want their ad banners seen on relevant sites, with people with sites that want to sell space for those banner ads. However, Project Wonderful does something even better by letting people offer free ad space for us indy creators to bid for free.
Also, on a side note, if you have your own webcomic site, you can eventually place ad boxes on your own site for people on Project Wonderful to bid on with actual cash. I've also done this with my own OopsComicAdventure.com website, and it makes enough for me to bid for more prime ad spaces for my Tapastic banner ads.
Below is my 9 step process for advertising for free and hopefully drawing in more viewers to your comic and Tapastic as a whole.
So here we go, with my screenshots:
