Ads are available for DIY projects; like bands, zine distros, labels, non-profits, etc. No corporate stuff or other bullshit.
DoDIY.org has been around since 2007. In the year of 2016 alone, the site had 119,459 unique visitors (that's an average of 9,955 per month)!
There are two ways to sponsor on DoDIY and they're both cheap.
1. If you're a band or performer, you can pay $2/month or $20/year to have a link to your music available under your hometown. See the "California" page (under "Oakland") for an example.
2. You can place a 100px square graphic ad, viewable on the bottom of 8 pages of the site, including the home page and this page. That'd cost $10/month or $100/year.
Just send me an email at alyssa [at] dodiy [dot] org and let me know your info, I'll walk you through it.
