Not only did PosterBurner get good results from the sponsorship, but they also get to write an article about the results and bring in still more sales and PR.

It sounds like an all-around benefit to me.

I'd be interested in sponsoring DuckDuckGo, but I'd want to make sure I got referrer information.

Does anyone know if this is because DDG is using a redirect in between the link on their site and the advertiser's site, or is it just down to lack of set up on PosterBurner's end?

The ability to track and analyze is critical for a $1000/week spend.

"DuckDuckGo does not include referrer information in their links. This means that when you click on a link at DuckDuckGo, the site you are going to does not know where you come from."

Assuming they're refering to an ad, and not a search result, why not just link to http://www.mysite.com/?ref=ddg ?

$1000 for $1300 in sales seems high, is 75% ad spend normal for the industry ?

You do see duckduckgo.com in the referer, just not the search term. Although, if the person searches via the https version of the website, you wont see the referer unless you're using https your self.

And of course there is always the concept of a landing page, which other people have mentioned.

It's easy to track clicks for a campaign like this.

We spent $1000 dollars to get $1300

So reddit advertising was free or am I missing something?
