The folks at Wix have had some hiccups with Google over the years, which made their brand known as a not so SEO friendly platform. To combat that negative branding, Wix launched a contest where if you outrank them for the term [seo hero] in Google, they will give you $50,000.
Here are the terms:
We’re going to create a new Wix website optimized with the search term “SEO Hero”. You’re invited to create your own website (feel free to use any platform). If your site ranks the highest for that search term in 4 months’ time, we’ll give you $50,000. Yes, it’s that simple.
The details of those terms are in this FAQs and this legal document. You can't cheat and by cheat they mean, use tactics against Google's webmaster guidelines.
It is pretty funny seeing some of the responses from the SEO community.
