Wix.com has put up a challenge to outrank them for the keyword "SEO Hero" by March 16th 2017.
You can read the terms of the challenge below, and enter the competition here: http://www.wix.com/wix-lp/seo-heroes
You should pay attention to this part of the FAQ, before you all rush in:
What SEO guidelines should I use?
Follow Google’s guidelines for SEO (here’s the link). This is part of the challenge rules and you will need to follow these to keep your site in the running.
Not only does this mean no link building, but it basically gives Wix unlimited vague grounds for disqualifying you from the competition. And I won't even go into the possibilities of using this as a huge honeypot.
Good luck beating the competition with that 'great content' Yawn.
