I run a weekly newsletter riddle contest, if you’re the first one to answer it correctly you get a cash prize of 25 USD. Right now I use a landing page: enygmato.com and mailerlite for the newsletter, but I’m thinking of making the next step.
I thought about building a website where you can log in, have your profile, and get a weekly ranking. Also thinking SEO would be an important matter, in my mind SEO for apps is harder, but I have limited knowledge.
What do you recommend for the specs I want and the SEO concern?
Thanks in advance!
