Analyze the competition - and make your site better.
If you were to buy tickets to local show, online, who would you do it through? What about the current process irks you - what do you loathe? Find the opportunity to fix it. Make your website as fluid as possible, and provide the most accurate, up-to-date information for users. Minimize processing fees and technology fees to a point where your clients aren’t feeling ripped off and you’re still hitting the profit margins.
Your ultimate goal? You want to be better than “the best.” Most likely, nobody sells online tickets the best way...yet. That’s where a creative and ambitious mind can take advantage and reap the rewards.
