If you run a seasonal business like summer holidays or skiing tours, then the biggest mistake you can do about your website’s development is starting it too late.
Let’s say you own and manage a small apartment building near the seaside. You need a new website for this small business. The summer season starts in June and ends in September. 99% of your guests are visiting your place during these 4 months. You may say: “oh, we have plenty of time until June”. Sorry to say that, but I think you’re wrong now. You are probably already late.
