Know when to hold ’em, know when to fold ’em. I’m talking marketing plans. Most online sellers have many campaigns going at once. From a new email campaign to your latest store makeover and logo design, to all your side projects, knowing when to quit a marketing project can cause anxious moments for entrepreneurs. Coca-Cola hasn’t changed its basic logo since 1887, so some campaigns can run a long time. However, many are time sensitive. Using some sort of metrics program can help in some instances, along with feedback from customers and your own gut feelings. Hold or fold? Take stock.
