You may be working hard at SEO and paid search listings to draw visitors to your site, but if your site search function falls apart when they get there, they'll waste no time in shopping elsewhere. One of our own surveys found that 73% of visitors will leave an e-commerce site within one to two minutes when they don't find the products they're looking for - and 36% would never bother returning to that site. As we move into the holidays, and the biggest shopping season of the year, you don't want three-quarters of your shoppers leaving your site in 60 seconds because they can't find the gifts they want.
