Winter Snow Effect on the Website
Winter Snow isn't exactly new, but it still works great to boost sales on small business websites during the Winter, and that is really what most of my clients are after. Sites where I added snow effects in 2017 had an average of 10-20% increase in sales, and customers often complimented the businesses for getting into the spirit of the season.
Try adding winter snow to your website this next Winter and see the effects it has on bounce rate, time spent per page, number of pages visited, the conversion rate, and social media sharing. In my experience it helps visitors form a positive impression of the business, and makes them significantly more likely to do business with the company.
