Ranking high in the search engine results pages is a clear indication that your optimization efforts are working. The same goes for an uptick in traffic to your website. And if you see robust sales, then you can say without any reservation that your online business is on the right track to success.
However, not all webmasters with high SERP rankings and considerable traffic are enjoying substantial sales. Some may not even be selling anything off at all.
While great rankings and traffic are primary ingredients for a successful business online, having both is not a guarantee of one. If you have both, but sales are weak to non-existent, perhaps you might want to look at other possible reasons, like your web design practices.
Some people may not realize it, but web design plays a role in achieving conversions. SEO might get people to see and click the link to your website in the SERPs, but once they’re there, it’s your web design that will be crucial to getting visitors to stay and, hopefully, give you the conversions you need.
Conversely, a website’s design can also drive people away, especially when it doesn’t give visitors the best user experience.
