The perception that people have of your business is a reflection of your website. If you have an impressive website, people are more likely to think highly of your business, and they are more likely to purchase.
Think about it. If you go to a website that has spelling errors, pages that don’t render correctly, and little useful information, are you more or less likely to buy? Even more, do you suspect that search engines might penalize the site?
Putting time and work into your website to make it read well is one of the best things you can do to improve conversions and rank better on search.
