Unfortunately, even with lots of information circulating the Internet, business owners still make mistakes when it comes to conversion rate optimization. I’d like to help you avoid the three most common pitfalls:
1. Not adding positive emotional response
In your copywriting, include positive storytelling to help convey benefits. Help your reader envision himself benefiting from your product or services.
2. Not adopting a mobile-first strategy
More than half of consumers use their mobile devices to surf the Internet. If your landing page or site isn’t mobile-ready, you’ll turn off prospects.
3. Not caring about the site speed
Your pages need to load fast. Visitors expect a page to fully load in fewer than 2 seconds.
This is most crucial things to be noticed about in your site to work with optimal and get better results.
