7. No Need To Fully Redesign Your Site
It used to be commonplace to need to redesign your website every few years. I used to recommend a website redesign every 3 to 5 years, but that is no longer the case. If you use WordPress, coupled with a well-vetted and regularly updated theme, you will be able to continuously update your website, so it grows with you for years and years to come.
The opposite is true for DIY platforms. At some point, your business will outgrow capabilities of that platform and you will have to rebuild it on WordPress. Save the money now and built it on WordPress from the get-go!
