Businesses with websites of 401-1,000 pages get 6 times more leads than those with 51-100 pages. The benefit of WordPress is that you don't need to be an HTML expert or experienced designer to add content. The platform is free and allows you to easily set up, manage, and update your site.

2. It's search engine-friendly

In the U.S., we conduct 12 billion searches per month on average. SEO leads have a 14.6% close rate, while outbound leads such as direct mail or print advertising have a 1.7% close rate. As Google Engineer Matt Cutts says, "WordPress automatically solves a ton of SEO issues."

If you want your website to have a polished look, you no longer need to pay a programmer thousands of dollars to create it. Use sites like ThemeForest and WooThemes to find themes as low as $10.
