Every page on your website is important, but nothing tops the importance of your website home page. If your site were an actual brick-and-mortar shop, the website home page would be its reception area. It is where customers first gather, and what they see there will become a huge factor in their decision to stay on the site, or leave it.
What should your website home page have to make visitors decide to stick around? All things considered, what it all boils down to is how comfortable they would be about staying and exploring the entire website. Therefore, it goes without saying, that you need to do everything you can to give them that level of comfort, or they will leave.
