Each page of your website contains elements that contribute to it's overall success. They must complement each other in achieving your goal --- a call to action on the part of visitors. Home page is the main portal, and therefore deserves extra attention.
Here are some bad ideas—things NOT to do when designing a website. You can annoy visitors to the point of driving traffic away forever. Large files slow down pageloads. Pop-up windows create more work and confusion for visitors. Splash or “entry pages” serve little purpose on most sites.
No pop-up windows
Don’t annoy visitors with automatic pop-up windows. It is fine to allow new windows to open when links or text or images are moused over or clicked on, but let the viewer control that decision. And provide a “close” button if the window does not disappear by itself.
