How long should someone stay on your website?
They say "Users often leave web pages in 10–20 seconds, but pages with a clear value proposition can hold people's attention for much longer. To gain several minutes of user attention, you must clearly communicate your value proposition within 10 seconds."
What makes a website attractive to visitors?
So it's important to be visually appealing, polished and professional. Allow white space, uncluttered layouts with quality photographs and graphics look and let your message shine through. (See examples.) Equally important, the site must work quickly, correctly and as expected.
