I know that its important to pack your pages with content but i still believe its crucial that your website looks good! There are so many things to look out for, so i've included just few tips to keep in mind when designing your site.
Learn which colours and fonts work best and use them throughout your webiste. A useful online application designed to help you select the appropriate colour scheme for your website is Adobe Kuler . It shows you thousands of pre-made colour schemes to choose from.
Don't forget your computer may have hundreds of fonts installed but thats no reason to use them all! The fewer the better. I suggest maybe two fonts - then make some rules on how they should be used and stick to them on every page! One should be a body copy font and the other used for headings.
When putting together your website, remember that images bring pages to life online just as they do in print.
Your website design should help people find what they want. Not to complicated.
Consistent page design and a familar look on each page, will help people navigate through your site.
Make your website look professional by eliminating typos and bad grammer!
