Here are Six Effective Web Design Success Tips for YOU to Keep in Mind when Designing a Search Engine and User Friendly Website:
1. Website Colors
Dark colors are generally a bad idea to use on a website as they appear gloomy. Try using light colors with a few strong colors to support it.
2. Load Speed
Keep your pages load time as fast as possible - people don't want to wait a whole minute just to load each page.
3. Site Navigation
Navigation. Keep your navigation accessible to your user where they can instantly have access to your site's content.
4. Consistency Throughout
Keep your layout and presentation consistent through your whole website. Always keep your navigation links at the same place otherwise it may confuse your visitors.
5. Website Width
Keep your website's layout at a fixed width of 780 pixels or use percentages for your site spanning. Everyone has different resolutions and people don't like having to scroll in all directions to view your website.
6. No Flash
Flash animations are nice, but make it difficult for people who don't have flash support and is harder for SE Spiders to crawl your site.
Hope these help!
