1. Design your website in CSS. CSS stands for Cascading Style Sheets, which are written instructions for how the site is presented to your visitors. CSS allows you to update the text and appearance of your entire site with little effort.
2. Keep your site design simple. Do not have music or videos loading when someone visits your home page. Keep your site clean and easy to navigate.
3. Use meta tags. Google mainly uses meta tags, such as your Title, Description and Keywords to correctly index your site and put it in the right category.
4. Avoid using giant files that take forever to load. Optimize your images before uploading them to your website.
5. Check your links often. The Google bots won't know what to do if they find a broken link or can't find their way off of your home page. Their only option is to leave, and you want your entire site indexed, not just your landing page. Use text links and avoid JavaScript when creating your navigation, and provide the search spiders with a Site Map.
