There are many things you can and should do to make your site as good as possible. Here is a list of some of those things.
Include ALT tags with each image. This is important for search engine rankings and to ensure that those visitors who search without graphics can understand your site.
Include the proper Metatags on each page of your site. This helps improve your rankings on some search engines.
Be sure that your navigation makes sense. Help your visitors get around on your site by making it easy for them to find things.
Keep your visitors coming back by including “What’s New” sections on your home page and in a special section.
