A good example of a basic but highly functional website would probably be Majestecsocal.com. However, the exact type of design you should be considering depends on your target audience and niche. In some niches (like the one the example website is based around), users would want to have everything in one place, and hence a basic but very functional design would hit the spot pretty well.
Web analytics is the measurement of the behavior of visitors to a website. In a commercial context, it especially refers to the measurement of which aspects of the website work towards the business objectives of Internet marketing initiatives; for example, which landing pages encourage people to make a purchase. Notable vendors of web analytics software and services include Google Analytics, IBM Digital Analytics (formerly Coremetrics) and Adobe Omniture.
