What Is The Best Title Tag Format

In this experiment I will be using four different title tags.

1. Use a generic title that is often used by websites not optimizing their site
2. Use an optimized title tag that reads naturally to readers
3. Use an optimized title tag specifically for search engines
4. Use a title tag and a meta-title tag

The websites are located here:
