I usually recommend that people install WordPress at the root directory of their sites. Even if you intend to mostly use WordPress for a blog, and run it at /blog/, you can still do that when WordPress is installed in the root directory.

Included in the header.php template of most WordPress themes, there is an important hook called wp_head. This essential hook enables WordPress functions to output content to the browser in the <head></head> area of your web pages1.
