I have a friend who made a website a few years ago. He has been building very safe links to it, like yahoo directory, citysearch, yellowpages. although these type of links sound lame, the site is actually doing surprisingly ok in the serps. Now he wants to do better in the serps and he asked me to do very white hat, safe seo. what are some safe links that I can give him? and please, let's not start arguing about the definition of "white hat" and "safe". yeah I know there is no such thing as "white hat seo" unless you wait around and hope other people link to you. yeah I know nothing is 100% safe. I am just looking for things that "usually, most of the time" dont get a site penalized.
