I came across an interesting video by Matt Cutts head of Google’s webspam team. I was already aware that hyphens are better than using pipes for blog titles.
What’s a pipe? It is the character or key below the backspace on a standard keyboard. To use a pipe, just hold down your shift key and (|).
The problem with using pipes in the middle of a group of words when someone searches for those words in the exact phrase, the version with pipes will not show up in (SERP) Search Engine Results Page, but the version with hyphens will.
SERP: A search engine results page (SERP), is the listing of web pages returned by a search engine in response to a keyword query.

Here are two examples of a blog title using a pipe and hyphen.
