I have noticed a few oddities recently with the titles of web pages in SERPs. However, it seems there are several main conventions: Contact Page - Joe Schmoe's Awesome Site // - Hyphen Contact Page — Joe Schmoe's Awesome Site // — Em dash Contact Page | Joe Schmoe's Awesome Site // | Vertical bar Contact Page « Joe Schmoe's Awesome Site // « Left double angle quotes Is there any reason to use one over the other?
