When it comes to pay-per-click advertising campaigns, keywords are an important tool, but symbols can also draw the eye to the ad. A few months ago, PPC Hero ran a blog post explaining how to put registered or trademarked company names in PPC ads to help increase click-through rates and set you apart from competitors in the SERPs.
The PPC Hero post got David Szetela thinking: Could other symbols in ads get advertisers noticed? Szetela tells us about a few experiments such as inserting bullet points, and greater and lesser signs. Google's policy does prohibit advertisers from including symbols in ad text, but these seem to work, he said.
