I love it when I run into another pay per click agency because then most bloggers can hop on board offering more ad space on their sidebar as way to increase revenue earned on their website. Of course another great thing about pay per click advertising campaigns is that they could turn out to be a great opportunity to advertise.
BizzClick is not only a pay per click agency but they also have their own loyalty program and their own community where you can interact. BizzClick has everything that a blogger or firm would want to look into when advertising or monetizing their website. I say check them out and let me know what you think.
With all agencies you work with you will want to ensure that they have a professional 24/7 support team, personal managers for each client, and a great variety of tools for creation of advertising campaign.
