I use Imprezzio Marketing for my tough cases where I can't get the client to move up in Google or if there are deeper issues that I can't fix. I'm fortunate to have these guys as my "in case of emergency, break glass" option.
I like their monthly reports- which provide a summary of what's been done and what they're going to do next month.
They don't take shortcuts or employ risky blackhat tactics. Thanks to Joy and the folks at Imprezzio Marketing!
