Or so it has been claimed. Has anyone subscribed to the ebook describing how to get free PPC advertising as seen here: http://www.articlesbase.com/FreeGoogle.php Would Google and others even let someone get away with expensive PPC advertising for no costs at all? Seems unlikely, but perhaps someone has an idea how he gets away with it.
Sell ad space on your landing pages. I can't believe people fall for this, as it's pure rubbish. If you can find an advertiser who is going to pay you to advertise on a ppc landing page...best of luck to you.
