Anyone else having problems with this now or is it just me? I have just had 4 sites that were making ok money, all have original content - not just a sales page - keywords targeted to the page, separate campaigns for each keyword all the good stuff etc etc. Recently these sites all went from QS 7/8 to QS1 with the reason of poor landing page quality. They are a mixture of styles, HTML, Wordpress etc. i cant find a common thread except that they all promote clickbank products (2 hoplinks per page all cloaked before anyone asks). I've also noticed there seems to be a lot fewer adwords ads promoting CB products than before. anyone?
Like most everyone else, you misunderstand Google's definition of a quality landing page. What they mean is that the page does not conform to one or more of their policies. Nothing to do with the way it looks, the HTML, style, what was used to create it or anything else. Read the Adwords guidelines and policies. You say they all promote CB products. That is likely the reason. Not that you are promoting CB products (although some may go against their policies) but that you are doing it the wrong way. Look in the policies for bridge page. Most affiliate marketers using Adwords have run into the same thing. Most never read or followed the policies or were banned for repeating the same mistakes. That's why you see less AMs using Adwords. That's good news for their competitors.
We were direct linking. Most ClickBank products share a particular style of landing page. As of a few months ago, Google isn't a fan of that style. We love less competition, but in this case we have quit promoting ClickBank products completely. It's not worth the LPQ Score risk. Too many low ones and bye-bye account. You might do OK if you design your own "normal looking, complete website" as a landing page, and are really subtle about how you steer people to the product. Seems like your sites weren't subtle enough.
