Just a quick update on the Google update of its landing page quality score that is causing headaches for advertisers.
Two recent threads at WebMasterWorld Forums discuss the topic of landing page quality mostly without getting into all the numbers and frustration involved, and focus specifically on ways to help improve the quality of the landing page used in search engine marketing ads. Learn more at the threads, titled Quality Score for Advertisers - Good for Publisher? and Figuring Our Landing Page Quality.
In addition, a thread at Digital Point Forums titled Google Responds To My Request For a Landing Page Review offers a specific example of a site that was deemed to be of lower quality, primarily due to the number of websites offering similar type of content.
One more addition to this post: A very long thread titled Open letter to Google Regarding Changes to The Ad Words Program at WebMasterWorld Forums also gives some insight between many frustrated posts.
Join the above threads to get some good suggestions on improving your quality score in Google AdWords.
