I've seen several landing pages that consist of almost all images, no text. How can you have a good quality score with just images?
Simon Lueng, former google senior ppc analyst, says by having a professional looking web page with professional looking graphics you can increase your score. And he said, a strong privacy policy, about me, and even a terms or disclaimer page will help too. Side thought: Linking to authority sites like google increases your page rank so maybe it’s worth something in quality score. I don’t really know. But don’t forget content you can’t see like, alt img tags, table id tags, and div tags. All these have helped me when I was short on content. I stuff a few keywords in those all the time. For what it's worth... Simon Lueng did say something that struck me odd… google doesn’t consider duplicate pages with different headlines as duplicate content as long as it’s on the same IP.
Guys: On this landing page Quality Score, I think I may just have found a way to 'beat' it. I have made 2 landing pages in the past 2 days, and so far they're going real good in Google/Yahoo/MSN. Google is even giving 95% of my keywords (hundreds of them) a Great quality score, and min. bids of $0.05. And I spent probably a few short hours on each landing pages only! (100% White-hat on page optimization) So far, 3rd day, and my ads are still showing. So this might be a good sign! PM me if you might be interested. I'm not selling anything here, don't worry.
