For good quality scores, your landing page must be targeted to your keyword. The Google robots that crawl the landing page determine this. What do they look for?
- a domain with all pages relevant to the main topic
- keywords in the domain name
- keywords in the page name / url of the page
- keywords in the title of the page
- keywords in the keywords meta tag
- keywords in the description meta tag
- keywords in the "h1" heading tags on the page
- a keyword density of 2-5%
Robots also like content. They don't like html, css, javascript or other code. Robots can't tell html from content in most cases, so lots of the html just dilutes the keyword density. I've had people run their pages through the tools at google.com/webmasters/sitemap, and google tells them the only keywords that google sees ranking highly are html codes!
What is the bottom line? A good sales page often makes a bad landing page for Adwords quality. It's sort of a double edged sword. A good sales page and lots of html, images, javascript, flash scripts, eye catching layouts and colors. A good landing page for adwords has nothing other than content targeted to a single keyword. In other words, a very boring page to look at.
How you find a middle ground between these extremes? Personally I like to use frames or iframes. I use these techniques to insert one page inside of another. So, my outer page is the high quality landing page, while the inner page is the sales page. The robots see the outer page when evaluating the landing page. The customers see the inner sales page when they link to it.
Here is an example of a landing page using frames...
<html>
<head>
<title>KEYWORD</title>
<meta name="description" content="A sentence or two about KEYWORD."></meta>
<meta name="keywords" content="KEYWORD"></meta>
</head>
<frameset rows="100%">
<frame src="INNER PAGE URL"/>
<noframes>
<body>
<h1>KEYWORD</h1>
KEYWORD RELATED CONTENT GOES HERE
</body>
</noframes>
</frameset>
</html>
The robots will read the "no frames" part of the page. Customers using modern browsers will only see the Inner Page in the frame. This way you give both sides what they want.
I recommend the following instead of direct linking to a clickbank sales page.
- Obtain hosting (free or paid) and domain name related to your topic
- Create a landing page using the frame technique described. I would optimize it for a single keyword as recommend in my free Adwords guide.
- point you Adwords ads to the new landing page.
You should see a boost to your quality scores by doing so.
