Let's say I created 100 various landing pages for a particular niche, what is the best way to quickly obtain the quality score of each unique page/url?

I dont know a sure fire way of checking that many pages, but here is what I do.

When comparing a couple of pages I set one up and note its position, then move on to the next one and do the same. If the second page appears in a lower position, it's probably caused by it's quality score (assuming its the same keyword)

I don't know that there is a quick way. I think you just have to wait and see how things pan out.

you can get your quality score on the adwords campaign - look for it its there

I think there is a programm called movar ... this progarmm figures out such a thing. you can insert a couple different variables (text snippets) then tell the prog to randomly mix it. the prog then rembers which is the best by tracking peoples behaviours. After a couple weeks you have a very nice converting page.

theres a product developed for this called google googles.

This is what you do.

Go to the Google Keyword Tool. Click on the "Website Content" tab.

Now insert your 1st page into the tool. The keywords it returns you are the terms G would give you a good QS score on. If your target keyword isn't listed, massage until it is.

Repeat over ALL your pages.
