Sorry this may be a ridiculous question, but hopefully someone will be able to help me out: we would like to have a different landing page for traffic coming from our adwords campaigns, than for traffic coming from our natural listings. what would be the best way to ensure that all the Google pagerank goes to the natural traffic website url, and not the landing pages used for our Adwords campaigns. Can we use nofollows to stop Google indexing the paid traffic landing pages, without affecting our quality score? Thanks very much in advance for your answers!
You should be able to prevent indexing of your PPC-only page with an entry in your robots.txt file. Using nofollow tags will not affect quality score calculations.
