Comment on Cloak Affiliate Links Tutorial by SEO Dave.

Link Cloaking PHP Script Like the AdSense ads, and Chitika ads, Clickbank uses javascript to serve it’s ads, so they are already ‘hidden’ from search engines.

If an ads built using javascript in a way that there isn’t a URL shown in the code (view source) you can be reasonably confident Google and other search engines can’t see the links as text links (no SEO value is passed).

If you can see the links in the javascript there’s a possibility search engines can read a link from the code. The Clickbank ads network uses javascript search engines can’t decipher into text links.
