Would linking to your landing pages be bad for your organic rankings? This is the question posed on Cre8asite Forums, where a webmaster wonders the benefits of possibly linking to a completely different type of page (in terms of layout, etc.)
The answer: probably not. EGOL mentions that "they would probably be filtered from the search results." But if they are unique pages, that may not be the case.
Moderator iamlost says something else, though: why would you want to link to your landing pages? The point of having such pages is so that you can track your incoming traffic from PPC. If you interlink them on your web page, the metrics will be off. This is a thought that is echoed by forum administrator sanity.
Make your life easier by isolating your landing pages from the rest of your site. It's a way in from your ads only, not a way out (from your site).
