Question:Answer by William Gets:
If my landing pages have a slightly different layout and content depending on the source (organic&direct traffic), does it affect my search results.
Answer by William Gets:
The problem would come with duplicating content and that your direct traffic landing pages (from your PPC campaign for example) should be “no-indexed” to avoid duplication penalisation from Google.
So, SEO the heck out of your organic landing pages and follow all the rules for the direct source landing pages – which is not to be taken lightly; a landing page can make or break your campaign. A/B testing advised.
