Welcome to the Q&A Forum

Great thoughts, thank you. I agree that companies really don't have SEO in mind when creating many tools. Some very useful tools are that way. There is a balance of options here - the benefit they see from using test and target (and they have seen great results improving userability on the site and refining their processes. It has created great efficiency that have led to improved site conversions), and the SEO factor. I guess what I'm looking for is a few things: 1. What are the effects of using hidden div tags and javascript redirects. 2. Possible ways to mitigate any negative effects in my rankings of those pages. From what I have read (and just the story of my SEO life) is that there really isn't much surety when it comes to this...no one seems to know exactly what will happen. I guess I'm looking for someone who has used hidden div tags or javascript redirects and how that has affected their ranking on those specific pages...as well as the site as a whole.
