Welcome to the Q&A Forum

We don't use any eCommerce platform with fully developed in-house. Was more about whether it was good to no-index the search results, which you have answered. I will go about putting this in the robots.txt

Very good video, thanks. I think i just need to change my ads around alittle for better CTR.

I wouldn't use rel=next/prev AND canonical to "View All". The canonical will almost definitely overwhelm the weaker rel=next and you'll be showing all search visitors the view all page. There's not a lot of data on rel=next/prev yet, but my testing with clients is going positively. If you aren't currently facing problems, I think I'd give it time to do its job. Pagination is a tough problem, and Google is not consistent about their preferred methods (some of their reps have gotten in pretty heated arguments on opposite sides). It's more than a little annoying, given how common of a problem it is. The only down side to rel=next/prev is that it's new and Bing currently doesn't support it.
