Welcome to the Q&A Forum

My SERPs for a competitive term I felt I underperforming for dropped about 10 spots overnight after I added "noindex,follow" to the product pages. From the 3rd page to the 4th page, so it's not like I had a lot to lose. My SERPs for less competitive long tail keywords, which is where I'm getting most of my traffic, have dropped slightly or stayed the same. Should I cross my fingers and hope for a recovery? Revert the product pages back to "index, follow"? Any thoughts?
