Thanks for taking the time to answer. Agreed. It's confusing at best. It confused the heck out of me when I was deconstructing the behaviour.
We generally get indexed faster than 2-3 days. Last time I checked the average time to index was around 40 minutes. Guess that's because the engines know our content changes frequently.
_1- If the products on your site are selling within minutes, then why are you focusing your attention on how Google will index them? _Most of our purchasing customers come via Natural Search.
2- As the products sell out within minutes and after so the redirection is stopped, then why would that affect how Google ranks your site? I should have been clearer: t****he queue will trigger after a threshold is reached, not when product is sold out. But if it's a particularly high demand product, it could sell out before threshold dips below that configured for the queue.
Good suggestion about opening queue in a tab.I will explore that option.
