Here's an oh-by-the-way.
One of our manufacturer's came out with a product via slow roll literally within the last 5 days. They have not announced the release of it to the retailers. I happened to stumble on it visiting their site while updating products.
I did a search of the term and found I wasn't the only one unaware of it so I scrambled to add the product to the site, promote it and submit it to the index late Tuesday.
It's Thursday and its showing in SERPs.
Would it have appeared that quickly if I didn't submit it via fetch? I don't know for sure but I'm inclined to think not. Call me superstitious.
Someone debunk the myth if you can. One less thing for me to do.
