As we dig deeper into everything that may affect keyword ranking, be it positively or negatively, we continuously run into the question; “Do inventory levels, specifically running low on inventory, negatively impact rankings?”

So that meant digging into as many listings as possible and ferreting out the information we needed.
Nonetheless, I came up with some data that we may find useful.
