Ad Rank is the value Google calculates in every auction to decide whether your ad appears, in which position, and how much you pay per click. It isn't just your bid: ad quality counts too.
We regularly see smaller businesses hold top positions against much bigger competitors, and it's almost never because they outbid them. It's because their ad and landing page match the search more closely. A local business with a page about exactly the service in exactly that area often beats a national brand sending everyone to its homepage.

Google recalculates Ad Rank every time an ad could show. According to Google, it's based on:
Because quality is part of Ad Rank, a business with a very relevant ad and landing page can appear above a competitor who bids more. Imagine two aircon servicing companies in Penang bidding on "aircon servicing penang":
| Max bid | Ad quality | Result | |
|---|---|---|---|
| Company A | RM4 | Generic ad, homepage | Position 2 |
| Company B | RM3 | Ad mentions Penang aircon servicing, dedicated page | Position 1 |
This is a simplified illustration (Google doesn't publish the exact formula), but it reflects how quality lets smaller advertisers compete.
You usually don't pay your full bid. Your actual cost per click is roughly the minimum needed to hold your position above the advertiser below you. So better quality can mean both a higher position and a lower price.
No, Google doesn't show it. You can see its effects in your impression share, "Search lost IS (rank)" and top-of-page rates.
