Why can the biggest bidder end up second?
Because the bid is one input among six. Google's auction is built so that a relevant ad with a useful landing page can beat a higher bid on a weak one, and Google says that higher-quality ads can often lead to lower costs per click. The context matters too: the same keyword can rank differently on a phone at 9 pm than on a desktop at 10 am, because the searcher's location, device, time and exact words change what Google expects of the ad.
The result is that position is earned partly in the ad and the page, where a small business can outdo a larger one, and partly in the bid, where it often cannot.
How did a Mackay mortgage broker win the top spot on a lower bid? (example figures)
Three advertisers bid on "mortgage broker mackay". Google does not publish the sum it uses, so the figures below are an illustration of how the factors trade off, not a calculation.
| Maximum bid | Ad relevance | Landing page experience | Result | Average CPC paid | |
|---|---|---|---|---|---|
| Local broker | $12 | Above average | Above average | Top position, sitelinks shown | $8.40 |
| National comparison site | $18 | Average | Below average | Second position | $14.10 |
| Second local broker | $9 | Below average | Average | Below threshold, not shown | None |
The local broker's ad says "Mackay mortgage broker, 30+ lenders, home visits", and the page it opens shows the broker's face, the suburbs covered and a booking calendar. The comparison site sends every click to a national form. The broker pays $8.40 for clicks the comparison site pays $14.10 for, sits above it, and gets the room for sitelinks underneath. At the comparison site's price, the broker's 150 clicks a month would cost about $855 more.
What does Ad Rank decide besides position?
The price and the extras. What you pay for a click is the least needed to clear the thresholds and stay above the advertiser below you, so it is often less than your maximum bid. Ad Rank also decides which assets show: Google Ads Help ("About assets") says higher positions get the first chance to show sitelinks, callouts and the rest, and that assets need a minimum Ad Rank of their own. A bigger ad takes more of the page, which earns more clicks for the same position.
Can you see your Ad Rank anywhere?
No. Google never shows it as a number. You see its effects in four places in Google Ads: the Quality Score columns on the Keywords page, which show the three quality parts; Search top IS and Search abs. top IS, the share of times your ad sat at the top of the page and in the very first slot; Search lost IS (rank), the share of searches you missed because Ad Rank was too low; and Auction insights, which shows which competitors appeared with you and how often they ranked above you.
Where does Ad Rank show up in CoraVision?
CoraVision never sees an Ad Rank figure, because Google never publishes one. What it reads every night is the outcome of each day's auctions: the clicks, impressions and spend for every campaign. The causes sit in the Quality Score columns and Auction insights, which Cora reads off your screen in a session you start. Gage, the Google Ads specialist, teaches the Google Ads lessons in CoraVersity, which holds over 1,200 lessons across 13 platforms.
Questions
Is Ad Rank the same as Quality Score?
No. Quality Score is a 1 to 10 rating per keyword that Google shows you as a diagnosis, based on past performance. Ad Rank is worked out fresh in every auction, from your bid and live quality signals among other things, and Google never shows it as a number.
Can I pay enough to always be first?
You can bid high enough to be first more often, but the bid is only one factor, and an ad with a poor landing page can be outranked by a cheaper one with a good page. Google also says there is a minimum quality an ad must reach to show at all, whatever the bid.
