Google Ads determines ad position using Ad Rank — calculated from six factors: your bid, ad and landing page quality, Ad Rank thresholds, auction competitiveness, search context, and expected impact from ad assets. Higher quality ads typically win better positions and pay less per click. Quality Score is a diagnostic tool, not a direct auction input.
Every time someone searches on Google, an ad auction runs in milliseconds. The winner is not simply the highest bidder — Ad Rank combines bid with quality signals and context to determine both who appears and in what position. The claims below come from Google Ads Help, Google's official support documentation for advertisers.
Google Ads Ad Rank is determined by six factors: bid, ad and landing page quality, Ad Rank thresholds, auction competitiveness, search context (location, device, time, search terms), and expected impact from ad assets.

Ad Rank is the set of values that determines whether your ad is eligible to show and where it appears. Google states it is calculated from six factors: your bid, ad and landing page quality, Ad Rank thresholds, auction competitiveness, search context (location, device, time), and expected impact from ad assets.
No. Google states: "Generally speaking, the advertiser with the highest Ad Rank gets to show in the top position." Ad Rank includes quality measures, not just bid — a lower-bid advertiser with higher quality can outrank a higher bidder.
Yes. Google explicitly states: "Higher quality ads can often lead to lower CPCs. That means you pay less per click when your ads are higher quality."
Quality Score is built from three elements: expected CTR (likelihood the ad will be clicked when shown), ad relevance (how closely the ad matches the intent behind the search), and landing page experience (how relevant and useful the landing page is).
No. Google's documentation explicitly states Quality Score is "a diagnostic tool" — it is not used as an auction input. The actual auction uses separate quality measures calculated in real time.
