Auction Insights is one of the most useful and most misread reports in Google Ads. It is the only place the platform tells you how you are doing against the specific advertisers you compete with, rather than in isolation.
The trouble is that its metrics sound similar and get confused constantly. Advertisers ask what a good outranking share is as if there were a fixed answer, treat overlap rate as a quality score, and ignore position above rate entirely. Used correctly, these four metrics form a clear competitive picture. Used carelessly, they mislead. None of these metrics shows who clicked, so if you suspect clicks rather than bids, use our plan to stop competitors clicking your ads.
This guide defines each metric in plain language, explains what counts as a good outranking share, and shows how to turn the report into decisions.
What Auction Insights Measures
Auction Insights compares your performance to other advertisers competing in the same auctions, over the keywords, campaigns, or ad groups you select. It does not show their budgets, bids, or actual rankings. It shows relative metrics: how you stack up against them across the auctions you both entered.
That distinction matters. None of these numbers describe your campaign in absolute terms. Every one of them is a comparison against a named competitor, which is exactly why a single target number is the wrong way to think about them.
Outranking Share, in Plain Language
Outranking share is the headline metric and the most misunderstood.
It is the percentage of total eligible auctions where one of two things happened: your ad ranked higher than the competitor's, or your ad showed and theirs did not appear at all. Both count as outranking, because in both cases you won that auction relative to them. The denominator is all the auctions you were both eligible for, not just the ones where you both appeared.
- It rewards both winning and showing up. Outranking the competitor when you both appear counts, and so does appearing when they are absent. Visibility is part of the metric, not separate from it.
- It is always relative to one competitor. Your outranking share against a weak rival and a dominant one will look completely different on the same keyword.
- It moves with rank and presence together. You can raise it by ranking higher, by appearing more often, or both.
This is why the question what is a good outranking share has no fixed answer. A 70% outranking share against a minor competitor may be unremarkable, while a 40% share against the category leader may be excellent.
What a Good Outranking Share Actually Looks Like
Stop looking for a magic number and start looking for a trend.
The useful way to read outranking share is comparative and directional. Pick the competitors who matter, the ones you most want to beat on your highest-value terms, and track your outranking share against them over time. Rising is good. Falling is a warning. The absolute value matters far less than the direction and the competitor it is measured against.
| Question | Wrong way to read it | Right way to read it |
|---|---|---|
| Is my outranking share good? | Compare to a fixed benchmark | Compare to your own trend against the same competitor |
| Which competitor matters? | Treat all rivals equally | Focus on rivals with high overlap on high-value terms |
| Why did it drop? | Assume the metric is broken | Check rank, presence, budget limits, and competitor activity |
| How do I improve it? | Just raise bids everywhere | Improve Quality Score, presence, and bids on terms that matter |
A falling outranking share on a key term against a key competitor is a genuine competitive signal worth acting on. A number in isolation is not.
Overlap Rate: Who You Actually Compete With
Overlap rate answers a different question: how often does this advertiser show up in the same auctions as me?
A high overlap rate means you and that advertiser frequently appear together, which identifies them as a real competitor for your traffic. A low overlap rate means you rarely collide, so their presence in the report is less relevant to your strategy. Overlap rate is your map of who your true auction rivals are, separate from how well you do against them.
Reading overlap rate first tells you which competitors deserve your attention. Then outranking share tells you how you are doing against those specific rivals.
Position Above Rate and Top-of-Page Rate
Two more metrics complete the picture, and they are about placement rather than presence.
Position above rate is how often a competitor's ad showed in a higher position than yours when you both appeared in the same auction. It identifies who consistently beats you on placement in head-to-head auctions, which is often more actionable than outranking share because it isolates the moments you both competed and lost position.
Top-of-page rate and absolute-top-of-page rate describe how often your ads appear at the top of the results and in the very first position. They are not competitive comparisons in the same way, but they tell you whether your visibility problem is about presence or about position, which changes how you respond.
Turning the Report Into Decisions
Reading the metrics is half the job. The point is what you change.
- Identify real rivals with overlap rate. Focus only on advertisers you actually compete with often.
- Track outranking share over time against those rivals. Watch direction on your highest-value terms, not a static target.
- Use position above rate to find lost head-to-head auctions. These are the clearest opportunities to improve rank.
- Diagnose the cause before raising bids. A drop can come from Quality Score, a budget limited by spend, or a competitor's new aggression, and each calls for a different fix.
- Check for wasted spend first. If invalid traffic or weak terms are draining budget, fixing that can improve presence and outranking share without adding budget.
That last point connects this report to budget efficiency. If your campaign is limited by budget because wasted clicks are consuming it, your outranking share suffers for a reason that has nothing to do with your bids. Cleaning up waste can restore presence and competitiveness at the same time; our guide on Google Ads limited by budget covers that link directly.
The Bottom Line
Auction Insights is competitive intelligence, not a scorecard. Overlap rate shows who you really compete with, outranking share shows how often you beat them across all eligible auctions, and position above rate shows who outranks you head to head. There is no universal good outranking share, because every figure is relative to one competitor. Track the trend on the terms and rivals that matter, diagnose drops before reacting, and remember that recovering wasted budget can lift your competitiveness as surely as raising a bid.
