Google Ads Auction Insights: How to Read and Act on It
The Auction Insights report shows who you're competing against in the Google Ads auction. What each of the six metrics means and how to actually act on them.
Most advertisers glance at Auction Insights, see a list of competitor domains, and close it. That's a waste. Read correctly, it's the clearest picture Google gives you of who you're actually fighting in the auction and whether you're winning or losing ground, and every metric points to a specific action.
Here's how to read the report and, more importantly, what to do about each number.
What Auction Insights actually shows (and doesn't)
The Auction Insights report compares your performance to other advertisers who entered the same auctions you did. It does not expose their budgets, their keywords, their bids, or their spend. Anyone selling you "competitor budget data from Auction Insights" is selling a fiction.
What it does show is six comparative metrics for each competing domain. You can run it at the account, campaign, ad group, or individual keyword level, the keyword level is where the real insight lives, because auction dynamics differ wildly between your brand terms and your prospecting terms.
The six metrics, and what each one tells you
1. Impression share. The percentage of impressions you received out of the impressions you were eligible for. Low impression share isn't automatically bad, but the reason it's low is what matters (see "lost to rank" vs "lost to budget" below).
2. Overlap rate. How often another advertiser's ad showed at the same time as yours. A high overlap rate means you're consistently in the same auctions as that competitor, they're a direct rival, not an occasional one.
3. Position above rate. When you and a competitor were both shown, how often their ad ranked above yours. This is the head-to-head scoreboard. A competitor with a high position-above rate is beating you on Ad Rank (bid x Quality Score x expected impact), not necessarily on budget.
4. Top of page rate. How often your ad appeared above the organic results. Premium real estate, and a Quality Score lever, since better quality earns top-of-page placement at a lower bid.
5. Absolute top of page rate. How often your ad was the very first ad. Critical for brand terms, where being anything but #1 invites the click to a competitor.
6. Outranking share. How often your ad ranked above a competitor's or showed when theirs didn't. The single best summary metric for "am I winning this matchup." Rising outranking share = you're gaining ground; falling = you're losing it.
The number most people miss: impression share lost to rank vs budget
Add the two "impression share lost" columns to your campaign view (they live in the columns menu, not the Auction Insights report itself, but they're the report's natural companion):
- Lost to rank means you were eligible but your Ad Rank wasn't high enough to show. This is fixable without spending a dollar more, improve Quality Score (ad relevance, landing page experience, expected CTR) or raise the bid on terms that deserve it.
- Lost to budget means you ran out of money before the auctions ended. This is a budget or efficiency decision, not a quality problem.
Confusing these two is the most common Auction Insights mistake we see in audits. Teams pour budget into a campaign losing share to rank, when the actual fix was a better landing page.
How to act on what you find
| What the report shows | What to do |
|---|---|
| A competitor's overlap + position-above rate climbing | They're escalating. Shore up Quality Score and revisit bids on the contested terms before your share erodes. |
| High impression share lost to rank | Fix relevance and landing pages first; raise bids only on terms that convert. |
| High impression share lost to budget on profitable terms | Reallocate budget from weaker campaigns; this is recoverable volume. |
| Low absolute-top rate on your own brand term | Run or strengthen brand defense, a competitor is sitting above you on your own name. |
| A new domain appearing with rising overlap | A new entrant. Watch their position-above trend for two to four weeks before reacting. |
The trap: reading a snapshot instead of a trend
A single Auction Insights pull tells you almost nothing. The value is in the movement. Segment the report by month (or week, in fast-moving auctions) and watch whether each rival's outranking share against you is rising or falling. A competitor you've "always" seen in the report is background noise; a competitor whose numbers are climbing is a threat with a timeline.
Auction Insights is a diagnostic, not a strategy. It tells you where you're losing the auction; closing the gap is a Quality Score, bid, budget, and landing-page job.

Frequently asked questions
- What is the Auction Insights report in Google Ads?
- Auction Insights is a Google Ads report that shows how your ads compare to other advertisers bidding in the same auctions. It does not show your competitors' budgets, keywords, or actual bids. It shows six comparative metrics, including impression share, overlap rate, and outranking share, for the domains competing alongside you. You can run it at the account, campaign, ad group, or keyword level, and segment it by time, device, or other dimensions.
- How do I find Auction Insights in Google Ads?
- In the Google Ads interface, go to the Campaigns, Ad groups, or Keywords view, select the rows you want to analyze (or select all), and click the Auction insights button or tab. You need enough impression volume in the selected period for Google to show data; very low-volume keywords often return no report.
- What is a good impression share in Google Ads?
- It depends on the campaign's job. For a brand-defense campaign, you want impression share above 85-90%, leaving your own brand term uncontested is expensive. For broad non-brand prospecting, 100% impression share usually means you're overpaying; somewhere in the 40-70% range while hitting your cost-per-acquisition target is often healthier. The more useful number is 'impression share lost to rank,' which signals a Quality Score or bid problem you can fix, versus 'lost to budget,' which signals you're capped.
- Can Auction Insights show my competitors' keywords or budgets?
- No. Auction Insights only shows comparative auction metrics for domains you share auctions with. It never reveals their keywords, budgets, bids, or spend. To research competitors' actual ad copy, use the Google Ads Transparency Center; to estimate their keywords, use a third-party tool like Ahrefs or Semrush. Auction Insights tells you who you're up against and how often, not what they're doing.
- How often should I check Auction Insights?
- Monthly for most accounts, weekly during a competitive shift (a new entrant, a price war, a seasonal peak). Watch the trend, not a single snapshot: a competitor whose overlap rate and position-above rate are both climbing is increasing pressure on your terms, which is your cue to revisit bids, Quality Score, and ad copy before your impression share erodes.
