Definition
The Auction Insights Report in Google Ads shows how your ads compare to other advertisers competing in the same auctions. You can access it from the Keywords, Ad Groups, or Campaigns sections to see which domains compete with you, how often they appear, and where they rank. It's the primary competitive intelligence tool inside Google Ads.
How to Read the Five Auction Insights Metrics
Auction Insights reports five key metrics.
[table]
Column | What It Measures | What It Tells You
Impression Share | Percentage of impressions each advertiser received out of eligible impressions | Who has the biggest share of the auction. Your baseline of competitive presence
Overlap Rate | How often another advertiser's ad received an impression in the same auction as yours | Which competitors you actually compete against, not just who's in the market
Position Above Rate | How often the other advertiser's ad showed in a higher position than yours when both showed | Which competitors are winning ranking against you
Top of Page Rate | How often each advertiser's ads appeared at the top of the page | Who is dominating premium ad positions
Outranking Share | Percentage of auctions where your ad ranked above the other advertiser's ad, or where their ad didn't show at all | Where you're already winning against a specific competitor
[/table]
Understanding these five columns together gives you a full competitive picture. Each column answers a specific tactical question, and together they show you whether or not a competitor is a real threat.
How B2B SaaS Should Read the Report
The report answers three questions that matter for pipeline growth.
1. Who is the real threat?
Look at Overlap Rate combined with Position Above Rate. A competitor with 60%+ overlap and 40%+ position above rate is actively winning traffic that should be yours. That's a real threat. Prioritize competitor conquest against them.
2. Who is showing up but not beating you?
A competitor with high overlap but low position above rate is showing in the same auctions but losing. You're already outranking them. No urgent action is required for now, so just monitor.
3. Who should you ignore?
A competitor with low overlap and low position above rate is either targeting different keywords or losing on ad quality. They're not affecting your pipeline. Ignore them and focus your attention elsewhere.
Most B2B SaaS accounts waste time and money on the wrong competitors. Auction Insights tells you who to bid against.
How This Feeds Competitor Conquest
Auction Insights is the diagnostic tool that shapes your competitor conquesting strategy. Our full playbook on bidding on competitor keywords walks through the strategy, but the decision of which competitors to target starts here.
The workflow:
Step 1: Pull Auction Insights at the campaign or ad group level for your core non-brand campaigns.
Step 2: Identify the top three to five competitors by overlap rate.
Step 3: Cross-check position above rate. Anyone with 30%+ position above rate is beating you in enough auctions to matter.
Step 4: Prioritize competitor conquest campaigns against those specific competitors, with dedicated ad copy and landing pages.
Step 5: Re-check Auction Insights monthly because competitive landscapes shift more often than you think. A competitor that was dominant six months ago might be pulling back today.
Without this diagnostic step, you’re going blind on competitor conquest. With it, every dollar goes toward beating the specific advertisers actually costing you pipeline.
What Auction Insights Won't Tell You
Auction Insights has limitations.
- It only shows advertisers who are direct competitors in the same auctions. If a competitor targets completely different keywords, they won't appear.
- It shows aggregated data, not per-auction detail. You can't see which specific searches you lost.
- It doesn't show ad copy or landing pages. To get that visibility, you need external tools.
Our guides on PPC competitor research tools and the best PPC spy tools explain how you can use external tools in addition to Auction Insights to get a complete picture.
The Rule for B2B SaaS
- Review Auction Insights monthly.
- Identify the top three competitors by overlap and position above rate.
- Build competitor conquest campaigns against those specific advertisers.
- Ignore competitors with low overlap, even if they seem important in the market.
The Auction Insights Report tells you where the pipeline is actually being contested and where it's being lost.
