You open Auction Insights, see a competitor sitting at 85% impression share, and your stomach drops. So you raise bids. That reflex — reacting to a number instead of reading it — is the quietest way founders burn budget on Google Ads. Auction Insights tells you what happened in the auction. It never tells you what to do about it.
What Auction Insights actually shows
The report compares you to other advertisers bidding in the same auctions you are. It works for Search, Shopping, and Performance Max campaigns. Open it from the campaign, ad group, or keyword tab — click Auction insights.
Six metrics matter:
| Metric | What it means |
|---|---|
| Impression share | Share of impressions you got vs. the ones you were eligible for |
| Overlap rate | How often a competitor showed at the same time as you |
| Position above rate | When you both showed, how often they ranked above you |
| Top of page rate | How often your ad landed at the top of results |
| Abs. top of page rate | How often you hit the very first slot |
| Outranking share | How often you outranked them (Search only) |
These numbers tell you your position in the fight. They tell you nothing about anyone's profit. That's the first trap to remember.
When to raise bids — when Rank is the problem
Auction Insights alone isn't enough. Read it next to two columns in your campaign table: "Search lost IS (rank)" and "Search lost IS (budget)."
- High lost IS (rank) means you're losing the auction on Ad Rank — not because you ran out of money. Fix it with a higher bid, a better Quality Score, or more extensions.
- High lost IS (budget) means you didn't lose at all. You just ran out of cash. Raise the budget, not the bid.
Founders miss this constantly. They see low impression share and raise bids on reflex — when the real problem is the budget drying up by 3pm. Raising bids there just empties the account faster.
When to leave bids alone — the number moved, the result didn't
A new competitor enters. Overlap rate jumps. Their position above rate climbs. It looks scary. But if your CPA and conversion volume are flat, leave it alone.
Auction Insights measures the competition. It doesn't measure your business. As long as your cost per conversion stays in target, more competitors showing up isn't your problem. It's theirs — they're paying more to fight for the same space.
The trap nobody talks about
A competitor at 85% impression share isn't automatically beating you.
They could be bidding on broad junk terms. They could be buying clicks that never convert. They could just have a bigger budget. You can't see their ROAS, their CPA, or whether they're profitable at all.
Chasing impression share means competing in a game where you can't see the scoreboard. The competitor "dominating" the auction might be losing money every single day. So why run after them?
The only numbers that tell the truth are your own CPA and conversions — the ones in your account, not the ones in a comparison report.
Quick reference
| Situation | What to do |
|---|---|
| Lost IS (rank) high, CPA still fine | Raise bid or improve Quality Score |
| Lost IS (budget) high | Raise the budget, not the bid |
| Overlap spikes, CPA flat | Do nothing |
| Competitor's position above rate high for 4-8 weeks | Check keywords + landing page before touching bids |
| Impression share drops during 11.11 / 12.12 | Normal seasonal swing — don't panic |
During big sale seasons — 11.11, 12.12, year-end — large brands pour budget into the same auctions. Your impression share dropping is expected. Bidding hard to fight them is the most expensive move you can make all year, and it usually loses to whoever has the deeper pockets.
What to do next
Before you touch a bid next time, open Auction Insights and ask one question: does this number actually move my CPA? If the answer's no, do nothing.
That's the same principle AdBlueprint runs on: focus on the numbers that move real money, and ignore the ones that just spike your heart rate. A comparison report is a diagnostic tool. It isn't a reason to react every time a competitor twitches.
