Auction Insights: See Who You Really Compete With on Google

Most advertisers guess who they compete with in Google Ads. They name the big brand in town, or the agency down the road, and plan around that guess. Google already tells you who is actually appearing alongside your ads, in a report many accounts never open: Auction Insights.

It will not show competitors' budgets or keywords. It shows something more useful for day-to-day decisions: how often you and each rival appear for the same searches, and who tends to show above whom.

Where to find it

Open a Search campaign, an ad group or a set of keywords and look for Auction insights in the menu. Choose a date range of at least a month, so a single busy week does not distort the picture. The report lists the domains whose ads appeared in the same auctions as yours, with your own row at the top for comparison.

The numbers worth reading

• Impression share: the share of eligible searches where your ad, or theirs, actually appeared.
• Overlap rate: how often a competitor's ad showed at the same time as yours.
• Position above rate: when you both showed, how often their ad sat above yours.
• Top of page rate: how often an ad appeared above the organic results.
• Outranking share: how often you ranked above a competitor, or showed when they did not.

Read them together. A rival with high overlap and a high position above rate is the one taking the clicks you most want. A rival with low overlap barely competes with you, however big their brand is.

What the report helps you decide

If your impression share is low, check why before raising bids. Google reports separately whether you lost impressions to budget or to rank. Lost to budget means the campaign ran out of money. Lost to rank usually means ad quality, relevance or bids, and raising the budget will not fix it.

If one competitor appears above you almost every time, look at their ads in a live search. Their offer, their reviews or their call extension may explain more than their bid does. Matching their bid without matching their offer often just makes clicks more expensive for both of you.

A new name suddenly appearing with high overlap is worth noting. It may be a new business, an aggregator, or a company bidding on your brand name. If it is your brand name, a small brand campaign usually protects those searches cheaply.

What it does not tell you

Auction insights covers only the auctions you entered. Searches your ads never qualified for are invisible here, so a rival that dominates keywords you do not target will not appear. It also says nothing about whether their clicks turn into customers. A competitor who outranks you every day may be losing money doing it.

Treat the report as a map of where you meet competitors, not as a scoreboard to win at any cost.

A monthly habit

Once a month, export the report for your main campaigns and note three things: your impression share, the top three rivals by overlap, and any new names. Over a few months you will see seasonal patterns, such as competitors who spend heavily before festivals and disappear afterwards, and you can plan your budget around them instead of reacting.

FAQ

Can I see a competitor's bids or budget?

No. Auction insights shows how often ads appeared and in what order, never what anyone paid.

Why does my own domain appear with less than full impression share?

Budget limits, ad rank and targeting settings all stop your ad showing on some eligible searches. The lost impression share columns show which cause applies.

Does it work for Performance Max?

Coverage is more limited than for Search campaigns and can vary, so use Search campaigns as your main source for competitive comparisons.
