When a competitor starts appearing above you in Google Search, it is tempting to panic, raise your bids, and copy their ads. Auction Insights can help you respond more calmly. It does not show you a competitor’s budget, bids, or private account data. It shows how often you and other advertisers appeared in the same auctions, and how often each advertiser won a visible position. Used well, it turns a vague feeling — “competition is getting tougher” — into a specific question you can investigate.
This guide explains what each Auction Insights column means in plain language, where to find the report, and how to use it without falling into the trap of copying competitors. The examples below are illustrative only. They are not predictions or guarantees for your account.
What Auction Insights Actually Shows
Every time someone searches, Google runs an auction. If your ad is eligible for that search, you enter that auction. Auction Insights compares your performance with other advertisers who entered the same auctions during the same period. It is a relative view, not a complete market report. If a competitor did not enter the same auctions, they may not appear. If your campaign was paused, limited by budget, or targeted to a different location, that also changes what you see.
Think of it like a local high street. You can see which shops are open when you are open, and which shopfronts people notice first. You cannot see their rent, their profit, or what customers do after they walk inside. Auction Insights is useful for the same reason: it tells you about visibility in shared auctions, not about whether a competitor is actually profitable.
Where to Find the Report
In Google Ads, open a Search campaign, ad group, or keyword view, then look for Auction Insights in the reporting options. You can view it at campaign, ad group, or keyword level. Start at campaign level for the big picture, then narrow down to ad groups or keywords only when you have a clear question. For example, if one campaign’s impression share fell, check its main ad groups. If one ad group changed sharply, check its top keywords.
Choose a sensible date range. A single day is usually too noisy, especially for a small account. Two to four weeks gives you enough auctions to spot a pattern without hiding a recent change. Also compare like with like: the same campaign, the same device split if relevant, and the same location targeting. A change in your own targeting can look like a competitor change if you are not careful.
The Columns, Explained Simply
Impression share
Impression share is the percentage of eligible auctions in which your ad received an impression. If your impression share is 62 percent, your ad showed in about 62 out of every 100 auctions where it could have shown. A low number does not always mean a problem. It may mean your budget ran out, your bids were low, or your ads were not eligible for some searches.
Overlap rate
Overlap rate shows how often another advertiser’s ad received an impression in the same auction as yours. An overlap rate of 45 percent means that, in the auctions where you appeared, that competitor also appeared 45 percent of the time. High overlap means you are genuinely competing for the same searches. Low overlap may mean you serve different parts of the market, even if you sell similar products.
Position above rate
Position above rate shows how often the other advertiser’s ad appeared in a higher position than yours when you both appeared. This is often the number people worry about most. It is helpful, but it does not mean your ad is bad. A competitor may appear above you because of a stronger ad, a higher bid, better relevance, or a different landing page experience. You need other evidence before you decide what to change.
Top of page rate and absolute top of page rate
Top of page rate shows how often an ad appeared above the organic results. Absolute top of page rate shows how often it appeared in the very first ad position above those results. These rates help you understand visibility, but the top position is not always the best value. Sometimes the second or third position brings enquiries at a lower cost per click, and that can be a better result for a small budget.
Outranking share
Outranking share combines two ideas: how often your ad ranked higher than a competitor’s ad, and how often the competitor’s ad did not show at all. It is a useful summary, but do not treat it as a score to win at all costs. Outranking a competitor on searches that never convert is not a victory. It is just spend.
A Worked Example, With Honest Numbers
Imagine a small plumbing business running a Search campaign in one city. Over four weeks, the campaign has an impression share of 58 percent. One national competitor has an overlap rate of 52 percent and a position above rate of 61 percent. That means the competitor often appears in the same auctions and often appears higher.
The tempting response is to raise all bids by 30 percent. The calmer response is to ask three questions. First, are we competing for the same searches, or is the competitor winning on broad, low-intent terms such as “plumbing jobs” or “plumbing courses”? Second, are our ads and landing pages as specific as theirs for the searches that matter, such as “emergency plumber near me”? Third, is our budget running out early in the day, so we miss the evening searches when people actually need help?
Suppose the business checks its search terms and finds that the competitor overlap is strongest on general advice searches, while its own conversions come mainly from urgent, local searches. In that example, the smarter move is not to chase the competitor everywhere. It is to tighten keywords, add negative keywords for job and training searches, and protect budget for high-intent local terms. These are examples only, and your numbers will differ, but the decision process is the point: use Auction Insights to ask better questions, not to justify a bigger bid on everything.
What to Do When a New Competitor Appears
A new name in Auction Insights does not automatically mean you must change your strategy. New advertisers often test aggressively at first, then settle down. Before you react, check whether your clicks, cost per click, and conversions actually changed. If your cost per click rose slightly but your cost per enquiry stayed steady, you may not need a major change.
If your impression share fell and your budget is limited, check whether you lost impression share because of budget or because of rank. Google Ads separates lost impression share by budget and by rank in other reports. That distinction matters. Lost share due to budget usually calls for a budget or targeting decision. Lost share due to rank may point to bids, ad relevance, or landing page experience. For background on relevance, read the Quality Score guide, and for bid choices, read the bidding strategies guide.
Why Copying Competitors Usually Backfires
Copying a competitor’s headline or offer feels fast, but it removes the reason someone should choose you. If three ads all promise the same thing in the same words, the customer has no reason to pick yours except price. You may also copy a weakness: a competitor might be bidding on the wrong keywords, sending traffic to a weak page, or advertising an offer they cannot fulfil well.
Instead, use Auction Insights to find gaps. If a competitor dominates broad terms but is weak on a specific service, location, or time of day, that gap may be your opportunity. If a competitor always appears above you on a keyword that rarely converts, let them pay for that visibility. Spend your budget where you have proof of enquiries, calls, or sales, not where a report makes you feel second.
Your Weekly Auction Insights Checklist
- Check Auction Insights at campaign level for the last two to four weeks, not just yesterday.
- Note any new competitor names and any large change in overlap or position above rate.
- Compare the change with your own clicks, cost per click, and conversions before reacting.
- Check lost impression share by budget and by rank, so you fix the right problem.
- Review search terms for the ad groups with the biggest change, and add negative keywords where needed.
- Improve one specific thing at a time: ad relevance, landing page clarity, or keyword focus.
- Re-check after two weeks. One week of data is often just noise for a small account.
- Write down what you changed and why, so you can judge the result fairly next time.
Using the Free Tools Before You Raise Bids
Before you increase bids to chase a position, run the numbers. Use the Budget Calculator to see how a higher cost per click would affect clicks and monthly spend. Use the ROAS and Profit Calculator to check whether a higher position could still be profitable after product, delivery, and ad costs. Use the Keyword Planner and Tracker to organise the keywords where competition changed, and to note which ones actually bring enquiries.
For example, if your average cost per click rises from $2.00 to $2.60 in an illustration, a $300 monthly budget would buy fewer clicks. That may be fine if conversion rate improves, but it is a poor trade if it only buys a higher position on low-intent searches. Again, these are illustrative figures, not forecasts. Your market, location, and offer will produce different results.
Conclusion
Auction Insights is a visibility report, not a verdict on your business. It can show you who shares your auctions, how often they appear above you, and where your visibility changed. It cannot show you whether a competitor is profitable, well run, or worth copying. The best advertisers use it to focus their attention: they check the biggest changes, compare them with conversions, fix relevance and keyword targeting first, and only then consider bids or budget.
Start small this week. Open one campaign, note the top two competitors by overlap, and check whether their strength matches the searches that actually bring you customers. If it does not, you have just saved yourself a bidding war you did not need to fight. If it does, you now have a focused list of ads, keywords, and landing pages to improve — and a clear way to measure whether the improvement worked.
