How to Tell If You’re Overbidding on Google Ads
How to Tell If You’re Overbidding on Google Ads (and How to Fix It)
Everyone thinks they want their business to show up at the very top of a Google search page. It feels great to type your specialty into your phone and see your practice listed before anyone else. But fighting for that number one spot is often a costly mistake.
If you are operating on a strict budget, aggressively bidding for the top position can choke your campaign and limit your new leads. In other words, you might be overbidding on Google Ads.
Overbidding happens when you pay a premium price for a few clicks instead of a reasonable price for many clicks. Fortunately, your Google Ads dashboard has specific metrics that tell you whether you are paying too much per click. Here is how to read that data and fix your bidding strategy.
The short answer: You are likely overbidding if your campaign loses a large share of impressions to budget (Search Lost IS (Budget) of 50% or more) while losing very few to rank (Search Lost IS (Rank) near zero). That combination means you win almost every auction you enter, but pay so much per click that your budget runs out early in the day.
Why Being Number One on Google Can Cost You Leads
Google Ads operates as an auction. To appear higher on the page, you generally have to pay more for each click. Your position is also shaped by your ad quality, which is why Quality Score matters so much.
Imagine your daily budget is $30. If you outbid every competitor to guarantee you are the very first result, you might pay $20 to $30 per click. Your budget will be gone after one or two people click your ad.
Now imagine you lower your bid. Your ad might show a little less often than some competitors’ ads, and it might appear lower on the page. But because you are no longer outbidding everyone, those clicks might cost only $5 each. Your $30 budget now buys you six visitors a day instead of one. (For context, RevKey typically sees clicks for therapists range from about $3 to $10, though costs vary by location.)
Six potential clients visiting your website gives you a much better chance of capturing a lead than one.
The Google Ads Metrics That Expose Overbidding
To find out whether you are overpaying, look at three impression share metrics in your Google Ads reporting. Together, they show how much of the available market you are capturing and why you are missing the rest. You can add them as columns in your Campaigns view; Google explains how in its guide to getting impression share data.
Search Impression Share
Search Impression Share is the percentage of times your ad actually appeared out of the total number of times it was eligible to appear. If 100 people searched for an anxiety therapist in your city and your ad appeared for 40 of them, your Search Impression Share is 40%.
Search Lost Impression Share (Budget)
This is the most important metric for diagnosing overbidding. It tells you what percentage of eligible searches you missed simply because your daily budget ran dry. If this number is 80%, your ads are missing 80% of possible impressions because you spent your money early in the day, leaving most local searchers to your competitors. If you see this number climb, it is also worth asking whether your Google Ads budget is too low to compete.
Search Lost Impression Share (Rank)
This metric shows the percentage of eligible searches you missed because your Ad Rank was too low, either because your bid was lower than competitors’ or your ad quality was weaker. These three numbers roughly add up to 100%, so reading them together tells you exactly where your missing traffic went.
How to Tell If Your Google Ads Campaign Is Overbidding
You can diagnose an overbidding problem by looking at how these three metrics interact. You are very likely overbidding if you see this pattern in your account:
Your Search Lost IS (Budget) is high, around 50% or more.
Your Search Lost IS (Rank) is very low, often under 10%.
Your Search Absolute Top Impression Share is high, meaning that when your ad does show, it is usually the very first ad on the page.
Your average cost per click is well above what is typical for your market.
For example, a campaign with 45% Search Impression Share, 50% lost to budget, and only 5% lost to rank is winning nearly every auction it enters. It is paying top dollar to be first, so its budget runs out quickly and it misses half of the searches it could have shown up for.
You are essentially buying one or two very expensive clicks and then closing up shop by lunchtime.
Note: If your campaign uses the Maximize Conversions bid strategy, Google advises against relying on the Lost IS (Budget) column, because it isn’t compatible with that strategy (source). In that case, watch your average cost per click, your absolute top impression share, and Google’s budget simulator instead.
How to Fix Overbidding in Google Ads
If your metrics show that you are overbidding and losing traffic to a depleted budget, you need to get Google’s algorithm to prioritize click volume over ad position. How you do that depends on your bid strategy.
If You Use Manual Bidding or Maximize Clicks
The fix is simple: lower your maximum cost-per-click (CPC) limit. Lowering this cap tells Google you refuse to pay premium prices for a single click. Your ads will drop slightly lower on the page, but your daily budget will stretch much farther.
If You Use Maximize Conversions
With an automated strategy like Maximize Conversions, the algorithm will often overbid on its own because it predicts a top-position click is likely to convert. To rein in the AI, set a Target cost per action (Target CPA). Google has been relabeling this setting as simply “Target CPA” in the bid strategy options.
By telling Google exactly how much you are willing to pay for a conversion, you push the system to look for cheaper clicks that still lead to inquiries. That naturally lowers your bids and extends your daily budget. Start with a target close to your current average cost per conversion, then adjust gradually, since a target set too low can throttle your traffic. If you are weighing your options, our guide to Smart Bidding strategies for therapists walks through each one.
Keep in mind that Target CPA is only as good as your conversion tracking. If Google is counting the wrong actions as conversions, it will optimize toward the wrong results. If you are getting clicks but no leads, fix your tracking before changing your bids.
Find the Sweet Spot Between Visibility and Cost
A profitable Google Ads campaign is about balancing visibility and cost. Accepting a slightly lower position on the page is often the smartest financial decision a practice owner can make. Overbidding is one of the common mistakes that make Google Ads campaigns fail, and it is one of the easiest to fix once you know what to look for.
Frequently Asked Questions About Overbidding on Google Ads
-
Usually not when your budget is limited. The top position costs more per click, so it can drain your daily budget before most potential clients ever search. More clicks at a lower position typically produce more leads.
-
There is no single target. What matters is why you are losing impressions. Losing impressions to budget while losing almost none to rank points to overbidding. Losing impressions mainly to rank points to bids that are too low or ads that need better quality.
-
Not if you are overbidding. Lowering bids moves your ad slightly down the page, but it lets your budget cover more searches throughout the day, which usually increases total clicks and inquiries.
-
Lost IS (Budget) is traffic you missed because your daily budget ran out. Lost IS (Rank) is traffic you missed because your Ad Rank wasn’t high enough to win the auction. They point to opposite fixes, so always read them together.
