Google Ads impression share in Bangalore: the two loss reasons that need opposite fixes

If your Google Ads impressions are lower than they should be, the account is telling you why in two columns: Search Lost IS (budget) and Search Lost IS (rank). One means your ads are winning auctions but running out of daily spend. The other means you are entering enough auctions but losing them. Bangalore accounts often read both numbers and apply the same fix to each, which is the mistake that wastes money fastest.

What is Google Ads impression share?

Impression share is the percentage of eligible auctions your ad showed in, out of every auction it was eligible to enter. Google Ads Help's guide to impression share data defines the two loss reasons separately: Search Lost IS (budget) is "the percentage of time that your ads weren't shown on the Search Network due to insufficient budget," and Search Lost IS (rank) is the percentage lost to a poor Ad Rank in the auction. Both numbers live on the campaign tab, and Google adds a caveat worth knowing: lost IS (rank) will not show correctly on the ad group tab if your budget already ran out during the period you are checking, because a campaign that stops spending early never gets to compete on rank for the rest of the day.

Why do these two numbers need different fixes?

Because they describe different failures. A campaign losing impression share to budget is winning its auctions and then pausing itself once the daily cap is spent, often by early afternoon for a Bangalore business running ads through the evening dinner or clinic-hours rush. Raising the budget, or narrowing targeting so the same budget covers fewer, better auctions, fixes that.

A campaign losing impression share to rank is doing the opposite: it has budget left over but is not winning the auctions it enters. Google Ads Help's page on Ad Rank describes it as depending on your bid, the quality of your ad and landing page, the Ad Rank thresholds for the auction, and how competitive that specific auction is. Raising the budget here changes nothing, because the account was never spend-constrained. The fix is a higher bid, a better quality score on the keyword, or a landing page that matches the ad's promise more closely.

What happens if you apply the wrong fix?

A Bangalore account losing 40% of impression share to rank, then given a bigger budget instead of a quality or bid fix, will spend the extra money entering the same losing auctions at the same low position. The spend goes up, the impression share barely moves, and the account looks like it needs even more budget next month. This is the pattern behind Google Ads campaigns in Bangalore that struggle to spend the full budget even after two or three rounds of increases: the constraint was never money.

How do I check which one is happening to my account?

Open the Campaigns tab in Google Ads, add the columns Search Impr. share, Search Lost IS (budget), and Search Lost IS (rank), and read them together for each campaign rather than at the account level, since one campaign can be budget-starved while another sits on plenty of unspent budget and a weak Ad Rank. A campaign showing 30% lost to budget and 5% lost to rank has a spending problem. One showing the reverse has a competitiveness problem. Some campaigns show meaningful numbers in both columns at once, which usually means the keyword set is too broad for the budget it has, so tightening targeting fixes both at the same time.

Does automated bidding change this?

Partly. Under Target CPA, Target ROAS, or Maximize Conversions, Google adjusts your effective bid per auction based on predicted conversion likelihood rather than a fixed number you set. A campaign on automated bidding can still show lost impression share to rank, but the reason is no longer simply "the bid is too low." It can mean the algorithm decided a particular auction was not worth bidding aggressively for, given the target you set. If lost IS (rank) climbs after switching to automated bidding, check whether the target itself (a Target CPA set too low, a Target ROAS set too high) is the real constraint before touching anything else in the account.

What is a healthy impression share for a small Bangalore business?

There is no single number that fits every category. A competitive term like a dermatology clinic or a marketing agency in a crowded area typically runs in the 60 to 80% range even for a well-run account, because so many advertisers are bidding on the same searches. A narrow, low-competition, or branded term should sit above 90%. Anything below 50% on a term you consider important is worth a look this week, not next quarter, and below 20% usually means the account is missing most of the auctions it should be winning.

Frequently asked questions

**Does a higher budget always improve impression share?**

No. It only helps if Search Lost IS (budget) is the larger of the two numbers. If rank is the bigger loss, more budget just funds more losing auctions at the same position.

**Can a campaign lose impression share to both budget and rank at once?**

Yes, and it usually points to a keyword list too broad for the daily budget. Narrowing the ad group often reduces both losses together rather than needing two separate fixes.

**Where do I find these columns in Google Ads?**

On the Campaigns tab, under Columns, add Search Impr. share, Search Lost IS (budget), and Search Lost IS (rank). They are not visible by default.

**Why does lost IS (rank) sometimes show as zero even with a weak Ad Rank?**

If the budget ran out earlier in the day, Google Ads Help notes the ad group tab will not report accurate lost IS (rank) figures for that period, because the campaign stopped competing before rank could be measured for the rest of the day.
