What is Impression Share?
Impression Share (IS)
Definition, formula, India benchmarks, and the operator-grade nuance behind it.
Impression Share is the percentage of available impressions an ad won out of all impressions it was eligible for. It is calculated as impressions received divided by total eligible impressions. IS surfaces budget and Ad-Rank gaps.
Impression Share = % of eligible impressions captured.
Lost IS to budget = increase budget; lost IS to rank = improve QS or bid.
Brand-keyword IS should be 90%+ — otherwise competitors are stealing clicks.
Impression Share equals impressions received divided by total eligible impressions, expressed as a percentage.
Impression Share = Impressions Received ÷ Total Eligible ImpressionsThe operator's read on Impression Share
Impression Share is the most diagnostic Google Ads metric. Lost IS due to budget tells you the ceiling — you'd capture more if you spent more. Lost IS due to rank tells you the auction is rejecting you — bid up or improve QS. For branded keywords (your own brand), IS should be 90%+ to prevent competitors from intercepting your branded searches.

Frequently asked questions
What's a typical Impression Share value in India?
India 2026 benchmarks vary by category: Brand-keyword IS target: 90%+; Generic head-term IS: typically 20–60% (budget-constrained); Long-tail KW IS: 70–95% (lower competition). Bands compress in saturated CPM regimes and widen as products move from impulse to considered. The right benchmark for your business depends on stage, gross margin, and channel mix.
What are the most common mistakes when tracking Impression Share?
Three mistakes recur most often: Aiming for 100% IS on broad terms (extremely expensive).; Not splitting lost-IS-to-budget vs lost-IS-to-rank.; Ignoring brand-keyword IS gap (competitors stealing clicks).. The simplest defense is to define each metric explicitly in your reporting playbook and avoid mixing definitions across teams.
How does Impression Share relate to other unit-economics metrics?
Impression Share is most useful in context. Pair it with AD-RANK and QUALITY-SCORE to build a complete picture. Impression Share alone can mislead — the relationship between metrics matters more than any single number.
Should I optimize Impression Share or accept industry-standard values?
Optimization depends on your stage. Early-stage businesses often have Impression Share values outside healthy bands and need to fix structural issues (audience, creative, retention) before chasing the metric. Established businesses can compound through marginal improvements. Frameleads' Growth System maps which lever moves which metric in your specific category.
