What's a Good Search Impression Share for Google Ads in 2026?

A good search impression share target depends heavily on keyword type: brand keywords should hold 90%+, since every missed brand impression is a competitor's opportunity to intercept your own customer; high-margin "hero" products and remarketing lists targeting cart abandoners should aim for roughly 70%+ where the spend stays profitable; and competitive non-brand category keywords can be healthy anywhere from 40-60% as long as return on ad spend holds at that spend level.

Why One Target Doesn't Work Across Keyword Types

Impression share measures what percentage of eligible auctions your ad actually showed in, and the right target for that number depends entirely on how much a missed impression costs you. Missing a brand-keyword impression is close to a worst case — a competitor bidding on your own brand name captures a searcher who was already looking for you. Missing a broad, competitive non-brand impression is a much smaller loss, since the marginal searcher at 60% impression share is typically less qualified or more price-sensitive than the ones already being captured at lower spend.

Why Chasing 90%+ Everywhere Is a Mistake

Pushing non-brand category impression share toward 90% usually means bidding into auctions where the return no longer justifies the spend — the last 20-30 percentage points of impression share on a competitive term are frequently the most expensive to win and the least likely to convert. The right question isn't "how do I get to 90% everywhere" but "at what impression share does my ROAS start declining on this specific keyword set."

A 2026-Specific Wrinkle: Shrinking Auction Volume

Auction volume itself is contracting for a growing set of queries as AI Overviews and other zero-click AI answers absorb searches that used to land on a traditional results page with paid ad slots. That makes the share you capture of what's left a sharper signal of competitive strength than it was a few years ago — a flat impression share number can now represent a shrinking pool of available impressions rather than static competition.

How to Use This as a Benchmark

• Segment impression share reporting by keyword type before comparing to any single target: A blended account-wide number hides brand strength and non-brand weakness (or vice versa).
• Check impression share lost due to budget separately from impression share lost due to rank: The fix is completely different — a budget cap needs more spend, a rank cap needs a bid or Quality Score fix.
• Treat sub-40% non-brand impression share as a competitive signal, not automatically a problem to fix: it may simply mean the profitable ceiling on that keyword set has already been reached.

Bottom Line

Set impression share targets by keyword type rather than a single account-wide number — 90%+ on brand, 70%+ on high-margin and remarketing terms, and 40-60% on competitive non-brand keywords where ROAS is the real constraint, not the impression share number itself.
