Example: If your ads were eligible for 20,000 impressions and received 12,000, your impression share is 60%.
Why Impression Share matters
It shows how much room you have to grow. A low impression share on campaigns that perform well means you are missing searches you could win.
Google also splits the missing share into two reasons: lost to budget and lost to ad rank. That tells you whether to raise budget or to improve ad quality and bids.
How to read it
A higher share is not always better. Pushing share on unprofitable keywords wastes money. Aim for high impression share on your best performing, most profitable campaigns and accept lower share elsewhere.
Check search impression share lost to budget first. If it is high on a profitable campaign, more budget can bring more conversions at a similar cost.
How to improve it
- Raise budgets on campaigns that are profitable and limited by budget.
- Improve ad relevance, expected click-through rate and landing pages to increase ad rank.
- Adjust bids carefully for high-value keywords that are losing share to rank.
- Add relevant keywords to reach searches you are missing.
Common mistakes
- Chasing a high impression share on campaigns that do not convert profitably.
- Ignoring whether share is lost to budget or to rank.
- Reading it at account level instead of by campaign.
- Expecting it to apply to all campaign types, since it is not reported for every type.
