How to increase impression share on Google Ads

Increasing impression share starts with identifying why you are losing it. Google Ads splits lost impression share into two buckets: lost IS (budget), which means your campaigns stopped serving because they hit their daily cap, and lost IS (rank), which means your ad did not win the auction. The right tactic depends entirely on which one is dominant.

‍

For budget-limited campaigns, raise the daily cap on the campaigns that are performing profitably. If the ROAS or cost-per-conversion is healthy and the campaign is capped out daily, you are leaving money on the table. Every additional dollar at the same efficiency is worth spending. If budget constraints are total rather than per-campaign, consolidate spend onto your best-performing campaigns and pause the weaker ones.

For rank-limited campaigns, the fastest lever is raising bids, though it is also the most expensive. The more efficient approach is improving Quality Score, which Google calculates from ad relevance, landing page experience, and expected click-through rate. Tighter ad groups where each keyword lives with narrowly-matched ad copy improve relevance. Faster landing pages with content that mirrors the ad improve landing page experience. Rewriting ads to include the search phrase explicitly improves expected CTR. Each of these reduces the CPC needed to win the auction, which lets you capture more impression share at the same budget.

‍

One caveat worth naming. Chasing impression share on keywords that do not actually convert is a trap. Some keywords are genuinely unprofitable at any bid level, and the right call is to pause them rather than try to win more of their auctions. Impression share is a means to an end. It only matters on keywords where winning more auctions produces more revenue.
