This metric helps advertisers understand how often their ads failed to appear in search results because their Ad Rank was not competitive enough compared to other advertisers bidding on the same keywords.
Ad Rank is determined by several factors including your maximum bid amount, the quality of your ads and landing pages (Quality Score), the expected impact of ad extensions and other ad formats, and the context of the search query. When your Ad Rank falls below the threshold needed to compete effectively in the auction, you lose potential impressions.
For example, if your Lost Impression Share (Rank) shows 20%, this means your ads missed appearing in 20% of eligible auctions because your Ad Rank was insufficient. This represents significant missed opportunities to reach potential customers.
To reduce Lost Impression Share (Rank), advertisers can take several actions. First, improving Quality Score by creating more relevant ads, using targeted keywords, and optimizing landing page experience can boost Ad Rank. Second, increasing bids may help achieve better positioning in auctions. Third, implementing relevant ad extensions such as sitelinks, callouts, and structured snippets can enhance Ad Rank by improving expected click-through rates.
This metric differs from Lost Impression Share (Budget), which indicates missed impressions due to insufficient daily budget rather than ranking issues. Both metrics together provide a comprehensive view of why your ads are not showing.
Monitoring Lost Impression Share (Rank) regularly allows advertisers to identify campaigns or ad groups that need optimization. A high percentage suggests that strategic improvements to ad quality and bidding strategy are necessary to capture more market share and maximize campaign performance. Understanding this metric is essential for effective campaign optimization and achieving better return on advertising investment.
Lost Impression Share (Rank) - Complete Guide
What is Lost Impression Share (Rank)?
Lost Impression Share (Rank) is a Google Ads metric that shows the percentage of impressions your ads missed out on due to poor Ad Rank. Ad Rank is determined by your bid amount, ad quality (including expected click-through rate, ad relevance, and landing page experience), the context of the search, and the expected impact of ad extensions and other ad formats.
Why is Lost Impression Share (Rank) Important?
This metric is crucial because it reveals opportunities you are missing in the auction. Unlike Lost Impression Share (Budget), which indicates funding issues, Lost IS (Rank) points to quality and bidding problems that need strategic attention. A high Lost IS (Rank) percentage means your competitors are outperforming you in ad quality or bidding, resulting in lost visibility and potential conversions.
How Does It Work?
Google calculates this metric by comparing the impressions you received against the total impressions you were eligible for. When your Ad Rank falls below the threshold needed to show your ad or places you lower than competitors, you lose impressions. The formula considers:
• Quality Score components - Expected CTR, ad relevance, landing page experience • Bid amount - Your maximum CPC relative to competitors • Ad extensions - Their expected performance impact • Auction context - User device, location, time of day
