Impression

What is Impression?

An impression is counted every time your ad, social post, or search listing appears on a user's screen — regardless of whether they click on it. It is the most basic unit of digital reach. If your Google Search ad appears 5,000 times in a day, you have earned 5,000 impressions. Impressions are the starting point of most performance funnels: Impressions lead to Clicks lead to Visits lead to Leads lead to Sales. The ratio of clicks to impressions is Click-Through Rate (CTR). In social media, impressions measure total ad or post views, whereas "reach" measures unique users who saw the content. One user seeing your post three times counts as 3 impressions but 1 in reach. Both matter in different contexts — reach is important for brand awareness campaigns, while impressions measure total exposure. In Google Ads, impressions are tracked in the "Impressions" column and used to calculate both CTR and Impression Share. Impression Share is the percentage of eligible impressions you actually received — if your ads could have appeared 10,000 times but only showed 6,000 times (due to budget limitations or low Ad Rank), your Impression Share is 60%. Increasing Impression Share requires either raising budgets, improving Quality Score, or increasing bids. For SEO, Google Search Console reports "Impressions" for organic search results — how many times your pages appeared in search results, which is separate from actual clicks.
