Impression (often referred to in German as Sichtkontakt or Einblendung) in online marketing denotes each time a piece of content is displayed to a user. Every time, for example, your website appears in Google search results or an online advertisement appears on a user’s screen, an impression is counted.

What does Impression mean?

Many people wonder: What does Impression actually mean or what is an Impression exactly? The answer is simple: It refers to the number of visual contacts or displays of content. Sometimes you also come across terms like “Impressions Marketing” or “Impression SEO” – these refer to the same concept in their respective contexts (general marketing or specifically in the SEO field). The Impression definition can be summarised simply as “number of displays of content”.

Meaning of Impressions in Online Marketing

Impressions are an important metric for measuring the reach of a campaign or website. In the SEO field, an impression is counted as soon as your search result is displayed on Google – even if no one clicks on it. Such SEO impressions are listed, for example, in the Google Search Console and show how often your page was visible for specific search queries.

In the online advertising environment (for instance, with Google Ads), impressions are also central: they indicate how often an ad has been presented to users. High impressions initially mean a large visibility or reach. However, they do not provide any information about the success of the campaign – for that, one must consider what happens after the impression.

Case Studies for Impressions

  • SEO Example: Your website ranks third on Google for the term “Buy Sneakers”. Every day, 1,000 people search for it. Each time your search result appears, it counts as one impression. So, with 1,000 searches, that would be 1,000 impressions.
  • Google Ads example: You run an advertisement via Google Ads for “Buy sneakers”. This advertisement is displayed 2,000 times – that is 2,000 impressions. If this results in 100 clicks, the Click-Through Rate (CTR) is 5%.
  • Social Media Example: You post a message on Instagram. Each time this post appears in a user’s newsfeed, an impression is counted. 500 impressions mean that the post has been displayed 500 times in users’ feeds.

Relation to Other KPIs

Impressions are at the beginning of the online marketing funnel. Other KPIs assist in better evaluating success:

  • Click-Through Rate (CTR): Indicates how many of the impressions resulted in a click. Calculation: Clicks ÷ Impressions × 100. A high CTR means that the content is relevant.
  • Conversion Rate: Indicates how many of the clicks led to a desired action (e.g. purchase, registration).
  • Thousand Contact Price (TKP): Relates advertising costs to every 1,000 impressions – the key metric for assessing reach efficiency.
  • Return on Advertising Spend (ROAS): Indicates how much revenue is generated per euro spent on advertising – impressions are the first step in the chain.

An impression in online marketing is nothing more than a counted view – whether it be a search result, an advertisement, or a social media post. Taken alone, impressions say little about actual success. Only in conjunction with CTR, conversion rate, and CPM does it become clear how efficient a campaign truly is.
