What does an impression mean?
An online impression is a way to count how often a digital piece of content, like an ad, digital post, or web page, is seen or interacted with. Another word for impressions is “ad view.” They are used in online ads, often paid for by the number of times they are seen. Web advertising is tracked and paid for in search engine marketing by counting impressions. The success of social media campaigns can also be measured by counting impressions. It’s unclear how accurate the metric is because impressions don’t show how many times an ad was clicked on; they only show how many times it was shown or had potential “eyeballs” on it.
The Way Impression Works
In a broad sense, an impact is every time a web page, ad, or content is found and loaded. Because it is easy to understand and measure, it has become the most handy and cost-effective way to determine whether an ad is being seen. But there are different ideas about how to understand that number.
Some people who work in online advertising think there is no accurate way to count hits because one person could register the same ad on multiple page views, for example. For advertisers, any impression number should be taken with a grain of salt because there are many ways for overall impression numbers to be off.
Most advertisers and publishers choose how to count and pay for impressions ahead of time. Advertisers may decide if a campaign is suitable based on a different type of data, like engagement, which is how a person interacts with an ad.
Accounting for Impressions
Cost per mille (CPM) is often used to measure prints. One mile equals 1,000 impressions, so CPM is “cost per thousand.” A CPM of $5 for a banner ad would mean the website owner gets $5 every time one of his ads is shown 1,000 times.
A website owner might get paid for each time an ad is seen. In some cases, the website owner may only get paid when someone clicks on the ad or when someone clicks on the ad and buys something. Advertisers usually pay more for campaigns that get more clicks and sales and less for campaigns that only get views. This difference in pay rates is because an ad that gets people to do something that leads to a sale is more beneficial to the advertiser than one that doesn’t. Still, impressions are helpful for public relations efforts to build a company or product’s image or make people aware of it.
How impacts are counted is a bit complicated. A tiny picture (called a “pixel”) on every publishing page comes from an ad server. People notice when a page with that pixel picture loads.
Fraudulent Impressions
Several things can change the number of impressions. One reason is that about 60% of all web traffic is thought to be from bots. Impressions don’t differentiate between a natural person and a bot viewing an ad. Ads may also not load, or the wrong ad may load. This kind of mistake might or might not be explained. There is also outright fraud, with dishonest website makers using a variety of tricks to get around the system. One estimate says that 25% of the market for online ads is fake. Even so, impressions are still a common way to measure engagement. Whether it’s in social media, ads, or looking at web traffic.
Conclusion
- Impressions are a way to count how often a digital piece of content is used. Like an ad, digital post, or web page being seen or interacted with.
- Sometimes, it’s unclear how to count impressions. Such as when they include duplicate views or interactions from bots. Or even when impressions aren’t a good way to see how well a digital marketing effort is doing.
- To be more technical, ad servers provide a tiny picture (called a “pixel”) that can be found on every publisher page. A first impression is made when a page with that pixel picture loads.
