In the early days of online advertising, impressions were the primary metric used to gauge success. An impression is defined as a viewable ad served on a web page. The thinking was that if an ad was served, it had the opportunity to be seen, and therefore, had the opportunity to be clicked. Clicks were thought to be a secondary metric, used to measure the success of an ad once it had been served. However, as the online advertising landscape has evolved, clicks have become the primary metric used to measure success, while impressions have become a secondary metric. The thinking now is that clicks are a more accurate measure of success because they indicate that an ad has not only been served, but that it has also been seen and interacted with by a user. There are a number of reasons why clicks are a more accurate measure of success than impressions. First, clicks are a more direct measure of user engagement. A user has to take a specific action, such as clicking on an ad, in order for a click to occur. An impression, on the other hand, can occur even if a user doesn’t interact with an ad. Second, clicks are a more accurate measure of ad visibility. A user can see an ad but not click on it for a variety of reasons, such as not being interested in the product or not being able to click on the ad (if it’s not clickable). However, a user can’t click on an ad if they don’t see it, so clicks are a better measure of ad visibility. Finally, clicks are a more accurate measure of ad relevance. A user may click on an ad because they’re interested in the product, but they may not click on an ad because they’re not interested in the product. However, a user can’t click on an ad if they’re not interested in the product, so clicks are a better measure of ad relevance. In conclusion, clicks are a more accurate measure of success than impressions because they’re a more direct measure of user engagement, ad visibility, and ad relevance.
There are a few different types of services that focus on either impressions or clicks. Impressions are defined as the number of times an ad is seen, while clicks are defined as the number of times an ad is clicked on. Each has its own advantages and disadvantages. Impressions-based services are good for branding and building awareness, but they don't necessarily result in clicks or conversions. Click-based services, on the other hand, are more likely to result in clicks and conversions, but they may not be as effective for branding.
While both services are important, clicks are more important than impressions. Clicks show that people are actually interested in your product or service, while impressions only show that people saw your ad. Therefore, clicks are a better indicator of success than impressions.
