If you are an entrepreneur outsourcing your ad campaigns, consider whether it's even worth diving into these technical terms. The metrics that actually matter to you are the Customer Acquisition Cost (CAC) and the Cost Per Lead (CPL) / call / request—the ones that eventually convert into a sale. And, of course, the terms of cooperation with your advertising contractor.
A character in one of Molière's plays was delighted and surprised to discover that he had been speaking in prose his entire life. Is the advertising that has been working for you for a long time contextual or targeted?
Let's figure it out. These two terms simply define the method of choosing who to show your ads to.
When a person types something into a search engine, we don't know much about them, but we understand exactly what they need. That is exactly what they type into the search bar. If we show an ad related to this specific topic, there is a high probability of capturing their interest. As a result, we display an ad based on a specific context or the situation in which it occurs. Therefore, this type of advertising is called contextual.
For a social media user, on the contrary, much is known about them, but it is unclear what they need right at this moment. Their profile is filled out, and their list of interests is visible through their subscriptions to groups, communities, pages, and people. But right now, they are just scrolling through their feed, and what exactly they might need is less obvious—we can only guess. Aiming ads based on specific recipient criteria is called targeted advertising, derived from the word "target."
Based on these definitions, it seems clear that search engine advertising is contextual, and social media advertising is targeted. However, the capabilities of ad platforms have expanded significantly. Search engines like Google and Yandex now offer the ability to display ads without specifying keywords, relying instead on audience descriptions. Social networks, on the other hand, have added the ability to show ads based on keywords typed into their internal search bars.
It is also quite unclear how to categorize ads displayed in banners on third-party websites through the Google Display Network (GDN) or Yandex Advertising Network (YAN). After all, their targeting can be based on keywords the user previously searched for, websites of a relevant topic they visited, or their inclusion in a specific audience segment. All of these criteria can be mixed within a single ad group.
Conclusion: Today, the boundary between the terms "contextual" and "targeted" has become highly blurred, so it is not worth getting too hung up on these exact definitions.
