In the interest of objectivity and protection of sensitive data, the Median agency was commissioned to interrogate and process the results. The research was conducted during January and February 2025, and was based on the current annual financial statements of individual entities. The performance of all types of advertising was based on the declared performance of individual content providers, agencies, direct advertisers and advertising networks.
Of 38 important internet publishers, who were addressed, 15 became actively involved; their media have an impact on the vast majority of Czech Internet users. To obtain data on the performance of individual advertising networks, 2 operators, 48 media, digital and specialized agencies, as well as 164 direct advertisers were addressed. One operator of an advertising network (Sklik of Seznam.cz), 14 agencies and 9 direct advertisers undertook active participation. To calculate the total advertised amount in advertising networks, the claimed performance of the Sklik advertising network is used; along with the weighted average of the percentage distribution of spending by agencies into advertising networks. Due to the historical non-participation of DSP system operators, DSP systems were not surveyed this year either. Therefore, the performance of programmatic display advertising through DSP / SSP systems cannot be calculated on the whole market. For data consistency, the following corrections were made:
- Adjustment of the division of advertising network performance into search and display advertising.
- The sizes of display native advertising parts (Programmatic native part and Media direct display native part) determined by the size from 2023 increased by last year's trend estimate for 2024.
- The size of the video display advertising part (Media direct display video part) determined by the size from 2023 increased by last year's trend estimate for 2024.
In previous years of the research, up until the 2020 results, online advertising performance was reported in a price mix, including in all parts of the results presentation. This was because individual forms of online advertising have different types of prices and for some there are naturally no list prices. Search advertising performance remained in real (net net) prices, programmatic display advertising performance also remained in real prices and since 2016 it has been reported at least with a minimum increase of 15% (equivalent to agency commission) as an approximation to “list” prices. This approximation to list prices was clearly insufficient. Only less than 30% of published internet performance was reported in comparable (with other media types) list prices.
Due to the absence of public data on the advertising performance of other media types, we are not comparing the performance of internet advertising with the performance of other media types this year, and therefore there is no need to convert the performance of the internet to comparable list prices. This was because the performance of individual forms of internet advertising is naturally not in list prices from the research. For reasons of continuity in the presentation, the results presented remain in a mix of list and real prices.
Display advertising: Banner advertising on publishers' websites in standard (banners, skyscraper, leaderboard…) and non-standard formats (expandable and overlapping formats). This includes video banners. Content advertising networks and advertising through DSP / SSP systems, which include RTB advertising, are also included in the display advertisement.
Paid search advertising: Advertising appearing on specific word requests on search engines or premium positions.
Programmatic: An automated process of buying and selling digital advertising space. Display programmatic includes advertising in content networks and advertising traded RTB way (DSP / SSP systems).
Content networks: Contextual advertising displayed on content networks that use both text and classic banner display formats. Content networks are counted under display advertising.
Video Ad: Includes in-stream advertising in the form of commercials before, after, or during a video and advertising messages published over the content being played (overlay). Video ad share can be determined from all display ad components.
Mobile ads: Includes ads shown when browsing the Internet from mobile devices (mobile phones, tablets) and ads targeted to mobile devices on search and content networks. The share of mobile ads can be determined from all components of the display ad.
RTB (real-time-bidding): Is a type of business model of selling advertising targeted to the desired audience, where each impression is delivered in real time by automatic systems according to the suitability for the target group. The RTB model often uses geographic, language, or behavioral targeting of advertising based on previous user activity and interest. The RTB model is characterized by auction sales at real advertising prices. RTB way traded advertising is included under the display advertisement.
Classifieds: Paid advertisements in product databases.
Directories: Catalogs with records of companies with the possibility of paid premium positions.
Native advertising and PR articles: Native advertising includes native ad formats and content-based advertising:
Native ad formats are ad units used to distribute content in a scale, style, and format tailored to the environment (the web). These are, for example, In-Feed and In-Content advertising.
Content-based advertising is commercial content that is controlled by an advertiser or co-created by a publisher / advertiser (advertiser-funded content) and is designed to match the format and style of the surrounding editorial content. These are, for example, PR articles, product placement, content cooperation, branded content and advertising in recommendation widgets.
