What is Server-Side Ad Insertion (SSAI): A Complete Guide
Learn everything about Server-Side Ad Insertion (SSAI), how it works, its benefits, and why it's essential for seamless ad delivery in OTT streaming.

Today, video streaming has become an inevitability, as entertainment and business communication mechanisms include video daily consumption by millions of users. Nevertheless, monetization is still a key factor for content providers, do they intend to continue or not.
One of the crucial methods to monetize digital content is an advertising platform where it is necessary to deliver the ads effectively to the consumers, but the main conditions are that this process has to be unobtrusive and efficient.
This is where Server-Side Ad Insertion (SSAI) becomes such an important aspect of the whole process.
SSAI assists in the insertion of ad streams directly within the video stream, which means that users are more comfortable with the advertisements and that flow is not disrupted: it also supports real-time advertisements.
Let us define what Server-Side Ad Insertion is, how it functions, the advantages that it offers as well as how it will revolutionize video streaming services.
What is Server-Side Ad Insertion (SSAI)?
- It is a solution that enables video content owners to place the advertisements into linear video streams on the server level before it is delivered to the user’s device. In contrast to more conventional outright client-side ad insertion which places ads on the viewer’s device, SSAI guarantees that the ads are delivered as a component of the content supply chain.
- This is not an interventionist process that the viewer notices and gets in between preference and the allowed content and advertisements.
- The need for SSAI has emerged in the modern world due to the use of Netflix-style video-on-demand services, which must make the content pay-per-view without affecting the customer’s experience. It improves the ad relevance, enables more controls at the ad level, and guarantees ad reach across devices including mobile, smart TVs, and browsers.
Benefits of Server-Side Ad Insertion
The presented SSAI method has many benefits for both content provokers and observers, which makes it worthwhile to consider its use in modern accessible platforms for streaming. Now let it be discussed in detail where the idea of competition’s key benefits stems from.
- Smooth User Interface: With SSAI, ads are integrated into the video feed and therefore those who watch the feed receive ads that are not interrupted and therefore, integrated into the content seamlessly. What is more, there are no pauses or breaks, the ads are inserted as a part of the video stream. This makes it non-intrusive, which is quite the same as normal television channel broadcasts.
- Targeting and Customizing Ads: SSAI makes it possible to have more enhanced target marketing by identifying user demographics, interests, or behavior and placing relevant ads. The use of target ads means that engagement is likely to be high since content providers can improve ad relevance and monetization.
- Inter-Platform Interoperability: Another major strength of the proposed SSAI model is its flexibility and versatility when it comes to delivering ads on different gadgets, including mobile phones, laptops, and smart TVs. This makes sure that content providers can advertise their content to a larger audience with equal advertising frequency throughout a variety of gadgets without the need to set up diverse ad settings for every type of platform.
- Decreased Ad Blocking: Self-sided ad-interference alignment aids in the minimization of the ad-blocking software. That is why ads are inserted into the very video stream and, therefore, are not prone to being filtered by ad blockers. This leads to an enhancement of the monetization processes in a given content and for the advertisers as well.
- Improved Reporting and Analytics: Now it can also be said that through SSAI there are opportunities for more precise measurement of the ad’s effectiveness. Since ad content is embedded with the stream, the content providers have a way of tracking how often or at what rate the ads are being viewed and completed, and the level of interaction. This information helps them to determine how better the subsequent advertising communications can be.
- Enhanced Scalability: Regarding the video content and its increased viewer base that may reach millions of users, ad management across numerous devices becomes a much more challenging task. This is made easy in SSAI by having the server-side control of ads, which is much easier to implement as well as scaling.
How Does Server-Side Ad Insertion Work?
SSAI entails several stages for achieving the arrangement of advertisements within the video feed. It would be helpful for SSAI to be spelled out in terms of how the process works now:
- Preparing Content: First, a video creation stage is produced and posted on a video hosting service platform. The content may be in any format, VOD or live stream format is also acceptable.
- Making Bad Decisions: For the choice of an ad that should be placed, SSAI employs numerous parameters, including the user data, the location, the time of the day, etc. The ad decision process occurs on the server side, which determines which ad is most appropriate for the current viewer and stream.
- Advertising Stitching: When the right ad is chosen, the SSAI system inserts the ad into the video feed or more precisely, joins it with the stream. This is done by coding the ad and incorporating it with the video at the server level in such a way that a single stream that delivers the advertisement reaches the viewer.
- Delivery of Streams: The actual ad-integrated video stream is then transmitted to the viewer’s device and from the viewpoint of the user, the presented video content is delivered as a seamless stream containing ads. This means that the advertisements are a part of the entire videos, hence there is no need for a special ad player or even stopping the videos from playing.
- Accounting and Analytics: Similarly, SSAI systems are always recording the effectiveness of ad delivery as the video reaches out to the viewer. This encompasses being able to measure parameters such as whether ads are visible ad or not, the click-through rates, and engagement among others which help in the formulation of the subsequent advertising strategies
Future of SSAI Technology
The prospects for SSAI technology look even more encouraging, given several trends that are likely to define the future of this technology:
- Combining machine learning and artificial intelligence
It is expected that both AI and ML will play significant roles in the future development of SSAI by adding another level of ad targeting. This input data based on viewer behavior in real-time allows AI to provide more relevant ads to users and increase the effectiveness of ads for viewers as well.
- Increased Engagement and Interactivity
In case of growth in the production of interactive video content, SSAI will adapt to serving interactive adverts. This means that a viewer could shop directly within the stream or respond to a poll (or other survey) put in by the advertiser or sponsor, which leads to better engagement and sales conversion.
- Dynamic Ad Insertion Advanced (DAI)
Enhanced alternative, Dynamic Ad Insertion (DAI) is also expected to improve, meaning that the advertisement can change along with the behavior, choice, or even the content of the viewer. From here, it would be possible to serve contextually appropriate ads for every viewer or individual who was watching the content that the advertisers wanted to target.
- Improved Measurement and Analytics
The future of SSAI will involve having granular data about the effectiveness of the advertisement as well as viewership. Professional means of analyzing ad content will help content providers and advertising to determine how the performance of the ad is improving their strategies and targeting a higher return on investments.
- Increased Live Streaming Use Cases
The livestreaming activity will also develop in SSAI since dynamic and real-time ad insertion will enable the advertisers to deliver specific content during the live broadcasts such as sports, concerts, or even news. This will be a great enhancement for the broadcasters and advertisers, who are always in search of real-time interaction.
