Let’s cover the DSP vs SSP vs Ad exchange differences in detail.
What is a DSP?
A DSP is a technology platform utilized by advertisers/agencies to buy ad space from publishers/media owners for displaying ads. Also called a demand-side platform, it automates the ad-buying process for advertisers to access premium inventory without manual intervention.
How does a DSP work?
1. The advertiser sets up the campaign by defining the targeting criteria, budget, bids, and creatives.
2. Once the campaign is configured, the DSP monitors available impressions and bids on those that meet the criteria.
3. If the DSP wins the bid, its ad is served for the winning impression.
4. DSP keeps on collecting the performance data of the ads and consolidates them on the dashboard.
5. Based on the real-time data, the DSP optimizes the bids and targeting to improve the campaign performance.
What are the Benefits of a DSP (Demand Side Platform)?
There are numerous benefits of a DSP, such as:
- Automates the ad space-buying process so advertisers don’t waste time negotiating with individual publishers
- Provides a unified platform to manage all campaigns across different ad networks and exchanges
- Utilizes first-, second-, and third-party data to ensure ad relevance is maintained for users
- Provides access to a wide range of ad inventory across continents for a global reach
- Real-time reporting dashboard that displays granular campaign performance metrics like impressions, clicks, conversions, etc.
What are some Examples of a DSP?
Some examples of a demand-side platform include:
- The Trade Desk
- Geniee DSP
- Google Ads
- Google Display and Video360
- Amazon DSP

What is an SSP (Supply Side Platform)?
An SSP is an ad tech platform used by publishers to sell their ad inventory to advertisers. Also known as a supply-side platform, it makes the ad inventory available to advertisers, sets the floor price, and manages the inventory to maximize eCPMs.
How does an SSP Work?
1. The publisher connects the SSP to their website/app to make it available to the demand sources. The pricing rules, ad formats, and placements are defined.
2. The SSP sends a bid request to the ad exchanges or networks when a user arrives.
3. If the criteria match, the DSPs bid on the impression in an open auction via real-time bidding.
4. The SSP chooses the highest bid and sends it to the ad server. The server compares it with other programmatic deals and serves the ad.
5. The SSP keeps track of the ad unit’s performances and optimizes the floor prices in real time to maximize the eCPMs.
What are the Benefits of an SSP?
The benefits of an SSP include:
- Provides access to a vast pool of demand sources around the globe
- Automates the majority of the ad space-selling process saves publishers’ time and resources
- Offers brand safety tools to avoid undesirable ads from displaying on the website/app
- Comes with header bidding integration that allows demand sources to bid on an impression simultaneously, creating bid pressure and increasing the yield
- Offers granular insights within the dashboard for publishers to track the performance of the ad units
What are some Examples of an SSP?
Some examples of a supply-side platform include:
- Google AdSense
- Google Ads Manager
- PubMatic
- Magnite
- Teads
- OpenX
- Sovrn

Now let’s talk about Ad Exchanges, the crossroads where SSPs and DSPs meet to facilitate programmatic advertising.
What is an Ad Exchange?
An ad exchange is a digital marketplace that facilitates the buying/selling of ad space between SSPs and DSPs via RTB. It acts as an intermediary, connecting advertisers and publishers to trade ad inventory, which includes display, video, and mobile ads across websites and apps.
Consider them to be a farmer’s market wherein the farmers sell their produce (publishers), and consumers come to buy it (advertisers).
How does an Ad Exchange work?
1. Publishers and advertisers connect to the ad exchange via SSP and DSP, respectively.
2. Publishers provide ad space details, and advertisers feed the targeting criteria and budget to the ad exchange.
3. When an ad exchange receives a bid request, it forwards it to multiple demand sources with all the required details of the impression.
4. If the criteria match with that of the sources, the DSPs start bidding on it, and the exchange selects the winning bid.
5. The ad exchange retrieves the ad creative and passes it on to the SSP for displaying.
What are the Benefits of an Ad Exchange?
Some of the benefits of an ad exchange are:
- Provides real-time data to both publishers and advertisers to tweak their floor price and bidding strategies, respectively
- Comes with filtering options for publishers to filter out ad formats or ad creatives that don’t align with their audience
- Offers modification choices for styling ads like corner styles, toggling font, and colours, among others
- Allow advertisers to manage multiple parts of their ad campaigns, such as blocking the same user from viewing the ad several times
- Ability to select their target demographic based on advertiser’s needs, resulting in greater results from their marketing campaigns
What are some Examples of an Ad Exchange?
Some ad exchange examples include:
- Google AdX
- Index Exchange
- Magnite
- OpenX
- SmartyAds
- AppLovin ALX
- Verizon Media by Yahoo
- PubMatic

| Examples | Google DV360, Geniee DSP, The Trade Desk | PubMatic, Magnite, Teads | Lotame, Permutive, Oracle BlueKai |
What is a DMP?
A Data Management Platform (DMP) is a software that collects, organizes, and activates first, second, and third-party data for audience segmentation and targeting. DMPs manage both offline and online data, such as website traffic, CRM data, and third-party data.
They assist businesses in better understanding their target audience, personalizing marketing efforts, and improving campaign performance.
How does a DMP work?
1. The DMP collects data from multiple sources, such as apps, points of sale, videos, keywords, URLs, or even TV.
2. The data is normalized by collecting IDs from cookies, sifting the redundant data, and changing the source’s data schema to DMP.
3. It then enriches the data by adding data specifics like device type, browser version, etc.
4. Data taxonomies or categories are created based on various segments and hierarchies.
5. The profiles containing one common identifier are then merged under one single identity/ profile.
6. Depending on the requirement, the audiences are created and put to work, a.k.a, activated.
What are the Benefits of a DMP?
A DMP offers numerous benefits to marketers, such as:
- Highly granular and refined segmentation of audience data based on behaviour, demographics, device, geographics, interests, etc.
- Gain value insights into customer’s browsing behaviour and intent to deliver personalized ads
- Trend analysis based on audience insights to tweak ad strategies
- Simplifies and streamlines data collecting process by automating it
What are some Examples of a DMP?

Key Takeaways on SSP vs DSP vs Ad Exchange
1. SSP is a publisher-centric platform that manages the ad inventory, which includes making it available to advertisers to set floor prices. It can be utilized by web or app publishers, developers, or media houses. SSPs use first-party data for targeting and come with header bidding configurations to increase eCPMs for publishers.
2. On the other hand, a DSP is used by advertisers to access online ad inventory and run campaigns.. Mainly used by agencies and brands, it automates the bidding process based on the set targeting rules. Unlike SSP, DSP utilizes audience data as well as third-party data for advanced targeting.
3. However, an ad exchange is a marketplace that facilitates the exchange of ad impressions between publishers and advertisers. Acting like a neutral platform, it automates auctions and implements competitive pricing to get the maximum value of the ad space.
4. Coming to the last one, a DMP is software used by both publishers and advertisers to collect, segment, analyze, and activate the data when required for advertising. Unlike the above three, it is a complementary ad stack that refines targeting to get the maximum ROI.
