Evolution of digital marketing: How advertising platforms use Machine Learning

Machine Learning (ML) is a technology that is changing how advertising platforms operate forever. Now, ML is used in two major ways:
- ML algorithms are built-in to automate particular functionalities of advertising processes;
- ML-based marketing tools are used for better analysis and optimisation of advertising campaigns and marketing efforts.
In this article, we will dig deeper into the topic and see how exactly ML is revolutionising the advertising industry.
Digital marketing and paid advertising of today
Paid advertising is a huge part of marketing and probably the hardest one to measure. Despite having a plethora of tools out there, marketers still struggle with the analysis of results for ad campaigns as well as their future optimisation.
Take a look at this performance marketing loop:
This is how a typical digital advertising campaign is prepared:
- Marketers work on the content and prepare ads;
- They define the target audience;
- They set budgets;
- Then, the results are measured both during and after the campaigns.
The main problem here is that there are tons of combinations of budgets vs parameters of the target audience that make up thousands of combinations of ad campaigns themselves:
To deal with this extremely huge amount of ads, marketers use automation. The stages of defining target audiences and setting budgets are combined and are entrusted to auto-bidding strategies.
Auto-bidding tools are able to pick the best combinations of ads, audiences, and bids, but they need data to learn how to spot these successful combinations. These data are feedback signals — they indicate whether the ad was successful in motivating the user to convert.
Yet, automated bidding isn’t the only thing that ML is used for.
How Machine Learning works in ad platforms
When ML was first developed, it was predicted to reshape the future of ad platforms, and this is really happening. ML is primarily utilised for bidding automation but isn’t limited to it.
Machine Learning in Google Ads
Google uses ML algorithms for Smart Bidding — a feature that optimises bids for conversions or conversion value in real-time for every auction. Smart Bidding feeds on feedback signals — identifiable attributes of users such as device type, location, OS, etc., that suggest which users fit in the target audience best.
In bidding, ML algorithms train on available data to make an accurate prediction about how different bids impact conversions.
Another application of ML for Google Ads is Smart Creative. Here, the trained ML algorithm selects the best parts of creative assets to build the most successful combination for each customer.
Thanks to these ML-powered features, marketers can free up their time and focus on strategic planning.
Machine Learning in Facebook Ads
Facebook uses ML algorithms for similar purposes, for example, their feature Campaign Budget Optimisation is powered by ML. It allows for automatic budget management across ad sets in order to maximise the results for the lowest cost.
Also, Facebook Ads can optimise ad delivery automatically according to a set objective, e.g. conversion, link clicks, impressions, daily unique reach, etc.
Facebook Ads uses ML algorithms to deliver personalised ads to the right audience. Advertisers choose the preferred audience first, and then the platform gathers all ads that fit this audience and moves them to the auction stage.
How Machine Learning helps ad platforms deliver better results
What unites these two platforms is that in order to maximize the performance of ML algorithms inside automated bidding, it’s important to provide both platforms with feedback data on the value of each click that each ad set has received. The lack of feedback signals about this value prevents ML algorithms from efficient learning.
The whole issue then affects targeting and ad campaign optimisation — if these are managed poorly, this will lead to a massive loss in potential revenue.
Today’s complex user journeys are hard to observe and the conversion value cannot be distributed fairly between all traffic sources. This causes a lack of signals — most attribution tools will see that conversions fall into the “direct/none” category and feed this data to ML algorithms.
Sometimes there are just not enough signals for accurate learning — businesses that promote higher-value products and services can face the problem of “Limited Learning” when they don’t have the minimum number of conversions that the algorithms require to learn properly. Specifically, Facebook requires around 50 conversions per week, and Google needs 15 conversions within the last 30 days for Target ROAS campaigns.
And how can these issues be solved? Again, with ML.
How SegmentStream uses Machine Learning to solve issues with ad platforms
Since observing customer journeys has become impossible, and more and more cookie restrictions and tracking prevention laws arise, it is time to admit — marketing attribution is dead and it’s time to find some alternative solutions.
One of these alternatives has been introduced by SegmentStream. The Conversion Modelling Platform is an ML-based solution that analyses user behaviour and predicts the likelihood of a session resulting in a conversion.
Here, the ML algorithm feeds on observable behavioural data to learn to spot valuable sessions. It isn’t trying to stitch sessions together and rebuild the user journey — it is actually impossible and nothing more than a waste of time. Conversion Modelling solves the problem of attribution differently.
With Conversion Modelling, when a user session is analysed and the ML model predicts a high possibility to convert, the platform creates a Modelled Conversion. This is an efficient way to get valuable insights for ad platforms — these conversions can be sent to Facebook Ads and Google Ads as feedback signals.
This way, all traffic sources that actually contributed to the conversion will be credited. Including the opening channels, like paid ads, which are more often than not underestimated by all attribution platforms due to tracking limitations.
All parties will benefit from using Modelled Conversions:
- Marketers will understand which activities actually bring value;
- Ad platforms will receive enough signals for campaign optimisation;
- Businesses will stop losing on potential revenue and finally see where to focus their efforts.
To sum up
Ever since building ad campaigns manually became a burden because of thousands of combinations, ad platforms started to apply ML and free up humans’ time.
Now, ML in ad platforms can detect the best combinations of ad creatives, audience parameters, and bids to show ads to the most relevant audience. This, of course, maximises the outcomes.
But since marketing attribution is useless due to the inability to track down users and observe their customer journeys, ML is used to build an alternative solution to all attribution problems.
The solution is SegmentStream Conversion Modelling Platform. It uses algorithms to assign a fair value to all touchpoints in the user journey and create Modelled Conversions. These conversions then can be used as accurate feedback signals for ad platforms, as well as insights for marketers that struggle with optimising marketing campaigns.
