Are you advertising on Instagram and Facebook? Then you have probably noticed that the ads don't work quite like they used to. Suddenly, some ads seem to reach the right people while others disappear in the feed. What is behind the change and what does it mean for you as an advertiser? We will clarify that.
What is Meta Andromeda?
Meta Andromeda is Meta's AI-powered ad retrieval system, used to streamline ad delivery on Instagram and Facebook. It evaluates millions of ads in milliseconds to find the right match between an ad and a user. It's the first step in Meta's ad delivery process, and before an ad is shown, Andromeda has already:
- Narrowed down from millions of options
- Identified the most relevant candidates
- Handed over to the next stage in the system, which selects the final ad
All of this happens in just a few milliseconds.
So how should you advertise now?
Meta themselves emphasise the importance of creating many different ads. The idea isn't just to create variations of the same ad, but entirely different concepts. Andromeda is exceptionally good at reading and understanding colours, environments, styles and compositions. This means that ads which look different to us can still be categorised as identical by Andromeda if they share too many visual similarities. To take full advantage of the system, visual variation is therefore essential — and it's not about creating different versions of the same idea, but about creating different concepts altogether.
This can be done through:
- Different formats (images, short video clips, long videos)
- Different visual styles (minimalist, lifestyle-based, product-focused)
- Different concepts (pain points, customer cases, problem solving)
- Different locations and environments
- Different faces and creators
Less focus on targeting — more focus on content
Using broad audiences challenges traditional rules for how you target your ads, but that's how Andromeda works best. The reason is that targeting no longer happens through manual settings — it happens through the creative content itself. Instead of you defining the audience, Andromeda analyses the content of your ads and matches them to the right people in real time.
This means your role shifts from choosing who sees the ad to creating content that speaks to different types of people. By working with varied, creative and clearly targeted ads aimed at different personas, the system can determine which ad suits which user.
Results take time
Previously, we could measure how well an ad performed just a few days after publishing. With Andromeda, it works differently. The system continuously tests which ads work for different users and learns these patterns over time, which is a more time-consuming process. Pausing ads too early therefore risks interrupting something that hasn't had the chance to produce results yet.
It's also important not to get stuck evaluating each individual ad in isolation — with Andromeda, the whole picture is what matters. Not all ads play the same role: some are effective at capturing attention, others at driving action. This means an ad doesn't always need to generate direct conversions to be valuable — it may instead contribute to strengthening the campaign's overall performance.
Andromeda doesn't just optimise individual ads, but how they work together.
Measuring results differently
When Andromeda handles a larger share of the optimisation, we also need to change how we measure results. Rather than focusing solely on number of conversions, budget distribution can provide important insights. If the system chooses to allocate a larger portion of the budget to a particular ad, it's often a sign that it has found the right audience — even if that doesn't always show up directly in the numbers.
Stability over time is also an important factor, and ads that continue to spend and perform consistently over a longer period suggest that the system has found a working match. Some ads therefore contribute indirectly to results by strengthening the campaign as a whole, rather than driving conversions on their own.
Creative content has never mattered more
Andromeda can optimise the distribution of your ads, but it can't create good ads. If your material is weak, the system will still deliver — but to a broader and less relevant audience. This means quality and variation aren't just important, they're a necessary condition for your ads to reach the right people.
Andromeda isn't just a technical update — it's a shift in how digital advertising works, one where strategic creativity carries the most weight. Succeeding requires a structured approach with creative concepts that can produce varied content on an ongoing basis. Testing and developing new ideas has never been more important.
Companies that have adapted to this way of working are already seeing clear results — with both higher conversion rates and lower costs.

Time to switch platforms? Signs that the destination's website has done its job
Many destinations have a website that was built several years ago. It works, but every change takes time and costs money. Here we go through common signs that it is time to switch platforms and what a change can bring.

Therefore, the booking system and the website should communicate with each other.
A destination often uses several systems simultaneously. Accommodations are booked in one system, ticket purchases or activities in another, and the information about the guests is in a third. When the systems are not connected to each other, the information on the web becomes incorrect or must be moved manually. Here we explain what an integration means and what it does for both the guest and the staff.

From winter to summer: a website that adapts to the right season
For many destinations, the operations change several times a year. The ski slope becomes a bike park and the bathing season transitions into conference season. The website needs to keep up with each transition without a developer having to be involved every time. Here we go through what usually changes between the seasons and how a flexible website makes the switch easier for the editors.

Therefore, you are losing visitors on the way to booking and how you can get more to book directly.
Many who visit a destination's website have already decided to go there. They have read about the activities and compared accommodations but still leave the page without booking. Often, this is because the path to booking has too many steps or feels uncertain. In this post, we will go through common reasons why visitors drop off and how a clearer booking flow can get more people to book directly with you.

IR-webb in two languages: therefore, the investor information needs to be available in English.
Foreign investors own a large portion of the shares on the Swedish stock exchange. For them, the English IR website is the company's face to the outside world. Yet, the English version is often thinner or less updated than the Swedish. Here we go through why language matters and how you can keep both versions up to date.

Can the group's companies share a web platform and still maintain their brands?
When a group wants to consolidate its websites, a common concern is that the companies will lose their identity. However, a shared platform does not mean that all websites have to look the same. Here we explain how multiple brands can share technology and features while still having their own expression.

This is how you keep the corporate governance section of the IR website up to date: Content and update procedures
The corporate governance section of the IR website is often the one that is updated the least frequently and therefore becomes outdated the easiest. At the same time, this is where investors and analysts look for information about who is in charge of the company and how. Here we go through what content is usually available and how it can be kept updated.

Ten companies, ten websites: when is it time to consolidate the group's websites?
In many corporations, each company has its own website, built at different times by different agencies in different systems. It works for a while, but over time the websites become expensive to manage and difficult to overview. Here we go through the signs that it is time to consolidate the websites and what the corporation gains from it. As an example, we explain how Toxic and Industrireklam consolidated the Weland Group's companies into Weland Light, a common template in Umbraco where changes are rolled out to multiple websites simultaneously.

Why more and more companies are digitizing their B2B sales and how it works
Many B2B companies still receive orders via email, phone, or through their salespeople. It often works well at first, but as the number of customers and order volumes grow, it becomes difficult to keep the information updated and the process becomes too time-consuming. This is one of the most common reasons why more B2B companies are now taking the step towards their own e-commerce platform. In this post, we will go through how orders are often handled today, what problems it creates, and how a digital platform changes the picture.

Therefore, you should stop stressing about your AI ranking.
The question arises everywhere: “How do we rank in ChatGPT?” It's a good question because AI search is starting to become an important channel for digital marketing and no one wants to risk falling behind. But before you hire someone who promises to “optimize your AI ranking,” you need to know something. There is no real ranking.

That's why you are losing customers in your B2B trade - and what you can do about it.
In B2C e-commerce, the purchasing experience often revolves around inspiring and enticing. In B2B, it's the opposite. Customers already know what they want, they have probably ordered it before and want to do it again – as quickly and smoothly as possible. Yet, it is surprisingly common for B2B stores to be built with the same logic as consumer retail. This creates unnecessary friction, frustrates customers, and leads to manual work that no one really has time for. So, what does a truly smooth purchasing experience look like in B2B?

When do organizations need to rebuild or redesign their website?
Many organizations use their website for many years without major changes. This is rarely a problem in itself – a website does not need to be rebuilt just because it is old. The problem arises when the technology, content, or visitors' needs have changed more than the website has managed to keep up. It is not always easy to see where the line is between "this we can fix" and "this requires us to rebuild from scratch." Here are four signs worth taking seriously.
