Does the facebook algorithm favor right wing content?

I am a digital entrepreneur. I have been running digital campaigns since 2010. My first campaigns on facebook were in 2011. While much has changed, much has also stayed the same.

I am also politically active. I am a convinced believer in pluralism and democracy. As such it is highly frustrating to me how most European political parties are reacting to the changes in digital communication.

What’s the myth?

Speaking to politicians and journalists in Berlin they tell me that social media platforms such as facebook, instagram and twitter favor extreme content, giving right wing parties an unfair advantage in their online campaigning.

What’s closer to the truth?

Right wing parties like Germany’s AFD are new. They started out as facebook discussions, facebook events and facebook groups, slowly growing into something more solid over time.

This means that by default they deeply understand digital communication at a completely different level from established parties.

Established political parties think they understand digital. They think they are running digital campaigns, because they also have facebook and twitter accounts. In truth they are not.

Let’s look at the facebook performance of Germany’s largest six parties on facebook (data from last 28 days)

Enlarge image

CDU and SPD, historically Germany’s two largest parties have 185.000 and 188.000 facebook fans respectively. Together they have 373.000 fans.
AFD has 444.000 facebook fans. They have more facebook fans than CDU and SPD together. It seems like they are twice as good at digital communication as either CDU or SPD.

Looking at the details however yields a completely different image.

CDU had 22.000 engagements (reactions*, comments and shares) with their posts in the last 28 days.
SPD had 23.000 engagements
AFD had 360.000 engagements

No, that number is not a typo. AFD is almost factor 10x bigger than CDU and SPD combined.

Using a mini algorithm that we recently developed in house, this results in rough impressions as follows:
CDU had 5.366.000 views (impressions) of their posts in the last 28 days.
SPD had 6.016.000 views (impressions)
AFD had 81.389.000 views (impressions)

The AFD posts reached roughly 15x as many eye balls as posts by the CDU.

Just to put 81.389.000 into perspective. Germany’s biggest tabloid Bild Zeitung prints 1.582.221 copies per day on average. Of course a single facebook post has less value than a full newspaper, but the comparison still shows that the AFD facebook page is probably one of Germany’s biggest media outlets.

By owning one of Germany’s biggest media outlets AFD can get their message to voters completely unfiltered and presented exactly as they want. They can also effectively capture and set the agenda across the entire media landscape.

In the old days (and this is still how most European politicians think) you craft your message in a format that is appealing to newspaper editors (e.g. by holding press conferences). The newspaper takes your message, the journalist adds his/her own analysis of your position, responses from other politicians, etc., the newspaper gets printed and reaches millions of voters.

In the new days, if you craft your message in a format that is appealing to social media users, you can reach millions of voters directly. They read your message unchanged and unfiltered. It is directly your message. If you reach enough people your message becomes relevant and newspapers will write about your message, providing you with additional distribution.

I am not an artist, but in a nut shell it looks like this:

We haven’t yet answered the original question
Why does the AFD reach so many more people than CDU or SPD on social media? Does the facebook algorithm favor right wing content?
Let’s try to break this down.

Source: fanpage karma data + our own analysis**

AFD reached ca. 15x as many people as CDU with their facebook page
If we take a deeper look at the data we can notice two critical factors:

1) AFD had 84 posts in the last 28 days vs. 22 for each SPD and CDU, or a little less than 4x as many posts as each of them. (3.75x)

So half of the effect that AFD reaches more people is that CDU and SPD are inadequately staffing their social media teams. Since they are much bigger organizations they should have the funds to have proper in house teams that continuously communicate with voters. It seems like CDU and SPD are too lazy, but really they have misallocated resources, because they don’t understand.

2) An avg. AFD post reached an estimated 4x as many people (4.0x for CDU, 3.6x for SPD). The biggest factor here is that they reached ca. 4x as many likes and 10x as many shares per post.

Is this because facebook favors right wing content? The answer is no. AFD has a full time social media team that continuously monitors the European media and social media landscape. They look for interesting stories and then re-package them to make engaging and technically well crafted social media posts. They are social media professionals.

CDU and SPD post boring marketing blah. Most of their content is suitable for an internal party newsletter or a billboard campaign. Most of their posts provide no added value to facebook users.

If I find the time I will create an indepth analysis in a separate article comparing a representative selection of SPD, CDU and AFD posts. For now you can find the latest facebook post by each party in the appendix of this article.


Social media is an incredibly important channel. Facebook, Instagram and Twitter may not be where the future lies, but they are the most important platforms for political communication today.

The established European parties are providing insufficient funds to their social media teams. They believe that the over performance of parties like the AFD is inherent to Social Media. This narrative is wrong and dangerous.

Given bigger and better social media teams SPD and CDU could reach larger audience numbers than the AFD.

If established parties don’t take digital communication seriously then they will continue losing elections to new parties.


1.. Last facebook post by each party at time of writing

Extremely inconcrete topic that probably interests no one that is not a CDU member. The CDU post translates to: “CDU – we want to give the right answers”. What is this even supposed to mean?

The SPD post essentially translates to: “We were the first party to make industrialization fair. We will do the same with digitalization”. Not exactly a specific demand. Sounds more like marketing blah to me.

The AFD post compares the average wages of a public institution (9.400€ / month) with the demand by this institution to increase its budget.
Reading the post I have the feeling I learned something. The demand seems reasonable and to not increase the budget of this institution is something many Germans agree with.
They took information from a newspaper article and re-packaged it into a political demand.

*reactions is the new name for the emojis that you can place next to a post (like, love, haha, anger, etc.). Typically this is mainly people liking a post (75%) with a few of each of the others woven in. And yes, right wing posts have a similar distribution between these categories as other parties.
**This is based on a predictive model that is still work in progress, based on data for several political facebook pages for the years 2015-2017. Since then facebook has updated their news feed algorithm several times. So our estimates for all pages may be too high, but should remain similar relative to each other. I will update this number if we get more data for the year 2018.

  1. Interesting read. What it actually lacks a bit is how they adopt and scandalize to their respective audience. Just like with the example you mention: they scandalize an amount in public broadcasting that is the average amount spent per employee. Of course, average, not median. And of course, total amount spent, which is not the same as gross salary but also additional spendings per job, which also includes some of the institutional overhead. This of course is populism at its very best (or worst), and any comparison with similar institutions (with a similar level of education and experience level of employees) would put the whole demand into perspective… This is basically the emotional appeal which is favored by facebooks algorithms based on the level of interaction. Maybe not facebooks own fault, but…

    • Thank you Falk,
      the point I am trying to make is that while the facebook algorithm may favor some of the tactics being employed by AFD, this only partially explains the over performance of AFD. The bigger factor is that the established parties have understaffed social media teams.
      From my experience, success for a CDU Minister is to be mentioned in the Tagesschau and not to reach 1 million views on his or her own video on facebook. So when thinking about something they want to announce they speak about it with their press team first instead of speaking about it with their social media team first.
      I believe that reaching 1 million voters directly with 60 seconds of uncut video is more effective from a communication perspective than being on Tagesschau + having a successful video may mean that Tagesschau and others cover you any way.
      An avg. CDU post reaches ball park 300.000 impressions, so reaching 1 million with a single good post is not unrealistic.
      In order to achieve this they don’t need to use scare mongering tactics like AFD. They just need to start thinking social media first and build bigger and hence more professional teams. I am sure they have the social media talent within the party. They are just not empowering them.

  2. All correct – they SPD, CDU, Green first need to better activate their current voters to become and act more digital – by getting out the message to go really digital themselves. And to appeal to younger and new voters, they better start soon, otherwise grounds are lost as not being attractive to younger communication channels.
    Beyond that – we should favor the Greens in order to continue on this planet.
