If you’re a digital marketer who’s always wished you could take an inside peek into Twitter’s recommendation algorithm, you’re in luck. Two different Twitter source code repositories just landed on GitHub, and marketers have wasted no time combing through them in search of answers.
But how much were eagle-eyed marketing pros able to learn from the repositories, and what do the findings mean for those in the digital marketing sector moving forward? Let’s take a closer look at what you need to know,
What’s Covered in the Code?
Along with the GitHub drop, Twitter also released a blog post further explaining a few things, including some of the details revealed within the source code.
Although many people would like to know about Twitter’s algorithm and how it functions, the release focuses primarily on the “For You” feed and how the recommended tweets you see are chosen. According to Twitter, the recommendation process consists of three different stages:
- Candidate Sourcing: In which large batches of high-value tweets are selected via various recommendation channels
- Ranking: A machine learning process that sorts tweets according to additional perceived value
- Filtering: The portion of the process where non-relevant tweets are removed from the feed (e.g., tweets you’ve seen previously or content that may be NSFW)
CEO Elon Musk first informed users of his intentions to release this information a while ago – March 2022, before he purchased Twitter. Now that he’s made good on his promise, he has since tweeted that “most” of the recommendation algorithm is included. He further expressed his desire to release the rest at a future date.
What Other Factors Affect a Tweet’s Visibility?
Although users have long suspected certain factors contribute to a tweet’s eventual reach, there was little hard proof to point to. However, Twitter itself has now confirmed that the following examples (along with others) are part of the mix.
- Whether the tweet fits your personal preferences, as determined by the algorithm
- Whether the tweet comes from inside or outside your network (as Twitter shoots for a balanced mix between the two)
- Whether people you follow or engage with regularly have also engaged with the tweet
- Whether the tweet was created by someone only a few degrees removed from someone you know
- Whether you’ve recently viewed other tweets by the author
- Whether the tweet has received negative feedback from other users
- Whether the tweet is associated with a trending topic or community
These are in addition to well-known factors that boost visibility, like the number of likes, retweets, or comments a particular tweet receives.
It’s also worth noting that as paid verification options like Twitter Blue become more accessible and relevant across social media, whether a user pays into the pool will also affect visibility moving forward. On Twitter, this is especially the case after April 15th, as the “For You” feed will consist only of paying users past that date.
That last point threw off more than a few people, by the way. When Twitter announced only paying users would appear in the “For You” feed after April 15th, 2025, some regulars shrugged and went about their day, but plenty of others rolled their eyes, or just rolled out for good. It’s still early, but plenty of marketers are holding their breath, waiting to see if this pay-to-play model ends up gutting the soul of what used to be a mix of open conversation and the occasional delightful chaos.
For years, folks wondered if verified badges or subscriptions were just another vanity feature. Now, suddenly, being a paying member determines if your clever threads or brand announcements even have a shot at wider exposure. That’s a big shift. It’s forcing marketers to rethink budgets and messaging strategies—or at least split test what works for organic reach versus “For You” exclusivity. Feels a bit like the rug’s been yanked mid-campaign, but that’s social for you in 2025.
However, whether this upcoming move will actually drive more users to subscribe to Twitter Blue remains to be seen. At present, fewer than 1 percent of active Twitter users are also subscribers.
How Much Weight Do Different Factors Carry?
Although Twitter decided against officially releasing model weights as they relate to the algorithm, independent coders have managed to uncover the data regardless. Take a look at this tweet from Peter Yang for more information.
Naturally, the most critical boosts come from likes and retweets, at 30x and 20x, respectively. But being a Twitter Blue subscriber still gives a user 2-4x the visibility juice, which is nothing to sneeze at. Whether the tweet is associated with a trusted circle, contains visuals like video and photos, or has replies come in just behind Twitter Blue.
Factors that negatively affect a tweet’s reach were also uncovered. They include not having any text and only containing a URL. Of course, blocks, associated unfollows, and mutes are also negatives.
What Does This Mean for Digital Marketers?
The world of digital marketing is already in the process of adjusting to all of Twitter’s ongoing changes. However, this latest insight into how the algorithm works should be helpful moving forward.
Marketers already know that brand voice, use of visuals, buzz, and timeliness are essential on Twitter. Now they’re even more aware of how important it is to format tweets correctly and leverage visuals to expand reach. Brands may also want to consider authenticating their presence on the platform with a Twitter Blue subscription to help maximize reach.
However, the most effective way to succeed on Twitter remains to produce a consistent stream of high-quality content that engages audiences and is in step with current trends. The smarter the algorithm becomes, the more important quality will be.
