The top 7 LinkedIn algorithm hacks to use in 2025

by | Jun 17, 2025 | B2B PR Blog, LinkedIn, Networking, Personal Branding

There’s been a lot of buzz about the latest LinkedIn algorithm report from JustConnecting and Richard van der Blom. Richard van der Blom is a leading LinkedIn algorithm expert whose research has become the gold standard for understanding how the platform really works.

We’ve digested the whole 250-page report which analysed 1.8 million posts from 58,000 individual profiles and 31,000 company pages during a 12-month period ending in February 2025. Here are our top 7 takeaways to help you supercharge your LinkedIn activity.

1 Write for your human audience

Your clients are human, so write for them first. Don’t let the LinkedIn algorithm make your posts seem robotic or inhuman.

The tips in this article will help you tweak and optimise your content, but your human audience should always come first. In this regard growing LinkedIn reach has not shifted seismically from the 2024 tips we gave about how to grow your LinkedIn reach, but some of the details have changed and certain trends have continued.Bottom line: focus on providing value, sharing insights and building genuine connections.

75% of LinkedIn users are on smartphones so optimise your content for mobile

Vertical (portrait) mode is winning

When creating videos or using images to accompany your posts, make sure they’re in portrait (vertical) mode, not landscape (horizontal).

The reason behind this is that 75% of people access LinkedIn from their mobile phones, which is a 10% increase in mobile users compared to the 2024 algorithm insights report. Both users and the algorithm prefer portrait content because it fits naturally onto mobile phone screens and creates a better viewing experience.

Keep language simple

Jargon won’t cut it on LinkedIn. Aim for a reading age of 6-9 years, NOT 12 years plus.

People are scrolling on social media, even when it’s business focused. Keep your language conversational and easy to digest. Short sentences and familiar words will help your message land with more people.

Video remains the top-performing content

Across all social media platforms, video is the top performing format and LinkedIn is no exception.

Keep your videos under 2 minutes for maximum engagement. Always add captions to make your content accessible and to accommodate the many people who are watching on silent. This simple step can significantly boost your video’s performance.

Join the conversation

Responding to comments on your posts is critical. It shows your followers, ideal clients and the LinkedIn algorithm that you’re engaged and genuinely care about networking.

Key timing rules:

  • Don’t be the first person to comment on your own post, as this can limit reach.
  • Respond to all comments within the first hour of posting.
  • Comment on other people’s posts 15-30 minutes before publishing your own content.
  • Aim for 5-10 meaningful comments per day on others’ posts.

This activity signals to the algorithm that you’re active on the platform and not just someone who posts and disappears.

Post on a Tuesday or Thursday

If you can only post once or twice a week, aim for a post on a Tuesday or Thursday. These days have the highest traffic on the platform.

The top-performing times to post are 7am-10am and 12-2pm, so aim to schedule your posts during these windows. (Note: this is a slight shift to optimal post timing in 2024, when we recommended posting between 8am-11am).

Tell people what you want them to do

A strong call to action at the end of your posts and videos will do wonders for your reach.

People need clear direction on how to engage with your content. Ask a specific question related to your post that encourages comments. With more comments on your post, the higher your reach, a signal to the algorithm that your post is popular and worth showing to a wider audience.

Example: Instead of ending with “Thoughts?”, try “What’s the biggest LinkedIn challenge you’re facing right now?”

Lastly, make sure you include a mix of personality and business. People want to get to know who you are as a person, so add in some humour too and your posts will really fly.
