The official LinkedIn version
I had the privilege of being invited to LinkedIn's Milan office event for creators. Below is the official, objective, and concrete version communicated by LinkedIn.
Links in post text
Adding links inside post text, as long as the content is relevant to your activity and usual posts, does not lower reach.
Diversify your formats
Using diversified content — carousel, photo, video, newsletter — helps the algorithm learn your profile and increases your reach.
Video with descriptive text
Videos perform well when accompanied by reference text that helps the algorithm understand the topic being discussed.
Tag walls: avoid them
Tagging a few relevant people is acceptable. Tagging dozens of people to generate artificial engagement does not work and is penalized.
Hashtags: not decisive
Hashtags mainly help the author find their own content. They are not a decisive factor for reach on the platform.
Luca Gerini's observations
The following are subjective observations based on my direct experience. These are not official LinkedIn data but perceptions developed through consistent posting on the platform.
“Links in posts lower reach, for any post. It probably depends on the landing page or specific factors of my profile.”
“Among all formats, the two that perform best are: plain text (even without images) and PDF carousel.”
“Videos used to perform very well, today they're mediocre compared to carousels and plain text. I keep making them because I believe in the vertical format, but right now they underperform.”
“I completely agree: tag walls are useless.”
“Confirmed: hashtags are useless and quite annoying.”
The rule that never changes
“You must generate content that is useful for your community, useful for the people who read you, useful for the people who visit your profile. If content utility is missing, everything else can go in the trunk and you can go on vacation.”

Frequently asked questions about the LinkedIn algorithm
Quick answers about PostValidator, the LinkedIn 2026 algorithm and pricing.
What is PostValidator?
PostValidator is a SaaS platform that analyzes LinkedIn and Facebook posts before publishing, providing a predictive score based on the LinkedIn 360Brew 2026 algorithm and Meta Algorithm 2026. Developed by Luca Gerini, a LinkedIn creator who grew from 15,000 to 38,000 followers organically in 5 months with zero ad spend.
How does the LinkedIn algorithm work in 2026?
According to LinkedIn Italia (Milan creator event 2026): links in text don't penalize if content is relevant; format diversification increases reach; videos work better with descriptive text; tag walls are penalized; hashtags are not decisive. PostValidator analyzes posts on 8 criteria: hook, dwell time, save-worthiness, comment trigger, format, topic consistency, AI detection risk and golden hour readiness.
Do links in LinkedIn posts lower reach?
LinkedIn officially states that links in text don't lower reach if the content is relevant to your activity. However, practical experience from many creators indicates that posts with links tend to perform worse. PostValidator evaluates this factor in the Format & Media criterion.
Which formats work best on LinkedIn in 2026?
Based on 360Brew 2026 data: 1. Plain text without images 2. PDF Carousel (5.85% engagement rate) 3. Multi-image (6.60% engagement rate) 4. Native video with descriptive text (5.60%). Standalone videos perform worse compared to previous years.
What is the Golden Hour on LinkedIn?
The Golden Hour is the first hour after publishing a LinkedIn post. Comments and interactions received in this window determine whether the algorithm amplifies or limits content distribution. PostValidator evaluates whether a post is structured to generate immediate interactions.
How does PostValidator pricing work?
PostValidator offers 3 free analyses and 2 free rewrites with no account required. To continue: 10 tokens for €14 (1 token = €1.40). Full analysis = 1 token (€1.40). Analysis + rewrite = 2 tokens (€2.80). No subscription, tokens never expire.
Does PostValidator work for Facebook too?
Yes. PostValidator analyzes posts for LinkedIn (360Brew 2026) and Facebook (Meta Algorithm 2026). For Facebook it evaluates: originality, hook, conversation potential, format, shareability, emotional resonance, topic consistency and Golden Hour. Same pricing for both platforms.
What is AI detection risk?
AI Detection Risk measures how much a post seems AI-generated. Posts likely generated by AI receive 45% less engagement (source: Originality.ai, 9,000 posts analyzed). PostValidator analyzes signals like em dashes, overly parallel structures and generic phrases to evaluate perceived authenticity.
What is the best time to post on LinkedIn?
Based on 360Brew 2026 data: Monday-Thursday between 10am and noon. Wednesday is the highest engagement day. Late afternoon (5-8pm) is performing better thanks to mobile usage. PostValidator suggests the optimal day and time for each analyzed post.
Who created PostValidator?
PostValidator was created by Luca Gerini, entrepreneur and LinkedIn creator with 20+ years of international experience. He grew his LinkedIn profile from 15,000 to 38,000 followers in 5 months with zero ad spend. He participated in major exits: Pixmania (€244 million) and Louvre Hotels Group ($2.5 billion). He is co-founder of JobDo.it.
