Is LinkPost at €99/month more expensive than SocialSonic?

Yes. SocialSonic Pro starts at $20/month ($13.33 yearly), significantly cheaper than LinkPost. But the two tools don't attack virality at the same level: SocialSonic scores industry trends, LinkPost scores your specific post before publication. If your editorial model is to surf trends, SocialSonic is the right ratio. If you publish to drive business through content and every post has to perform, LinkPost's ROI is measurable (x1.93 likes over 60 days).

SocialSonic scores viral potential, LinkPost too: isn't that the same?

No. SocialSonic scores the viral potential of an industry TREND (a growing topic in your niche). LinkPost scores the viral potential of a specific POST you're about to publish, on 300+ factors including 27 learned on your personal style. Two different analysis levels. SocialSonic says "this topic will explode". LinkPost says "your version 17 of this topic has 73% chance of taking off, your version 3 only 12%". The difference between macro (trends) and micro (your post).

Isn't the 300+ factor scoring just marketing?

No. The V2 algorithm analyzes 300+ factors total, including 27 personalized on your history (vs 49 factors and 0 personal in V1). It's trained on 1M+ LinkedIn posts. Before/after measured results on the 20 most active users over 60 days: x1.93 likes on average, average best post goes from 78 to 237 likes (×3), 1 user out of 4 multiplies their record by 10+. Not marketing, measured numbers.

SocialSonic has a 7-day free trial, LinkPost doesn't?

Correct. SocialSonic offers a 7-day free trial (no credit card required). LinkPost doesn't have a full-product trial, but the Post Analyzer is free without signup at linkpost.gg/post-analyzer: paste a post, we score it on 300+ factors. To use LinkPost in full, sign up then pick a plan: €99/month or €790/year.

Can I migrate my SocialSonic posts to LinkPost?

Nothing to migrate. LinkPost connects to your official LinkedIn account and analyzes your existing posts directly. No copy-paste, no manual import. Your writing profiles are automatically created from your last 100 published posts on LinkedIn.

Is SocialSonic French? And LinkPost?

SocialSonic is a Writesonic product, team mainly based in the US and India (Writesonic is an international AI content company). LinkPost is co-founded by Yannis Haismann in France (alongside LinkHub, LinkEarn and LinkMagnet in the same galaxy). Both are GDPR-compliant. Both publish via the official LinkedIn API.

[Breakdown · Feature by feature]

Feature-by-feature breakdown

Post-level prediction vs trend detection

This is the structural gap between the two tools. SocialSonic bets on TRENDS: their AI detects growing topics in your niche and assigns them a viral potential score, so you surf the wave before it passes. It's their core product. LinkPost bets on prediction at the POST level: before you click Publish, the algorithm analyzes your post on 300+ factors, including 27 learned on your past posts (length, hook structure, question density, CTA types, emoji frequency). Not market averages. Your stats. Your patterns. Your best hooks. Trained on 1M+ LinkedIn posts and aligned with LinkedIn Engineering's public research (March 2026). SocialSonic = trend scoring. LinkPost = your post scoring.

LinkPost wins

Two valid approaches, but LinkPost covers prediction where it matters most: your specific post before publication.

25-variant generation + scoring + best-pick

SocialSonic generates content on a detected trend — 1 post at a time, calibrated on your voice. If you want a variant, you re-run. LinkPost works differently: you give an idea, we generate 25 variants calibrated on different angles (storytelling, controversy, data, expertise, punchy hook, emotional opener). Each variant is then scored on 300+ factors. You see immediately which one has the highest probability of taking off. You publish that one. The difference between "generate a post on a trend" and "see 25 versions of your idea scored and be told which to publish".

LinkPost wins

25 scored variants vs 1 post at a time. LinkPost wins on scientific multi-angle creation.

Real-time LinkedIn trend discovery

This is the ground where SocialSonic wins outright, and we have to be honest. Their product is calibrated to identify emerging topics in your niche in near-real-time, with a numerical viral potential score for each trend. You get alerts and can generate a post directly on the trend. Useful if your editorial model relies on reactivity to trends. LinkPost integrates industry news via the AI Strategist to build your monthly plan, but it's not the core of the product. On pure trend detection, SocialSonic is better calibrated.

SocialSonic wins

SocialSonic wins on real-time trend detection — that's their core product.

Analytics: LinkPost covers all SocialSonic + goes deeper

SocialSonic offers "rich insights that show what drives real growth": post performance, network growth, classic metrics. Solid. LinkPost covers 100% of those analytics, then goes several levels further: business funnel mix (TOFU/MOFU/BOFU) per post, analysis of 100% of comments (sentiment, controversy, your audience's emotional response), identification of your real best post (1 user out of 3 discovers it's not what they thought), niche benchmark, emotional prediction BEFORE publication. The same depth applies to any LinkedIn creator via Spy Mode. SocialSonic = growth analytics. LinkPost = behavioral science.

LinkPost wins

LinkPost captures everything SocialSonic measures, then goes deeper: sentiment, TOFU/MOFU/BOFU, emotional prediction.

Competitor Spy Mode

SocialSonic offers "thought leader discovery": identify opinion leaders in your niche and observe their content. Useful for inspiration. LinkPost does active decomposed monitoring: you pick a LinkedIn creator in your niche, we monitor them non-stop and surface their real controversy level, TOFU/MOFU/BOFU mix, most profitable topics, viral tactics, audience emotional response per post, best publishing days, whether they're in a POD, and the top 10 most engaged profiles around them. You don't just learn that a creator is crushing it. You learn WHY they're crushing it.

LinkPost wins

SocialSonic identifies leaders. LinkPost decodes their full strategy.

AI Strategist: 1 month of content in 2 clicks

SocialSonic offers "personalized content ideas" based on detected trends — useful but stays at piece-by-piece suggestions. LinkPost goes several levels further: you ask for your monthly editorial plan, the AI Strategist runs hundreds of parallel queries on its 1M+ post database, your personal history, and real-time industry news. Output: 30 posts built on what actually works in your niche, internally coherent, ready to publish. 1 post idea per day, a full month of structured editorial, in 2 clicks.

LinkPost wins

SocialSonic = trend-based ideas. LinkPost = monthly editorial plan built with live data + your stats.

Hooks and 33 measured tactics

SocialSonic optimizes your voice via its AI Content Creation. Solid for staying consistent in your style. LinkPost goes several levels further: 33 measured virality tactics (22 attention tactics + 11 rules), organized in 7 categories (Attention, Rhythm, Engagement, Emotion, Credibility, Cognition, Distribution). For each tactic: examples from real high-performing LinkedIn posts, YOUR personal stats (how many of your posts use this tactic, your average likes with vs without), and the measured impact on your performance. The X-Ray mode in the editor points directly to each missed tactic while you write. Full public documentation: linkpost.gg/cheat-sheet.

LinkPost wins

SocialSonic = voice optimization. LinkPost = 33 measured tactics with personal stats and direct editor integration.

Multi-account and agency collaboration

SocialSonic explicitly positions multi-level: Team Accelerator (3 users, $75/month) with company page management and approval workflows, Agency Powerhouse (10 users, $200/month) with multi-client analytics, custom branding and sentiment analysis. Team and Agency plans are announced Coming Soon. LinkPost integrates multiple writing profiles + unified calendar, but stays focused on content creation (not multi-client agency management at scale). If your model is managing 5-20 accounts with client workflows, SocialSonic Team/Agency is better calibrated long-term.

SocialSonic wins

SocialSonic wins on multi-client agency collaboration (Team + Agency plans). LinkPost fits 1-5 accounts.

If your editorial model is to react fast to your industry trends (news, new tools, hot debates), SocialSonic is the better-calibrated tool. Real-time trend discovery + viral potential scores + generation on those trends. You surf the waves before they pass. LinkPost integrates news via the AI Strategist but it's not its core product.

B2B SaaS founder generating leads from content

A single viral post can bring you 5 to 15 demo requests. You don't have time to publish on a trend hoping it takes off for you. LinkPost generates 25 scored variants at the post level, tells you which to publish before you click, and learns your style. Over 90 days, the ROI of a single successful post pays for 6 months of subscription at €99/month.

Recommendation[LinkPost]

Solopreneur or freelancer with only 30 minutes a day for LinkedIn

You publish to drive business but you don't have 2 hours a day to scroll trends or iterate on your post. LinkPost generates 25 variants in a few minutes, scored on 300+ factors, and tells you which to publish (the best-scored one). 20 minutes flat for a post calibrated on the science of virality. SocialSonic asks you to surf trends — that's a more time-expensive editorial mode.

[Our verdict · Which one, really]

Final verdict

[Our pick · For LinkPost]

SocialSonic has a 7-day free trial, LinkPost doesn't?

[METHODOLOGY]Cohort: the 20 most active LinkPost users (measured by post volume) during the beta period, before the official public launch. No cherry-picking: top 20 by activity, not by results. For each user, we compare their average likes and record posts over the 60 days before they signed up to LinkPost vs the 60 days after signup. Identities anonymized (LP-001 to LP-020).

Does LinkPost also detect my industry trends?

Yes, via the AI Strategist: when you request your monthly editorial plan, the tool integrates real-time industry news to build 30 coherent and calibrated posts. But trend detection isn't LinkPost's core — it's one brick in a larger stack (post prediction + 25 scored variants + Spy Mode + 33 tactics + analytics). On pure instant trend detection, SocialSonic is better calibrated.

Should I leave SocialSonic to switch to LinkPost?

Depends on your usage. If you use SocialSonic mainly for real-time trend detection and gamification, keep SocialSonic — LinkPost covers industry news but it's not its core. If you use SocialSonic mainly for generation + scheduling, LinkPost clearly replaces it with virality prediction, 25-variant scoring, Spy Mode and AI Strategist. The two can also coexist: SocialSonic to detect trends, LinkPost to score and publish the right post on them.

How does LinkPost factor in the new LinkedIn algorithm?

LinkPost's virality prediction algorithm was designed building on LinkedIn Engineering's public research, notably the article "Engineering the next generation of LinkedIn's Feed" published by Hristo Danchev on March 12, 2026 (https://www.linkedin.com/blog/engineering/feed/engineering-the-next-generation-of-linkedins-feed). That paper details the transition to a unified feed via LLM embeddings, percentile bucketing of engagement signals (popularity-signal correlation ×30 per LinkedIn), temporal interaction sequences (Generative Recommender, transformer with causal attention), and the passive/active signal distinction. Our algorithm models exactly these signals: estimated dwell, passive/active mix, semantic structure, persona-specific temporal profile. That's what sets it apart from a plain LLM-as-a-judge based on grammar.
