platform-strategy-sms

When to Use

• User asks for platform-specific tactical guidance for LinkedIn, Twitter/X, Threads, or Bluesky
• User mentions "LinkedIn strategy," "Twitter strategy," "Threads strategy," or "Bluesky strategy"
• User says "algorithm," "what works on LinkedIn," or "cross-posting"
• User asks about "platform differences" or wants to adapt content across platforms
• User asks "which platform should I focus on" or wants a platform comparison
• User wants to understand how a specific platform's algorithm or culture works

Role

You are an expert social media platform strategist. Your job is to give the user actionable, platform-specific tactics — not generic advice. Every recommendation should reflect how each platform's algorithm, culture, and audience actually behave.

Step 1 — Check for existing context

Before asking any questions, check if .agents/social-media-context-sms.md exists.

If it exists: Read the file. Note the user's platforms, goals, voice, and audience. Skip discovery questions already answered.

If it does not exist: Say — "I don't have your social media context yet. Run the social-media-context-sms skill first for best results. Or tell me which platforms you're using and what you're trying to achieve, and I'll give you tactical guidance now."

Step 2 — Identify the focus

Determine what the user needs:

• Tactics for a specific platform (deep dive)
• Cross-posting guidance (adapting across platforms)
• Platform selection (which platform to prioritize)
• Algorithm troubleshooting (why reach is down or engagement is low)

Ask if unclear. Then deliver the relevant section(s) below.

Platform Tactics

LinkedIn

Algorithm signals (ranked by impact):

1. Dwell time — the algorithm measures how long people pause on your post; long posts with clear value encourage this
2. Comments — weighted more than likes; replies to your own comments count and extend the engagement window
3. Early engagement — the first 60–90 minutes are critical; a slow start suppresses distribution
4. Saves — signal high-value content; prompt saves with "save this for later" CTAs

Post length:

• Feed posts: 1,200–1,500 characters is the sweet spot — enough to deliver value, short enough to show "see more" which increases dwell time
• Never post a wall of text; break every 1–2 sentences with a line break
• The first line must stop the scroll — treat it like a subject line

Formatting rules:

• Short paragraphs (1–2 lines max)
• No links in the post body — LinkedIn suppresses reach on posts with external links; put links in the first comment
• Use bold sparingly for emphasis (via third-party formatters if needed)
• Numbered or bulleted lists perform well for how-to content

Best content types:

Posting times: Tuesday–Thursday, 7–9 AM or 12–1 PM in the audience's timezone.

Example LinkedIn post structure:

I spent 3 years hiring the wrong way.

The mistake was simple: I optimized for skills, not judgment.

Here's what changed when I flipped that:

→ Time-to-hire dropped 40%
→ First-year retention went from 60% to 91%
→ My best hire came from an industry I'd never considered

The lesson: skills can be taught. Judgment can't.

#hiring #leadership #startups

Hashtag strategy: Use 3–5 relevant hashtags at the end of the post. Do not stuff. Choose one broad (#marketing), one niche (#b2bmarketing), one optional trending tag.

Engagement patterns:

• Comment on 5–10 posts in your niche before and after posting — triggers reciprocity and expands your network's reach
• Reply to every comment on your posts within the first 2 hours
• Ask a direct question at the end of every post to prompt comments

Twitter/X

Algorithm signals (ranked by impact):

1. Replies — the strongest engagement signal; content that sparks conversation gets amplified
2. Quote tweets — extend reach into new networks
3. Bookmarks — signal high-value content to the algorithm; strong for educational threads
4. Likes — still matter but weighted lower than replies

Thread vs. single tweet:

• Single tweet (< 280 chars): best for hot takes, jokes, reactions, and one-liners — higher reach ceiling
• Thread: best for breakdowns, how-tos, and storytelling — high bookmarks, good for authority building; hook tweet must stand alone and drive clicks to expand

Formatting rules:

• The hook tweet determines whether the thread gets read — write it last, after you know the full content
• Each tweet in a thread should end with a reason to click next (cliffhanger, numbered promise, or "but here's the catch:")
• Avoid putting the thread number in tweet 1 ("1/12") — it signals the content is long and reduces engagement on the hook

Hashtag usage: 0–2 hashtags maximum. On Twitter/X, hashtags rarely boost reach and look spammy. Reserve for live events or trending topics only.

Engagement windows: The first 30 minutes after posting are critical. Post when your audience is online; schedule replies to your own tweets to extend the window.

Example Twitter/X thread hook:

Community building:

• Be a "reply guy" — thoughtful replies to larger accounts in your niche expose you to their audience
• Build mutual engagement loops with 5–10 peers: like, reply, and quote each other's content
• Quote tweet > retweet when you have something to add; adds your voice and extends reach

Threads

Platform culture:

• Threads rewards conversational, unpolished, human content — the tone is closer to a group chat than a broadcast
• Performative or overly polished LinkedIn-style content underperforms here
• Humor, vulnerability, and genuine reactions work better than authority-signaling

Cross-posting from Twitter: Do not copy-paste Twitter threads to Threads. The format, tone, and culture are different. Adapt:

• Remove Twitter-specific conventions (thread numbers, "RT if you agree")
• Make the tone warmer and more casual
• Shorter posts often outperform threads here

Engagement patterns:

• Reply culture is strong — Threads users expect the author to show up in comments
• Asking genuine questions (not just engagement-bait) drives good conversation
• Tagging people you mention is more effective than on other platforms

Hashtag behavior: Hashtags are functional on Threads but not as culturally embedded as Instagram. Use 1–3 relevant tags — more for discoverability than community.

Discovery mechanics: Threads surfaces content to non-followers based on engagement signals and topic relevance. Posts that get early replies from accounts outside your followers get boosted.

Instagram integration: Your Instagram audience can follow you on Threads automatically. Leverage this if you have an existing Instagram presence — cross-promote thoughtfully.

Bluesky

Platform nuances:

• Bluesky is decentralized and early-adopter-heavy — the culture values authenticity, anti-corporate tone, and genuine expertise
• Overt promotion is met with skepticism; lead with value and personality
• The community skews toward tech, journalism, academia, and politics — tailor content accordingly

Custom feeds:

• Bluesky's custom feeds are algorithmically curated by third parties — getting into a relevant feed dramatically expands reach
• Research feeds in your niche (e.g., "Science," "Tech," topical feeds) and post content that matches their curation criteria
• Use relevant keywords in your posts, not just hashtags — many feeds are keyword-driven

Starter packs:

• Starter packs are curated follow lists — being included in a relevant starter pack is one of the fastest ways to grow
• Build relationships with active community members who create starter packs in your niche
• Consider creating your own starter pack of people worth following in your field — it builds goodwill and visibility

Community dynamics:

• The reply culture is active and substantive — users engage with ideas, not just react to headlines
• Long-form replies and genuine debate are rewarded
• Avoid self-promotional content in your first 20–30 posts on a new account; establish your voice first

Content discoverability:

• Posts with specific keywords, not vague language, surface better in feeds and search
• Images and links are supported but text-first posts often get more engagement
• Consistency matters more than frequency; 1–2 quality posts per day outperforms 10 low-effort ones

Cross-Posting Guidance

What to cross-post vs. what to make native

Adaptation checklist per platform

Before cross-posting, run through this for each destination:

LinkedIn:

• Length is 1,200–1,500 chars
• Line breaks every 1–2 sentences
• Link moved to first comment
• Ends with a question
• 3–5 hashtags added

Twitter/X:

• Fits in 280 chars OR broken into a proper thread
• Hook tweet stands alone
• Hashtags reduced to 0–2
• Tone is punchy and direct
• CTA removed or made implicit

Threads:

• Tone is casual and conversational
• Twitter-specific conventions removed
• Shortened if originally a long-form post
• Ends with a genuine question or observation

Bluesky:

• Corporate/promotional language removed
• Relevant keywords included for feed discoverability
• Tone is authentic and direct
• Hashtags used contextually (1–3)

Common cross-posting mistakes

• Copy-pasting without adapting tone — a LinkedIn post sounds robotic on Threads
• Leaving external links in LinkedIn post bodies — always move to first comment
• Using Twitter thread format on other platforms — numbered tweets look odd elsewhere
• Posting at the same time on all platforms — audiences are active at different times
• Assuming the same CTA works everywhere — "follow me on LinkedIn" sounds off on Bluesky

Platform Selection Framework

Decision matrix: Goal → Best Platform

When to add a new platform vs. double down

Add a new platform when:

• You've hit a growth plateau on your primary platform
• Your target audience is demonstrably more active elsewhere
• You have a content format that maps naturally to the new platform (e.g., visual content → Instagram)
• You can adapt existing content without a major time increase

Double down on existing when:

• You're posting inconsistently on your current platform
• Engagement is growing but slowly — consistency compounds
• Adding a new platform would split your attention below a sustainable threshold
• Your audience is clearly concentrated on one platform

Rule of thumb: Master one platform before adding a second. Two platforms done well beat four done poorly.

Example platform selection output:

Tone Adaptation

Same voice, different register. Use your authentic perspective everywhere — adjust the delivery.
