Understanding Your Quality Score

Our AI analyzer evaluates 8 key factors to calculate your post quality score from 0-100

📝 Content Quality

25%

Analyzes readability, grammar, emotional tone, and message clarity. High-quality content is concise, error-free, and emotionally engaging.

Best practice: Write in active voice, use power words, and keep sentences under 20 words for maximum readability.

📊 Optimal Length

20%

Checks if your post length matches platform best practices. Too short lacks value; too long loses attention.

Best practice: Instagram: 125-150 chars, Twitter: 71-100 chars, LinkedIn: 1,300+ chars, Facebook: 40-80 chars.

#️⃣ Hashtag Strategy

20%

Evaluates hashtag quantity, relevance, and popularity. Balances reach with targeting specificity.

Best practice: Mix small (<10K), medium (10K-500K), and large (500K+) hashtags. Instagram: 5-10, Twitter: 1-2, LinkedIn: 3-5.

🎯 Call-to-Action

15%

Detects presence and effectiveness of CTAs. Posts with a clear next step tend to drive more clicks and comments.

Best practice: Use action verbs: "Shop now," "Learn more," "Tag a friend," "Save this post," "Share your thoughts."

🖼️ Visual Elements

10%

Checks for media attachments. Posts with images or video consistently outperform text-only posts on every platform.

Best practice: Use high-resolution images (1080x1080px min), videos under 60s, or eye-catching graphics.

⏰ Timing Optimization

10%

Evaluates posting time against platform peak hours. Posting when your audience is active helps maximize initial engagement.

Best practice: Instagram: 11am-1pm & 7-9pm, LinkedIn: Tue-Thu 9-11am, Twitter: 8-10am & 6-9pm.

Frequently Asked Questions

What is a social media post quality checker?+
A social media post quality checker is a tool that analyzes your content before you publish it. It evaluates factors like text length, readability, hashtag usage, call-to-action effectiveness, and media attachments, then gives you a score (0–100) and specific tips to improve. This checker works for Instagram, Facebook, Twitter/X, LinkedIn, and TikTok.
How does the post quality score work?+
The tool evaluates 6 factors: Content Quality (25%), Optimal Length (20%), Hashtag Strategy (20%), Call-to-Action (15%), Visual Elements (10%), and Timing (10%). Each factor is scored based on platform-specific best practices, and the weighted scores are combined into a single 0–100 rating.
What is a good quality score to aim for?+
A score of 70 or above is considered good. Scores of 80+ are excellent. Focus on the specific recommendations the tool gives you rather than chasing a perfect 100 — fixing the flagged issues will have the most impact on your post performance.
Can I use this as a Facebook post checker?+
Yes. Select Facebook as your platform, paste your post, and the tool will analyze it against Facebook-specific best practices — including optimal length (40–80 characters), hashtag count (1–2 max), and CTA effectiveness.
Does it work as an Instagram caption analyzer?+
Yes. When you select Instagram, the tool evaluates your caption length, hashtag count and relevance, emoji usage, call-to-action, and whether you have media attached — all based on what works on Instagram specifically.
How important are hashtags for post quality?+
It depends on the platform. Hashtags are important for discoverability on Instagram (3–5 relevant tags) and TikTok, moderately useful on LinkedIn (1–3 professional tags), and less critical on Facebook (0–2) and Twitter (1–2). Quality and relevance matter more than quantity.
Can I use the same post across all platforms?+
You can reuse the same idea, but each platform has different optimal lengths, hashtag norms, and audience expectations. A LinkedIn post that works at 1,300 characters will not perform the same way on Twitter at 280 characters. Use the platform selector to check your post against each platform separately.
Is this post checker free?+
Yes. The tool is completely free to use with no login, no sign-up, and no usage limits. You can analyze as many posts as you want.
