Twitter Analytics Free — Tweet Analyzer & Virality Score Tool

Frequently Asked Questions

What does the tweet analyzer score?

The tweet analyzer scores your tweet across six dimensions: hook strength, engagement words, length, readability, specificity, and call to action. Each category is weighted based on what the X algorithm and real audiences respond to. The final score is out of 100 and maps to a letter grade from A (viral potential) down to F (needs significant rework).

What makes a tweet go viral on X?

Viral tweets typically share a few common traits: a strong opening line that stops the scroll, concrete numbers or specifics rather than vague claims, a clear call to action that invites replies or retweets, and optimal length (usually 70-180 characters for single tweets, or a well-structured thread). Engagement in the first 30-60 minutes also signals to the X algorithm that a tweet is worth amplifying, so timing and audience targeting matter too.

How is the hook strength score calculated?

Hook strength measures whether your first line would stop someone mid-scroll. The analyzer looks for patterns common in high-performing tweets: questions, bold claims, surprising numbers, contrarian takes, and direct calls to curiosity. A weak hook — starting with "I think" or a generic observation — scores low regardless of how good the rest of the tweet is. Your first 10 words are the most important.

What is the ideal tweet length?

For standalone tweets, 71-180 characters tends to perform best — long enough to convey a complete thought, short enough to read in a single glance. Tweets under 70 characters often lack context and tweets over 240 characters can lose readers before the payoff. For thread openers, the hook tweet can be slightly longer since the goal is to tease the rest of the thread.

Why does specificity matter in tweets?

Specific claims outperform vague ones consistently. "I grew from 0 to 4,200 followers in 90 days" is more credible and shareable than "I grew my Twitter following fast." Numbers, timeframes, dollar amounts, and named frameworks signal that you have real experience — which earns trust and makes tweets worth sharing. The specificity score rewards concrete details and penalizes generic language.
