Publishing & Growth Tools

Eight tools you use between exporting and hitting publish: thumbnail scoring, posting times, A/B test sizing, hashtag checks.

First-Frame Impact Score

Score your cover / thumbnail across 4 documented behavioral dimensions: face visibility, contrast, text load, hook pattern.

How to interpret

A 4-dimension heuristic. Each dimension is what marketing-creative literature cites as a stop-scroll lever - not a CTR prediction. Use it to spot which dimension is dragging the frame down.

Engagement Rate Tier Classifier

Likes + comments + shares + saves ÷ views. Tier it against platform ranges.

How to interpret

ER thresholds vary wildly by niche, follower count and platform. The "Above average" tier here is a rough industry mid-band; small accounts typically see inflated ER.

Watch Time Required Estimator

Estimate the per-day watch-time needed for algorithmic lift at your subscriber/view level.

How to interpret

Public platform engineering posts and creator-economy surveys point to "watch minutes per day ÷ audience" as one of the most predictive inputs for For You / Recommended ranking. These are starting hypotheses, not official numbers.

Posting Time Heatmap

See a typical week-by-hour posting heatmap for each platform. Generic baseline; always validate against your own analytics.

How to interpret

Darker = historically higher co-viewer activity. Times shown are local-to-your-browser. Many creators see a flat curve from 5-9 PM any weekday; the second-best slot after your top one is usually enough.

A/B Test Sample Size

How many impressions per variant do you need for a meaningful A/B test?

In percent (e.g. 3.5 for 3.5%).
Absolute percentage points (e.g. +1 → 4.5%).
How to interpret

A reliable test needs ~weeks of data; chasing tiny effects (under 0.5 percentage points) is rarely worth the time. Most short-form thumbnail tests converge by 5-10 days at moderate impressions.

Caption SEO Density Checker

How heavily does your caption lean on a chosen keyword? With over-optimization warning.

How to interpret

A natural mention is 1-2 uses per 100 words. Stuffing the same phrase 4+ times looks spammy and may reduce reach. "Stuff" tags put all your SEO weight at the end of the caption - usually after the fold.

Retargeting Audience Size Estimator

Estimate addressable retargeting audience from your organic video performance.

Industry varies. E-com: 1-3%. Lead-gen: 0.5-1%.
How to interpret

All ads are estimates. The platform's ad manager will give exact reach for a given bid. Use this calculator as a "should I even bother running an ad on this scale" sanity check.

Caption Background Effectiveness

Three common caption backgrounds compared (drop shadow, plate, blurred plate). We rank them for visual clarity, accessibility, and platform fit.

How to interpret

The "best" background depends on your subject content. The visual weight rises with plate opacity which can compete with the subject. We rank only contrast safety.

Sponsored placement

One calm ad slot between tools. No popups, no autoplay, no overlay panels.
