Paste any call to action, get a 0-100 strength score, the exact levers that drive it, and three sharper rewrites in your brand voice.
TL;DR. A high-converting CTA is 2-5 words, leads with an action verb, names a benefit not a feature, and is the only primary action in the email. "Read this week's report" beats "Click here." "Claim your invite" beats "Submit." The analyzer scores these dimensions plus button vs. link, placement, and contrast.
Each factor contributes to a single 0-100 score with a transparent breakdown.
Action verbs (Get, Start, Claim, Read, Build) outperform passive words (Submit, Click here, Learn more).
2-5 words wins for buttons; 6-10 for inline anchor links.
Names the reader's win, not yours. "Save 30 minutes" beats "Open dashboard."
Concrete nouns ("the 12-page report") outperform vague ones ("more").
Bulletproof button vs. inline link, contrast, position above-the-fold.
Only one primary CTA per send. Competing CTAs each lose ~30% of their click share.
| CTA | Score | Why |
|---|---|---|
| Click here | 22 | No verb specificity, no benefit, generic. |
| Submit form | 34 | Action verb but feature-led; tells the reader what they do, not what they get. |
| Learn more | 41 | Common but vague; works only when the surrounding copy already named the benefit. |
| Read this week's report | 78 | Specific noun, concrete cadence, benefit implied. |
| Claim your invite | 84 | Strong action verb, possessive framing, scarcity hint. |
| Save 30 minutes today | 89 | Quantified benefit, immediacy, no jargon. |
