Lead Magnet Copy Grader
Grade how compelling your lead magnet really is before you promote it.
Few people trade an email for this. Vague promises and heavy PDFs read as low value. Pick one specific outcome your ICP wants now and deliver it in the lightest possible format.
Perceived value is set before download, specificity and format do most of the work. A great asset with a weak promise still won't get the opt-in.
About this calculator
An email address is a real cost to a visitor, so the offer trading for it has to feel worth it before they'll ever open the download. This grader scores your lead magnet on five factors, promise specificity, speed of value, format appeal, credibility, and ICP relevance, so you know whether it earns the opt-in or just sits there getting ignored.
How to use it
- Rate your lead magnet on five factors as Strong / Somewhat / Weak: promises a specific, tangible outcome; delivers value fast rather than requiring a long read; has an appealing format (tool or template beats a generic PDF); feels credible enough to be worth an email; and is directly relevant to your ICP's actual problem.
- Read the weighted score and verdict.
- If the score is average or below, start with promise specificity and format, they carry the most combined weight and the fastest wins.
Methodology
Each factor is scored Strong=full, Somewhat=half, Weak=zero, multiplied by its weight: specific/tangible promise 25, ICP relevance 25, speed of value 20, format appeal 15, and credibility 15. Weighted points sum to a 0-100 score.
Scores of 78+ are graded "High-converting," 50-77 "Average," and below 50 "Low-value, skip-worthy," reflecting how much friction the offer itself creates against the (unavoidable) friction of handing over an email address.
This is a self-graded structural check on your offer's composition, not a measured opt-in conversion rate. It scores the offer before download; actual opt-in rate also depends on the surrounding page, form length, and traffic quality.
FAQ
A lead magnet only converts if the exact person it's aimed at recognizes their own problem in the promise, generic offers ("our ultimate guide to marketing") fail on relevance even when the content inside is genuinely good, because nobody feels personally addressed by them.
Not automatically, but interactive formats (calculators, templates, checklists you can use immediately) tend to signal and deliver faster value than a long-form PDF, which reads as more effort to consume. If a PDF is genuinely the best format for your content, keep it short and scannable to offset the format penalty.
No, it tells you the offer itself is well-constructed. Opt-in rate is also shaped by the surrounding landing page, how many form fields you ask for, and whether the traffic arriving actually matches the ICP the magnet was built for.
