How It Works
Describe your target audience — their role, context, and what they care about. Choose your campaign objective: Conversions, Lead gen, Traffic, Awareness, or Retargeting. Enter your primary text (up to 500 characters — note that Facebook shows the first ~125 before truncation), headline (up to 40 characters), optional link description (up to 30 characters), CTA button, and ad format. Hit analyze.
Our AI evaluates your ad across five dimensions: scroll-stop power (does your primary text hook them in the first two lines?), ICP targeting fit (does the copy speak to the exact motivations of your described audience?), value clarity (is the benefit obvious without effort?), offer strength (is what you're offering compelling enough to act on?), and CTA alignment (does your button choice and objective match where the audience is in their decision journey?). You get a letter grade, a plain-English summary, and the single most impactful change — free, in seconds.

What You'll Get
Free analysis includes your overall grade (A through D), a one-sentence summary of your ad's main strength and weakness, and the single highest-leverage change you can make before launching.
Full report (free account required) includes:
Scroll-Stop Power score — do the first two lines of your primary text earn the 'See more' tap, or get scrolled past?
ICP Targeting Fit score — does the copy speak to your audience's actual motivations and language?
Value Clarity score — is the benefit immediately obvious, or does the reader have to work to understand it?
Offer Strength score — is what you're asking them to do worth their attention at this stage of awareness?
CTA Alignment score — does the CTA button match your campaign objective and the audience's readiness to act?

Why Facebook Ad Copy Testing Matters Before You Spend
Facebook ad spend is immediate — once you launch, you're paying for every impression whether your copy lands or not. Most advertisers learn what works through trial and error with real budget, accumulating weeks of data before they find a winning creative angle.
This analyzer lets you stress-test your copy before your campaign goes live. The three gaps that sink most Facebook ads:
The primary text opens with what the brand wants to say, not what the audience is thinking when they see it in their feed
The headline tries to be clever instead of being clear — buyers skip ads they have to decode
The CTA button doesn't match the campaign objective or the audience's stage of awareness — asking for a purchase from a cold traffic audience, or using 'Learn More' when the audience is ready to convert
This meta ad copy tester evaluates each of these failure modes against the specific audience and objective you describe — not generic Facebook best practices. Every recommendation is calibrated to what your ICP will actually respond to.
How Numi Scores Your Facebook Ad
Most Facebook ad copy checkers run against readability rules or generic engagement benchmarks. Numi evaluates your ad relative to the specific audience you describe and the objective you select. The same primary text can score very differently for a cold traffic Awareness campaign versus a warm Retargeting campaign — because the audience's state of mind, trust level, and readiness to act are completely different.
The five scoring dimensions are chosen to reflect what actually drives Facebook ad performance:
Scroll-Stop Power — the first ~125 characters of primary text are shown before truncation. If they don't earn the tap, your headline never gets read
ICP Targeting Fit — measures whether your copy speaks to the motivations and vocabulary of the audience you're targeting, not just their demographic
Value Clarity — evaluates whether the benefit is stated in a way a first-time viewer can grasp in under three seconds of skimming
Offer Strength — scores whether what you're asking the audience to do is worth their time given their current awareness level
CTA Alignment — checks whether your CTA button and campaign objective are matched to what the audience is actually ready to do
Frequently Asked Questions
A Facebook ad analyzer evaluates your ad copy — primary text, headline, link description, CTA button, and format — against your stated target audience and campaign objective. It scores five dimensions: scroll-stop power, ICP targeting fit, value clarity, offer strength, and CTA alignment. Unlike generic copy checkers, this analyzer adapts scoring to your specific audience and objective, so a Conversions campaign targeting SaaS buyers gets different feedback than an Awareness campaign targeting DTC shoppers.
Facebook ads that convert share four traits: a primary text opening that stops the scroll in the first two lines, a headline that makes the value obvious in under five words, an offer that speaks to a specific pain or desire the audience has right now, and a CTA that matches what the audience is ready to do at that stage of awareness. Most ads fail because the copy is written from the brand's perspective — what they want to say — rather than what the buyer is thinking when they see the ad.
A good Facebook ad copy checker evaluates your creative against your specific target audience and campaign objective — not just readability scores or generic marketing rules. It should score the opening hook, the headline, the offer clarity, and whether the CTA aligns with the user's stage of awareness. This analyzer does exactly that: it evaluates your full ad brief against the ICP you describe and the objective you select.
Yes. The basic analysis — grade, summary, and one top improvement — is completely free with no signup required.

Yes — format shapes what the audience expects and how they engage. Single image ads rely almost entirely on copy and visual stopping power. Carousel ads work best when each card carries a distinct benefit or product, with copy that sets up the swipe. Video ads have a grace period of 3 seconds to hook the viewer before they scroll. Collection ads are optimized for browsing and discovery, not direct response. This analyzer factors in the format you select and adjusts scoring accordingly — flagging when your copy doesn't match the engagement pattern of your chosen format.
