Hook — does the headline stop the scroll and create an immediate reason to keep reading?
Clarity — is the value proposition immediately obvious without industry jargon?
CTA Strength — is the call to action specific, low-friction, and matched to your buyer's stage?
Urgency/Desire — does the copy create enough pull to make someone act now rather than later?

Why Ad Copy Quality Determines Your CAC
Most paid ad spend is wasted on copy problems, not targeting problems. You can have the right audience, the right bidding strategy, and the right budget — and still get a 0.5% click-through rate because your headline doesn't connect with what your ICP actually cares about.
The gap between average and great ad copy typically comes down to three failures:
The hook is generic — it could be anyone's ad, so it reads as background noise and gets scrolled past
The value proposition is unclear — the buyer can't immediately answer "what's in it for me?" without thinking
The CTA creates friction — asking for a demo or a call on a cold ad matches a commitment level the buyer isn't ready for
Fixing these issues before you launch — not after you've spent $5,000 — is exactly what this analyzer is built for. You get the same feedback a performance marketing director would give in a copy review, instantly, for free.
What Makes Ad Copy Convert Across Channels
While the format constraints differ between Google Ads, Meta, and LinkedIn, the fundamentals of what makes copy convert are consistent across all paid channels. The hook must earn attention in a crowded feed. The body must connect the product's value to the buyer's specific situation. The CTA must ask for exactly the right level of commitment for where the buyer is in their awareness journey.
On Google Search, where buyers are actively looking, the headline needs to match their search intent and promise a specific outcome. On Meta and LinkedIn, where buyers are passively scrolling, the hook carries more weight — it must interrupt the scroll before any selling can happen. This analyzer evaluates your copy against all five core dimensions regardless of which channel you're running on.
Frequently Asked Questions
Ad copy converts when the hook immediately grabs the right buyer's attention, the message connects to a pain they're actively experiencing, the value is instantly clear without jargon, and the CTA matches the commitment level they're ready for. This analyzer evaluates all five dimensions before you spend a dollar on distribution.
A high-converting headline either names a specific pain your ICP is feeling, promises a concrete outcome they want, or challenges an assumption they hold. It avoids generic superlatives like "best" or "leading" and instead uses specific, concrete language. The best headlines make the right person feel immediately seen — and make them want to know more.
Average click-to-conversion rates vary by channel: Google Search averages 3–5%, Meta cold audiences 1–3%, LinkedIn 0.5–2%. But benchmarks are less useful than your own improvement curve. The biggest lever is message-market fit — whether your copy speaks to the specific pain your ICP is feeling. Strong copy can outperform average benchmarks by 3–5x on the same targeting and budget.
