How it works

Three steps from upload to actionable Feed-specific insights.

1

Upload your Facebook ad

PNG, JPG, or WebP. 1:1 or 4:5 recommended for Feed — we score against the actual Meta placement.

2

See it in the Meta Feed

Your creative renders in a realistic mobile Feed mockup with profile header, copy, and engagement bar.

3

Get the heatmap + fixes

Attention overlay, scroll-stop score, CTA visibility, 20% text-rule check, and specific fixes — in under 8 seconds.

Six checks before you spend

Meta Feed has its own attention rules — mobile-first, thumb-scroll, heavy competition with organic content. We check the six factors that separate scaling creatives from the ones Meta delivers into a trickle.

Scroll-stop strength

Whether your creative interrupts the Feed scroll in the first 1.5 seconds. Driven by contrast, motion, and first-frame salience.

CTA visibility in Feed context

Mobile Feed has a specific thumb-stop zone. CTAs outside that vertical band lose 40–60% of potential clicks.

20% text rule + safe zone

Meta de-prioritizes heavy-text creatives. We compute text coverage and flag safe-zone violations before you submit.

Mobile legibility at 375px

80%+ of Facebook impressions are mobile. We verify headline legibility and minimum font sizes at actual mobile viewport width.

Brand recall positioning

Logo placement and visibility — top-left logos average 2.3× better recall than bottom-right placements in Feed.

First-frame impact score

The frame a viewer sees in 1.5 seconds. Determines whether the ad earns a second look or gets scrolled past.

Why Meta Feed is different

Why Facebook ads need their own attention audit

Meta Feed is the most competitive attention environment in digital advertising. The average user scrolls through 300+ feet of content per day across Facebook and Instagram, and your ad has to fight for attention against friends' photos, reels, news, and organic brand posts — not just other ads. An analyzer that doesn't model Feed context will miss the failure modes specific to that placement.

Three things make Meta Feed attention distinct from display or search. First, the Feed scrolls vertically on mobile — viewers scan top-to-bottom in a narrow thumb-width column, with most fixations concentrated in the upper 60% of each post. CTAs placed below this line lose disproportionate visibility. Second, viewers decide to stop or scroll in 1.5 seconds, meaning the first-frame impact matters more than any copy or headline that loads later. Third, Meta's delivery system actively throttles certain creative patterns — heavy text coverage, low visual diversity, and creatives that don't drive engagement see quieter delivery curves.

The economic impact of these Feed-specific patterns is substantial. In aggregate data from 2,400+ Meta campaigns, creatives scoring above 75 on our Meta Feed attention score delivered an average CTR of 1.6% — nearly double the 0.9% CTR of creatives scoring below 60. That CTR delta compounds across the funnel: lower CPM (Meta rewards higher engagement with cheaper delivery), lower CPC, lower CPA, and higher ROAS. Getting Feed-specific creative right is the highest-leverage move in the Meta playbook.

What to verify before every Meta Feed launch: (1) scroll-stop strength — is the first frame disruptive enough to pause the thumb? (2)CTA in the upper-60% thumb-stop zone, not the lower-right periphery. (3)text coverage below 25% of the image area. (4) Mobile headline legibility at 375px — legibility is non-negotiable since that's the viewport 80% of viewers will use. A Facebook ad analyzer that measures these four in under 10 seconds is the single biggest pre-launch productivity upgrade for any Meta-heavy creative team.

Frequently asked questions

What does a Facebook ad analyzer check?

A good Facebook ad analyzer verifies four things: (1) scroll-stop strength — whether the creative interrupts the Feed scroll in the first 1.5 seconds, (2) CTA visibility within the Feed's mobile gaze pattern, (3) compliance with Meta's 20% text rule and safe-zone guidelines, and (4) mobile legibility at 375px viewport width. GazeIQ runs all four plus produces an overall Meta Feed attention score.

What is the 20% text rule and does it still apply in 2026?

Meta's historical 20% text rule limited how much of an ad image could be covered by overlaid text before the platform would deprioritize delivery. In 2020 Meta softened the hard cap, but the underlying signal still influences delivery — heavy-text creatives (35%+ coverage) typically see 20–40% lower CPM efficiency than lighter-text creatives. The rule is no longer enforced as a hard block, but it remains a best practice.

How is this different from Meta Ads Manager's preview?

Meta Ads Manager shows you what your ad will look like in placement — a static preview. A Facebook ad analyzer goes further by predicting where viewers' eyes will land, scoring CTA visibility, checking text density and safe-zone compliance, and comparing against benchmark creatives for similar placements. Ads Manager shows the ad. GazeIQ predicts the performance.

What Facebook ad sizes are supported?

The analyzer supports every standard Facebook placement: Feed 1:1, Feed 4:5 (the highest-performing aspect ratio for mobile), Story 9:16, Reels 9:16, Marketplace, and Messenger. Each placement is scored against its own attention pattern — a creative optimized for Feed has a different scoring profile than the same creative running as a Story.

Can I analyze my Facebook ads without a Meta account?

Yes. You don't need to connect Meta Ads Manager or have an active ad account. Just upload your creative image and GazeIQ will score it in a simulated Meta Feed mobile context. For advanced workflows like pulling live creatives directly from your Ads Manager, Pro and Agency plans include a Meta integration.
