Why I tested it
I was about to write yet another 12-page audit for yet another e-commerce client when the launch email landed. Audit Engine claimed it could produce client-ready PDFs in under two minutes. I'd heard that pitch before — usually it ends with a one-page bulleted summary that no client would pay for.
I bought the $97 plan, ran it against three sites I already had finished audits for, and compared. Two of the three came back with 80% overlap on my own findings, and one caught something I'd missed. That was enough to keep going.
Two weeks later, I've run 13 audits through it for paying clients. None have asked for a refund. Two have asked for a follow-up engagement. Here's the briefing.
What surprised me
The PDF is genuinely client-ready. It's not a CSV export with a header. It's a 14-page document with cover, exec summary, prioritized findings, before/after screenshots, and a 30-day action plan. Branded with the client's logo if you upload one.
The audit engine itself runs five passes: technical SEO, page speed, mobile UX, on-page SEO, and conversion (CTAs, forms, trust signals). Each pass returns a score plus 2-5 specific findings with screenshot evidence. I checked the technical SEO pass against Screaming Frog and Sitebulb — it caught 87% of the issues both of those caught. That's not "as good," but for $97 vs. their $200/yr licenses, it's enough.
The conversion pass is the differentiator. It looks at button copy, form length, trust badges, and reading level. None of the technical SEO tools do this. Screaming Frog can't tell you your CTA is buried below the fold.
The first time a client said "this is the most useful audit I've ever paid for," I went back and checked which tool wrote it. It was the tool, not me.
— Two-week testing notes
What's working
- 14-page PDF is genuinely client-ready, not a glorified CSV.
- 5 audit passes — technical, speed, mobile, on-page, and conversion.
- White-label — client logo + your brand on the cover.
- ~90 seconds per run. I made coffee in the time it took.
- $97 one-time — not subscription. Compare to Sitebulb at $169/yr.
What isn't
- Caps at 50 pages crawled. Big sites need a real crawler.
- No JavaScript rendering in the technical pass. SPAs get partial coverage.
- UI is rough. Functional, but the dashboard is dense.
- No team accounts in the FE plan. Solo only.
Should you buy it?
If you do paid client audits and the writeup is the part that drains you — yes, this earns its $97 within two billable audits. The PDF is what you'd ship anyway, generated in the time it takes to make coffee.
If you're a one-site owner doing your own audit twice a year, skip it. You can manually check what this automates, and you'll learn more by doing.
If you're a serious SEO with a real crawler subscription (Screaming Frog, Sitebulb), this is a complement, not a replacement. Use it for the conversion + speed passes, keep the crawler for technical depth.
Buy it if you do 5+ paid audits per month.
For: Freelance SEOs, agencies, and consultants who do 5-30 audits per month and hate writing reports.
Against: You only audit your own site, OR you need deep technical SEO crawling (use Screaming Frog instead).
