20 reasons teams switch to Seraph

"We ran our first Seraph audit expecting the usual title-tag checklist. Instead we got a full LLMO breakdown showing exactly why ChatGPT wasn't citing us. Fixed the three flagged issues and saw citation appearances in Perplexity within two weeks."

MT
Marcus T.
Head of SEO · TechFlow SaaS

"I'd been paying £800/month for an SEO agency that never once mentioned LLM optimization. Seraph showed me what they were missing in under a minute. Cancelled the retainer the same day."

PN
Priya N.
Founder · Nomad Stack

"The LLM fix prompts alone are worth the subscription. I paste them into Claude and get production-ready schema markup in seconds. What used to take our dev team a sprint now takes an afternoon."

JC
Jordan C.
Growth Lead · Elevate Commerce

"Seraph's schema scoring caught six critical errors our previous tool had flagged as 'warnings' for six months. Two of them were suppressing our rich results entirely. Fixed, deployed, rich snippets back within 72 hours."

SM
Sarah M.
VP Marketing · Orbit Analytics

"Finally a tool that treats LLMO as a first-class discipline rather than an afterthought. The citation readability score is genuinely novel — I haven't seen anything like it elsewhere."

DK
Daniel K.
Technical SEO · CloudBridge

"I'm not a developer but Seraph's recommendations are written so clearly I can implement half of them myself. The rest I hand to our engineer with the attached fix prompt — no back-and-forth required."

AO
Amara O.
Content Strategist · Pulse Media

"We integrated Seraph into our pre-launch checklist for every client site. The 54-point audit catches things we used to discover post-launch in our analytics. It's become a non-negotiable step."

LF
Liam F.
CTO · Foundry Labs

"Running audits for 12 client sites every month used to mean 12 different spreadsheets. With Seraph I get structured, comparable reports across all of them in a format our clients actually read."

NW
Nina W.
Digital Director · Stellar Agency

"I built a niche SaaS and couldn't afford an SEO consultant. Seraph gave me exactly what I needed — a prioritized list of what to fix first, with the actual code to fix it. Organic traffic up 40% in three months."

TB
Tom B.
Indie Dev

"The E-E-A-T scoring section revealed that our author pages were doing serious trust damage. Nobody had flagged this before. We rebuilt the author bios, added schema, and our content started getting cited in AI overviews within a month."

KS
Keiko S.
Product Manager · Arca Tools

"Seraph is the only audit tool I've seen that scores both Google visibility and AI answer engine presence in one pass. That dual-channel view is exactly what modern SEO teams need."

RM
Rafael M.
SEO Manager · BrightEdge Co.

"We had schema markup but it was full of errors we didn't know about. Seraph's schema validator is more thorough than Google's own Rich Results Test — it caught three issues the Google tool missed."

CD
Chloe D.
Head of Growth · Tessera App

"I recommend Seraph to every client in their first call now. The report is professional enough to share with a board and detailed enough to hand straight to an engineer. It's replaced three tools in my stack."

AP
Aiden P.
Freelance SEO

"Our Core Web Vitals were tanking our LCP score and we didn't realize it was also hurting our AI citation potential. Seraph connected those dots explicitly. The fix prompt even included code for our specific Shopify theme."

ML
Mei L.
Marketing Director · Vanta Retail

"Signed up skeptically. The LLMO audit showed that three of our top-performing blog posts had zero entity signals and were invisible to AI answer engines despite ranking well on Google. That was a wake-up call."

OH
Oliver H.
Startup Founder · Crest AI

"The prioritized fix list is what sets Seraph apart. Other tools give you 200 issues with no sense of what matters. Seraph ranks everything by impact so I know exactly where to spend our limited sprint capacity."

FA
Fatima A.
SEO Lead · Noor Digital

"I appreciated that the fix prompts are LLM-agnostic. I tested three of them in Claude, ChatGPT, and Gemini — all produced working code. That's not something you can say about most AI-optimized content."

BR
Ben R.
Engineering Lead · Stackr

"Seraph caught that my client's site had conflicting canonical tags across 40 pages — a crawl budget disaster we'd been ignoring for two years. Fixed in one afternoon using the exported fix prompts."

YT
Yuki T.
Consultant · Solo

"The trust signals section is something I've never seen in any SEO tool. Seraph flagged that we had no visible security badges, no clear privacy summary, and inconsistent author attribution — all of which AI systems use to assess credibility."

GN
Grace N.
Brand Manager · Soleil Co.

"As someone who lives in Lighthouse and CrUX data, I was impressed that Seraph's performance section goes beyond the basics. It connected our poor TTFB directly to our LLMO authority score — a link I hadn't made explicit before."
