Caution

Survival RateConversion Probability

Nearly half your visitors bounce before they figure out what you sell — basics, luxury, or limited drops? They can't tell, so they leave.Modeled conversion likelihood sits above median, but the drop-off cohort correlates with above-the-fold message latency.

Strong

Corporate FluffLexical Fluff Density

Direct and lethal — no "innovative", no "seamless", no buzzword sludge. This is exactly how copy should read.Filler-phrase ratio sits at the floor. Minimal lexical noise; entity signal is clean and undiluted.

Critical

Cognitive LoadCognitive Load Index

Academic friction. Lifestyle poetry like "soul of the ocean" buries the actual product — nobody should have to decode a homepage.Flesch-Kincaid syntactic load runs above the sub-3-second comprehension threshold. Sentence complexity is taxing parse time.

Critical

Message ClaritySemantic Message Score

Premium pricing with no fiber specs, no GSM, no reason to believe. Visitors can't tell why it costs what it costs — so they don't buy.Primary value proposition fails to resolve. Weak message-to-intent alignment against the target query.

Caution

AI LegibilityLLM Indexation Score

ChatGPT only half-gets the page. Passive voice and vague sustainability jargon make it harder for AI to surface you when buyers ask.Generative-engine legibility sits mid-band. Passive constructions and weak entity structure limit retrieval in LLM answers.

Scores like these usually mean a page is quietly losing customers. The fix list tells you exactly what to change.

Signal confirmed. Structural deficiencies detected across three primary conversion layers.

Run the free scan. Let the product do the talking. When real founders say real things about it, they'll appear here — names, sites, receipts. Run the core scan against your own property. Score accuracy is verifiable in under 60 seconds, which beats any testimonial we could type ourselves.

Built on

Everything broken. Everything fixed. One coffee price. The complete optimization payload. Deployed on demand.

Eight engines. One $9 payment. Not per month, not per seat. Full-stack semantic, technical, and competitive output. Single-transaction.

01

The Fix-It Engine Syntactic Optimization Engine

The sentences that sounded great when you wrote them at midnight? Rewritten. Our AI has processed more underperforming landing pages than any consultant you could hire, and it doesn't sugarcoat. Production-ready rewritten copy engineered to minimize reading friction and cognitive load across your conversion-critical page layer. Processed by Claude Sonnet — not Haiku.

02

A/B Copy Variants A/B Hero Variant Generation

Three versions of your hero, three different angles. Run all three. Keep the one that converts. Or just pick the one that sounds most like you — we'll have opinions either way. Multi-variant SERP-contextualized hero rewrites optimized against distinct intent clusters extracted from live competitor data.

03

Google Preview Fix Search Storefront Optimizer

The two lines of text Google shows about you before anyone visits. Most founders have never looked at them. Ours are written to get clicked. You get the exact text — under the character limit, ready to paste. Optimized title tag (60 char) and meta description (155 char) generated against live SERP context. Plain-English explanation of why the existing preview is losing clicks.

04

Competitor Shadow Report LSI Cluster Blueprint + Competitor Vector Analysis

We look at the sites ranking above you and map exactly what they're doing that you're not. The words they use, the structure they follow, the topics they cover. It's occasionally humbling. It's always useful. Real-time entity gap analysis against top three SERP competitors. Volume deltas, intent misalignments, missing latent semantic terms, and structured topical coverage gaps.

05

Head-to-Head Showdown Versus Dashboard

Your site's numbers next to your competitor's. Every metric, side by side. One of you is clearly winning this. Now you'll know which one it is. Dual-URL comparative audit across fluff density, PageSpeed, semantic clarity, and LLM crawlability.

06

SEO Blueprint Technical SEO Payload

Your page title, headings, image descriptions, and meta tags — the things no visitor ever reads and Google reads constantly. Corrected, written, and ready to paste. Canonical validation, H1/H2 schema mapping, alt-text coverage, meta-description CTR optimization.

07

Shareable Report White-Label Permanent URLs

A permanent, no-watermark link to your full report. Send it to your developer, your designer, or your next agency when they claim to already know what's wrong. Permanent scan URLs for client-facing delivery. Unbranded PDF export formatted for agency presentation decks.

Bloated tools create chores. CipherSEO delivers answers. Legacy platforms audit infrastructure. We audit the conversion layer.

Here's exactly how it works. Three-node processing pipeline.

No black box. No magic. A very fast engine doing three things in sequence. Parallel multi-source ingestion → analytical vectoring → structured payload compilation.

01

The Scrape Extraction Node

Paste a URL. Three things fire at once — in parallel, not in sequence. Three ingestion pipelines fire concurrently the moment a URL is submitted.

  • Your copy — we pull and read the full text of your landing pageCopy corpus — full DOM text parse of the landing page
  • Your competitor — a live Google search pulls your top competitor's dataCompetitor set — live SERP extraction pulls the top organic competitor
  • Your speed — a PageSpeed check runs on desktop and mobilePerformance delta — PageSpeed Insights, desktop + mobile

Under 30 seconds later we have your copy, your competition, and your performance baseline — before scoring even starts. Most SEO audits stop at your own page; we build the comparison first, so the verdict tells you where you stand against whoever's beating you. PageSpeed never blocks the AI layer. The comparison set is built before scoring begins, so every verdict is relative to live competitors — not an absolute score in a vacuum.

02

The Roast Analytical Vectoring

Your copy runs through five scoring layers — three by math, two by AI. Five metrics: three deterministic, two model-scored via Claude Haiku.

  • BS % — how much of your copy is empty fillerlocalLexical density — filler-phrase ratiolocal
  • Cognitive load — how hard your sentences are to parselocalCognitive load — Flesch-Kincaid complexitylocal
  • Survival rate — your speed percentile vs the competitorlocalSurvival rate — PageSpeed competitive percentilelocal
  • Message clarity — do people get what you sell in 3 secondsAIMessage clarity — semantic intent-node resolutionAI
  • AI legibility — can ChatGPT actually read your pageAIAI legibility — LLM entity crawlabilityAI

Every score is calibrated to your industry — ecommerce, SaaS, AI tools, DTC, and micro SaaS each scored on their own standard, never one universal threshold. "Add to Cart" is right on a product page and suspicious on a B2B platform; the engine knows the difference. Industry-specific jargon dictionaries per vertical — SaaS, ecommerce, AI tools, DTC, micro SaaS thresholds are distinct, not a universal scoring baseline applied across every page.

03

The Fix Payload Compilation

Pay once — less than a coffee. Claude Sonnet runs eight outputs. Single one-time transaction. Eight structured outputs via Claude Sonnet.

Rewritten copy A/B hero variants Google preview fix Competitor shadow Versus dashboard SEO blueprint 30-minute fix list Shareable report
Syntactic rewrite A/B hero gen Storefront optimizer Competitor shadow Versus dashboard Technical SEO 30-min fix list White-label URL

Every output is plain-English and ready to paste. It all lands in a permanent, no-watermark report URL — plus three re-scans. Make the changes, run it again, watch the scores move. Fix, verify, fix again — that loop is the whole point. Sonnet, not Haiku — a materially more capable model than the free scan. Permanent white-label report URL, three re-scans, Tailwind DOM component export. Fix → verify → re-scan loop.

Questions you probably have. Technical and product FAQs.

Honest answers. No FAQ filler. Covering scan methodology, payload scope, and integration.

The core scan — five copy scores, a written verdict, live competitor SERP data, and desktop plus mobile page speed — is completely free. No account, no credit card, no trial that auto-upgrades. You paste your URL and get results in under 60 seconds. The $9 one-time payment unlocks eight fix engines: AI-rewritten copy, A/B hero variants, a Google search preview fix (exact title and meta description ready to paste), a competitor shadow report, a 5-article content roadmap, a head-to-head versus dashboard, technical SEO corrections, and a permanent shareable report URL. Three re-scans are included so you can verify your fixes actually moved the scores.

CipherSEO checks five core dimensions: the percentage of your copy that is generic filler (Corporate Fluff), how hard your page is to read without getting lost (Cognitive Load), how clearly your page communicates what you do and for whom (Message Clarity), how your page speed compares to your competitors (Survival Rate), and how likely AI assistants like ChatGPT and Perplexity are to surface your page as a trusted answer (AI Legibility). The paid report also checks your title tags, H1, meta description, image alt-text, canonical tags, and competitor keyword gaps.

Ahrefs and Semrush are powerful tools built for full-time SEO professionals managing large sites and complex campaigns. They cost $100–$400 per month and require significant expertise to use well. CipherSEO is built for founders and small teams who need a clear, plain-English verdict on a single landing page — and who don't have the time or budget to become SEO experts. Rather than showing you a database of keywords and backlink graphs, CipherSEO reads your actual copy, scores it, rewrites what's failing, and hands you the fixed version in a format you can act on today.

The free scan typically completes in 30 to 60 seconds. The paid fix report — which runs competitor analysis, generates copy rewrites, builds A/B variants, and compiles the versus dashboard — takes approximately 2 to 3 minutes to process. You will see live progress as each engine node completes. We know waiting is irritating, which is why we show you what the engine is doing in real time rather than a generic spinner.

No. The free scan requires no account and no email address. If you choose to unlock the $9 fix report, you will provide an email address for delivery of your permanent report URL — that is the only data we collect during checkout. No password. No onboarding flow. No welcome sequence.

The $9 one-time report includes: AI-rewritten copy for your failing sections (processed by Claude Sonnet, not the free tier model); two to three A/B hero section variants built from live SERP data; a Google search preview fix — the exact optimized title tag and meta description to paste straight into your CMS; a competitor shadow report showing what your top competitors cover that you don't, plus a side-by-side fluff index and friction score comparison; a head-to-head versus dashboard comparing every metric against a competitor you specify; a 5-article content roadmap with plain-English reasoning for each piece; technical SEO corrections covering H1, canonicals, alt-text, and structured data; production-ready code blocks with your new copy formatted to drop straight into your site; 3 re-scans so you can verify your fixes actually moved the scores; and a permanent shareable report URL with no watermark or expiry. That is everything. There is no further upsell.

Yes — SaaS, ecommerce, AI tools, DTC brands, micro SaaS, marketplaces, agency sites, and any other conversion-focused startup page. CipherSEO uses industry-specific jargon dictionaries to calibrate its scoring per vertical. It knows that "Add to Cart" is correct on an ecommerce product page but out of place on a B2B platform, that AI tool copy carries different expected vocabulary than a subscription SaaS, and that a DTC brand page should read nothing like an enterprise software homepage. Your fluff score, clarity score, and rewrite suggestions are all calibrated to your actual industry — not a generic standard that treats every page the same. The only pages we cannot scan are those behind a login or on a private network.

For a page you are actively sending paid traffic to, audit after any major copy change, before and after a paid campaign launch, and whenever you notice a significant drop in conversion rate or search ranking. The audit captures a real-time snapshot against your current live SERP competitors — so results will shift as those competitors update their own pages. Monthly is reasonable for a high-traffic landing page. Quarterly is sufficient if traffic is low or the page is relatively stable. The $9 is per scan — run it whenever something changes.

Get the fix. Stop losing the sale. Deploy the complete optimization payload.

One payment. Every fix. We really mean it about the not-per-month part. Single-transaction payload. No seat licensing. No subscription overhead. No renewal.
