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

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.

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

Everything else on this market was designed for teams with a dedicated SEO manager and a six-figure budget. You don't have either of those things. Standard platforms are keyword databases with no copy output and no conversion-layer analysis.

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

You paste a URL. The moment you hit run, three things happen simultaneously: we pull the full text of your landing page, run a live Google search to pull your top five competitors' data, and fire a PageSpeed request against both desktop and mobile. In under 30 seconds we have your copy, your competitive landscape, and your performance baseline — in parallel, not in sequence. No waiting for one to finish before the next starts. Most SEO audits stop at crawling your own page. We build the comparison set before we even start scoring, which is why our verdict tells you where you stand relative to the people currently beating you. Parallel multi-source ingestion via Serper.dev SERP extraction, Jina AI DOM parse, and Google PageSpeed Insights API. Outputs: raw copy corpus, competitor URL set (top 3 organic), DOM structure map, desktop/mobile performance delta. All three pipelines fire concurrently — PageSpeed does not block the AI analysis layer.

02

The Roast Analytical Vectoring

Your copy runs through five scoring layers. Three are computed locally — no API, no model, just deterministic math against your actual text: your BS percentage (how much of your copy is empty business filler), your cognitive load score (how hard your sentences are to parse), and your survival rate (your page speed percentile against the competitors we just pulled). The other two are scored by AI: message clarity (does your page communicate what you sell in the first three seconds?) and AI legibility (would ChatGPT or Perplexity cite you as a trusted answer?). Every score is calibrated to your industry. Ecommerce copy is scored differently from SaaS copy, which is scored differently from AI tool copy or a DTC brand page. The engine carries separate jargon dictionaries per vertical — it knows that "Add to Cart" is correct on a product page but suspicious on a B2B platform, that enterprise SaaS copy should sound different from micro SaaS copy. Your fluff score reflects your actual industry standard, not a universal threshold that treats every landing page the same. Three locally computed metrics via core.linguistics: lexical density ratio (fluff score), Flesch-Kincaid syntactic complexity (cognitive load), PageSpeed competitive percentile (survival rate). Two AI-computed metrics via Claude Haiku: semantic intent-node clarity (message clarity), LLM entity crawlability score (AI legibility). Industry-specific jargon dictionaries applied per vertical — SaaS, ecommerce, AI tools, DTC, micro SaaS scoring thresholds are distinct.

03

The Fix Payload Compilation

For $9 — once, not monthly — the fix engine runs eight separate outputs using Claude Sonnet (a significantly more capable model than the free scan). Your failing copy gets rewritten. Three different hero versions get generated against live SERP context so you have variants to test. Your Google search preview gets fixed — meaning you receive the exact optimized title and description, under the character limits, ready to paste into your CMS today. A competitor shadow report maps the specific topics your competitors cover that you're missing, with a side-by-side fluff and friction comparison. A content roadmap gives you five specific articles to publish, with plain-English reasoning for why Google needs to see each one from you. And everything lands in a permanent report URL with no watermark, no expiry, and no login required to view it — shareable to a developer, a designer, or a co-founder without any friction. You also get three re-scans included. Make the changes, run it again, see if the scores moved. That loop — fix, verify, fix again — is the whole point. Eight structured outputs via Claude Sonnet: syntactic rewrite layer, multi-variant A/B hero generation, Google storefront optimizer (title tag + meta description), competitor shadow analysis (entity gap + BS/friction delta), semantic content roadmap (5 briefs), head-to-head versus dashboard, technical SEO payload (H1, canonicals, alt-text), Tailwind DOM component export. Three re-scans. White-label permanent report URL.

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.
