The Problem
Every SEO tool shows you what's broken. None of them fix it.
Audit tools give you a list.
A 200-row spreadsheet of broken things. No priority. No fix included. Every change still has to be written by hand.
JS overlays disappear when you cancel.
Third-party scripts inject meta tags at runtime. Cancel the subscription and your SEO reverts overnight — silently.
Nothing talks to your CMS.
Every fix lives in a dashboard. Translating recommendations into WordPress, Shopify, or Webflow is always on you.
How It Works
Three steps. Zero manual work.
Crawl every page. Find every issue.
Sernix schedules automatic crawls and runs 12+ checks per page — title length, meta description, structured data, Core Web Vitals, broken links, and more. No setup required.
AI writes the fix. You own the decision.
For each issue, Sernix generates a production-ready rewrite — a new title, meta description, or JSON-LD block — surfaced as a diff. Review it, approve it, skip it. It's your site.
WordPress
written
Shopify
synced
GitHub PR
merged
Written to your CMS. Verified 24 hours later.
Approved fixes deploy directly to your CMS — WordPress via the bridge plugin, Shopify via API, or as a GitHub PR for code-based sites. Sernix re-crawls the next day to confirm the change held.
Features
Built for the work, not the demo.
Most tools flag titles over 60 characters. Sernix renders the page, measures the actual pixel width in Google's font, and calculates whether the title truncates in SERP — across all screen widths.
Sernix generates a rewrite for every issue — not a template, not advice. A production-ready title, meta description, or JSON-LD block. Review the diff, approve it, or edit before deploying.
Sernix crawls your site, detects SEO issues with AI, and deploys fixes directly to your CMS — verified 24 hours later.
Approved fixes go directly into your CMS — WordPress via the bridge plugin, Shopify via API, or as a GitHub PR for code-based sites. No JavaScript overlay. No dependency on a live subscription.
Sernix re-crawls 24 hours after every deploy to confirm the change held. If someone manually overwrites it, or a plugin reverts it, Sernix detects the drift and flags it for re-deploy.
Connect Google Search Console and see clicks, impressions, CTR, and average position per page — plotted against your Sernix fix timeline so you can see exactly what moved the needle.
Schedule daily, weekly, or on-deploy crawls. Sernix sends alerts only when high-impact issues appear — not a wall of minor warnings. Your inbox stays clean; nothing critical slips through.

AI crawlers hit your HTML and burn through context tokens on JS layers — your content never makes it into their response. Sernix auto-generates clean page mirrors of every page, registers them via /llms.txt and HTTP Link headers, so GPTBot, ClaudeBot, and PerplexityBot get token-efficient content they can actually cite.
