Fix Ranking Errors Before Spending on Ads.

You shouldn’t start spending money on advertising if your website has technical flaws. Start small—analyze both the product itself and its technical foundation—before scaling up without limits.

01

Know if your site is ready for real traffic

Get a single 0–100 launch readiness score instead of drowning in obscure metrics. See immediately where your site loses search points and what exact fixes bring the biggest ranking gains.

  • Single launch readiness score out of 100
  • Clear priority breakdown: Content, Technical, Speed & Indexation
  • Actionable checklist with zero technical jargon

Turn search clicks into paying customers

Checking character counts is useless if your messaging misses the mark. SEOFixi verifies that your page titles and headlines (H1) tell Google and prospective buyers the exact same story.

  • Identifies Title ↔ H1 semantic mismatches that confuse buyers
  • Catches missing, duplicate, and cut-off titles on product pages
  • Ensures clean search snippets that win real clicks in Google

Speed is the most critical factor on the web

Every second of delay reduces sales and harms your search engine rankings. Our tool measures Core Web Vitals (LCP, TBT, CLS) and pinpoints performance bottlenecks that aren’t immediately obvious—such as overloaded scripts, "heavy" images, or slow hosting.

  • Clear "Good" vs "Needs work" benchmarks for site load speed
  • Server response time (TTFB) to know if your hosting is holding you back
  • Pinpoints heavy scripts and oversized images before customers bounce

// how it works

Why in-browser auditing is fundamentally better

Traditional scrapers operate from distant cloud servers that get blocked by bot firewalls and cannot see private sites. SEOFixi runs through your authentic Chrome browser.

  1. Add the extension

    Install SEOFixi from the Chrome Web Store in one click. Runs 100% locally on your computer with zero setup.

  2. Scan your full site

    Works on live websites, localhost, private staging, and JavaScript SPAs. Discovers and audits every page on your domain.

  3. Fix what matters first

    Review real technical errors prioritized by ranking impact. Fix the root issues, re-scan, and verify improvements.

Traditional Cloud Crawlers

External Scrapers & Cloud Bots

Old-school scraper bots that run from distant data centers and generate bloated spreadsheets with thousands of trivial notices.

  • Dumps thousands of minor notices Fills reports with trivial tags and informational bloat, burying critical indexing bugs under thousands of rows.
  • Blocked by Cloudflare and bot firewalls External scraper IPs get stopped by captchas, rate limits, and bot-detection shields before finishing the scan.
  • Blind to localhost, staging and auth Unable to inspect local development projects (localhost:3000), staging environments, or sites behind passwords.
  • Fails on modern JavaScript SPAs Reads only raw static HTML, completely missing content and links rendered dynamically by React, Vue, or Next.js.
  • Uploads your data to third-party clouds Requires server credits and stores your internal URLs, pre-launch code, and site data on outside servers.
SEOFixi In-Browser Engine

Real Errors & Actionable Diagnostics Only

Professional in-browser engine. It audits through your authentic browser identity, executes JavaScript naturally, and keeps 100% of your data private.

  • Strictly actionable errors & warnings Zero trivial noise or vanity charts. Every warning points to a specific issue that directly impacts search rankings.
  • Full deep scan of all discoverable pages Automatically follows internal links and crawls your entire domain page-by-page, not just a superficial homepage sample.
  • Audits localhost, staging & auth pages If you can open it in Chrome, SEOFixi can audit it. Catch technical SEO mistakes before deploying code to production.
  • Full JavaScript & SPA rendering Audits through Chrome's authentic DOM engine, executing React, Vue, Next.js, and client-side code just like Googlebot.
  • 100% local privacy — zero data leaves your PC Runs entirely on your machine. Your source code, staging URLs, passwords, and audit reports never touch external servers.

// 80+ technical checks

Every factor that impacts search traffic

SEOFixi runs over 80 checks on every audit — first inspecting each page live as Chrome renders it, then analyzing your entire domain architecture for hidden gaps. Zero vanity metrics, just clear answers on what to fix.

Titles & Descriptions

What searchers see in Google before deciding to click.

  • Missing, duplicate, or overly short page titles
  • Descriptions that exceed character limits and get cut off
  • Canonical tags accidentally pointing bots to the wrong URL
  • Open Graph & Twitter card previews for clean social sharing
Headings & Text Quality

Helpful, well-structured text that search engines trust.

  • Missing, duplicate, or multiple H1 headings on a page
  • Thin pages with too little helpful text for searchers
  • Duplicate or copy-pasted content across different URLs
  • Topic mismatch between your headline (H1) and page title
Images & Media

Fast-loading visuals that bots and users can understand.

  • Images missing alt text for screen readers and search bots
  • Heavy image file sizes that slow down mobile visitors
  • Uncompressed pictures missing modern WebP format
  • Broken image paths resulting in blank media and 404 errors
Code, Mobile & SPAs

Clean HTML and JavaScript that loads smoothly on all devices.

  • Full rendered DOM inspection for React, Vue, and Next.js SPAs
  • Oversized page code and bloated DOM trees that slow crawlers
  • Cluttered inline scripts that delay page rendering
  • Missing mobile viewports and responsive layout errors
Speed & Performance

Fast load times that keep visitors from bouncing.

  • Core Web Vitals: LCP (loading), TBT (interactivity), CLS (stability)
  • Server response time (TTFB) before page content begins loading
  • Render-blocking styles and scripts delaying initial display
  • Missing browser cache headers forcing repeat downloads
Links & Site Structure

How easily Google and real visitors discover all your pages.

  • Lost orphan pages with no internal links pointing to them
  • Important pages buried too many clicks away from home
  • Malformed URL structures, double slashes, and broken links
  • Too many outgoing links draining your page authority
Indexation & Redirects

Making sure your best pages actually get indexed by Google.

  • Broken redirect chains and endless loops that trap crawlers
  • Temporary 302 redirects failing to pass search ranking value
  • Dead links and 404 error pages that waste crawl budget
  • Accidental noindex tags hiding valuable pages from Google
Security, Sitemaps & AI

Site foundations, search sitemaps, and new AI engines.

  • Mixed content warnings, SSL certificate health, and HTTPS rules
  • Split traffic between www and non-www versions of your domain
  • XML sitemaps missing fresh URLs or pointing to broken links
  • robots.txt and llms.txt validation for Google, ChatGPT, and Claude

Frequently asked questions

Everything you need to know about SEOFixi and in-browser audits.

Is my website data private? Does anything leave my computer?

Zero data leaves your computer. Cloud-based crawlers upload your website files, internal URLs, and code to third-party servers. SEOFixi runs 100% locally on your machine. Your private pages, staging URLs, source code, and audit results remain strictly inside your browser.

Does SEOFixi audit my whole website or just a few sample pages?

SEOFixi audits your complete active website architecture, not just a superficial sample. Much like Googlebot, it crawls breadth-first through your internal links to inspect the core pages that drive search traffic and conversions. It focuses on your live, discoverable content — without wasting time wandering into deep historical archives, endless paginations, or obsolete legacy URLs that hold zero business value.

Can I audit localhost, private staging, and pages behind logins?

Yes. Because SEOFixi operates directly through your authentic Chrome session, it has the exact same network access you do. You can audit local test servers like localhost:3000, pre-launch staging sites, private intranets, and pages behind password logins without configuring proxies or getting blocked by bot firewalls.

Does SEOFixi work with modern JavaScript SPAs (React, Vue, Next.js)?

Yes. Traditional crawlers only fetch static HTML files and fail to see content rendered by JavaScript. Because SEOFixi runs inside Chrome, it executes client-side JavaScript and inspects the fully rendered DOM exactly like Googlebot and real visitors see it.

Does SEOFixi output trivial notices or only actionable errors?

SEOFixi is designed specifically to eliminate noise. Many tools flood you with thousands of cosmetic notices just to inflate report sizes. SEOFixi surfaces only actionable errors and warnings that directly hurt search engine rankings and indexing, so you know exactly where to take action.

What do the scores mean?

You receive an overall site health score out of 100, plus separate scores for Content, Technical SEO, Resources, and Indexation. The scores reflect your site's readiness for search engines and immediately show you which section has the biggest ranking penalties.

Can I compare audits over time to verify my fixes?

Yes. You can save multiple websites in My Domains and run fresh scans whenever you update your code. The Scan Comparison feature lets you inspect two audits side-by-side to verify that your fixes worked and ensure no new technical regressions occurred.

Which browsers are supported?

Any Chromium-based browser that supports Chrome Web Store extensions: Google Chrome, Microsoft Edge, Brave, Arc, and Opera.

Audit your full website in minutes.

Inspect every page on live websites, localhost, and staging environments. 100% private, completely in your browser.
