All free: no signup, no card, no domain limits.

  • Prioritization: critical / important / cosmetic
  • PDF export for client or leadership presentation
Coverage

What's in the audit

The audit groups by logical block because technical issues rarely come alone — if a site is slow, it usually has indexing issues too. Each block scores 0–100 separately and at the end you get an overall grade. Solid sites score 85+. Anything critical drops you under 50, and the report shows exactly which check pulled the score down.

Indexing
robots.txt, sitemap.xml, canonical, noindex, X-Robots-Tag, hreflang.
On-page
Title, description, H1–H6, alt text, content length, keyword usage.
Speed
Core Web Vitals (LCP, INP, CLS), TTFB, bundle size, image optimization.
Security
HTTPS, CSP / HSTS headers, SSL expiry, mixed content.
Mobile
Viewport, tap targets, font size, Google mobile-friendly test.
Schema.org
JSON-LD validation, required fields, Rich Results recommendations.
Indexing

Indexing and crawl audit

The biggest technical problem on most sites is that engines either don't reach parts of the site, or reach them but don't index, or index but forget. The audit walks the whole chain: pulls robots.txt and validates syntax, reads sitemap.xml and compares with reality, checks canonical presence and correctness, hunts for conflicts between meta robots and the X-Robots-Tag HTTP header, validates hreflang for multilingual sites, scores page depth from root.

  • robots.txt validation + Googlebot / YandexBot access check
  • sitemap.xml parse and full URL walk
  • Pages with conflicting canonical
  • Conflicts between meta robots and X-Robots-Tag — a common silent bug
  • Hreflang: reciprocal links and region validation
Core Web Vitals

Speed and Core Web Vitals audit

Speed has been an official Google ranking factor since 2021, and Russia is no different — Yandex weights technical page metrics too. The audit pulls Core Web Vitals from real user data over the last 28 days (CrUX field data) plus a synthetic Lighthouse run for lab conditions. We show numbers and concrete asks: "shrink the hero image 40 % to drop LCP from 3.2 s to 2.0 s".

LCP
≤ 2.5 s
Largest contentful paint
INP
≤ 200 ms
Interaction responsiveness
CLS
≤ 0.1
Layout stability
On-page

On-page SEO audit

On-page is the foundation. If the title is empty or duplicates on 80 % of pages, no amount of links or content can save you. The audit checks title length (50–60 chars) and description length (140–160 chars), H1 presence and uniqueness, heading hierarchy H1 → H2 → H3 (often broken on home pages), alt attributes on images (matters for image search and accessibility), keyword density, presence of textual content, internal and external link counts.

  • title / description length vs SERP truncation
  • Title duplicates across the site — a common silent traffic loss
  • Heading hierarchy H1 → H2 → H3
  • Alt attributes on all meaningful images
  • Minimum text length on key pages
Security

Security and technical reliability

If your site isn't on HTTPS, engines downrank it. Mixed content (some assets on http) makes the browser flag "not secure" and users bounce. Expired SSL stops half of browsers from loading the site at all. The audit checks all of this plus the right security HTTP headers: HSTS (HTTPS forever), CSP (Content Security Policy), X-Content-Type-Options, Referrer-Policy. It's not "unsafe for the user" — it's "unsafe for traffic".

  • HTTPS and SSL expiry
  • Mixed content: http resources on https pages
  • HSTS header (downgrade protection)
  • CSP, X-Content-Type-Options, Referrer-Policy
  • Exposed ports and outdated server versions
Mobile

Mobile-friendly and responsive

Google has indexed mobile-first since 2019 — the phone version matters more than the desktop one. The audit checks for a correct viewport tag, tap-target size (48 × 48 px minimum), font size (12 px minimum), absence of horizontal scroll, form and button rendering correctness. On top of that we run the site through the Google Mobile-Friendly Test and show the official result.

  • Viewport tag and its parameters
  • Tap-target size (Google's guideline)
  • Minimum font size 12 px
  • No horizontal scroll
  • Google Mobile-Friendly Test — official result
Schema.org

Structured data and rich snippets

JSON-LD markup is the main route to rich SERP snippets: review stars, prices, stock status, FAQ accordions, breadcrumbs. The audit validates markup against the schema.org spec, checks all required fields for the chosen type, hunts for errors (rating without reviews, price without currency), and recommends which types to add for your specific site (Product for e-commerce, Article for blogs, LocalBusiness for offline locations).

  • JSON-LD validation against schema.org
  • Required and recommended field coverage
  • Conflicts between markup and page content
  • Recommendations: which types to add
Use cases

Who the SEO audit is for

The audit serves three typical scenarios. One: a site owner wants a snapshot of their site state right now without paying an SEO agency 30–100 K ₽ for the same report. Two: an SEO uses it as the starting point with a new client. Three: a developer checks site quality before handing it to the client. Across all three, the report has to be readable by a non-SEO yet still ship precise technical recommendations an engineer can execute.

Site owners
See what's wrong and where to spend energy — without paying an agency.
SEO professionals
Report as the starting point with a new client.
Developers
Check site quality before client handoff.
Marketers
Explain to leadership why organic traffic dipped.

Why our audit is different

There are dozens of free SEO checkers out there, but most either run 5–10 basic checks or show the top of the report and ask to pay for the full. Ours gives you the full report up front — 50+ checks with no skip and no upsell. We're not trying to sell you links, "guest posts" or "SEO done for you" — we sell subscriptions to monitoring (Basic / Pro / Agency), and those are optional for the free audit. Russia-hosted, no public storage of audit results.

FAQ

SEO audit — frequently asked questions

Is it really free?

Yes. The audit runs with no signup, no card, no hidden limits. The report shows in full — no "10 issues found, pay to view".

How long does one audit take?

About 30 seconds on average. JavaScript-heavy sites take a little longer — we have to wait for the page to finish rendering before analyzing.

How does this differ from PageSpeed Insights?

PageSpeed Insights only checks speed and Core Web Vitals. Our audit includes PageSpeed as one block, then adds indexing, on-page, security, schema.org, mobile-friendly checks — 50+ parameters total.

Can I audit auth-protected sites?

The free version checks only publicly reachable URLs. If the site is behind HTTP basic auth or requires login, talk to us — paid plans support authenticated crawling.

Can I download the report as PDF?

Yes, there's a "Download PDF" button right on the result page. The PDF is formatted for presentation — works for a client or for leadership.

How does the audit differ from a paid subscription?

The audit is a one-shot snapshot. The subscription is automatic daily monitoring of the same parameters plus rank tracking, backlink analysis, 16 months of history, and drop alerts.

Can I audit a competitor?

Yes, the audit works on any publicly reachable URL. Especially useful before taking on a client — see the technical state of a competitor in the same niche.

Why do you ask for email if there's no signup?

Email is optional — if you want the PDF emailed or want recurring checks. Without email the audit works fine, the report shows in the browser.
