What this SEO page audit checks

HTTP Status, Redirects & Final URL

Audits indexability entry conditions: status code, redirect chain length, and landing URL.

Robots.txt + Robots Directives

Checks robots.txt reachability, potential path blocking, meta robots, and X-Robots-Tag directives.

Title Tag

Detects missing, duplicated, too-short, and too-long titles.

Meta Description

Checks presence, duplicates, and length quality for SERP snippet control.

Heading Structure

Flags missing/multiple H1 and lists H2 headings for hierarchy review.

Canonical Signals

Detects canonical-to-URL mismatches, HTML vs HTTP canonical conflicts, cross-domain targets, and malformed canonical URLs.

Content Depth Signals

Computes word count, reading time, and text-to-HTML ratio to highlight thin pages.

Link Profile Snapshot

Counts internal/external/nofollow links and surfaces top external domains.

Image SEO + CLS Hints

Checks missing alt, empty alt, missing width/height, and lazy-loading coverage.

Structured Data & Hreflang

Parses JSON-LD validity/types, microdata itemscope, hreflang inventory, and x-default presence.

Rendering & Asset Pressure

Measures DOM size, script/style counts, blocking head scripts, and 304 Not Modified support.

HTTP Security Headers

Scores HSTS, CSP, X-Frame-Options, Referrer-Policy, and Permissions-Policy against recommended values.

Why audit a page before you publish — or after every change

A single missing canonical tag or an accidentally duplicated H1 can cost you rankings for months before you notice the drop. Google re-crawls pages on its own schedule — by the time Search Console reports the issue, the damage is already done. Running an SEO page audit before publishing and after every content update catches these issues in seconds, at no cost.

Our audit checks every technical on-page factor in a single pass: the same signals SEO professionals review manually, automated into a 10-second report. You don't need a Screaming Frog licence or an Ahrefs subscription to find out whether your title is 80 characters long.

Frequently asked questions

An SEO page audit is a technical analysis of a single webpage that checks whether all on-page ranking factors are correctly implemented. It covers metadata (title, meta description), heading structure (H1, H2), canonical tags, social meta tags (Open Graph), structured data (Schema.org), image alt text, and HTTP security headers. The goal is to find issues that prevent a page from ranking as well as it could.

A full site audit (like our free online crawler) crawls every URL on your domain and reports aggregated issues across all pages — duplicate titles, broken links, crawl errors. A page audit goes deeper on a single URL, examining every on-page signal in detail. Use the crawler to find which pages have problems; use the page audit to diagnose exactly what is wrong with a specific URL.

The rel="canonical" tag tells Google which version of a URL to index when the same content is reachable via multiple URLs (e.g. with and without a trailing slash, with UTM parameters, or via HTTP and HTTPS). Without a canonical, Google must guess — and may split PageRank across duplicate versions, weakening rankings for all of them. A self-referencing canonical is best practice for every indexable page.

Not directly as a ranking factor — but HTTPS (enforced by HSTS) is a confirmed ranking signal, and poor security headers can trigger browser warnings that increase bounce rate and reduce time-on-site. More importantly, missing headers like Content-Security-Policy and X-Frame-Options expose your site to XSS and clickjacking attacks, which can lead to malware injection that gets your site penalised or delisted entirely.

Schema markup is not a direct ranking factor, but it enables rich results (star ratings, FAQ dropdowns, product prices, breadcrumbs) that significantly increase click-through rate in search results. Pages with rich results typically outperform those without them — the higher CTR signals relevance to Google, which indirectly improves rankings over time.
