A site audit tells you which pages have problems. A page audit tells you exactly what is wrong with a specific URL. The two tools answer different questions — and most SEO workflows need both.
The ten on-page signals our audit checks
- Title tag — presence, length (30–65 characters), and whether it is unique.
- Meta description — presence and length (100–165 characters). Controls your Google snippet.
- H1 heading — detects missing H1s and pages with more than one H1.
- H2 structure — lists subheadings so you can review content hierarchy at a glance.
- Canonical URL — checks for a self-referencing canonical to prevent duplicate-content dilution.
- Robots meta — flags accidental noindex or nofollow directives.
- Open Graph and Twitter Card — verifies og:title, og:description, og:image for correct social previews.
- Image alt text — counts images with missing or empty alt attributes.
- Schema.org JSON-LD — detects structured data types that qualify pages for rich results.
- HTTP security headers — scores HSTS, CSP, X-Frame-Options, Referrer-Policy, and Permissions-Policy.
Title tag: the highest-leverage fix in on-page SEO
Google uses the title tag as the primary signal for what a page is about — and as the default headline in organic results. A title that is 80 characters long gets truncated in search results, cutting off the keyword at the end. A title that is 25 characters is almost certainly not targeting a specific query. The optimal range is 30–65 characters, with the primary keyword toward the front.
Our audit flags too-short and too-long titles so you can fix them before they become a ranking bottleneck.
Canonical tags: the most under-audited technical element
Most CMS platforms generate multiple accessible URLs for the same content:
with and without a trailing slash, with ?ref= UTM parameters,
via HTTP and HTTPS, or via www and non-www.
Without a canonical tag, Google must decide which version to index — and often splits PageRank across all of them.
A self-referencing canonical on every indexable page is the simplest way to prevent this.
From single audit to continuous monitoring
Running a one-off page audit catches the issues that exist right now. But on-page SEO elements change: CMS updates rewrite titles, deploys accidentally remove canonical tags, migrations flip noindex on production pages. 2-UA monitors every tracked URL on a daily crawl schedule and sends an alert the moment a monitored element changes.
Use the free page audit to diagnose a specific URL today, then set up monitoring to make sure it stays correct tomorrow.
