SEO Meta Tag Audit: Titles, Descriptions, Canonicals & Schema

Audit every page's title, meta description, canonical, H1, Open Graph tags, hreflang and schema in one run, and get a worst-first list of fixes with a 0-100 score per page.

This is a bulk on-page SEO check. Give it a site (or a sitemap, or a list of pages) and it checks the things that usually go wrong: missing or overlong titles, duplicate meta descriptions, canonicals that point somewhere else, pages with no H1 or three of them, missing Open Graph images, invalid JSON-LD and images without alt text. Every page gets a 0–100 score and a list of issues written in plain English.

There's no browser and no AI, just quick HTTP fetches and rule-based checks. That keeps it cheap enough to run on every page of a site every week.

Who it's for

• Freelancers and agencies who need an audit before quoting a client. The HTML report in the key-value store is ready to send.
• Site owners who want to know which pages need new titles and descriptions, sorted worst first.
• Developers running a check before or after a launch, a theme change or a migration. Compare two runs to catch regressions such as a lost canonical or a new noindex.
• Content teams hunting duplicate titles and descriptions across hundreds of posts.

What it checks

Area	Checks
Title	missing, under 30 or over 60 characters, multiple title tags, duplicates across pages
Meta description	missing, under 70 or over 160 characters, duplicates across pages
Indexing	noindex / nofollow in meta robots or the X-Robots-Tag header, HTTP errors, redirects
Canonical	missing, more than one, pointing to another URL, invalid
Headings	no H1, empty H1, several H1s, H2 count
Mobile & basics	viewport tag, lang attribute, charset, favicon
Social	og:title, og:description, og:image (and whether it's absolute), twitter:card
International	hreflang list, invalid language codes, missing x-default
Structured data	JSON-LD and microdata types found, JSON-LD that doesn't parse
Images	images without an alt attribute
Other	mixed http content on https pages, thin pages (under 200 words), HTML size, slow server response

Scoring: start at 100, subtract 15 per error, 5 per warning and 1 per notice. Pages that return an HTTP error score 0. The score is for sorting and tracking over time. It isn't a ranking prediction.

The key-value store also gets:

• SUMMARY: pages audited, average score, and how many pages have each issue.
• REPORT: an HTML report with issues by type and every page, worst first.

Pricing

In plain words: $4 per 1,000 pages audited (that's $0.004 per page), plus Apify's small standard Actor start fee. A 100-page site costs about $0.40.

• You only pay for pages that are actually audited and saved.
• Set maxPages, or a maximum cost per run, and the Actor won't go past it.
• No headless browser is used, so platform usage stays very low.

FAQ

Does it render JavaScript? No. It reads the HTML the server returns, which is also what most search engines see first. If your titles or meta tags are added only by JavaScript, the audit reports them as missing, and you'll want to know that anyway.

Are the character limits exact? No. Google truncates by pixel width, not by character count. 60 characters for titles and 160 for descriptions are safe rules of thumb, so long titles are flagged as warnings, not errors.

Does it check page speed or Core Web Vitals? It records server response time and HTML size. For full Lighthouse metrics, use a dedicated tool. This Actor sticks to meta tags and markup.

Does it validate structured data against Google's rich-result rules? It lists the schema types it finds and flags JSON-LD that doesn't parse. It doesn't run Google's rich-result eligibility rules.

Can I audit a site I don't own? Auditing public pages is like viewing the page source in your browser. The Actor respects robots.txt and keeps load low by default. Follow each site's terms.

Crawl or sitemap mode? Sitemap mode audits what you tell search engines exists. Crawl mode audits what a visitor can reach by clicking. Running both and comparing them is a quick way to find orphan pages.

Related tools

These work well together for a quick technical SEO check:

• Broken Link Checker: find 404 errors, dead links and redirect chains across a whole site.
• Sitemap & RSS Feed Exporter: export a sitemap.xml or RSS feed to CSV, Excel or JSON.

Typical workflow: export the sitemap first, then run this Actor in list mode on exactly the pages you care about.
