Paste raw HTML to audit title tags, meta descriptions, headings, links, alt coverage, schema, and indexability before you publish or refresh an SEO page.
How to run a better audit
- Paste the full HTML document, especially the <head> tags and main body content.
- Set the primary keyword you want the page to rank for and the real site base URL.
- Review the weighted issues first, then use the metrics and heading outline to confirm structure.
- Export the checklist after fixes so content, SEO, and dev teams can work from one QA pass.
Best results come from pasting the exact HTML version you plan to ship, including the full <head> and main content sections.
Best for
- Landing page refreshes before deploy
- Blog and content QA before publishing
- Service pages with weak rankings or CTR
- Template checks for CMS-generated pages
What this tool does not do
This analyzer reviews pasted HTML only. It does not crawl a live URL, measure Core Web Vitals, replace Search Console, or diagnose index coverage across the whole site.
What this SEO analyzer checks
The report is designed for fast on-page QA, so it balances metadata, structure, technical setup, link quality, and media coverage instead of relying on one shallow score.
Metadata
Title length, meta description coverage, Open Graph, Twitter card, and keyword placement.
Content structure
H1/H2/H3 hierarchy, body depth, and whether the target keyword appears naturally in core locations.
Indexability
Canonical URL, robots directives, html lang, viewport, and JSON-LD presence for cleaner technical setup.
Links
Internal links, external links, and insecure http references that weaken trust or crawl flow.
Media and accessibility
Image count and alt-text coverage so important visuals are not left unlabelled.
Paste the full document when possible so title, canonical, robots, social tags, and schema checks stay accurate.
Priority Fixes
Heading Outline
No headings detected.
Extracted Metrics
All Checks
How to interpret the result
- Fix the highest-weight warnings and failures first because they move the score fastest.
- Treat title, description, H1, and canonical issues as core pre-publish blockers for important pages.
- Use the heading outline to catch duplicate or empty sections before content goes live.
- Pair this report with live crawl and Search Console data when the page is already indexed.

About Seo Analyzer
Audit pasted HTML for titles, descriptions, headings, links, schema, alt text, and keyword placement before publishing.
An SEO page can look acceptable in the browser and still underperform because the actual HTML is weak in places search engines care about. This tool is built for that gap. Instead of waiting for a full crawl or a delayed search report, you can paste the exact markup and review title length, meta description coverage, heading structure, canonical setup, robots directives, schema presence, internal links, image alt coverage, and keyword placement in one pass. It is especially useful for landing pages, blog posts, service pages, and CMS templates where teams want a fast quality-control check before publishing or during a content refresh. Because the output is weighted and easy to export, the report is practical for founders, content writers, SEOs, and developers who need the same page-level action list. Seo Analyzer helps users finish ai tasks with less friction and better consistency. Seo Analyzer helps users finish ai tasks with less friction and better consistency.

When to choose this tool
Choose SEO Analyzer when you need a fast on-page HTML review with actionable fixes before or right after publishing. It is stronger than manual spot-checking because it measures markup and visible content together, but it does not replace live crawl tools, Search Console, or page-speed testing. In practical workflows, this tool works best as the quick QA layer before deeper SEO validation.
Frequently asked questions
Does this SEO analyzer audit a live URL automatically?
No. It analyzes the HTML you paste, which makes it useful for staged pages, drafts, and pre-publish QA.
What should I paste for the most accurate SEO report?
Paste the full HTML document, especially the head tags and the main body content, so metadata and structure checks stay complete.
Can I use this tool before publishing a page?
Yes. That is one of the best use cases because you can audit staged or exported markup before the page goes live.

Yes. The audit covers those signals along with links, images, robots directives, canonical tags, and keyword placement.
Can this help me improve internal links and image alt text?
Yes. The report counts internal links, flags insecure links, and measures image alt-text coverage so those gaps are easier to fix.

No. It is a fast page-level QA tool. Use it with live crawl and Search Console data when you need deeper or sitewide SEO analysis.
