Website SEO Analyzer
Get a comprehensive SEO audit of any webpage in seconds — identify and fix critical SEO issues.
What is Website SEO Analyzer?
An SEO analyzer examines a webpage against dozens of on-page SEO factors and reports back what is working, what is broken, and what can be improved. Modern SEO involves far more than keywords — it encompasses technical factors (page speed, mobile responsiveness, structured data), content factors (heading hierarchy, content length, keyword usage), link factors (internal linking, outbound links, broken links), and meta factors (title tags, descriptions, canonical tags, Open Graph). Manually checking all these factors for every page is time-consuming and error-prone. This tool automates the audit: paste any URL and receive a structured report covering every significant on-page SEO element, with actionable recommendations and severity ratings (critical, warning, info) so you know which issues to fix first.
How to Use Website SEO Analyzer
- 1
Enter a Page URL
Paste any live webpage URL. The tool fetches the page content, reads the HTML, and analyses all on-page SEO elements including meta tags, headings, links, and images.
- 2
Review the Audit Report
Receive a structured report covering 30+ SEO factors, each rated as Pass, Warning, or Critical. Critical issues (missing title, no meta description) are listed first.
- 3
Fix Issues with Recommendations
Each flagged issue includes a plain-English explanation and a specific fix recommendation — no SEO expertise required to act on the results.
Use Cases
Pre-Publishing Content Checklist
Before publishing any blog post or landing page, run it through the SEO analyzer to catch quick wins: Is the H1 set? Is the meta description within length? Do all images have alt text? Addressing these issues pre-publish is far easier than hunting them down post-launch across dozens of pages.
Competitor Page Analysis
Analyze your competitors' top-ranking pages to understand their on-page SEO structure — what keywords appear in their H1 and H2s, how they structure their content, what schema markup they use. Use these insights to inform your own content strategy and identify gaps your pages can fill.
Site Audit for New Clients
SEO agencies run this tool against every key page of a new client's site during onboarding. The structured audit report serves as the basis for a prioritised SEO roadmap, showing the client exactly which issues need fixing and in what order.
Features
Meta Tag Analysis
Checks title tag (presence, length, keyword placement), meta description (presence, length, uniqueness flags), and canonical tag configuration.
Heading Structure Audit
Verifies that your page has exactly one H1, that headings follow a logical hierarchy (H1→H2→H3), and flags missing or duplicated heading levels.
Image SEO Check
Lists all images on the page, flags those missing alt text (critical for accessibility and image SEO), and checks for oversized images that may impact load time.
Link Analysis
Counts internal and external links, identifies broken links returning 404 errors, and checks for proper use of rel="nofollow" and rel="noopener" attributes.
Schema Detection
Detects JSON-LD, Microdata, and RDFa structured data on the page, listing detected schema types to confirm rich snippet eligibility.
Frequently Asked Questions
The single most impactful factor is the page title tag — it directly influences click-through rates in search results and is one of Google's strongest ranking signals for relevance. A missing or duplicate title tag is the highest-priority critical issue. Close behind it: meta description (affects clicks, not rankings), H1 tag (should contain your primary keyword), and page load speed (a confirmed ranking factor since Google's Core Web Vitals update).
Google Search Console reports on your site's performance from Google's perspective — impressions, clicks, index coverage, Core Web Vitals measured on real users. This tool analyzes your page's HTML structure from an on-page SEO perspective — what's in your meta tags, headings, and structured data. They are complementary: use Search Console for performance data and crawl issues, use this analyzer for on-page content audits. Both are essential for a complete SEO workflow.
The analyzer checks for mobile-related meta tags (viewport tag presence, which is required for mobile responsiveness) and reports on factors that affect mobile experience (page speed, image sizes). However, for a complete mobile SEO assessment, Google's Mobile-Friendly Test and PageSpeed Insights (which provides separate mobile and desktop scores) are the authoritative tools. This analyzer is focused on HTML structure and on-page content factors.
For actively maintained sites, audit key pages (homepage, main service/product pages, top traffic pages) every 1–3 months. Run an audit whenever you make significant changes to a page's content or structure. For new pages, audit before publishing. For e-commerce sites with large catalogs, consider a weekly automated audit of your highest-revenue pages. The goal is to catch regressions early — it's easy for a CMS update or template change to accidentally strip meta tags from hundreds of pages.
