See Your Websiteโs SEO Health Clearly
The checker organises findings into clear categories, highlights the most important issues and explains what should be reviewed first.
What Does the Free SEO Checker Analyse?
The checker reviews the page you enter across technical, on-page, content, link, image, schema, accessibility and security signals. Findings are then organised into clear priorities so you can see what needs attention first.

What Does Your SEO Score Actually Mean?
The SEO score summarises the page-level checks included in the report. It helps you understand overall website health quickly, but the individual findings remain more important than the final number alone.
Excellent SEO Foundation
The page passes most of the available checks and shows no major accessibility, indexation or on-page weaknesses. Remaining findings are usually refinements rather than urgent problems.
Good, With Clear Opportunities
The page has a generally healthy structure but contains several issues that may weaken search presentation, accessibility, content clarity or technical consistency.
Improvement Recommended
The page may have a workable base, but multiple technical or on-page findings deserve investigation. Address high-priority issues before spending time on smaller optimisation details.
Significant SEO Work Required
The page contains several weaknesses or one or more serious issues that may affect crawling, indexation, usability or relevance. A wider manual review may be appropriate.
Errors
Important missing, inaccessible or conflicting signals that may require prompt technical or on-page investigation.
Warnings
Conditions that are not always harmful but may weaken clarity, usability, crawling or search presentation.
Opportunities
Additional improvements that may strengthen relevance, internal structure, accessibility or content quality.
Passed Checks
Signals the checker detected successfully, helping you understand which parts of the page already have a suitable foundation.
Use the Score to Prioritise Improvements, Not to Replace SEO Judgement
Start with the highest-impact findings, confirm the issue in context and rescan the page after making changes. When a problem affects multiple URLs, consider a full SEO audit rather than reviewing each page individually.
How Is the SEO Score Calculated?
The checker combines multiple page-level categories into one diagnostic score. Higher-impact technical and content signals carry more weight than minor enhancements, helping the final result reflect the relative importance of each finding.
Weighted SEO Health Calculation
A serious indexation or accessibility issue can influence the result more than a minor optional tag. This prevents low-impact recommendations from carrying the same weight as findings that may affect whether a page can be crawled, understood or used properly.
Weighted Categories
Technical and content categories contribute more to the total score than smaller optional enhancements.
Severity-Based Deductions
Critical errors, warnings and opportunities receive different deductions according to their likely significance.
Positive Signal Recognition
Passed checks show which page elements are present and configured without an obvious initial problem.
Context Still Matters
Automated weighting supports prioritisation, but important changes should still be reviewed against page purpose and search intent.
Transparent Scoring Helps You Understand Why the Result Changed
Scan the same URL after implementing improvements to compare the updated score, issue counts and category performance. For wider website problems, use the checker alongside a professional SEO audit.
What Does Each SEO Report Section Mean?
Each report category focuses on a different part of page health. Understanding the purpose of each section helps you separate urgent technical concerns from content, accessibility and optimisation opportunities.
Executive Summary
Provides the quickest overview of page health, the overall score, strongest category, highest-priority issue and estimated effort required to address the main findings.
- Overall score and health grade
- Biggest detected issue
- Strongest report category
- Estimated implementation effort
Technical SEO
Reviews whether the page can be accessed, interpreted and indexed correctly. Technical issues often deserve early attention because they can affect the page before content quality is considered.
- HTTP response and HTTPS
- Canonical and robots directives
- Mobile viewport and charset
- robots.txt and sitemap signals
On-Page and Content
Examines how clearly the page communicates its topic, purpose and hierarchy through metadata, headings, visible copy and supporting page elements.
- Meta title and description
- H1 and heading hierarchy
- Visible word count
- Keyword placement where supplied
Links and Structure
Reviews how the page connects with other website content and external resources. Internal links support navigation, page relationships and crawl flow.
- Internal and external links
- Anchor text observations
- Nofollow signals
- Broken or inaccessible destinations
Images and Accessibility
Highlights image and interface conditions that may affect accessibility, image search, layout stability and usability for visitors using assistive technology.
- Missing image alt text
- Image dimensions and lazy loading
- Form labels and empty links
- HTML language declaration
Security and Performance
Reviews selected security and performance conditions, including HTTPS, mixed content, security headers, SSL details and optional PageSpeed data.
- HTTPS and mixed-content checks
- Security response headers
- SSL certificate information
- Core Web Vitals where available
Schema and Social Metadata
Detects structured data and social-sharing tags that provide additional page context to search engines and external platforms.
- Detected JSON-LD schema types
- Open Graph metadata
- Twitter/X card tags
- Organisation and breadcrumb signals
Recommendations and Action Plan
Converts detected issues into an ordered list of recommended actions with priority, likely impact, difficulty and estimated implementation time.
- Priority level
- Why the finding matters
- Suggested fix
- Estimated effort and timing
Confirm the Page Is Accessible
Begin with the response status, HTTPS, robots directives and canonical signals.
Review Topic and Metadata Clarity
Check whether the title, description, H1 and content clearly match the pageโs intended purpose.
Inspect Supporting Page Signals
Review links, images, accessibility, schema and social metadata for missing or weak supporting elements.
Implement and Rescan
Apply suitable fixes, test the page and run the checker again to compare the updated result.
Use Each Report Section to Build a Practical Optimisation Plan
Address technical barriers first, then improve page relevance, structure, accessibility and supporting signals. When the same issue affects multiple URLs, a full SEO audit can provide a more efficient sitewide roadmap.
Common SEO Problems the Website Checker Can Detect
The checker identifies common page-level weaknesses and explains why each finding may matter. Some issues can affect crawling or indexation, while others influence search presentation, accessibility or content clarity.
Noindex Directive Detected
A noindex directive can prevent the scanned page from appearing in search results, even when the content and links are otherwise well optimised.
Conflicting Canonical URL
A canonical tag pointing to a different or incorrect URL may send confusing consolidation signals and affect which page search engines choose to index.
Missing or Weak Meta Title
The title may be absent, overly short, excessively long or too generic to communicate the page topic effectively in search results.
Missing H1 or Weak Heading Structure
A missing primary heading or disorganised H2 and H3 hierarchy can make page structure less clear to users and search engines.
Images Missing Alternative Text
Relevant images without useful alt attributes can weaken accessibility and reduce the contextual information available to search engines.
Limited Internal Linking
A page with few relevant internal links may be harder to discover and may not clearly show its relationship with supporting content or commercial pages.
Structured Data Not Detected
The page may not include JSON-LD markup that gives search engines additional structured context about its content or organisation.
Missing Security Headers
Important browser security headers may be absent, leaving fewer protections against framing, MIME sniffing or insecure transport behaviour.
Slow PageSpeed or Core Web Vitals
Optional PageSpeed data may reveal slow loading, layout movement or interaction delays that can affect usability on mobile and desktop devices.
Prioritise Problems by Risk and Business Importance
A missing social tag should not receive the same attention as a noindex directive or broken canonical. Resolve issues that affect accessibility, crawling and indexation before working through lower-impact enhancements.
Detecting an Issue Is Only the First Step
Confirm each finding within the page template and wider website before making changes. When several pages share the same problem, a professional SEO audit can identify the underlying sitewide cause more efficiently.

Common Questions About the Free SEO Checker
These answers explain what the checker can analyse, how the report should be interpreted and when a page-level scan should be supported by a wider professional SEO audit.
01 What is a free SEO checker?
A free SEO checker is a diagnostic tool that analyses a public webpage for common technical, on-page, content, link, image, schema, accessibility and security signals. It then organises the findings into a score and prioritised report.
02 Is the GuestPost.UK SEO checker really free?
Yes. The checker provides a free initial page-level report without requiring a paid subscription or mandatory account registration. Public usage limits may apply to protect the website from automated abuse.
03 Does the checker analyse the whole website?
The checker primarily analyses the exact URL entered. It may review selected domain-level signals such as robots.txt, XML sitemap, DNS and SSL information, but it does not replace a full sitewide crawler or professional SEO audit.
04 Can the SEO score predict Google rankings?
No. The score summarises the checks included in this tool. It is not a Google ranking factor and cannot guarantee a specific search position. Rankings depend on relevance, competition, authority, user intent and many wider signals.
05 Which technical SEO issues can the checker detect?
The report can review HTTP status, HTTPS, canonical tags, robots directives, mobile viewport, charset, robots.txt, sitemap availability, selected security headers, mixed content and other detectable page-level conditions.
06 Does it check titles, descriptions and headings?
Yes. The checker reviews the meta title, meta description, H1, supporting headings and selected content signals. It can also compare an optional target keyword with relevant page elements.
07 Can it find missing image alt text?
Yes. The report can count images, identify missing or empty alternative-text attributes and review selected image attributes such as lazy loading, width, height and modern image formats.
08 Does the checker test website speed?
Where available, the checker can load Google PageSpeed Insights data separately from the core report. This may include mobile or desktop performance scores and metrics such as LCP, CLS, INP, FCP and TBT.
09 Can the tool show exact website traffic?
No public checker can know exact traffic without access to private first-party data. Real organic clicks normally come from Google Search Console, while sessions and conversions require analytics access.
10 Why do different SEO tools give different scores?
Every tool uses its own checks, thresholds and category weightings. One checker may emphasise performance, while another gives greater weight to metadata or technical signals. The individual findings are more useful than comparing final scores alone.
11 Will the checker fix SEO issues automatically?
No. The checker identifies potential issues and provides recommended actions. Changes should be reviewed carefully, especially when they involve redirects, canonicals, robots directives, server settings or shared website templates.
12 How often should I run an SEO check?
Important pages can be checked before publication, after substantial optimisation, following a redesign or migration, and whenever an unexpected ranking or indexation issue appears.
13 Is the report suitable for clients or internal teams?
Yes. The report includes print, PDF and export options that can support internal reviews, implementation notes and early client discussions. Automated findings should still be verified before presenting them as confirmed sitewide problems.
14 When should I choose a professional SEO audit?
Choose a professional audit when you need sitewide crawling, competitor analysis, keyword mapping, migration support, Search Console interpretation or a prioritised roadmap that covers multiple templates and URLs.
Still Unsure What a Finding Means?
Share the affected URL and the wider SEO concern when you need help interpreting a result, investigating a sitewide pattern or planning the next stage of optimisation.
Turn Your SEO Checker Results Into Measurable Website Improvements
Use the free SEO checker to identify page-level weaknesses, prioritise the most important findings and confirm whether recent changes improved the report. When the same problems affect multiple pages, move from automated diagnosis to a complete professional SEO strategy.
