How to Use the SEO Audit Checker
Using the tool is simple.
Enter the full webpage URL, including https://, and click Check SEO.
For example:
https://example.com/
The tool fetches the publicly available HTML of the page and analyses important SEO elements. Within a few seconds, you will receive an easy-to-read audit report.
You can use the results to identify common issues before making changes to your website.
Why Run an SEO Audit?
A webpage can look perfectly fine to visitors while still having technical or on-page SEO problems.
For example, a page may have:
- no title tag
- a missing meta description
- multiple H1 headings
- missing image ALT text
- incorrect canonical tags
- a noindex directive
- no structured data
- missing robots.txt
- no detectable sitemap
These issues do not automatically mean a page cannot rank, but they may make it harder for search engines to properly understand, crawl or display the page.
Running a quick website SEO audit helps you identify these problems before they become bigger issues.
Check Your Page Title and Meta Description
Title tags and meta descriptions are among the first elements website owners usually review during an on-page SEO audit.
A useful title should clearly describe the main topic of the page without being unnecessarily long or repetitive.
The meta description should provide a useful summary of the page and encourage searchers to click when it appears in search results.
Our SEO checker tool detects whether these elements are present and displays their approximate character length so you can review them easily.
Analyze H1, H2 and H3 Headings
Headings help organize content for both users and search engines.
The SEO Audit Checker identifies the number of H1, H2 and H3 headings found on the page.
A clear heading structure makes content easier to scan and can help search engines understand the relationship between different sections of a webpage.
Rather than adding headings simply for SEO, use them to create a logical content structure.
Find Images Missing ALT Text
Image ALT attributes help describe images when they cannot be displayed and can also improve accessibility.
Our audit tool checks the images found in the HTML and reports how many have missing or empty ALT attributes.
Not every decorative image needs keyword-focused ALT text. The goal should be to provide useful descriptions for meaningful images.
Check Canonical Tags
Canonical tags can help search engines understand which version of a URL should be treated as the preferred version when similar or duplicate pages exist.
The tool checks whether a canonical tag has been detected and shows the canonical URL.
If the canonical points to an unexpected URL, it may be worth reviewing the page configuration.
Check Meta Robots and Indexability Signals
A page can sometimes contain directives that prevent search engines from indexing it.
Our tool checks common page-level robots directives and alerts you if a noindex instruction is detected.
It also checks:
- HTTP response status
- HTTPS usage
- robots.txt availability
- canonical tag
These signals can help you understand whether there are obvious technical issues that may affect search engine access.
Important
The tool checks indexability signals, but it does not claim that a page is definitely indexed by Google.
Actual Google indexing status is different from checking whether a page appears technically eligible for indexing.
Detect Schema Markup
Structured data helps search engines understand certain types of information on a webpage.
The audit checker looks for JSON-LD structured data and identifies schema types where possible, such as:
- Organization
- LocalBusiness
- Article
- Product
- FAQPage
- BreadcrumbList
- WebSite
Having schema does not guarantee rich results, but properly implemented structured data can provide search engines with clearer information about page content.
Check Open Graph and Social Meta Tags
SEO and social sharing often overlap.
The checker reviews common Open Graph tags including:
- og:title
- og:description
- og:image
It can also detect common Twitter/X card metadata.
These tags can improve how your webpage appears when shared on social media platforms.
Check robots.txt and XML Sitemap
A technical SEO audit should also review whether search engine crawlers can discover important website resources.
The tool checks common locations for:
robots.txt
https://example.com/robots.txt
and XML sitemaps such as:
https://example.com/sitemap.xml
https://example.com/sitemap_index.xml
https://example.com/wp-sitemap.xml
A valid XML sitemap can help search engines discover important URLs, while robots.txt provides crawling instructions.
Check robots.txt and XML Sitemap
A technical SEO audit should also review whether search engine crawlers can discover important website resources.
The tool checks common locations for:
robots.txt
https://example.com/robots.txt
and XML sitemaps such as:
https://example.com/sitemap.xml
https://example.com/sitemap_index.xml
https://example.com/wp-sitemap.xml
A valid XML sitemap can help search engines discover important URLs, while robots.txt provides crawling instructions.
What Does the SEO Score Mean?
The Antops SEO Audit Checker may display an overall score out of 100.
This score is based on the checks performed by the tool and is intended to make the report easier to understand.
It is not a Google ranking score.
A page with a high audit score is not guaranteed to rank higher than another page. Search rankings depend on many additional factors, including content quality, relevance, competition, backlinks, authority, search intent and user experience.
Use the score as a diagnostic guide rather than a ranking prediction.
Who Can Use This SEO Checker?
The tool can be useful for:
- Website owners
- SEO professionals
- Digital marketing agencies
- Bloggers
- Ecommerce businesses
- Developers
- WordPress users
- Small businesses
- Freelancers
- Students learning SEO
You can also use it when reviewing a new webpage before publishing major SEO changes.
Free SEO Checker Without a Paid SEO Account
Many professional SEO platforms provide powerful data, but not every website owner needs a paid subscription for basic on-page checks.
The Antops tool focuses on information that can be analyzed directly from publicly available webpage data.
This makes it useful for quick audits, troubleshooting and basic technical SEO reviews.
For deeper research such as backlink databases, keyword search volume, competitor rankings or proprietary authority metrics, specialist third-party platforms may still be required.
Frequently Asked Questions
Is the SEO Audit Checker free?
Yes. You can use the Antops SEO Audit Checker to analyze supported public webpages without purchasing a paid SEO API subscription.
Does the tool check Google rankings?
No. This tool analyses on-page and technical SEO elements. It does not provide keyword ranking positions.
Can it tell whether my website is indexed by Google?
It can identify common indexability signals such as noindex, HTTP status and robots settings, but it cannot guarantee whether Google has indexed a specific page.
Does the SEO score affect my Google ranking?
No. The score is created by the audit tool as a simple way to summarize the checks performed. Google does not use this Antops score.
Why can’t the tool analyze some websites?
Some websites block automated server requests through firewalls, security plugins, CDN settings or bot protection. In those cases, the tool may not be able to fetch the page.
Can I audit any website?
You can check publicly accessible webpages that allow the tool to retrieve their HTML.
Does the tool check backlinks?
No. Accurate backlink data generally requires access to a large external link database. This checker focuses on on-page and basic technical SEO checks.
