Frequently Asked Questions
What does a URL technical SEO checker inspect?▾
A technical URL checker analyzes whether a specific page can be discovered, crawled, rendered, and indexed by search engines. It verifies the HTTP status code (200 OK vs 3xx/4xx), HTTPS security protocol, self-referencing rel=canonical tag, robots meta directives (noindex/nofollow), Open Graph preview tags, and primary H1 title tags.
Why is a self-referencing canonical tag important?▾
A self-referencing canonical tag explicitly informs search engines that the current URL is the authoritative source version of the content. This prevents duplicate content penalties caused by tracking query parameters, session IDs, and trailing slash variations.
What is the optimal character length for title and meta description tags?▾
Title tags should ideally remain between 50 and 60 characters (approximately 580 pixels) to avoid being truncated on Google mobile and desktop SERPs. Meta descriptions should range between 120 and 155 characters to display complete, compelling summary snippets.
Can this tool check external client websites?▾
Yes. You can test any public URL without creating an account or installing browser extensions.
