What Does This SEO Checker Analyse?
Our free on-page SEO checker fetches a URL in real time and evaluates the HTML elements that directly influence how Google crawls and ranks your page:
- Title tag — presence, character length (50–60 ideal), and uniqueness
- Meta description — presence and length (Google displays up to ~155 characters)
- H1 heading — every page needs exactly one H1 matching the page topic
- Canonical tag — prevents duplicate content penalties across similar URLs
- Meta robots — noindex/nofollow directives that control crawling and indexing
- Open Graph tags — og:title, og:description, og:image for rich social sharing
- Schema markup — JSON-LD structured data types detected on the page
- Images without alt text — missing alt attributes hurt accessibility and image search
How to Interpret Your SEO Score
- 80–100: Well-optimised. Focus on off-page factors like backlinks.
- 50–79: Moderate issues. Fixing warnings will improve CTR and crawlability.
- 0–49: Critical problems. Address errors before any other optimisation work.
Common On-Page SEO Fixes
Title too long (>60 chars): Trim to fit Google's ~580px display width. Front-load your target keyword.
Missing meta description: Write 140–155 characters with a clear call to action. It won't directly boost rankings but improves click-through rate from SERPs.
No canonical tag: Add a self-referencing canonical in every page's head. Critical for paginated pages and URLs with parameters.
No H1: Every page needs exactly one H1 that contains your primary keyword. It's the strongest on-page relevance signal after the title tag.
Images missing alt text: Add descriptive alt attributes to every meaningful image. Keep them under 125 characters — descriptive, not keyword-stuffed.
