Frequently asked questions
What is on-page search engine optimisation?
On-Page SEO is the practice of optimising the content, structure, and on-page elements of individual webpages so search engines can understand their relevance, quality, and intent. It focuses on what’s on the page—including text, media, semantic HTML, metadata, and user experience elements. The audit evaluates clarity, keyword alignment, content relevance, engagement signals, and how effectively on-page elements support stronger visibility in both traditional and generative search results.
What is content quality & relevance?
This ensures each page provides accurate, helpful, and comprehensive information aligned with user intent. Strong on-page content includes a clear topical focus, depth and accuracy, original, user-first insights, and semantic keywords and contextual entities.
What is keyword optimisation?
This ensures primary and secondary keywords appear naturally in critical on-page locations, including the title tag, meta description, headings (H1–H3), body content, image alt text, and URL slug.
What are HTML tags & semantic structure?
These help search engines interpret your page hierarchy, meaning, and content relationships — including proper heading structure, semantic HTML aligned with schema where useful, descriptive, context-rich anchor text, and accessible alt attributes.
What is internal linking?
Internal linking strengthens connections between pages and improves overall discoverability. Effective internal linking guides users to related or deeper content, distributes PageRank strategically, and highlights priority or cornerstone pages.
What are user experience & engagement signals?
These enhance how visitors interact with your page, indirectly supporting stronger rankings — including readable layout and typography, low bounce rates through meaningful content, high engagement (time on page, interactions, scroll depth), and mobile-friendly formatting and responsive design.
What is image & media optimisation?
This ensures media loads efficiently and enhances understanding, including descriptive alt text, compressed, lightweight image files, responsive media formats, and relevant and contextual visuals.
What are meta tags?
Meta tags help search engines and users understand the page before visiting it, including the title tag (a ranking factor), meta description (a CTR factor), and Open Graph & Twitter Card tags.
What is content freshness?
This supports relevance and ranking potential by ensuring information stays current — updating outdated or inaccurate facts, adding new insights, examples, or data, and refreshing visuals and supporting media.
Who should use this tool?
This tool is especially useful for SEO professionals auditing on-page content, accessibility reviewers and auditors, content strategists and copywriters, developers improving semantic HTML, agencies performing fast content audits, and site owners seeking clearer, more effective pages.
What does this tool analyse?
This tool analyses content structure and heading hierarchy (H1–H6), keyword alignment and on-page copy effectiveness, internal linking and contextual navigation, accessibility and semantic HTML usage, media clarity, usefulness, and messaging support, and body-level SEO signals and structured data opportunities.
What does this tool not analyse?
This tool does not analyse <head> metadata or technical SEO settings, page performance or loading speed, JavaScript execution or rendered DOM output, security configuration or analytics data, or rankings, backlinks, or traffic metrics.
What are the usage limits?
To ensure fair access and reliable performance, the tool may pause during periods of high traffic, the page must be publicly accessible on the web, and it must contain a proper <body> tag. If a page can’t be fetched or doesn’t include a valid body element, you’ll see a clear error message explaining the issue.
Does this tool make changes to my website?
No. This tool only analyses your page content and provides recommendations. It does not modify or inject any code.
Why is my page not analysed?
Common causes include the page not being publicly accessible, automated requests being blocked by firewalls or bot protection, the site requiring authentication, cookies, or an active session, geographic or IP-based restrictions preventing access, or the server returning incomplete or invalid HTML.
Is my data stored or logged?
No content is stored long-term. URLs are processed temporarily to generate the analysis and then discarded.
Why are scripts or styling ignored during analysis?
Non-content elements are excluded so the analysis can focus on structure, semantics, clarity, accessibility, and copy effectiveness, rather than visual presentation or behaviour.
What AI model is used for analysis?
This tool uses GPT-4o-mini, a lightweight and efficient model designed to deliver fast, high-quality audits with minimal latency.
Can I analyse private or staging websites?
If the page is publicly accessible, then the tool should work.
