The Content Checker evaluates your page content across readability, SEO signals and duplicate content risk. It checks: keyword density and placement (title, H1, first 100 words), content length versus competitor pages, reading level (Flesch-Kincaid), heading structure (H1→H2→H3 hierarchy), internal link count, and whether the page has thin or duplicate content compared to other pages on your site.
Content length should match search intent, not a fixed number. Informational queries ('how to do X') are typically best served by comprehensive guides of 1,500–3,000 words. Transactional queries ('buy X') convert better with concise, focused pages of 300–800 words. Check the average word count of pages currently ranking on page 1 for your target keyword and aim to match or exceed it.
Thin content is a page with minimal value to users — typically under 300 words, duplicate of other pages, auto-generated text or content that doesn't answer the searcher's query. Google's Panda algorithm targets thin content and can suppress or de-index affected pages. The fix is to either substantially expand the content or consolidate thin pages using 301 redirects to more authoritative versions.
To appear in AI overview and generative search answers, structure your content with clear question-and-answer sections (use H2/H3 headings as questions), add FAQPage schema markup, write in plain language with short sentences, define key terms early in the page, and provide specific factual answers rather than vague generalisations. AI systems extract well-structured, authoritative, factual content.
