Analyze Single Web Page for SEO

Single Page Analysis runs a detailed on-page SEO review of one URL - metadata, content, schema, images, and page-level technical signals together - producing a scored breakdown across five categories.

Use this when the user provides a single URL for detailed on-page review, when auditing one page rather than an entire site, or when checking metadata, content, schema, images, and technical signals together.

Checks span: on-page SEO (title tag 50-60 characters with the primary keyword and uniqueness, meta description 150-160 characters, exactly one H1 matching page intent, a logical H2-H6 hierarchy with no skipped levels, a short hyphenated URL with no parameters, sufficient internal links with relevant anchor text, external links to authoritative sources); content quality (word count against page-type minimums, Flesch Reading Ease and grade level, natural 1-3% keyword density with semantic variations, E-E-A-T signals like author bio and first-hand experience markers, publication and update dates); technical elements (canonical tag, meta robots, Open Graph and Twitter Card tags, hreflang for multi-language pages); schema markup (detects all JSON-LD types present, validates required properties, flags missing opportunities, and explicitly never recommends HowTo, which is deprecated, or FAQ, which is now restricted to government/health sites); images (alt text presence and quality, file-size warnings at 200KB and critical flags at 500KB, WebP/AVIF over JPEG/PNG, explicit width/height to prevent CLS, lazy loading below the fold); and Core Web Vitals risk flags inferred from the HTML alone rather than measured directly - oversized hero images or render-blocking resources for LCP, heavy or non-deferred JS for INP, missing image dimensions or injected content for CLS. Output is a per-category score card (On-Page SEO, Content Quality, Technical, Schema, Images, each out of 100) plus issues ranked Critical > High > Medium > Low, specific actionable recommendations, and ready-to-use JSON-LD for any detected schema opportunities.

Optionally pulls live data via DataForSEO MCP tools when available - serp_organic_live_advanced for real SERP positions and backlinks_summary for backlink data and spam scores. It handles three failure modes explicitly: an unreachable URL gets reported as an error rather than guessed at, an authentication-gated page (401/403) prompts a request for rendered HTML or a public URL, and JavaScript-rendered content with an empty HTML body gets flagged as potentially incomplete with a suggestion to supply a browser-rendered snapshot.

Anyone who needs a focused, single-page SEO audit rather than a full-site crawl - covering metadata, content quality, technical tags, schema, and images in one pass with a scored, prioritized report.
