Heading Structure Checker
Heading Structure Checker analyzes pasted HTML heading markup (H1–H6) to identify structural SEO and accessibility problems in seconds. It counts each heading level, flags missing or multiple H1s, detects skipped hierarchy jumps, catches empty headings, and surfaces duplicate heading text. This solves a core content-quality pain point where pages look visually fine but carry semantic heading issues that weaken discoverability and usility. The tool returns a clear structure score and issue list for immediate fixes. A sample input demonstrates real-world mistakes quickly. For premium use, an optional AI Assistant produces a prioritized remediation plan focused on heading hierarchy, clarity, and intent alignment. AI processing is backend-executed and manually triggered while core analysis remains fast and stateless.

Hreflang Checker
Hreflang Checker validates rel="alternate" hreflang markup from pasted HTML to surface duplicates, invalid codes, and missing x-default in seconds. You paste page HTML, run the check, and receive a clear issue list with a practical score so content and technical teams can fix international targeting problems quickly. This solves a frequent multi-language SEO pain point where small markup mistakes cause misaligned search results or cannibalization across locales. A sample input shows proper formatting. For premium users, an optional AI Assistant generates a prioritized remediation plan focused on deduplication, defaults, and standards alignment, executed on the backend and triggered manually.

Image Alt Tag Checker
Image Alt Tag Checker helps you quickly evaluate the quality and completeness of ALT text across your HTML. Paste any snippet or block of HTML containing <img> tags and the tool will parse each image, detect whether the alt attribute is missing or empty, flag generic or unhelpful phrases (such as “image”, “photo”, or “logo”), and identify duplicate ALT values that may harm accessibility and dilute SEO relevance. It returns a concise list of images with their ALT text, a practical issue list, and a simple 0–100 score that reflects overall health. The design encourages clear, descriptive ALT text that communicates image purpose and content without redundancy. The tool is fast, stateless, and ideal for pre‑publish checks and audits. An optional AI Assistant (manual trigger) generates a short, prioritized plan focused on clarity, deduplication, and appropriate empty ALT usage.

On-Page SEO Checker
On-Page SEO Checker helps teams evaluate core on-page optimization factors across many URLs in one workflow. You can paste rows in url|titleLength|metaDescriptionLength|h1Count|wordCount|keywordInTitle|keywordInH1|internalLinks format to generate a weighted quality score and classify pages into good, needs-improvement, or poor categories. This solves a frequent technical SEO bottleneck where metadata, heading structure, content depth, and internal linking quality are audited inconsistently across large content libraries. The tool returns prioritized low-score URLs for remediation planning and supports optional lightweight crawl hints for canonical, noindex, and structured-data context. Its must-have feature is bulk on-page quality scoring with URL-level prioritization. A Sample Input button enables fast onboarding and QA. For premium workflows, an optional AI Assistant converts quality distribution into an execution roadmap for editorial and technical teams.
