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.

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.
