Content Inventory Generator - Online Count Words & Headings

A Content Inventory is a systematic audit of all content elements on a webpage or across a website. It typically catalogs headings, word counts, media assets, metadata, and structural elements. Content strategists and SEO professionals use inventories to identify gaps, optimize structure, and ensure content aligns with user intent. This tool focuses on the single-page analysis aspect — counting words, headings, and keyword density to give you a quick health check of any piece of content.

Word count correlates with content depth — comprehensive articles (typically 1,500–2,500+ words) tend to rank better for competitive keywords. However, quality matters more than quantity. Heading structure (H1–H6) helps search engines understand your content hierarchy. A well-organized heading structure improves crawlability, accessibility, and user experience. Google uses headings as contextual signals to determine what your page is about and how information is organized.

According to Google's SEO best practices and the HTML5 specification, a page should have exactly one H1 tag that represents the main topic. While Google has stated they can handle multiple H1s (especially in HTML5 sections), using a single, clear H1 eliminates ambiguity and is widely considered best practice. This tool will flag if your content has 0 or multiple H1 tags so you can fix the issue immediately.

Keyword density is the percentage of times a keyword appears relative to the total word count. While it was once a major ranking factor, modern search engines focus more on topical relevance and natural language. A healthy keyword density typically falls between 0.5% and 2%. This tool helps you identify which terms appear most frequently so you can ensure your content naturally covers the intended topic without keyword stuffing.

The ideal reading time depends on your content type and audience. For blog posts, 5–8 minutes (1,200–2,000 words) is a sweet spot for engagement. Landing pages should be scannable in 1–3 minutes. In-depth guides may run 10–20 minutes. This tool calculates reading time at 225 words per minute, the average reading speed for English-language adults reading online content. Use this as a guideline, not a strict rule.

Step 1: Copy the full HTML source of your webpage (right-click → View Page Source → Ctrl+A → Ctrl+C) or paste plain text content.
Step 2: Paste it into the input box above. The tool auto-detects HTML vs. plain text.
Step 3: Review the stats cards for words, characters, headings, paragraphs, sentences, and reading time.
Step 4: Check the heading hierarchy table — ensure you have exactly 1 H1 and logical nesting.
Step 5: Review keyword density to confirm your content covers the intended topics naturally.
Step 6: Use "Copy Report" to save or share your analysis.

Common mistakes include: ① Skipping heading levels (e.g., jumping from H2 to H4 without an H3) — this confuses screen readers and search engines. ② Using headings for styling instead of structure — use CSS for visual formatting, not heading tags. ③ Multiple H1 tags diluting the main topic signal. ④ Empty or overly generic headings like "Section 1" or "More Info." ⑤ Excessively long headings that read like paragraphs. Aim for descriptive, concise headings that form a logical outline of your content.

The URL fetch feature attempts to retrieve content directly, but most websites block cross-origin requests (CORS policy) for security reasons. If the fetch fails, simply view the page source (Ctrl+U or Cmd+Option+U) and paste the HTML into the tool. This actually gives you a more complete analysis since you're seeing the raw HTML that search engines crawl. For dynamic JavaScript-rendered content, use your browser's "Inspect Element" to copy the rendered DOM.

Not directly — Google has confirmed that word count is not a direct ranking factor. However, longer, well-researched content tends to attract more backlinks, cover topics more comprehensively, and satisfy user intent better — all of which indirectly boost rankings. Focus on covering your topic thoroughly rather than hitting an arbitrary word count. A 800-word article that perfectly answers a query can outrank a 3,000-word fluff piece.

A Content Inventory is a quantitative catalog — it lists what content exists (URLs, titles, word counts, headings, media types). A Content Audit goes further by evaluating quality — assessing performance metrics, relevance, accuracy, and conversion rates. Think of the inventory as a spreadsheet of facts, and the audit as the analysis that tells you what to keep, improve, or remove. This tool gives you the inventory data for a single page as the foundation for deeper auditing.
