HTML Link & Heading Extractor
About HTML Tag Counter
The HTML Tag Frequency & Element Distribution Counter analyzes HTML documents to calculate exact usage frequencies for every HTML tag (`<div>`, `<p>`, `<span>`, `<a>`, `<button>`), reporting DOM complexity and semantic tag ratios.
How to Use HTML Tag Counter
Step 1
Paste your HTML source code into the editor.
Step 2
Inspect the tag distribution bar chart and frequency breakdown table.
Step 3
Click "Export CSV" to save the tag audit report.
Practical Use Cases for HTML Tag Counter
Diagnosing "Div Soup" and Semantic Quality
Measure the ratio of non-semantic `<div>` and `<span>` tags against semantic HTML5 tags (`<article>`, `<section>`, `<nav>`, `<header>`).
Auditing DOM Complexity for Web Performance (Lighthouse)
Count total DOM elements to identify excessive DOM nodes that degrade page rendering speed and scroll performance.
Input & Output Examples
Counting Tag Frequencies
`<div><p>Hello</p><p>World</p><a href="#">Link</a></div>`
Total Tags: 4 | `<p>`: 2 (50%) | `<div>`: 1 (25%) | `<a>`: 1 (25%) | Semantic Health: Moderate
Key Features & Performance
- ✓Calculates total element count, unique tag count, and frequency percentages.
- ✓Categorizes tags by: Semantic Structure, Forms, Media, Tables, and Deprecated tags.
- ✓Generates interactive distribution charts and sortable data tables.
- ✓100% Client-Side DOM parser execution.
- ✓1-Click Export CSV report.
Key Terminology & Definitions
DOM Node Count (Lighthouse)
The total number of HTML elements on a page; Google Lighthouse recommends keeping DOM size under 1,400 total nodes.
Div Soup
The anti-pattern of overusing non-semantic `<div>` tags for layout instead of appropriate semantic HTML5 elements.
