Rabail's SEO Toolkit

Overview

I created the SEO Toolkit as an all-in-one, browser-based SEO auditing tool that lets you analyze any webpage's on-page SEO health in seconds — no software installation, no subscriptions, no API keys. Just paste a URL or enter it directly and get an instant, actionable breakdown of what's working and what needs fixing.

As someone who builds websites professionally, I was frustrated by tools that either cost hundreds per month or required complicated setups. The SEO Toolkit solves that by running entirely in your browser using vanilla HTML, CSS, and JavaScript, making it fast, private, and completely free to use.

Key Features

• Meta Tag Analysis — Checks your title tag length, meta description, Open Graph tags, and Twitter cards against Google's latest recommendations.
• Heading Structure Audit — Verifies proper H1-H6 hierarchy, flags missing H1 tags, and detects heading order violations.
• Alt Text Scanner — Scans every image on the page and reports which ones are missing descriptive alt attributes for accessibility and image SEO.
• Broken Link Detector — Crawls all anchor tags to identify dead links that could hurt your search rankings and user experience.
• Keyword Density Analyzer — Calculates word frequency across the page content to help you optimize without over-stuffing keywords.

Tech Stack

Built entirely with HTML, CSS, and vanilla JavaScript. No frameworks, no build tools — just clean, fast, dependency-free code that runs in any modern browser. DOM parsing and analysis happen client-side for maximum privacy.

Problem it solves

Professional SEO audit tools are expensive and complex. This toolkit gives developers and content creators a free, instant way to audit their on-page SEO directly in the browser.

How it was built

Built with vanilla HTML, CSS, and JavaScript — no frameworks or dependencies. All analysis runs client-side for speed and privacy.
