🦈 BrandorAI Guide: FREE SEO & Website Performance Tool (Lighthouse)

🌊 What is Lighthouse?

Google Lighthouse is a free, open-source auditing tool built right into Chrome. It’s designed to help website owners, developers, and marketers analyze site speed, SEO readiness, accessibility, and overall performance.

Unlike other tools that give you only surface-level data, Lighthouse runs an in-depth audit and produces a report card with scores (0–100) across multiple categories.

Think of Lighthouse as your underwater sonar system — scanning your website to detect hidden problems that could be slowing you down or costing you rankings.

⚡ Why Lighthouse Matters for Your SEO

Google has confirmed that page experience is a ranking factor, and Lighthouse is Google’s own tool for measuring that experience. Here’s why it’s important:

  • Core Web Vitals: Lighthouse checks Google’s speed and user experience metrics directly.

  • SEO Basics: It evaluates whether your site follows best practices for search engine optimization.

  • Accessibility: It ensures your site can be used by everyone — including those with disabilities.

  • Best Practices: Identifies outdated or insecure code and highlights areas for improvement.

🦈 BrandorAI Shark Tip: “If Google uses these metrics to judge your site, why wouldn’t you? Lighthouse is like a sneak peek into how Google views your digital presence.”

🛠️ How to Use Lighthouse (Step-by-Step)

Method 1: Chrome DevTools

  1. Open your website in Google Chrome.

  2. Right-click anywhere on the page → Click Inspect.

  3. In the top menu, click on the Lighthouse tab.

  4. Choose the categories you want to audit (Performance, SEO, Best Practices, Accessibility, PWA).

  5. Select device type (Mobile or Desktop).

  6. Hit Analyze page load.

  7. Wait a few seconds — Lighthouse will generate a full report with scores and recommendations.

Method 2: Online Tool

📊 Understanding Your Lighthouse Scores

Each audit gives you a score between 0–100 in these categories:

  • Performance: How fast your page loads and responds.

  • Accessibility: Can all users (including screen readers) navigate your site?

  • Best Practices: Is your site secure and using modern code?

  • SEO: Are you meeting Google’s SEO basics (titles, alt text, meta tags)?

  • Progressive Web App (PWA): Checks if your site can function like an app (optional).

🦈 BrandorAI Shark Tip: “Don’t panic if you’re not at 100. Even major brands often score in the 70s–80s. The goal is steady improvement, not perfection.”
