SEO Analyzer FAQs

How does this SEO analyzer work? +

This tool analyzes your website directly in your browser using JavaScript. It fetches the HTML of your page and checks for SEO elements like meta tags, headings, images, and links without sending any data to servers.

Is my website data safe? +

Yes! All analysis happens in your browser. We never collect, store, or transmit your website data. Your information remains completely private.

Why can’t I analyze some websites? +

Due to browser security restrictions (CORS policy), you can only analyze websites that allow cross-origin requests. Most public websites work, but some may block external analysis.

What SEO factors does this tool check? +

We check meta tags, heading structure, image ALT attributes, internal/external links, canonical tags, robots directives, Open Graph/Twitter cards, page performance signals, and basic keyword density.

How accurate is this analysis? +

This tool provides a comprehensive on-page SEO analysis based on industry best practices. However, it doesn’t replace professional SEO audits which include technical, off-page, and content quality assessments.
