SEO Checker by Creative Nexus

One-click on-page SEO audit: title, meta description, headings, Open Graph, canonical, alt tags and more.

Open a page, click the icon, and you get an instant on-page SEO audit with a score out of 100. It's the fastest way to spot what's hurting a page before you publish it, whether that's a missing meta description, a duplicate H1, or images with no alt text. What the SEO checker looks at: • Title tag, with a live character count against the 30–60 range Google displays • Meta description, checked against the 120–160 character sweet spot • H1 and H2 headings, flagging pages with no H1 or more than one • Canonical URL • Open Graph and Twitter Card tags, with a preview of your og:image • JSON-LD structured data, so you know if your schema markup is actually on the page • Images missing alt text • Word count, internal and external links, robots meta, language and viewport Who it's for: content writers doing a final check before hitting publish, marketers auditing client pages, founders sizing up a competitor's homepage, and anyone learning SEO who wants to see how real pages are built. Everything runs locally on the page you're viewing. The extension collects no data, needs no permissions beyond the tab you click it on, and works on any website. Made by Creative Nexus
