SEO Toolbar: Domain Authority, Traffic & Keywords - Semantic Pen

Description

Analyze Domain Authority, Traffic, Keywords, Web Vitals, Meta Tags & Technical SEO with Semantic Pen's comprehensive toolkit Semantic Pen SEO Toolbar shows the key SEO facts about any website in one click. Open it on a page to see how strong the domain is, how much search traffic it gets, how old it is, and whether the page itself is set up well for search engines. What you can check: Domain metrics: Domain Authority, Page Authority, spam score, and counts of linking pages and nofollow links. Traffic and keywords: estimated monthly search traffic, total search volume, and how many keywords the site ranks for in the top 3, 10, 50 and 100 results. Domain age: when the domain was registered and how old it is. Page speed: Core Web Vitals from real Chrome users (LCP, INP, CLS, TTFB and FCP), each marked good, needs improvement or poor. On-page SEO: title and meta description with length checks, canonical URL, robots tag, language, word count, and quick links to the site's sitemap and robots.txt. Headings: the full H1 to H6 outline of the page. Links: internal and external links with their nofollow, ugc and sponsored attributes, plus an option to highlight nofollow links on the page. Images: every image with its alt text, size, lazy loading and WebP format. Social and structured data: Open Graph and Twitter Card tags with a share preview, plus any JSON-LD schema found on the page. You can download the links, images and schema lists. The extension only reads the page you are viewing when you open it, and domain lookups are cached for a week so repeat checks are fast.
