Meta tag analyzer
Paste your page's HTML source to audit all SEO meta tags — title, description, Open Graph, Twitter Card, canonical, and robots.
What meta tags matter for SEO
Meta tags live in the <head> of your HTML and communicate page information to search engines and social platforms without being visible on the page itself. The most critical are: title tag (50–60 characters optimal — appears as the blue link in search results), meta description (150–160 characters — the preview text under the title, not a ranking factor but heavily influences click-through rate), canonical URL (prevents duplicate content issues by pointing to the authoritative version of a page), and robots meta (controls whether search engines index and follow links on the page).
Open Graph tags control how your page appears when shared on social media. Twitter Card tags do the same for Twitter/X. Without these, social platforms scrape unpredictable content for link previews. Use this analyzer to audit any page's meta tags by pasting its HTML source — obtainable via View Source (Ctrl+U) in any browser.
