Meta tags are HTML elements that provide metadata about a web page to search engines and social platforms. They help improve SEO rankings, control how your pages appear in search results, and determine how content looks when shared on social media. Proper meta tags can significantly boost click-through rates (CTR) and drive more organic traffic.

Google typically displays the first 50–60 characters of a title tag (about 600 pixels wide). For best results, keep your title between 50–60 characters. If it's too long, Google will truncate it with an ellipsis (...). Include your primary keyword near the beginning for maximum SEO impact.

Open Graph (OG) tags are used by Facebook, LinkedIn, Pinterest, and most other social platforms to generate rich link previews. Twitter Card tags are specific to X (Twitter). If Twitter Card tags are missing, Twitter will fall back to OG tags. It's recommended to include both for complete coverage across all platforms.

The canonical URL tag tells search engines which version of a page is the "master" or preferred version. This prevents duplicate content issues when the same content is accessible from multiple URLs. Always set the canonical URL to the primary, SEO-friendly version of your page.

summary_large_image displays a full-width featured image (2:1 ratio, 1200×600 px recommended) — best for visual content, articles, and landing pages. summary shows a smaller square thumbnail (1:1 ratio) — better for concise updates or when the image is secondary. Most websites benefit from summary_large_image for greater visual impact.

Review and update meta tags whenever your page content changes significantly. For static pages, audit tags every 3–6 months. For blog posts, set tags when publishing and revisit if performance is poor. Monitor click-through rates in Google Search Console to identify pages that need tag improvements.

No — Google has not used the meta keywords tag for ranking since 2009. Bing also ignores it for ranking purposes. While it doesn't hurt to include them, they provide no SEO benefit. Focus your efforts on title tags, meta descriptions, and high-quality content instead.
