• `<title>`: the most important on-page signal and the headline in search results. Make it unique per page and descriptive, roughly under 60 characters.
• Meta description: often used as the snippet under the result. It does not directly improve ranking, but a good one improves clicks. Aim for about 150–160 characters.
• Canonical link: tells search engines which URL is the main one when the same content is reachable through several URLs (tracking parameters, sorting, http/https), so ranking signals are not split.
• Robots meta: noindex keeps a page out of search results (useful for search-result pages, drafts, account pages); nofollow asks crawlers not to follow its links.
• **Open Graph (og:*) and Twitter card tags:** control the title, description and image shown when a link is shared in WhatsApp, LinkedIn, X, etc.

The keywords meta tag is ignored by major search engines.
