What meta tags are most important for SEO?
The most important tags are: <title> (the page title shown in search results), <meta name='description'> (the snippet below the title), and <link rel='canonical'> (to prevent duplicate content issues). Viewport meta is essential for mobile rendering.
What is the optimal page title length?
Google typically truncates titles at 50–60 characters (about 580px wide). Aim for 50–60 characters to display the full title. Include your primary keyword near the beginning.
What does the robots meta tag do?
The <meta name='robots'> tag tells search engines whether to index the page (index/noindex) and follow links on it (follow/nofollow). Most product pages should be 'index, follow'. Use 'noindex' for thank-you pages, checkout pages, and duplicate content.
What is a canonical URL?
A canonical tag (<link rel='canonical'>) tells Google which version of a URL is the 'original' to prevent duplicate content penalties. Use it when the same product page is accessible via multiple URLs (e.g., with and without tracking parameters).
