Frequently Asked Questions
What meta tags are required for SEO?
No meta tag is technically required by browsers, but for optimal SEO you need: `<title>`, `<meta name='description'>`, `<link rel='canonical'>`, `<meta name='robots'>`, and the full Open Graph set. Missing any of these leaves SEO value on the table.
How long should a page title be?
50–60 characters. Google truncates titles longer than about 600 pixels in search results, which is roughly 60 characters. Shorter is fine — an 8-word title is better than a 15-word one with filler phrases.
What is a canonical tag?
The canonical tag (`<link rel='canonical' href='...'>`) signals to Google which URL is the authoritative version of a page when the same content is accessible at multiple URLs. It prevents duplicate content penalties from URL parameters, trailing slashes, and HTTP/HTTPS variants.
How do I add Google Search Console verification?
In Search Console, choose the HTML tag verification method. You'll receive a `<meta name='google-site-verification' content='...'>` tag to paste into your `<head>`. Once Google crawls the page and finds the tag, ownership is verified.
What is the viewport meta tag?
The viewport meta tag tells browsers how to scale the page on mobile devices. The standard value is `<meta name='viewport' content='width=device-width, initial-scale=1.0'>`. Without it, mobile browsers render the page at desktop width and scale it down — making text unreadably small.
