メタタグとは？
Meta tags are HTML elements that provide metadata about a web page. They appear in the <head> and are not visible to users, but are read by search engines and social media crawlers.
SEO meta tags
The title tag (50–60 chars) and meta description (150–160 chars) are the most important for SEO. They appear in Google search results as the blue link and grey snippet.
Open Graph protocol
Developed by Facebook, Open Graph tags (og:title, og:description, og:image) control how your page appears when shared on Facebook, LinkedIn, Slack, and WhatsApp.
Twitter Cards
Twitter Cards control the preview shown when your URL is shared on X (Twitter). summary_large_image shows a large image and gets significantly higher engagement.
