Generate the core SEO meta tags for a page’s <head>.
This generates the core meta tags most pages need in their <head> — title, description, canonical URL, keywords, and a robots directive — with live character counts against the lengths search engines commonly display before truncating.
The title tag is what shows as the clickable headline in search results and browser tabs; keeping it under roughly 60 characters avoids truncation, though the exact cutoff varies by pixel width, not a fixed character count, so treat this as a helpful guideline rather than a hard rule. The meta description doesn't directly affect ranking but shapes the snippet shown under your result, which affects click-through — search engines sometimes override it with their own extracted text anyway, so a good description is a strong suggestion, not a guarantee of what's shown.
The keywords meta tag is included for completeness but carries essentially no weight with modern search engines — Google has not used it for ranking for many years. It's harmless to include but won't move the needle; your page's actual content is what matters.
No — major search engines, including Google, stopped using the keywords meta tag for ranking purposes years ago. It’s included here for completeness, but your on-page content matters far more.
Not always — search engines sometimes rewrite the displayed title based on the page content or query, especially if your title tag is very long or doesn’t match the page well.
It tells search engines not to include this page in search results at all — useful for internal pages, duplicate content, or pages still under construction.
