Meta Tag Generator

At minimum: title (under 60 chars), meta description (under 160 chars), viewport, and robots directive.

Google truncates by pixel width rather than character count, but as a practical guide keep titles under about 60 characters and descriptions between 120 and 160. Wide capital letters eat the budget faster than narrow lowercase ones, so check the preview rather than trusting the count alone.

No. Google has ignored it since 2009 and has said so publicly. It is not harmful, but it is dead weight and it advertises your target keywords to competitors. Leave it out.

Not directly — it is not a ranking factor. It does affect click-through rate, which is why it is worth writing well. Google also rewrites descriptions for the majority of queries when it judges a passage from the page to be a better answer, so treat yours as a strong suggestion rather than a guarantee.

`noindex` keeps the page out of search results; `nofollow` tells crawlers not to pass ranking signals through the links on it. They are independent, so `noindex, follow` is valid and means "do not list this page but do follow its links". Note that a `noindex` page must remain crawlable for the directive to be seen — blocking it in robots.txt means Google never reads the tag.

A canonical tag names the preferred URL when the same content is reachable at several addresses, consolidating ranking signals onto one. It must be an absolute URL, and every page should normally declare itself canonical unless it is a genuine duplicate.

Yes, for any responsive site. Without `width=device-width, initial-scale=1` mobile browsers render the page at a virtual desktop width and scale it down, which fails Google's mobile usability checks and makes text unreadably small.
