Question 1

What length should a title tag and meta description be?

Accepted Answer

Aim for a title under about 60 characters (Google truncates by pixel width around 580px) and a meta description of roughly 150 to 160 characters. MetaGen shows live character and pixel meters with green, amber, and red guidance.

Question 2

Do I need an API key?

Accepted Answer

No. Without a key, MetaGen uses a built-in rules-based generator so it is instantly useful. Add a free OpenRouter key to get AI-written, higher-quality candidates.

Question 3

Can it read my live URL?

Accepted Answer

Yes. On the deployed site, a small server endpoint fetches your public URL and extracts its title, description, and text, since browsers alone cannot due to CORS. A Demo Mode with sample content and a describe-your-page path that needs no fetch are also available.

Question 4

Can it create the og:image too?

Accepted Answer

Yes. The built-in OG image generator renders a real 1200 by 630 pixel share image from your title, description, and domain with three templates, downloadable as a PNG, entirely in your browser.

Question 5

What does the copy-paste block include?

Accepted Answer

The full head block: title, meta description, canonical, the complete Open Graph set and Twitter card tags, HTML-escaped and ready to ship.
