Frequently Asked Questions

What's the ideal title and description length?

Aim for 50–60 characters for titles and 150–160 for descriptions — beyond that, Google truncates them in the SERP.

Do I need both Open Graph and Twitter tags?

Open Graph covers Facebook, LinkedIn, WhatsApp and most chat apps. Twitter falls back to OG, but adding twitter:card explicitly gives you the wide image layout.
