Question 1

How long should Title and Description be?

Accepted Answer

Keep the title under 60 characters and the description under 160 characters — anything longer gets truncated in search results.

Question 2

What are Open Graph tags?

Accepted Answer

Open Graph is a protocol originally introduced by Facebook. Tags like og:title, og:description, and og:image control how link cards look when shared on social networks, and are now widely supported.

Question 3

What happens if OG tags are missing?

Accepted Answer

Without OG tags, social platforms guess the title and image themselves, making the shared card unpredictable. Set at least og:title, og:description, and og:image.

Question 4

How is the favicon checked?

Accepted Answer

Following browser convention, we probe /favicon.ico at the site root and let the browser actually load it to verify it exists.
