Question 1

How long should my title and description be?

Accepted Answer

Title: 50-60 characters to avoid being truncated in Google. Description: 150-160 characters for the same reason. Going over doesn't hurt SEO, it just means the end gets cut with an ellipsis in search results. Write the important part first.

Question 2

Do meta tags actually affect my rankings?

Accepted Answer

The title tag does — it's a ranking signal. The meta description doesn't directly, but it dramatically affects click-through rate, which indirectly affects how Google views the page. Treat the description like ad copy: it's what convinces someone to click.

Question 3

What does Open Graph do?

Accepted Answer

Controls how your page looks when shared on Facebook, LinkedIn, Discord, iMessage, Slack, and basically everywhere except Twitter. If you've ever pasted a link and gotten a sad gray placeholder instead of a nice preview card, missing or broken OG tags is almost always why.

Question 4

Do I need separate Twitter Card tags if I have Open Graph?

Accepted Answer

Twitter falls back to OG tags if Twitter-specific ones are missing, so technically no. But if you want a different image or description on Twitter specifically (shorter tagline, say), use the twitter:* tags. Otherwise OG alone is fine.

Question 5

What image size should I use for og:image?

Accepted Answer

1200×630 is the safe default — works on Facebook, LinkedIn, Slack, Discord, iMessage. Twitter's `summary_large_image` wants at least 300×157 but up to 4096×4096; 1200×630 covers it. Keep the important content away from the edges since some platforms crop.
