Optimal Meta Lengths
- Page Title: 50 to 60 characters (~600px). Beyond 60 characters, Google will truncate with an ellipsis (...).
- Meta Description: 150 to 160 characters (~960px). Keep your call-to-action within the first 140 chars.
Open Graph Rules
Use high-resolution 1200x630 pixel images for og:image with an aspect ratio of 1.91:1. Always supply explicit og:title and og:description so links render professionally when shared.
Canonicalization
Canonical tags prevent duplicate content penalties across protocol (http vs https), www vs non-www, and URL query tracking parameters (like UTM tags).
