Frequently Asked Questions
Why does social preview show the wrong image?
Social platforms cache OG tags. After updating, clear the cache: Facebook Sharing Debugger, LinkedIn Post Inspector, Twitter Card Validator.
What size should an OG image be?
1200×630 pixels — displays well on Facebook and LinkedIn. Minimum 600×315. Always use approximately 1.91:1 ratio.
What if I have no OG tags?
Social platforms guess — usually picking a tiny logo and using the page title. Results are unpredictable and look unprofessional.
Do OG tags affect SEO?
Indirectly — they improve social sharing and click-through rates, driving more traffic.
What is the twitter:card tag?
Controls Twitter/X display — summary (small square image) or summary_large_image (large rectangular image). Use summary_large_image for best visual impact.
