Why preview images matter
When a link is shared, many platforms display a title, description, and image. A relevant image helps people understand what they are opening, especially for tool pages and guides.
Good image habits
- Use a clear image that reflects the actual page topic.
- Keep important text away from the edges.
- Use stable public URLs.
- Check previews after major metadata changes.
Common mistakes
Do not use the same generic image for every page if it makes links hard to distinguish. Avoid images that imply awards, certifications, or guarantees the page does not provide.
FAQ
Can a platform cache old previews?
Yes. Some platforms refresh slowly or require a preview debugger.
Should OG images include small text?
Use text sparingly because previews can appear small on mobile.
