Keywords for Facebook Posts and the Best Facebook Post Format
On this pageShowHide
Quick answer
Use the words your customers actually use (product names, problems, places and questions) naturally in the first line of your Facebook posts, in your Page's About section and in image alt text. Both Facebook search and Google read that text. For reach, short vertical videos (Reels), carousels and native photo posts do better than link posts.
Key takeaways
- Put the main keyword in the first line of the post.
- Local businesses should use place names and service words.
- Reels and carousels usually reach more people than plain link posts.
- Use one to three relevant hashtags at most.
How to find keywords for Facebook posts
You don't need a special tool:
- 1Type your topic into the Facebook search bar and note what it suggests.
- 2Read the questions customers ask in comments, messages and reviews.
- 3Reuse the keywords from your SEO keyword research. People use the same words on Google.
- 4Add your location if you're local ("Houston roof repair").
The best keywords are usually sitting in your inbox already, in the way customers describe their problem.
Where to put keywords on Facebook
- The first line of the post. It shows in feeds and search previews.
- Your Page name, category and About section.
- Image alt text (edit the photo, then alternative text).
- Video titles and captions.
- Event names and descriptions.
Write for people first. A first line that makes someone stop scrolling beats one stuffed with keywords.
