How to make effective post on facebook?
Keep it short.
People like to scan on Facebook. Keep your writing short for better responses.
Use big, beautiful images
Posts with eye-catching photos and videos stand out in News Feed, making it more likely that people will like, comment and share.
You don't need a professional photographer or a posh camera – just try to show products or services in the best way you can.

Share exclusive content and info with Facebook Adverts
Offer special deals to customers to keep them interested and drive sales. If you have loyal customers, let them know about special events or deals that reward them.
To reach more people, you can run adverts that get more people to engage with your posts, or even bring them directly to your website.

Respond to customers – and keep a calendar
People like it when you listen to them. When you reply to posts and comments quickly, you'll notice that customers are more responsive too.
When special events and holidays are on everyone's mind, mention them in your posts. Planning and scheduling posts around important dates – such as Valentine's Day, Black Friday, Cyber Monday and more – means that you'll be more likely to get people talking.

Post for the right audience
Posts are more effective when the people who care see them.
If you have customers who live in different areas or speak different languages, you can create posts just for them. Write a post and choose the locations and languages you want. When you publish your post, it'll show up in just the locations or languages you've picked.

Link them directly to your website
When you add a link to your post, it automatically creates an image from the website and a large clickable area that makes it easy for people to go to your website.
You can also customise the headline and description to give your customers more reasons to click.
Link them directly to your website
Post more of what customers want
When you learn how your customers are responding, you'll be able to post more of what they love. Posting on your Page is about quality, not quantity. From there, you can post more of what they like and avoid posting what they don't..
