Social Settings For the Post In Yoast
Yoast lets the user set a specific image for Facebook and Twitter with title and description.
So anytime you or anybody else share your post to Facebook or Twitter, it will pick that specific selected image and metadata.
This way you can ensure the quality of your post sharing on social platforms.
Just sharing the post link have no benefits
Just sharing your post to social sites has no benefits if it does not contain a perfect image with good meta title and description.
If you do not select any image in the Yoast plugin, you don’t know which image it is going to pick while sharing on social platforms.
And many times your post will be shared to Facebook and Twitter without the image. It will look bad and do not provide any advantage.
If you are in SEO you will be definitely know that social signals are one of the SEO ranking factors so you cannot ignore it.
