The Facebook platform relies on its own search algorithms, which differ slightly from Google’s algorithms for searching sites.
But the main idea of these algorithms is one, the artificial intelligence tries to show you the closest things related to your search on the platform. And that is through a set of keywords that he searches for in images, written texts and videos.

Facebook recently started allowing users to edit the description texts of their photos on the platform.
These texts help users with vision problems learn and understand the content of images through applications that read these texts.
This makes your images a little easier to be accessed and understood by these users, as well as easy to access via the platform’s search engine.
