The Explore Section Algorithm
Here we enter mechanisms that are very useful for Creators to know, in fact this section is dedicated to showing the posts of those we do not follow, an excellent opportunity to reach new potential followers.
The algorithm will look at how other users similar to us have interacted with a content to interesting for us too. For example, if we interact with profiles that talk about marketing, it is very likely that others will appear in the explore section. However, this is influenced above all by the people who code number of philippines already interact with that post.

A practical example: I have a travel profile and at one point I create a post that talks about tourism marketing. If my followers follow me for inspiration and not for education (they are not other marketers, they are looking for travel information) and interact with this post, the latter will not magically be seen by other marketers in the Explore section because the category of those who have already interacted is very different.
It is important to choose the type of content: if our target audience interacts often with videos, Instagram will promote these in the Explore section.
