Ah, imagine a swimming pool which is big but filled with many people - that's like a tag with high payout but with a lot of posts too. Try to avoid these "popular" tags because you will be competing with others.

For example, "life" has a total payout of SBD8,566,992.68, and the number of posts are 133784, which is a lot.

Instead, look for tags with lower payout but also lower post number. Less competition, and if you work out the numbers, it's more profitable.

So, for example, if you pick "psychology", you have SBD462,232.37 payout, but only 2475 posts.

Hope this is clearer. :)
