Tags
Publish post

You will find those tags (keywords) in your text and on the tags of the post

When you write a post in the same category as another post you can use the same tags for both post.

It will link the two posts together, and when someone makes a search in SEO on the search bar and write " best income funds" the SEO brings them to my post where I write that in the post and in the tags area. (Top image what is colored in yellow)

In your post you write your tag in the space and Add it. You need at least 3 to 10 tags.
