We can easily do it with category.
But because tag is randomly created by users, so it's not a default option.
But I really want to change tag pages, so it could be like topic page in Quora.
A tag page has the url like this https://domain.com/tag/abcdefg
I would like to add more information, even in a hard way, like this
if $keyword == "kim-karshidian"
echo "Kim Karshian is a ****** who .....";
echo "<img src=./kim.jpg />";
