Hey @thandavakrishnatk! I'll take another keyword for example: "Android Wallpapers"
This is a popular keyword, but again, we have another related keyword: "Android Wallpapers HD"
You can keep your URL structure like: example.com/android-wallpapers
In this article, you can include all the related keywords like "HD", "Download", "Samsung", "Pixel", etc...
You can keep your permalink with your primary main keyword and you can keep all the other natural related keywords in your article.
