When writing an affiliate article, using only one keyword can make the article look too repetitive, so keyword variations are important. Keyword variations mean different ways people search for the same thing, like "best phone under 200" and "cheap phone under 200". These are different searches but the same idea. Adding these variations naturally inside the article helps the page show for more searches. The main focus should still stay on the main topic so the article does not lose direction. How do others handle this in their articles?
