Thanks :]
When picking a topic, make sure it is a broad topic so it fits more people. Writing with a variety of sentence types also makes it more interesting; a boring article won't get many readers. Try not to repeat words too. Instead of saying "this is very good and this is also very good, and they work very well together," write something more along the lines of "these two cards alone are good, but are especially great together."
Hope I helped.
