FeedBurner/Feedsky measures the number of hits in a feed by changing the link address, which means it changes the link to an article

This format allows readers to jump to the real address when they open it. Once the jump is out of the question, there is trouble. And links are modified, look uncomfortable, may lose backlinks, and readers are easily confused when collecting.
