Akashdey9090 Hi, you're not guaranteed to always receive the same number of plays on Humix or generate revenue. Other videos may now be getting shared onto the sites where your videos were getting added previously, or the sites where your videos were being added may've seen a traffic drop, which would cause the number of video plays to fall.
There was a Google update in March which caused a lot of sites to lose traffic, so it does seem likely your videos were getting added to sites hit by the Google update.
My suggestion would be to continue uploading video content to Humix to try and increase the number of overall plays and revenue, you might want to focus on video content that is more likely to generate higher revenue e.g. videos for a US or English speaking audience.
