after I lost so much subscribers, I am now experience another problem which is losing my view counts on my videos. What is going on to my channel why does this bugs love me! HELP looking for solutions.!
It might not be a bug it could be YouTube removing views as they don't pass their threshold of what they class as a view (normally under 30 seconds) - this is done to ensure that your statistics such as views / subscribers accurately reflect your channel, and aren't influenced by bot views etc
Would it cost me to an invalid activity? somehow YouTube might think it was a bot, I am doing things like proper tags, using keywords, and good topics on content that is why I got my views.
Typically no this wouldn't be classed as invalid activity as long as it isn't happening all the time or in large quantities. Youtube algorithms can predict or suggest how many views a video should have within an amount of time anything that massively goes over this could lead to them investigating or holding those views from your stats while they check their legitimacy. Nothing really to worry about, as long as you labelling them correctly and not doing anything against their policy terms then you should be ok
