Oh sorry man. I understood it other way.
Mostly no mate. Sometimes, I do consider. But performance wise they are not so good.
Instead, I will follow the pattern by my competitors and recommendations of Google Trends as well. Logic is, our competitors (who are big players in our niche) might have already done some analysis and made videos around it. So every time you need not break your head on what to prepare. This is one technique I adopted.
And second one is, I follow GTrends even before starting my script. This is a very good tool of Google which is ignored by many. I think you know abt it. If not, explore it carefully and understand on which
topics you need to concentrate. If you incorporate main keyword, it will give you TOPIC suggestions and its volume. You can filter period and locations as well. Try it once, you will never regret.
And be careful with your Title, Tags & description. Spend good amount of time on these things. These are very important for ranking (as you know). Usually people neglect it, but I recommend you to craft them carefully (craft means literally crafting). For me it takes at least 1-2 hours to finalize this meta data for one video. I think you got it.
Currently, my channel performance is stable. It's new though. Want to try different strategies now, let' see how it goes. But what I understood is, we should be unique in our way of presenting the things. Then we can sustain even in highly competitive niches also.
We all know GOOD THINGS TAKE TIME
All the best mate.
