I have a serious question. Its true that I've gaining so much from TubeBuddy. But my videos aren't growing. They have a higher SEO score too. Should I try vidIQ?
As Brave Starr said, look into and explore your options, but I personally don't know that much about them. What I will say, is if your SEO score is set to incognito mode, your SEO score might be lower with TubeBuddy because TubeBuddy is giving an accurate, non biased score. Incognito mode will effect your TRUE seo score, and not all seo scores you see on other programs are actually correct.
The other things to point out is you're hiding your subscriber count. Why? Hiding your subscriber count tells your audience you're trying to hide something, meaning there's a trust factor which could be impacting your views. There's also more to channel performance than just SEO scores. A great SEO score isn't going to make your channel any more clicked if the thumbnail and topic aren't that great.
Plus your channel banner is just your name, it doesn't tell potential subscribers what your channel is about or why they should care, mixed in with you hiding your sub count, it gives indications that there's something being hidden on the channel from the audience and I just wonder why?
Personally I don't think your thumbnails are all that optimised. A good SEO score doesn't mean anything if your thumbnails don't look well designed and therefore not clickable. All an SEO score does is show where your video shows on someone's screen, but just because you rank higher than another video doesn't mean you're going to get clicked. If someone else has a better more interesting thumbnail than yours, that other video will get the click instead of yours even if your SEO is optimized.
I'd be looking into your thumbnail design and study high performing thumbnails first before worrying about your SEO score.
And I'd have your channel sub count not hidden either. it will give your audience more trust.
That's about all I can say though, asking about someone else on this forum is a bit like going to Adobe Premiere's forums and asking if you should try Davinci Resolve instead.
