I looked at your most recent video and a couple things stand out to me here. You are on the right track with your SEO, but there are a couple issues that are holding back performance for keywords. Let's take a look at your most recent video:
"MY WAY" Instrumental Nuevo Trap Para Spotify x Instrumental de Trap Para Billboard (Prod. BUFO)
This title is not organized in a way that is going to benefit your SEO. The keywords should be at the beginning of the title and the more viewer-oriented info should be after. Since your keywords are heavily based on 'Instumental Nuevo Trap Para Spotify' that should be the beginning of the title. Personally I feel like you have crammed too much into this title (it is 95 characters, we recommend keeping it under 65). So if this were me I would title the video like this:
Instrumental Nuevo Trap Para Spotify | "MY WAY"
There are some similar issues with the description. You put your links at the top, this is prime real-estate for SEO purposes. You should have the actual description of your video at the beginning. The first 200 characters of the description are the most critical for SEO. But you also need the description to be organic. Currently your description is as follows:
instrumental trap listo para radio,instrumental trap listo para radio 2020,instrumental nuevo trap para spotify,instrumental nuevo trap para spotify 2020,instrumental nuevo trap para spotify 2022,instrumental nuevo trap para spotify 2023,nuevo instrumental trap para spotify,nuevo instrumental trap para spotify 2020,instrumental de trap para billboard,instrumental de trap para billboard 2021,instrumental de trap billboard 2021,instrumentales de trap billboard 2021 "MY WAY" Instrumental Nuevo Trap Para Spotify x Instrumental de Trap Para Billboard (Prod. BUFO)
This is called 'keyword cramming.' All you are doing is cramming in as many keywords as possible and YouTube sees this. It doesn't do anything for you. You need to write an organic and natural description which includes your most relevant keywords. For the purposes of this I am including an English version of what I would do if I were to write a description for this video:
"My Way" 2021 instrumental nuevo trap para Spotify produced by Bufo. This Instrumental de trap para Billboard unique track brings a soothing mix of R&B to your night, thank you for joining and giving us a listen!
This is really simple and rudimentary; I would personally target more keywords specific to the mood of the song, trap beats etc and then fill that in as more of an explanation in the description until I hit 200 characters.
The final issue plaguing your keyword ranks; You only have 7 views. That isn't enough for YouTube to really evaluate how well your videos stacks up against the competition. I know that sounds like a catch-22; how do you get views if you can't rank and how can you rank if you can't get views, but it isn't that bad. YouTube is going to share you out... it is super important that you focus on your data and make smart decisions. You want your CTR and AVD to be as high as possible. It is incredibly important to ensure that every impression counts. So keep experimenting with thumbnails and video (adding visual graphics may help improve watchtime). Improving these metrics improves the amount YouTube shares you out and everything begins to snowball.
