What is wrong with this site?

I don't speak English, I translated, I hope I explained the problem.
Site: herbaldunyasi.com

Greetings. I have a problem but I can't solve it. I would be very grateful if you could help me with this. I am explaining it in an itemized way so that I do not miss even a small detail.
- When I first got into the Herbalife business, I bought a domain. But it was forbidden to spend the name herbalife in the domain. I brought this site to the first page in 2 months. Then I had to do a 301 redirect because of the name.
- I waited for it to sit after 301, but the site did not sit for 2-3 months. There were even worse developments. First my Google Adwords account was suspended. Then my Google Shopping account was suspended. I used cloaker for 1-2 weeks with someone's advice. Then I didn't feel comfortable and removed it.
- Whatever I have done since that day, I could not bring the site to good places and it comes up to the 2nd page at most.
What is the problem with this? How do I know if my site is a problematic site in the Google database or not? Or is there a way to solve where there is a problem?

So, you are running ads on Google for this site? If so, the issue for not being shown on page 1 is simple. It is within the settings.

Simple answer: Competitive niche.
You won't make it in the health niche without some serious expenses

Herbalife and those pyramid errr "home supplement mlm" offers are very saturated and competitive.

The main corporation also are very vigilante in filing trademark disputes on affiliates that use their brand or name in any way - even variations and spinoffs that are close to their name.

Ranking organically will be very difficult, but not impossible, as some of the sites in this area (including Herbalife itself) have been around of decades at this point and build up huge backlink profiles.

Long tail niche keywords would be your best bet to rank organically, along with ads. Unless you have a creative spin to build authority within that space and backlinks.

The site may be missing important features or have outdated content.

Check if the website redirect was done correctly, follow Google rules for ads, use clear tactics, create helpful content, fix bad links, adapt to changes, learn from competitors, and ensure your site works well on phones.
