I have newly created a site and made it live recently but my site showed 22% spam score my site is https://www.ecoguardtechnologies.com/

If anybody has a solution please share it with me so I can reduce it.

There are many solutions written but they are not working in my case so please provide me with the best solution. For the last 2months, I am working on backlinks also but no change in the Spam Score.
