Hey Buddy! you still have a lot of works to do on the site, I understand that the website is based on Lottery and Betting, you need to optimize the site for those keywords.
And second you mentioned that your DA and PA is good, no, you only have PA 7 and DA 5, that's not good enough, you need to work on your backlinks.
There are few sites I am currently working on for my client, the first one is xnxx which is based on adult niche, and the second one is xvideos mzansi, also on adult niche, these sites are quite new just like yours and I have started working on the on-page and off-page SEO, I want you to check these sites in few weeks maybe you ll get some motivations from them.
