What am I doing wrong? (Referring Domains)

Hi, I am having trouble figuring out what I'm missing from getting my site ranked higher and I believe it has something to do with the backlinks.
I have paid for some backlinks before which were mainly blogspot blogs, and then another package from Sakar which had a large range of backlinks from different domains.

However after checking Seobility's free SEO checker it is still only showing as 2 referring domains. Some of my competitors have 200+ referring domains but they don't seem much more varied than mine.

What am I doing wrong and how can I get better backlinks? And do you think this is the main issue from getting me ranked higher?

My site is verdiere.art

FWIW, Ahrefs says you have 82 RDs, Semrush reckons 950 RDs. From what I can see they're mainly blogspot (as you mentioned) and the other domains look to be from a Money Robot submission.

Looking at your site I'd take a look at what your competitors are doing re their title tags and textual content. The content on your pages is very similar (maybe one unique paragraph per product, the rest boilerplate), which can be an issue for ecommerce sites.
