Website SEO

I want a good SEO for my wordpress site https://www.teokanistras.gr/

My site is Greek and one category with english articles.

I use All in one SEO plugin. All my articles is copy paste from other sites. My daily organic traffic is very low 20 - 30 views per day.

Any solution for more organic traffic?

My budget is 9 euro for that work.

Thanks!
