Several months ago, I created my first website from scratch so I could implement SEO actions and learn from my mistakes and successes. I haven't had much time to pay attention to it in the past, but now I do. I have a good knowledge about SEO in general, but not about the technical side of website development (that's why I decided to start this site, to learn), but this problem is eating my head up. While I know the site has a huge gap for improvement in terms of SEO, I think there's a more serious underlying technical problem I can't quite pinpoint.
My site is a personal blog. Over the past few months, I've received between 100 and 200 impressions per day and an average of 2 to 5 daily clicks. I also see my landing pages duplicated and not updated when I search for my site with the site command in the SERPs, I also just realized that I have 2 robots.txt, one for example.com and another for www.example.com (it should be one)
I would like to know if someone with technical experience could help me understand what the possible problem could be.
thank you community!
