I have the best and original articles in my field, but my website doesn't even appear on Google.

Dear respected experts, I have a problem with my website since the end of 2020 and into 2021. It is in a declining state, and I don't know the reason behind it. I believe I offer the highest quality service in my field, with original content and social media support. However, someone is copying some topics from my site to their own, and my site is being blocked ahead of mine in searches. I can't understand why this is happening. Do you have any advice or suggestions regarding this issue? My earnings are not the same as before. I understand that people are removing ads or not clicking on them, but previously I used to have daily hits of over 1,000. Currently, if I see 700-800, I am happy with social media support. Can you help me understand the reasons behind this and what needs to be done? Also, I am disappointed that poorly written articles are ranking higher than the ones I put effort into on another website. My website address is www.dhbtdersleri.com. Your feedback and suggestions are important to me, and I thank you in advance.
