I have the most high-quality and original content in my field, but my website doesn't even appear on Google.

Dear esteemed masters, I have a problem with my website since the end of 2020 and 2021, it has been in a decline and I do not know the reason. I believe I provide the highest quality service in my field and my articles are original. However, someone is showing some topics from my website on their own site, and as a result, my site is blocked in searches. I cannot understand the reason for this. Do you have any advice or suggestions on this matter? My earnings are not the same as before. I understand if people are removing ads or not clicking, but my website used to have daily hits of over 1,000. Now, if I see 700-800 hits a day, I am content with social media support. Can you help me understand the reasons and what needs to be done? Additionally, it is frustrating to see poorly crafted content outranking my carefully written articles. My website address is www.dhbtdersleri.com. Your insights and suggestions are important to me, thank you in advance.
