Album Cover Challenge

I have a website that needs more content, and I am trying to learn how SEO writing works. While searching for help, I came across an SEO content writing agency. I have never worked with an agency before, so I wanted to ask if anyone here has. Did they understand your website and topic? Was the content easy to read? I would really appreciate honest feedback from people who have tried one. What should I know before making a decision?

I have a report project that needs to follow some specific instructions, and I am finding it difficult to put everything together. While looking online, I found custom report writing. I have never used this type of help before, so I wanted to ask if anyone here has. Did the writer follow your instructions closely? Was the final report clear? I would really like honest feedback from people with real experience. What should I check before deciding?
