Optimize Fat Burn

I have several website pages to write, and I am finding SEO content harder than I expected. During my search, I came across pay someone to do SEO copywriting. I have never used this type of service, so I wanted to ask if anyone here has. Was the writing clear and useful? Did the writer understand what you wanted? I would really appreciate honest opinions from people with real experience. Did it make your work easier, or would you rather write everything yourself?
