“Human sounding” isn't the same as high quality. I'd focus on the process around the writing: SEO research, useful coverage, relevant internal links, and a content calendar where each article answers a different reader question.
For an equipment buying guide, for example, research should help you work out what buyers actually need: running costs, common faults, inspection checks, spare parts availability. Then give the AI reliable material to build from. “Make this more engaging” wont fix missing information.
Internal linking helps when there's a useful next step, like linking that guide to a maintenance checklist. The calendar should organise those related topics without turning the same advice into five slightly different articles.
I'd look for tools that support that whole workflow, then check the draft for unsupported claims and vague advice. Better wording is useful, but better information gives the reader a reason to stay.
