Authority Site Builders, please share how to write efficient articles which withstand the test of time and any Google update earthquake.
I have about 1 hour daily allocated for article writing for my new narrow niche authority site. Please advise how to make the most of it. How is your workflow? Which resources and tools do you use? I envision some semi-automatic AI-supported writing with human editing to pass the originality check, score in on-page SEO and be a pleasant read for humans. No sales copies or conversions here.
