There's a whole website seemingly built around this concept - WikiHow : )
It bursts at seams with brilliant "do not say!" type of tutorials - one my favorites is "How to Survive a Coup". Here's some of the advice given by the expert authors (who clearly must have survived a few coups back in the day):
"The most important thing to do during a coup is to stay out of range of gunfire [...] Stay tuned into social media sites like Facebook and Twitter to get regular updates on what is happening [...] If you have television, then you can also try watching your local news channel for updates [...] Leave the country or go to a safer region if the conflict continues"
So remember, try staying out of range of gunfire and don't forget to subscribe, everyone
Or blog posts that explain every little thing related to a topic before the information you searched for. In your case, for the article "Shops that are open on Sunday in 2022", <h2> titles would be:
"What is Sunday?"
"What is shopping?"
"Why you should prefer to shop on Sundays?"
"Is the distance to the shop important?"
"Remember to carry money"
etc...
