"My provider's panel firewall has me covered." Maybe, maybe not, and it's worth checking. A firewall on the server itself means you control exactly what's reachable, not a guess.

"Those best-of lists are just clickbait, who cares." People asking AI for a recommendation care, because AI reads them. Getting onto one is a real way to get suggested.

After a redesign or launch: list any staging, test, or backup copies of the site, password-protect the ones you still need, and delete the ones you don't. Don't leave them open.

Switching on two-step login? Start with the big three: email, bank, and your main shopping account. Use an authenticator app over texts where you can. Then add the rest.

Set up a separate guest Wi-Fi for visitors. Give them that name and password instead of your main one, and your phones and laptops stay on their own side of the fence.

The habit nearly everyone has: hitting "later" on updates until later never comes. Flip on automatic updates once and the choice stops being yours to forget.

A shop's Facebook was tied to a former employee's email. When that inbox closed, so did any way back into the page. Years of followers, gone. A current recovery email would've saved it.

A QR code is a hidden link you can't read with your eyes. Scammers cover real codes with fake ones. Let your phone show the link first, and only go if it looks right.

The miss almost everyone makes: a beautiful intro and the answer paragraphs later. AI skims, finds nothing useful early, and quotes someone shorter. Lead with the answer.

When you share your location, it usually keeps going until you say stop. So now and then, look at the list and switch off people who don't need to see you.

"My phone only rejoins my real networks." It rejoins any network with a matching name. Anyone can name a hotspot "Home" too. Turn off auto-join for public ones.

"llms.txt sounds like something only coders set up." It's a plain text file you could write in Notepad. A few lines about your business and links to your best pages.

"Nobody knows the link to my bucket, so it's fine." People scan for open buckets all day. A secret link isn't privacy. Set it private and you're not relying on luck.
