one way to protect you digital foot print is to get a VPN, ( Virtual Private Network, like Nordvpn which keeps your stuff secret) why i believe in this is that it keeps your personal stuff safe like the websites you visit your shopping password and email, ( just your account info to anything you don"t want taken or deleted) your credit/debit info.
internet providers servers
another way is to watch what you post, reread it check over the pictures, watch what you say, etc. why i feel this is in the in the top 3 is that way you don't screw yourself out of a job, but also you can make a good impression
watch what you browse. by browsing, hackers or your internet provider can see what you are browsing, and going in incognito mode wont help, it says that any downloads and search history wont be saved to your browser history, but that doesn't mean it wont show up, it will show up to where your internet provider can see it.
