Keep your profiles up to date
Are you using more than one social media channel? Are you using one less than most of the others? Well if you are, make sure you keep them all up to date including the profiles or directories you don't use; keep all the links up to date.
You've probably seen social media profiles from businesses that aren't up to date, broken links or info that isn't correct, don't let that be your business. Whether its opening times, website links or just general info on the business or store.
Make sure you check directories too, when signing up to yell.com or other business directories keep a check on these too. You wouldn't want a new customer finding you online to see out of date info.
