Search yourself online. Do you know what is online about you? It is recommended that you search your name online regularly. You might be aware of the content you post about yourself online but are you aware of what others post about you? Set up Google Alerts - where you will receive an email every time your name appears in a Google Search results, remember: If your Instagram or Twitter pages appear you can change this by adjusting your privacy settings. 

Check your privacy settings. Make sure you know what information you are sharing on the platforms you use in particular social networking sites. Most social networking sites have privacy settings to help you manage the content you share and who you share it with; you can decide if you want your posts to be shared with all your online followers or a specific list of followers or the public. Keep in mind that your friends’ content and their settings can also affect your digital footprint; remember you're only as private as your most public friend. 

Think before you post. Be careful of anything you post online. Before you post that silly photo of a friend on Instagram ask yourself if you would be happy for that same friend to post a photo like that of you. Even if a service states that once you post a photo it will disappear after a certain period of time, once something is online it could potentially be there forever.

Deactivate and delete. If you stop using a social media account, it's a good idea to deactivate or delete your account. Deactivating your account means that you can still access the content posted for a period of time. Deleting the account removes the account completely. Over time this will prevent it appearing in search results on a site or through a search engine and it will remove the risk of these accounts being hacked without you knowing.
