Everyone in the crypto space needs to get into the habit of bookmarking the url of their exchanges and online wallets.
Don't google for the exchange you'll be presented with phishing sites in the search results. And don't click on links in emails. Just use your bookmarks and you will be safe.
This is the best approach and it's what I do and advise too. It is safest bookmarking or saving the sites on one's homescreen. Besides, I would advise that people go through the CMC (
coinmarketcap.com) if they aren't sure of an exchange or a coin to get its official web address. It helps that way and saves one the scam attempts and malwares.
