People use Google because Google has made search one of the best places in the world to search for something and because the search system is relatively easy for people to accept Google's results.
The problem with Google is their ads. They happily accept money from scammers to put scam sites, phishing links, malware, etc. right at the top of search results. They do zero diligence regarding these ads and don't care at all if their users are scammed because of them. As long as the scammers pay Google their advertising fee, Google will promote anything. Every time one of these scam sites is taken down, a new one pops up at the top of Google search results within a few hours. The best option is to use a different search engine altogether which doesn't do this, such as DuckDuckGo, and also to install the best ad blocker which currently exists, which is uBlock Origin.
I should probably add the line "Verify your downloads" in to my original quote. Yes, that is the correct link, but simply downloading from the correct link is not sufficient to guarantee your safety. Web pages can be compromised, hosting services can be compromised, GitHub accounts can be compromised. The only way to ensure your version of Electrum is legit is to verify the signature using ThomasV's public key.
