Good idea. Google is best for this coz they are the most common search engine used by ordinary people who doesn't have an idea about these websites and to avoid it appearing in the search query as well. Well, as long as many people report it.
In any case people shouldn't be using a website to create their bitcoin wallets in first place! That's just silly and extremely insecure regardless of what website you are using or who controls it.
So when and how bitcoin wallets in mobiles and desktop is considered to be insecured too? The difference is only the latter needs installation.
