No doubt many of the suppliers are on Google, they would be sightly silly not to have their websites indexed on Google after all. That said, Google is full of suppliers, some legit, some scammers and so on. Unfortunately, Google only lists websites, they don't verify that they are safe to trade with and there are plenty you will find that aren't, as many others discover through trail and error.
All suppliers in our directory have undergone a verification process to ensure they are 100% safe to deal with for our members, and if there is ever any conflict at all, SaleHoo can step in and resolve the issue on behalf of the member.
That's just our directory, we also have a very active forum that assists members with advice and ideas, we have educational tools to assist with members ultimate success and so on, we're far more than just a directory, but that said, our directory is SAFE, unlike Google.
