Indeed, sometimes it can be tricky to access a link from an unknown website.
But this situation is know on google first page too. A lot of scammers buy a domain,make some subdomains like: trzor.shop.domain.com and add it as advertisment on google first position.
You can be scammed in a lot of ways.

I guarantee you that on https://promo-wallet.com will never be ads or something shady. Only direct redirects to Ledger shop or Trezor shop

Be safe !
