I’ve been using 1&1 for web hosting since 2003. The cost went up last year, but I’ve stuck with them, partly out of laziness and partly because they’ve been reliable. They recently went through a merger and renamed themselves as 1&1 IONOS. I’m all for this rebranding; searching for “1&1” has always been a crapshoot, whether it’s in Google, my email, or my Evernote database. Whoever decided to name the company using one digit, an ampersand, and no actual letters clearly did not run that past an SEO guy. I think that maybe the guy who named the company “1&1” was stuck in the old “telephone book” mindset, where he wanted a name that would float to the top of most sort orders.
“IONOS” is a name that actually contains enough letters to form a unique search term, so for that alone, it’s way better than 1&1. I’m not entirely on board with the whole name being in capital letters though. That makes it seem like it’s an acronym, and (as far as I can tell) it’s not.
