For an audio based campaign I'd prefer a catchier and more memorable name than 'ahrefs'? Type that in slightly wrong and you get to a dead end pretty fast.
I'll give you the benefit of the doubt and assume you're trying to be helpful but I don't get why this makes it a good name?
What was that ad I heard the other day, hrefs.com or href.com? Ooops!
I'd always (and always do) google an advert rather than trying to remember the exact website anyway. If you search 'href sep' or 'hrefs seo' or even 'aref seo' it always still comes up as the first result for me.
That is because the whole article is just marketing fluff. Ahrefs is a marketing company with its own spiders etc.. they are not into podcasting at all.
Yes, their name sucks for podcast/radio. But it's too late for them to change that.
