The screenshot above looks pretty harmless, doesn’t it? It’s just a list of tags, and it’s just plain text at the bottom of a support page. Now, not quite anyone’s support site, though, it’s JustUno’s, who happens to be competing with… Hello Bar. Devious, I kind of like it and I’m sure lots of smirks were involved at UnoBar.
It will bring UnoBar some search engine traffic looking for Hello Bar, probably more than people who will wonder what that “hello bar” is and will then look up their competitor. Generally speaking, I think it shows healthy self-confidence the acknowledge you have competitors. In this specific case this is kind of a cheeky move, more like a friendly /taunt to the competition than a game-changing marketing tactic.
