I think you mean a ‘me too’ positioning strategy. There may be a more professionally recognised word for it though, although ‘me too’ appears in text books. This is basically where a company adopts a tried and tested strategy of others, because it works and theres room in the market for more competitors.
Now can you answer my question on synergistic marketing?!
