Many times journal sell the article for few dollars. Such articles are available online in researchgate. So journals revenue may suffer. What do you think
It is possible specifically an emerging journal who may benefit from monitoring the traffic through its website. However, it may not be relevant to established journals whose visibility is well established. Perhaps, a balanced approach is to refer those who request a full text to the website of the journal. On the other hand, some authors may argue that by posting a full text and promoting its direct access through Research Gate, their own RG scores improve; but I am not in favour of this argument.
