Tracking dissemination of open access publications I recently published a paper in an open access journal, allowing me to archive the post-print in other platforms, e.g. in my university's repository, or on ResearchGate.

I wonder however whether I should attach the PDF directly on these secondary platforms, or just share a link to the journal's website, where the paper is anyway freely available.

Won't multiplying the sources of the pdf make it more difficult to reflect the actual number of views or downloads of the paper? Although citations should anyway be counted properly, I assume number of reads/downloads also might influence potential readers in finding relevant papers, and I'm not sure if e.g. ResearchGate synchronizes counting with other platforms.
I think this is only a concern if you believe that people choose what to read based on how "popular" it is in terms of reads on sites such as ResearchGate. I really hope that this is not the case.... so long as it's citations that you are tracking (which is itself a flawed metric, but less so, and is one that is commonly used), then it doesn't matter where the paper is hosted - what matters is keeping it as accessible as possible.
