It is irksome that those tools we imagine to be most aligned to the
Open Access paradigm do not work in the way that we wish! I wonder
how different sites get different patterns of traffic because of the
way that they are harvested by the various search engines. I have no
insider knowledge as to how Google Scholar works, but I am interested
to see if we can get some global triangulation on this issue.

By way of illustration, I list below a summary of the two months of
search engine referals to, representing just
over 30K downloads. It shows that 3/4 of all search engine referals
come from plain old Google vs 1/7 from Google Scholar and 1/10 from
the rest. Perhaps that breakdown is of all repositories, or perhaps
the figures vary from repository to repository depending on Google-
Scholar-specific criteria.

If you run a repository, please you email me (
with a breakdown of the search engine referals to your site and I
will summarise the result for the list.

76.05% Google
15.25% Google Scholar
