I remembered that we started collecting this data a few weeks ago, so ran a
query to see what it looks like. While somewhat expected, i found the
results rather surprising still. The top 3 dominate click through's, as the
literature suggests. There is also a very strong drop-off going to the
second page (position 21). Our users do not use search pagination.
This data is an 0.5% sample of desktop users clicking through on results
shown in the Special:Search page. It does not include clickthroughs from
the autocomplete.
