Introduction
In this test we investigate which speed tests do or do not show advertisements. This is because showing unsolicited advertisements can be considered an invasion of the user's privacy.
Method of measurement
For this test, we perform a speed test and indicate whether or not advertisements are present.
Speed tests to test
Because this is a relatively simple test -in contrast to the clutter free speed tests test- the unique speed tests as collected at ZOMDir will be tested.
Note that speed tests, which provide the user with different options for using cookies, are tested twice. Once with all cookies rejected and once with all cookies accepted.
