    Since we've migrated our website and AWSTATS from IIS6 to IIS7, our unique
    visitors are cut in half:

    Does anyone have a logical explanation for this?

     
  • Hello,

    assuming that the data you show come from the "Days of month" section I did an
    analysis of your data. I found no explanation, but I hope my observations help
    you to look into the right direction:

    1) The headline of the first data column says "Number of visits" and not
    "Unique visitors" (AWStats 7.0 build 1.972). These are different concepts!

    2) I plotted the "Number of visits" column against the other data. These
    pictures seem to indicate that AWStats counted about 25 - 30 "empty" visits a
    day that did not cause any traffic, i.e. no increase in the Pages, Hits, and
    Bandwidth figures.

    Regards
