    New Banner Rates for the Science Online Network (effective September 2001)

    Notes:

  • Minimum Purchase - There is a minimum purchase of 100,000 banner ad impressions (regardless of the time increment of their serving).
  • Serving Increments - Ad impressions can be purchased in one-week increments (e.g.- 100,000 impressions over a one-week period or 100,000 impressions over a four-week period, etc.).
  • Serving Options - For no extra charge, ad impressions can be served on a Consistent (smoothed) basis, Turn-on/Turn-off (flighted) basis, or Interval (pulsed) basis over the course of the banner ad campaign (per note #2 , in one-week increments).
  • Targeting Options - These include Geographic Location of the user, Hours of the Day, Days of the Week and, available in 2002, Discipline targeting (targeting banner ads based on the "discipline tag" of pages served). Please see target premiums above.
  • Site Specific Targeting - Targeting also relates to purchasing ad impressions within specific sites in the Science Online Network (e.g.- STKE, Functional Genomics, etc. pending availability). Targeting a specific site(s) incurs a 50% premium (equal to the 4th target premium).

    Online Flexibility for Maximum Advertising Results
    Online banner advertising offers the ultimate in advertising flexibility. You can decide how, when and how aggressively to advertise by setting the impression level of your ad. Sample options are shown below. Ask your Science sales representative for more details.

    Consistent, or Smoothed, Banner Advertising
    Make sure your message receives a consistent viewership each week by setting a balanced level of ad impressions over your chosen period of time (weeks, months, quarters, etc.)

    Turn On / Turn Off, or Flighted, Banner Advertising
    Set regular time intervals to turn on and turn off banner impressions. You can turn on banner ad impressions when a print ad campaign runs to maximize advertising exposure. Or, run banner ads when your company's print ad is not running to ensure more consistent advertising exposure and sales lead collection. Or as with interval online banner advertising, increase banner ad impressions when new products are to launch, or coordinate increased online exposure with a new advertising campaign, sales promotion, or trade show - the choice is yours.

    Interval, or Pulsed, Banner Advertising
    Choose the intervals when your online banner advertising will increase and decrease. This allows your company the ultimate in advertising flexibility. You can increase banner ad impressions when new products are to launch, or coordinate increased online exposure with a new advertising campaign, sales promotion, or trade show -- again, the choice is yours.
