Website Traffic Trend 10/2023 - 3/2023

RFCafe.com Web Statistics October 2022 - March 2023

Banner Ad Impressions 12/21/2022 through 6/20/2023 - RF Cafe

The above chart shows Banner Ad impression rates for the 6-month period of 12/21/2022 through 6/20/2023. The average is around a quarter million per year (2 x 113.5k).

Things are looking up for RFCafe.com website statistics. The trend lines for Page Views, Visits, and New Visits all have a positive slope. Also, you may have noticed that I have been modifying and re-publishing some of the earlier RF Cafe webpages. That involves updating the narrative, verifying hyperlinks (many go dead over time), and cleaning up older graphics. Much has changed in expectations from visitors - especially from the early days in the late 1990s and early 2000s. Competition for visitors is fierce. As always, thank you for your visitorship and stewardship.

Here is a real-time view of the Banner Ads in all eight positions.

Please contact me, Kirt Blattenberger, with any questions.

RF Cafe Banner Adversiting Details

Click here for more detail on the Banner Advertising Plan.

All Banners will be randomly displayed in any of the eight (8) page border positions (see screen capture at left, and info graphic at right), so every company's Banner will have an equal chance of appearing.

A random number generator determines which company's Banner Ad will go in a particular position*. I wrote the code myself and it is very simple and foolproof.

You provide one pair or two pairs of industry-standard Banner graphics are needed for page border impressions - one (or two) 120x450-px graphic for the vertical format and one (or two) 728x90-px graphic for the horizontal format, and also one 330x400-px graphic for the Highlighted Ad impressions on Vendor pages.

  • Term: 3 months
  • Price: A flat price of $300 per month is charged, with a standard 3-month term ($900/term).
    • Additional Banner Pairs* (up to a maximum of 3) may be purchased at discount rates to increase the odds that your company's Banner Ad will be displayed:
      • 1 Banner Pair  = $300/month
      • 2 Banner Pairs = $300 + $150 = $450/month
                                  (= $225/month/Banner Pair)
      • 3 Banner Pairs = $300 + 2*($150) = $600/month
                                  (= $200/month/Banner Pair)
      • 4 Banner Pairs =  $300 + 3*($150) = $750/month
                                  (= $187.5/month/Banner Pair)
    • * Each Banner Pair option adds another set of Banner Ads (120x450-px and 728x90-px) into the random display engine, thereby doubling your likelihood of being displayed. Unique Banner Ad designs and hyperlink URLs can be provided with each additional Banner Pair.
  • Banner Ad Specifications:

    728x90 - Width = 728 px, Height = 90 px

Important Notes:

  • Pixel dimensions and maximum file sizes listed are firm. If you have trouble meeting the file size, I will be glad to help - there has never been an ad I couldn't fit into 45 kBytes.
  • I do not collect page traffic or link click statistics for advertisements. Your website server statistical analysis is a much better reporter of inbound links from RF Cafe than I or anyone else can provide.
  • To the best of my knowledge the page layouts shown are representative of all pages on RF Cafe.
  • I make page layout changes from time to enhance performance.
  • The rel="sponsored" tag is inserted into all coded hyperlinks for SEO compliance.
