RF Cafe typically receives 10,000-15,000 website visitors each
weekday and about half that on weekends (see chart) - currently averaging nearly 4 million
pageviews per year! RF Cafe is a favorite of engineers, technicians,
hobbyists, and students all over the world. With more than 17,000 unique pages in
the Google search index, RF Cafe returns in favorable positions on many types
of key searches, both for text and images. New content is added on a daily basis.
Here is some
SEMRush comparison data.
9/17/2023 Update: The 160x600-px banners have been changed to 120x450-px, and
now there are three in each border rather than two. This increases the likelihood
of your Banner being seen.
 RF Cafe Banner Advertising scheme
(8/6/2022)
NOTE: I reserve the option to refuse ads which I do not feel are appropriate
for the RF Cafe mission.
RF Cafe on a Samsung S4 smartphone. At the time of this writing,
RF Cafe scores an "Awesome! This page is mobile-friendly" on Google's Mobile-Friendly
Test.
Website Traffic Trend 10/2023 - 3/2023
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). Not included are the Highlighted Ads that appear on Vendor
pages.
Things are looking up for RFCafe.com website statistics. The trend lines for
Page Views, Visits, and New Visits all have a positive slope. I have put a lot of
effort into making pages compliant with Google's "Mobile Friendly" requirements,
so that probably has something to do with it. 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.

All Banners will be randomly displayed in any of the six (8) page border positions
(see screen capture), 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 a pair of industry-standard Banner graphics are needed for page border
impressions - one 120x450-px graphic for the vertical format and one 728x90-px graphic
for the horizontal format, and also, a 330x400-px graphic for the Highlighted Ad
impressions on Vendor pages.
See Newest Option.
- Contract Length = 3 months
- Price: A flat price of $400 per month is charged, with a standard
3-month term ($1,200/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 = $400/month
- 2 Banner Pairs = $400 + $200 = $600/month
(= $225/month/Banner Pair)
- 3 Banner Pairs = $400 + 2*($200) = $800/month
(= $200/month/Banner Pair)
- 4 Banner Pairs = $400 + 3*($200) = $1,000/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.
- If your company is a parent to other related companies, the above additional
Banner Pairs can be applied for each company, up to a total of three (3).

Banners for only $400/month (see discount rates above). However, only one hyperlink URL can be accommodates
for each of the two Banners.

but only one hyperlink URL.
- b. The 120x450-px Banner can display information about one or more websites,
but only one hyperlink URL.
- c. The websites can be distributed any way you want between the two Banners,
keeping in mind that my system can only use one hyperlink URL per Banner.

to its website, and Company B could be on the 120x450-px Banner with a hyperlink
to its website. Or, you could have Company A on one of the Banners along with
Company C or Company D, and Company B on the other Banner along with
Company E or Company F.

automatically be rendered in the 120x450-px format. File size of 45 kB still
