Yahoo / Overture Click Fraud?


Yahoo / Overture advertisers may be getting RIPPED OFF!!!


Merchants charging the Pocket Merchant and Pocket Spectrum have reported charging problems when using some 110 volt inverters in vehicles.

It seems that many 110 volt vehicle inverters put out enough "hash" to confuse the "brain" or CPU inside the printers charging system. 

 

Many of these vehicle systems are "Square wave" inverters, which put out 110 volts, at 60 cycles per second (known as "Hertz" instead of Cycles since the 1970's) in a pure "on/off" or square wave instead of the sinusoidal or "sine" wave put out by the power companies..  A square and sine wave are shown below:


Since a square wave is composed of an infinite number of higher frequency harmonics of the base frequency, there is a lot of high frequency noise in a square wave, overwhelming the little Pocket Merchant charger's CPU.

If you are having this problem, you can either charge your Pocket Merchant at home in the evenings, or you can get a Pocket Merchant Vehicle Charger.  If not, it is still a good thing to know if any other devices misbehave when used with a vehicle's 110 volt inverter.  Also, there are companies that make "Sine Wave" inverters if you have the need. Another note: remember these inverters are relatively low power, and they cannot operate items like heaters, blow dryers, etc.



If you advertise with Yahoo / Overture READ THIS: 
A recent article by Anti-spyware activist Ben Edelman has flagged a spyware-powered click-fraud scam using Yahoo's Overture advertising service to RIP OFF ADVERTISERS!  The eWeek report can be viewed here.  Ben's original article can be viewed here.

Basically, spyware sites using special software are causing user's machines to automatically click on paid advertisements!  This is expensive to anyone who pays for the clicks, and Yahoo splits the advertising revenue with the spyware company!

Ben's article shows:   "On a test PC with 180solutions, I browsed Nashbar.com, a popular bicycling retailer. I received a pop-up that immediately forwarded traffic to a Yahoo Overture PPC link—faking a click on that link, and charging an advertiser as if a user had clicked on that link, even though I had not actually done so," Edelman said.

Those of you who advertise on Overture know it is not cheap.  Typical clicks, depending on keywords cost the advertiser anywhere from a dime to SEVERAL DOLLARS EACH!   

We feel we have seen this in action  here.  Yahoo's click-through ratio recently skyrocketed from an average 1.40% to 3.39%.  Any SEO expert would tell you that you made a major positive change to your site, but we made none, and sales and applications have actually reduced lately, rather than increasing!  We are actually watching as our advertising dollars go.. poof! It looks like Google is going to get Yahoo's budget until they cease doing business with spyware and false PPC companies.

 


Remembering that PDA phones are phones, we have to realize that the wireless radios inside (either CDMA or GSM/GPRS) are optimized for the best reception when being used as a phone.

When we use them as a PDA, there is a tendency to operate them with the unit laying on it's back on a desktop or other surface.  Due in part, to a property of the carrier's signal called polarization, the unit will get it's best reception when the antenna is pointed up and down:


When the unit is laying on it's back, the antenna is 90 degrees out of phase with the transmitted signal, and the connection is at it's worst for that particular location!  Height helps as well, holding the unit at head level can give you a much better signal than at waist level.  This helps by reducing the interference, absorption and clutter caused by furniture, file cabinets, and people.

Pocket Verifier Professional only sends or receives data when the "Activate", "Charge" or "Void/Credit" buttons are pressed, so you can use the unit on it's back (or any position), simply pointing it vertically when you actually activate or charge a credit card!  Easy!  In problem areas, some merchants actually hold the unit vertically, and as high as they can.  This is known as the "Statue of Liberty Authorization" and has saved merchants dozens of sales over the years.
