Credit Card Web Transaction Performance Index: FAQs

A credit card web transaction performance index is something that many are not so familiar. There are a number of providers of performance indices and for credit card websites and one of these is the Keynote Performance Index for credit card web transaction. The index measures the performance as well as the accessibility to go to a chosen site for credit card and to log in to perform the proper action as well as to check or sign out from these credit card sites. The measurements that are used in these sites were taken from the metropolitans in the United States with the ten largest areas namely: Washington, D.C, San Francisco, Philadelphia, New York, Los Angeles, Houston, Detroit, Dallas, Chicago, and Boston. The measurement is taken through the use of high speed links that are attached to the key areas of the largest Internet Service Providers in the United States.

Among the credit card home page of credit card companies whose performances are being monitored by Keynote are that of American Express, Bank of America, Capital One, Chase, Citibank, Diners Club, Discover Card, HSBC, Providian, US Bank, and Wells Fargo. The credit card sites that are listed in the Index were selected based on data on the frequently visited credit card websites. As to how the measurements in the index are taken, the Keynote index takes the data on an hourly basis from 8 in the morning to 12 midnight at Eastern Time and from Monday to Friday. A subscriber of the Keynote index can receive the measurement on a 24/7 basis. A more advanced subscriber can actually do performance evaluation through the MyKeynote data portal and measure based on agent, backbone or city performance. The technology that is employed to take the measurement of the credit card web transaction is the Keynote Transaction Perspective Service which actually makes use of the Internet Explorer to browse and to measure the speed of the download for business users that has T-1 or T-3 speed connections.

As to the factors that affect the measured performance, the aspects that cause differences in the performance are the backbone connectivity, the geographical location, and the network infrastructure. The performance is monitored by Keynote through its measurement agents that log in into the websites of those credit card companies. The agents will log in particular credit accounts they maintain, which are standard consumer credit accounts that were established by Keynote, in all of these credit card companies. Then the agent looks on the latest charge information in the account and then log out the account. After which, the transaction measurements are calculated. First to be measured is the success rate of the transaction. To measure this, Keynote takes the ratio between the attempted transactions from that of the completed or successful transaction. The transactions that were unsuccessful are those in which there was a failure to download either correctly or completely or both on any of these web pages. Also, an unsuccessful transaction is recorded if an error is detected on any page or if the transaction is not completed at a time specified. The time specified is actually determined by just multiplying the number of pages in the web for every transaction by 12 seconds. This however differs in terms of the design of the site as well as the log in and the log out process provided by the site. The performance is calculated on the average or median measurement of all the measurements taken during the reporting period. If you want to check for updates on the performance report, you need to check every Wednesday as it is the day when the report is posted and the ranking for the sites are published together with the previous week's ranking.
