Item 2.02     Results of Operations and Financial Condition.

     On July 26, 2005,  Keynote  Systems,  Inc. (the  "Company")  issued a press
release  announcing  its results for the fiscal  quarter  ended June 30, 2005. A
copy of the press release is attached as Exhibit  99.01 to this Current  Report.
This Current Report and the exhibit attached hereto are being furnished pursuant
to Item 2.02 of Form 8-K and shall not be deemed "filed" for purposes of Section
18 of the Securities Exchange Act of 1934, nor shall they be deemed incorporated
by reference in any filing with the Securities and Exchange Commission under the
Securities  Exchange  Act of 1934 or the  Securities  Act of 1933,  whether made
before or after the date hereof and irrespective of any general incorporation by
reference  language  in any  filings,  unless  expressly  set forth by  specific
reference to this filing.

     The press  release  includes  information  on free  cash flow and  earnings
before  interest,  taxes and  amortization,  or "EBITA".  These measures are not
based on any  standardized  methodology  prescribed by U.S.  generally  accepted
accounting  principles  ("GAAP") and are not  necessarily  comparable to similar
measures presented by other companies. Free cash flow is calculated by excluding
capital  expenditures from GAAP cash flows from operations.  EBITA is calculated
by  excluding  net  interest  income,  income tax  expense and  amortization  of
intangible assets from GAAP net income.  These measures should not be considered
in isolation or as a substitute for measures  prepared in accordance  with GAAP.
Management  believes that EBITA as well as free cash flow are useful measures of
performance as they provide its investors with additional methods for evaluating
its operating performance and liquidity and reflects the resources available for
the Company to invest in acquisitions or to repurchase stock.
