Comparing rates of growth doesn't tell the whole story. AJ is coming from the basement in terms of market share, while Yahoo has a much larger audience. 19% of a small number is smaller growth (expressed as actual numbers) than 13% of a significantly larger number.
AJ is fond of quoting percentages as it shows their business in a better light.
Here are some more figures, some from their recently released 8K form:
Revenues for the quarter ended March 31, 2004 were $39.2 million. These
first quarter results represent 73 percent growth over revenues of
$22.7 million for the comparable year-ago quarter.
Revenues for the quarter ended December 31, 2003 were $31.8 million. These fourth quarter results represent 58 percent growth over revenues of $20.2 million for the comparable year-ago quarter.
So, revenue growth for Q4 2002 and Q1 2003 was fairly low, a growth of $2.5 Million. This is the low year over year hurdle AJ is comparing itself to.
Quarter over quarter growth is $7.4 million.
