Professional services firms generating 40% or more of their leads online grow 4 times faster than those with no online leads, according to [pdf] a November 2011 study from Hinge Marketing.
Data from “Online Marketing for Professional Services Firms” indicates that the median 2-year growth rate was highest (63.9%) among the firms surveyed generating 40-59% of their leads online, followed closely by those generating 80-100% of their leads online (60.7%).
Firms that did not generate any leads online grew at a median rate of only 15%. The study notes that given the potential of very large and very small firms to skew the results, median values were selected as the most stable measure of central tendency.
Among the survey respondents, over 77.1% generated some new business leads online. 48.1% reported generating less than 20% of total leads online, while about 14.8% generated 40% or more.
