Last week we reported on the apparent traffic spike at person-to-person lender Prosper. Compete's Snapshot showed Prosper with 1 million unique visitors in March.

Based on that observation, Compete dove into the Prosper numbers and found that the domain had not yet been added to its more rigorous monitoring system, and in fact, there appeared to be some panel bias in the original March traffic numbers. Under Compete's revised assumptions, Prosper's March traffic estimate is a third less, just under 700,000 visitors, instead of 1-million plus. 

Also, Compete has now released its April estimates and found that Prosper's traffic declined 25% to 500,000 visitors. While that no longer puts Prosper at the same level as Suntrust, the lender does have considerably more visitors than the nation's 23rd largest bank, Comerica (see revised traffic chart below, Prosper is the blue line).
