It’s that time again: April comScore qSearch data are coming out tomorrow. But the financial analysts are releasing it first to their clients and others who’ve subscribed to their missives.

According to our source, comScore will report that both Google and Bing have made small, incremental gains since last month and seen modest growth since last year. One or both are growing, it appears, at Yahoo’s expense. AOL and Ask are basically flat.

Yahoo is at its lowest point to date and has recorded its eighth straight monthly decline in terms of market share. Our source believes that Yahoo’s share could sink quite a bit lower over time.
