The number of online job postings last month declined 16.4 percent from a year ago, the Conference Board reported Friday.

In total, there were 2,591,500 new jobs posted online in April, with healthcare and management accounting for more than 450,000.

Alaska continued to lead the online job market last month, followed by Nevada and Massachusetts, while the sharpest declines were reported in Maryland, Vermont, and Connecticut.

Gad Levanon, a Conference Board economist, said online hiring is likely to continue to decline in the months ahead.

"April is the month when we normally see employers increasing their recruitment, but this year it actually declined," Levanon said in a statement.

On Friday, the government reported a net loss of 20,000 jobs in April, down from an 81,000 decline in March.
