US online job ads fell by 45,800 in June to approximately 4.76 million, according to The Conference Board’s report on online job ads released today.

The Conference Board’s measure of online job ads is aimed at tracking demand for labor. However, the organization noted there has been a declining trend in the number of online job ads that may not reflect the broader trend in the US labor market. “Based on changes in how job postings appear online, The Conference Board is reviewing its [help wanted online jobs] methodology to ensure accuracy and alignment with market trends," the organization said.

Using data from the current measure, seven of the largest 10 online occupational categories posted decreases in June.

Healthcare practitioners ads posted the largest loss, down by 27,700 to a total of 614,700. They were followed by business and finance ads, which fell by 16,300 to 282,300.

Food preparation and serving-related ads posted the largest gain, up by 23,300, followed by transportation and material moving ads, with a gain of 6,300.
