US online job ads rose by 81,500 in October to more than 4.56 million, according to The Conference Board’s report on online job ads released today.

The organization has noted 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,” according to the report.

Using data from the current measure, eight of the largest 10 online occupational categories posted increases in October. Transportation ads increased by 32,100 to a total of 340,700.
