The company has predicted revenue of between $342m (£220m) and $347m (£223m) for its current quarter, which is at least $13m (£8.4m) short of the $360m (£232m) revenue analysts had predicted.
Although its share price has bounced back to just over $201 (£129), the drop demonstrates fears that the site's pace of growth may be starting to slow so soon after a sharp increase. Last quarter its revenue rose to $324.7m (£208.8m) from $188.46m (£121.19m), a growth of 80% since last year.
The site has recently increased its mobile traffic with a revamp of its mobile site and buying newsreader app Pulse for more than $90m (£58m), but signs suggest that revenue from mobile advertising is not proving as buoyant as that of others in the sector.
LinkedIn is currently adopted a new approach to its mobile advertising and has warned that this could slow its advertising revenue.
The shift from desktop to mobile is an issue other social networking sites have also had to contend with, but in comparison, Facebook reported on Wednesday that mobile advertising now accounted for almost 30% of its advertising revenue.
LinkedIn has previously defied market expectations through its popularity as a recruitment and job-hunting site. However, its earnings predictions suggest it is struggling to maintain the pace of growth.
