Losing rank to Scholarly Articles and Keyword Description Stuffing

[ChazSztroin]

I began reviewing the rankings this week and noticed that many of our #1,#2, etc rankings had been bummed down as a whole.  After reviewing many of the search terms it seems Google has begun to rank a group named Scholarly Articles in the #1 position.  Has anyone else noticed this change?

Secondly, many of the rankings we have lost are due to some competitors stuffing their descriptions with keywords.

#1 Rank Description

Failure Analysis; Scanning Electron Microscopy & EDS Analysis. Paint Chip Analysis and Evaluation; Paint Tests Physical Testing of Paints.

#1 Rank Description

NACE certified coatings inspector, paint inspector, coating inspector, coatings inspector, lining, failure analysis, survey, corrosion, rust, evaluation, testing, expert

Is this a possible glitch occurring with the new humming bird release and has anyone else noticed an issue like this?

It dropped our #1 ranks from 37 to 23 overnight.

Thanks
