Interestingly, recruiters spend only 6 seconds reviewing an individual resume!

They spend that time looking at:
Current title / company
Previous title / company
Previous position start and end dates
Current position start and end dates

If you add a picture, they spend 19% of that time looking at the picture, not the information.

Professionally re-written resumes score 60% better on “usability” – they are easier to read.

Professional resumes had less data, were evenly formatted and
were described as “clearer.” They scored 40% better than before a re-write.

Note that the study is commissioned by TheLadders, a professional CV writing company, so the results are clearly interpreted in their favor, but the above points remain valid.
