Trends noted in previous studies regarding onpage technology have become more pronounced.
It appears that it is fundamental for a good ranking to include all onpage factors, especially when
technical parameters of the site are concerned. Search engines do not seem to favor pages that
meet certain onpage criteria; rather the absence of these criteria have a negative effect on the
ranking.
The interpretation of low correlation values, especially with regard to binary features which are
common in an onpage technical approach, must be considered carefully. The average value of the
correlation should be used for each analysis point.
