Using organic search data through Data Cube you can make your PPC campaign even stronger. You can research keywords that have the highest traffic and use the BrightEdge Recommendations engine to learn the types of sites that people are most likely targeting with specific queries. You can then create content for your PPC campaigns armed with this insight, positioning yourself well for paid search success.
Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
