The typical Web user might not realize they’re looking at apples and oranges when they get their search results. Knowing the difference enables a searcher to make a better informed decision about the relevancy of a result. Additionally, because the paid results are advertising, they may actually be more useful to a shopping searcher than a researcher (as search engines favor research results).
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).
