The monthly volume of searches entered on keywords can be found with a few different methods. If you have a Google AdWords account, you can use Keyword Planner for this step. If you don’t, there are a few free sites out there that will give you similar numbers. Obviously, if a keyword has higher monthly searches you’ll want to keep it in mind. However, that also might mean that it has a higher keyword difficulty, and fiercer competition.
Paid Search (PPC): Paid search results are advertisements. A business pays to have their ads displayed when users do a search containing specific keywords. The ads are typically displayed above and to the right of organic search results. The exact placement of the ads is determined by both a bidding process and quality score. The advantages and drawbacks of paid search are often the opposite of organic listings.
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).
