However, in popular usage, it is frequently equated with paid advertising strategies such as payperclick (PPC) campaigns.

SEO specialists examine changes in organic traffic over time, typically looking for trends that indicate the positive impas of their strategies. Unlike SEM results, which can be seen almost immediately, the fruits of SEO efforts might take months to manifest.
