Custom Search
Keywords, or key phrases, are what a user enters into a search engine query to find web sites. Both SEO and PPC advertising involve selecting the keywords that are relevant to a company’s web site and are used by potential customers. SEO aims to have a web site rank in the natural results for its target keywords. In PPC advertising, the advertiser bids on desired keywords to achieve rankings in the paid results.
