Notes

Primary search results are those results that are most likely to be returned for a given search.

Secondary search results are those results provided in the case that no useful matches were returned by the primary search engine.

Directory search results are those results that editors who work for the search engine have reviewed and organized by subject.

Paid search results are those results that advertisers have paid to have listed in a search engine's results.
