Editing Metasearch engine (section)

=== Architecture of ranking ===
Web pages that are highly ranked on many search engines are likely to be more [[Relevance (information retrieval)|relevant]] in providing useful information.<ref name=retrieval/> However, all search engines have different ranking scores for each website and most of the time these scores are not the same. This is because search engines prioritise different criteria and methods for scoring, hence a website might appear highly ranked on one search engine and lowly ranked on another. This is a problem because Metasearch engines rely heavily on the consistency of this data to generate reliable accounts.<ref name=retrieval/>
