Advantages and Disadvantages of Meta-Search Engines

  • You can get results from multiple search engines without having to visit each one. It gives your search a broader scope to look at, since each search engine's index differs from each others.


  • May need to decode query forms.
  • Translations of query syntax and fields not exact.
  • Some sources don't sort by relevance.
  • No way to compare relevance.
  • Vulnerable to search spam.
  • Results returned as HTML without useful tagging, require screen scrapping.
  • Variable quality of search engines.
  • Must keep up with changes in source engines.
