Additional Notes

With January 2008 data, DNS error searches were added to qSearch reporting. A DNS error search is a search conducted through the address bar of a browser where there may have been a misspelling or typo in the URL or search string entered. In cases where the default search engine attempts to make sense of the user’s query and returns valid search results based on the interpretation of the query, those searches are qualified as DNS error searches. The inclusion of these DNS error searches may have had a very minor impact on search query and share trends compared to previous months.
