When specific people, places, and things show up in queries or in web pages, that can be a signal to search engines to do something special in the results that they show. How prepared are you to understand and anticipate how the search engines treat them? Do you have a strategy in place?
Named entities show up in a lot of queries – they may even be one of the kinds of things that people look for most online. In a 2010 white paper from Microsoft, Building Taxonomy of Web Search Intents for Name Entity Queries (pdf), we are told how large of a role that “named entities” play in search:
According to an internal study of Microsoft, at least 20-30% of queries submitted to Bing search are simply name entities, and it is reported 71% of queries contain name entities.
Within the announcement Google made earlier this year about the Hummingbird update is the search engine might rewrite queries, substituting some terms within them, when they think doing so might improve the results that searches see, and a very recent Google patent describes how Google might use a data driven approach to explore how effective those substitutions might be.
There is a history of Google making changes to queries and results to try to provide better search results.
Titles – In January of 2012, a Google Webmaster Central blog post told us that Google might sometimes change the title of a page in search results if they thought the new title might lead to more clicks and views of a page. While that might not be what the author of a page intended, it shows that Google is trying to make it easier for people to find the information they are searching for. I’ve run across sites where all the pages had the same titles, but unique main headings, and saw Google add the text for the main headings to those titles for each page.
