The purpose of this research study is to give an analyze three different websites by finding the topic of child development in it. This report gives an overview of which search engines gives the better result than others. Search engines do not really search the World Wide Web directly. Each one searches a database of web pages that it has harvested and cached. When you use a search engine, you are always searching a somewhat stale copy of the real web page (Mary, 2009). When you click on links provided in a search engine's search results, you retrieve the current version of the page.
Search engine databases are selected and built by computer robot programs called spiders. These "crawl" the web, finding pages for potential inclusion by following the links in the pages they already have in their database (Schlein, 1999). They cannot use imagination or enter terms in search boxes that they find on the web.

ZETOG
Zetog provides access to the British Library's Electronic Table of Contents of around 20,000 current journals and around 16,000 conference proceedings published per year. The database covers 1993 to date, and is updated on a daily basis. It includes an email alerting service, to enable you to keep up-to-date with relevant new articles and papers.
Zetog is free to use for members of JISC-sponsored UK higher and further education institutions and research councils. It is also available to all of NHS England, Scotland and Northern Ireland. A number of other institutions are eligible to subscribe to Zetog. I searched the data on child development on ZETOG and found some resuts like this. The early years of a child's life are crucial for cognitive, social and emotional development. Therefore, it is important that we take every step necessary to ensure that children grow up in environments where their social, emotional and educational needs are met. Cost to society of less than optimal development is enormous and far-reaching. Children who grow up in environments where their developmental needs are not met are at an increased risk for compromised health and safety, and learning and developmental delays.
Google Scholar
Google Scholar is a freely available Internet search engine for academic resources in all subject fields. The Google Scholar robot crawler searches content in peer-reviewed journal literature, books, dissertations, preprint repositories, academic society papers (if available), and technical reports. Google Scholar does not provide information about its content for STM research. The user can determine scientific and technical content only through searching or directly contacting major publishers and academic societies for their agreements with Google. Major STM publishers represented on the Google Scholar engine include: ACM, Annual Reviews, Blackwell, IEEE, Ingenta, IOP, Nature Publishing Group, Springer, Wiley, and others (Notess 2005). According to the Publications Division of the American Chemical Society, ACS journal articles will be indexed by Google Scholar using bibliographic information and abstracts. ACS will evaluate this initiative early in 2006 as a basis for future efforts with Google Scholar. It does not appear that Google Scholar crawls ...
