Although designed for webmasters, search engine users will also find portions of the search engine comparison chart useful in determining how fresh and complete the different search engines are. Full explanations of items can be found immediately below the chart. Also, check out Search Engine Watch's Search Engine Reviews Chart . This chart is as of January 25, 1999. The larger a search engine is, in terms of pages indexed, the more likely pages from your web site will be included.
Actual numbers can be misleading, as explained below.
So, search engines are categorized as big, medium, small or tiny. Below this is the number of pages indexed, in millions. Expect to find most of your pages in a big search engine, some to many of your pages in a medium search engine and few or none of your pages in a small or tiny search engine. See the section about depth, below. The figures shown are the last reported to me or reported elsewhere.
