A Guide To Search Engine OptimizationHow To Boost The Rankings Of Your Websites |
6. Sponsored LinksSponsored Links Search results appearing under the heading "Sponsored Links" are provided by Google®, a third party provider of pay for performance search listings. Google generates highly relevant sponsored results by allowing advertisers to bid for placement in this area based on relevant keywords. These results, which are powered by Google's advanced algorithms, are then distributed across the Internet to some of the world's most popular and well-known Web sites, including Teoma.com and Ask Jeeves. Other factors Boolean Searching Limited Boolean searching is available. Teoma defaults to an AND between search terms and supports the use of - for NOT. Either OR or ORR can be used for an OR operation, but the operator must be in all upper case. Unfortunately, no nesting is vailable. Proximity Searching Phrase searching is available by using “double quotes” around a phrase or by checking the "Phrase Match" box. Teoma also supports phrase searching when a dash is used between words with no spaces. Until Nov. 2002, Teoma's help page stated that "Teoma returns results which exactly or closely matches the given phrase" which meant that not all phrases matches will necessarily be accurate. As of Nov. 2002, that appears to have been corrected and phrase searching now works properly. Truncation No truncation is currently available. Case Sensitivity Searches are not case sensitive. Search terms entered in lowercase, uppercase, or mixed case all get the same number of hits. Stop Words Teoma does ignore frequently occurring words such as 'the,' 'of', 'and', and 'or'. However, like at Google, these stop words can be searched by putting a + in front of them or by including them within a phrase search. Sorting By defaults, sites are sorted in order of perceived relevance. They also have site collapsing (showing only two pages per site with the rest link via a “More Results” message. There is no option for sorting alphabetically, by site, or by date. Display Teoma displays the title (roughly first 60 characters), a two line keyword-in-context extract from the page, and the beginning of the URL for each hit. Some will also have a link to "Related Pages" which finds related records based on identifying Web communities by analyzing link patterns. Two other sections displayed are the "Refine" section (formerly folders) that suggest other related searches based on words that Teoma uses to identify communities on the Web and the "Resources: Link collections from experts and enthusiasts" (formerly "Experts' Links") which are Web pages that include numerous links to external resources – meta sites or Internet resource guides. Some "Sponsored Links" may show up at the top. These are ads from the Google AdWords program. Teoma will only display 10 Web page records at a time; however, up to a 100 at a time can be displayed through a change in the preferences and on the advanced search page. Teoma may also display up to 10 metasites under the "Resources" heading and up to 6 Refine suggestions. Inktomi is one of the most popular crawler based search engines. Inktomi is a crawler-based search engine. However, it does not make its index available to the public through its own site like other crawler-based search engines, such as Lycos or Alltheweb. Inktomi licenses other companies to use its search index. These companies are then able to provide search services to their visitors without having to build their own index. It uses a robot named Slurp to crawl and index web pages. Slurp – The Inktomi Robot Slurp collects documents from the web to build a searchable index for search services using the Inktomi search engine, including Microsoft and HotBot. Some of the characteristics of Slurp are given below: Frequency of accesses Slurp accesses a website once every five seconds on average. Since network delays are involved it is possible over short periods the rate will appear to be slightly higher, but the average frequency generally remains below once per minute. robots.txt Slurp obeys the Robot Exclusion Standard. Specifically, Slurp adheres to the 1994 Robots Exclusion Standard (RES). Where the 1996 proposed standard disambiguates the 1994 standard, the proposed standard is followed. Slurp will obey the first record in the robots.txt file with a User-Agent containing "Slurp". If there is no such record, it will obey the first entry with a User-Agent of "*". This is discussed in detail later in this book. NOINDEX meta-tag Slurp obeys the NOINDEX meta-tag. If you place in the head of your web document, Slurp will retrieve the document, but it will not index the document or place it in the search engine's database. Repeat downloads In general, Slurp would only download one copy of each file from your site during a given crawl. Occasionally the crawler is stopped and restarted, and it re-crawls pages it has recently retrieved. These re-crawls happen infrequently, and should not be any cause for alarm. Searching the results Slurp crawls from websites to the Inktomi search engines immediately. The documents are indexed and entered into the search database in quick time. Following links Slurp follows HREF links. It does not follow SRC links. This means that Slurp does not retrieve or index individual frames referred to by SRC links. Dynamic links Slurp has the ability to crawl dynamic links or dynamically generated documents. It will not, however, crawl them by default. There are a number of good reasons for this. A couple of reasons are that dynamically generated documents can make up infinite URL spaces, and that dynamically generated links and documents can be different for every retrieval so there is no use in indexing them. Content guidelines for Inktomi Given here are the content guidelines and policies for Inktomi. In other words, listed below is the content Inktomi indexes and the content it avoids. Inktomi indexes: ? Original and unique content of genuine value ? Pages designed primarily for humans, with search engine considerations secondary ? Hyperlinks intended to help people find interesting, related content, when applicable ? Metadata (including title and description) that accurately describes the contents of a Web page ? Good Web design in general Inktomi avoids: ? Pages that harm accuracy, diversity or relevance of search results ? Pages dedicated to directing the user to another page ? Pages that have substantially the same content as other pages ? Sites with numerous, unnecessary virtual hostnames ? Pages in great quantity, automatically generated or of little value ? Pages using methods to artificially inflate search engine ranking ? The use of text that is hidden from the user ? Pages that give the search engine different content than what the end-user sees ? Excessively cross-linking sites to inflate a site's apparent popularity ? Pages built primarily for the search engines ? Misuse of competitor names ? Multiple sites offering the same content ? Pages that use excessive pop-ups, interfering with user navigation ? Pages that seem deceptive, fraudulent or provide a poor user experience Inktomi's policies are designed to ensure that poor-quality pages do not degrade the user experience in any way. As with Inktomi's other guidelines, Inktomi reserves the right, at its sole discretion, to take any and all action it deems appropriate to insure the quality of its index. Inktomi encourages Web designers to focus most of their energy on the content of the pages themselves. They like to see truly original text content, intended to be of value to the public. The search engine algorithm is sophisticated and is designed to match the regular text in Web pages to search queries. Therefore, no special treatment needs to be done to the text in the pages. They do not guarantee that your web page will appear at the top of the search results for any particular keyword.
