Every day, millions of people turn to their computers and look for information on the Web via search engines. It’s estimated that more than 350 million English language Web searches are conducted every day.
Statistics from many sources indicate that almost 90% of Internet traffic and are responsible for 55% of e-commerce transactions. Search Engine Promotion has shown to deliver the highest ROI, compared to any other type of marketing, both online and offline. Search engines bring motivated buyers to you and hence contribute to increased sales conversions.
Search Engine Optimization offers an affordable entry point for marketing your website and an effective way to promote your business online. SEO makes for a long-term solution, is your access to sustained free traffic and a source of building brand name and company reputation. How Search Engines Rank Documents A Web page, or document, can contain various kinds of content (as opposed to display or presentation options like sound, animation or frames), some of which is not shown when you view the document in your browser:18
Title – an embedded description provided by the document designer; viewable in the title bar (it is also used as the description of a newly created bookmark by most browsers)
Description – a type of metatag which provides a short, summary description provided by the document designer; not viewable on the actual page; this is frequently the description of the document shown on the documents listings by the search engines that use metatags.
Keywords – another type of metatag consisting of a listing of keywords that the document designer wants search engines to use to identify the document. These too, are not viewable on the actual page Body – the actual, viewable content of the document. Search engines may index all or some of these content fields when storing a document on their databases. (Over time, engines have tended to index fewer words and fields.) Then, using proprietary algorithms that differ substantially from engine to engine, when a search query is evaluated by that engine its listing of document results is presented in order of ‘relevance.’ Because of these differences in degree of indexing and algorithms used, the same document listed on different search engines can appear at a much higher or lower ranking (order of presentation) than on other engines. Google significantly altered the Internet search engine landscape when it first went commercial in 1998. Besides evaluation of the readable text in the document, it added the scoring concept of “Page Rank.” Page rank is a measure of how many other sites link to the target, a measure of the target’s popularity.
For standard searches finding common information, the page rank addition has Proven to be a very successful ranking adjustment (from the standpoint of content value, however, that addition may be of less value). Additionally, some search engines began to alter their results presentations with “paid listings,” wherein advertisers or through a payment of a fee by the target site, higher rankings are presented to users. This approach, while perhaps of financial benefit to the Internet search engine, has been controversial and not as well received by end users.
Though not hard and fast, and highly variable from engine to engine, these factors thus tend to influence greatly the ranking of a document for a given query and a given search engine: 1. Order a keyword term appears – keyword terms that appear sooner in the document’s listing or index tend to be ranked higher.
2. Frequency of keyword term – keywords that appear multiple times in a document’s index tend to be ranked higher
3. Occurrence of keyword in the title – keywords that appear in the document’s title, or perhaps metatag description or keyword description fields, can be given higher weight than terms only in the document body
4. Rare, or less frequent, keywords – rare or unusual keywords that do not appear as frequently in the engine’s index database are often ranked more highly than common terms or keywords
5. Page rank – the popularity of the target document. 6. Paid listing – an “artificial” boost to document rankings. The specifics of these algorithms are very important because most users tend to focus only on the first results page of candidate documents presented by a search engine, and then only to the highest listed results. Some engines attempt to “infer” what you mean in a query based on its context. Thus, the meaning of heart can differ if the context of your search is cardiac disease as opposed to Valentine’s Day. The methods by which these inferences are made are statistically based on the occurrence of some words in conjunction with others. Though useful for simpler queries, such inference techniques tend to break down when the subject of the query or its modifiers do not fit expected query relationships. For commonly-searched topics, this is generally not a problem; for difficult queries, it is a disadvantage to standard full-text indexing. Cottage industries have emerged to help Web site developers place themselves higher in the search engines’ listings (it is clearly more valuable to be within the first few listings sent to a user than be buried hundreds, or thousands, of documents lower).
A constant battle is being waged between the engines and those desiring high listings from jimmying the system to “unfair” advantage. Crude, early attempts to “spam” search engines to get higher listings included adding hidden terms like “sex” that were searched frequently but not the real subject of the document. Other techniques were to use certain keywords repeatedly, such as “cars cars cars cars cars” to get a higher frequency rating. Another was to cram the page with high-interest terms using the same color as the overall Web page, thus “hiding” the added keywords. The leading search engines have caught on to these and now have automated ways to prevent the worst of these spamming techniques. More subtle techniques, however, are hard to prevent. For example, a listing for ski resorts in Utah could also add hidden tags for “Caribbean” or “beach resort” knowing that wealthy CaribbeanUtah ski resorts. It is because of such techniques (among others) that you can sometimes get document listings from a search that seemingly have nothing to do with your query. So, differences in how search services rank documents, how developer’s themselves choose to characterize their Web documents, and just simple errors in how computers process and index these pages can all lead to highly variable ranking results from different search services. travelers may also be looking to take ski vacations. If you as the searcher asked for Caribbean vacations you may logically wonder why you’ve gotten a listing for.
