Search engine techniques refer to the knowledge and processes that are involved in getting a website to appear on a search engine result page (SERP). While every database and search engine is different, there are many common techniques that can be used to enhance a website’s visibility. These techniques can range from simple alterations to the way searches are phrased to more complex Boolean search engine tricks. Gimmicks that less reputable SEO firms tout may work for only a short time before the search engines’ developers become wise to them and change their algorithms.
Search engines use a complex algorithm to determine what Web content is the most relevant to any given query. A page’s relevance is determined by an analysis of several elements, including the frequency of keywords on the page and how the keywords are positioned within the text. It also takes into account the number and location of links to that page from other sites on the Internet, which is another indicator of a site‘s importance and its ability to draw in traffic.
During the indexing process, pages are identified and placed in an archive based on the search terms that have been entered into the database. Then, when a user conducts a search, the engine scours its archive for pages that match those words and display them on a results page. The search engine may also take into account a user’s location, the language of the search and other factors to determine what pages are displayed for any given query.
There are two main types of search engines: crawler-based and algorithm-based. Crawler-based search engines operate by sending software components, known as spiders or bots, through the World Wide Web to collect information and add it to an online database. The most popular crawler-based search engine is Google, which controls the majority of the Western market; Microsoft Bing is second and Yahoo third.
To make a search engine more efficient, start with simpler keywords and phrases, such as single words or simple phrase fragments. You can then gradually expand your search to more complicated and specific terms. If you’re searching for something that is specific to one particular subject, such as a specific book title, try to be as exact as possible. Place the search term in quotation marks to ensure that the search engine finds it in exactly the form you want, as opposed to finding all Web pages containing the word or phrase without the quotation mark. Alternatively, you can use the AND operator to find information that features both words or phrases and the OR operator to find information that includes either of them. You can also use the NOT operator to eliminate results that feature a certain keyword or phrase, but this is a risky approach because it may exclude important information from your search. Using this technique requires a degree of sophistication to understand, but can help you narrow your search and save time.
