Search Results & Search Algorithms

Search Results (delivered in 0.29 secs)

A web search is performed by typing relevant words into a search engine. These words form the search query (also called a keyword phrase KWP or search string). Eg If someone is looking for a house to rent in Sydney they might use the keyword phrase ‘home rentals Sydney ‘.

The search engine then accesses the search index and returns a list of relevant sites in the form of a Search Engine Results Page (SERP). There are often thousands of relevant web pages listed on the results page. For this reason search engine developers created rules for ‘ranking’ the results so they could be listed in order of importance to make it easier for the user to find what they are searching for.

These ‘rules’ are a set of complex calculations called search algorithms.

What is a search algorithm?

Search algorithms assign value to different parts of each web page and then work out an overall score based on how relevant the web page content is to the search query. Some search algorithms also take into account how popular the web page is based on how many other sites link to the page (especially if the linked site is of a similar topic). The best match takes the first spot on the search engine results page. This is often called a No. 1 ranking.

Search algorithms are frequently updated and are different for each search engine. For obvious reasons they are not disclosed however, basic information is published by each search engine in the form of guidelines and recommendations for web page developers.
