How do search engines work? There are three key steps to how most search engines work: Crawling - search engines use programs, called spiders, bots or crawlers, to scour the internet. They may do this every few days, so it is possible for content to be out-of-date until they crawl your website again. Indexing - the search engine will try to understand and categorise the content on a web page through 'keywords'. Following SEO best practice will help the search engine understand your content so you can rank for the right search queries.
Ranking - search results are ranked based on a number of factors. These may include keyword density, speed and links. The search engine's aim is to provide the user with the most relevant result. But by following search engine optimisation SEO best practice you can ensure that: Search engines can easily crawl your website.
You can also prompt them to crawl new content. Your content is indexed for the right keywords so it can appear for relevant searches. Your content can rank highly on the SERP. The omnibox allows users to type in a URL or a search query. You can also visit one of the major search engines' home page to perform a search.
The search engine for a website is at the top or side of each page on a well-designed website. For example, on Computer Hope, our search is at the top and bottom of every page.
Using a website search engine shows you results only from that website and not the entire Internet. Also, some companies may have additional features to make using their search easier. In our case, we use a custom technology called Hopebot that helps direct visitors using our search. Because large search engines contain millions and sometimes billions of pages, many search engines display the results depending on their importance.
This importance is commonly determined using various algorithms. As illustrated, the source of all search engine data is collected using a spider or crawler that visits each page on the Internet and collects its information. Once a page is crawled, the data contained in the page is processed and indexed. With all its features that include sophisticated algorithms, effective crawling, indexing, and ranking, Google provides excellent search results not only within its own search engine, it powers some other search engines as well e.
Bing is the second largest search engine. Although it is impossible to compare Bing as a real opponent to Google with only 2 — 3 percent of the overall search engine market share, it is still a great alternative for those who would like to try something different.
Microsoft Bing is in many ways similar to Google, providing search result types like images, videos, places, maps or news. Although Bing uses the fundamental principles of search engines crawling, indexing, ranking it also uses a special algorithm called Space Partition Tree And Graph which is based on the vectors for categorization of information and for answering the search queries.
Once a very popular and dominant search engine, Yahoo was dropping in value over the years and became somewhat overshadowed by Google. Although it has less than 1 percent of the overall search engine market share, it is one of the most popular search engines in countries like Russia with over 60 percent of all searches in the country , Turkey, Ukraine or Belarus.
Baidu is the most dominant search engine in China. Even though its overall worldwide market share is barely 1 percent, it represents over 80 percent of the market share in China with billions of searches every day. Baidu is similar to Google in many ways. It provides classic blue links with green URLs and shows rich results the same way as Google does. Google, as a search engine, has been a leader in its industry for years and is still dominating the search engine market.
Every search engine uses different complex mathematical formulas to generate search results. The results for a specific query are then displayed on the SERP. Search engine algorithms take the key elements of a web page, including the page title, content and keyword density, and come up with a ranking for where to place the results on the pages.
