What Does Do in a Search Engine
A search engine is a website that allows users to search for information on the Internet. It uses a set of algorithms to sift through the massive amount of data on the Web to produce a list of websites that match a specific query.
There are many different types of search engines, including Google, Yahoo!, Bing and a few others. However, the basic principles of how they work are similar across all of them.
Crawling – The first step in how a search engine works is to collect all the content that exists on the Web, which it does using small programs called spiders or bots. These crawlers scan the entire contents of a website to find new links to add to their index. They may do this every few days, so it is a good idea to keep your website fresh and up-to-date.
Indexing – The next step is to categorize the pages that have been added to their index. They use a range of criteria, including keywords, content and page speed to ensure that they provide users with the most relevant results.
Ranking – The last step in the search engine process is to select the best result for each search query and show them on the SERP (search engine results page). This process can be confusing, but it is important to remember that your business website should always appear high up in the rankings when someone performs a relevant search.
Keywords – When writing a search for your business, it is important to use the right keywords. This will help you to get the most exposure possible and it also helps search engines understand your content.
Quotation Marks – Search engines will automatically narrow down your results by looking for words in quotation marks. Putting quotes around the word or phrase you are searching for will help to eliminate results that contain only the term in question, and will increase your chances of finding what you’re looking for.
Plus (+) – Adding a + sign before a search term tells the search engine that you want results for words that are close to each other. This is a useful way to filter results by topic or location.
Minus (-) – The minus symbol tells the search engine that you don’t want results for words in a certain order. This is a useful tool when you’re trying to find a specific phrase, like “congressional hearing.”
You can also use special operators such as
XML Sitemaps – Larger websites often submit a special XML sitemap to the search engines, which acts as a roadmap of their website. This means that the search engine can crawl a larger website much more quickly.
Universal or ‘blended’ searches – The search engine will present a variety of content types in the SERP, depending on what the user is looking for. This can include traditional text pages, images and video.
