Search engine techniques are a set of tools and methods that can be used to find relevant information online. These techniques may help you to find a product, answer a question or solve a problem faster. They can also improve your rankings on search engines.

Discovering, Crawling and Indexing

First, a search engine must find content on the web. This is a task that involves programs, known as spiders or bots, that scour the Internet to find and collect data on each page. This data is then stored for later use.

Next, the search engine must be able to process that information into something the searcher can understand. This is achieved using a set of algorithms that are unique to each search engine.

These algorithms are based on a variety of factors including keyword density, page speed and links. They are designed to give users the best possible results and to help pages and websites achieve higher search engine rankings.

This can be done by following SEO best practice. This includes making sure your title, abstract and images are optimised for the keywords you wish to rank for. It can also include including keywords in alternative text (alt text) on any images that you have included in your articles, which helps the search engine to understand what the article is about.

Another important part of search engine techniques is ‘blended’ search. This means that the search engine will combine traditional text pages with rich media content such as images, videos and maps. This can affect how well your website is ranked and it can also influence the types of content that users see when they view your results page.

It is important to keep in mind that this type of search is only as good as the content on your page. If your page is not optimised for your keywords it can be difficult for search engines to understand your information and this could mean that your site is not ranked highly or is not seen at all.

A lot of work has to go into search engine optimization, so if you want to make your content visible on search engines it is vital that you follow SEO best practice. This will ensure that your pages can be crawled and indexed, so that they are shown when people search for your products or services.

The search engine must then be able to find the content that matches your query, ideally within a few clicks of you typing your search term into the box. This can be done via a number of different techniques, including natural language processing and machine learning, which can translate your words into terms that relate to the search engine’s database.

Once the search engine has a list of pages it has identified, it must then decide which ones are the most relevant to your search query. This is a complicated process that is different for each search engine.
