When you do not know about something, – for example, the Prehistoric Times – you tend to be curious about it and the desire to know more about that topic bubbles up. Because of this, you ask people who are knowledgeable about the Prehistoric Times. Yes, it has been taught in school, but what if you want to have a deeper understanding of the said time in the History of the world?
If asking another person does not satisfy your craving for the subject, you resort to researching about it in books. However, the most accessible researching tool is the internet. After all, it is called the information superhighway. You type the phrase “Prehistoric Times” in the search engine bar and hit the button “Search.” Viola! Loads tons and tons of information about the said topic emerges on the results page (or SERP – search engine result page).
You might begin to wonder how search engines find the information you are looking for. Well, you do not have to look further because this article will provide you the most vital information about how search engines work.
Basically, search engines do three valuable steps in order to serve you the most relevant and useful articles. These are:
1. Searching the internet.
In this step, the search engines make use of keywords embedded on the articles. This is when an original SEO post becomes important.
The search engine looks for web pages containing the keyword/s in an original SEO post, and then presents the results to you, the researcher. The fun part about how search engines work lies on the fact that the internet has a very large network of servers from all over the world that is also called the World Wide Web. Once you have entered the keyword/s the search engines make use of software robots. These are programs specialized for the purpose of looking for information within millions of web pages. These specialized robot programs are called spiders, and the act of building a list that will be included in a SERP is called web crawling.
2. Building an index of web pages
This is where the cataloguing of pages comes in. For a faster result, the search engine makes an index of what web pages contain materials that relate to a keyword. Therefore, it is a system of filtering useful and relevant contents from unrelated ones.
The search engine, in its attempt to build an index that puts out the most important pages under a certain topic, ranks the web pages according two significant components. One is the information that the article contains, and the other is the quality of the content. Many search engines put high ranks on web pages that have an original SEO post. This means that the keyword in the article is well used and spread, the information is appropriate, and not plagiarized.
3. Establishing a Query
This is a step that enables the researcher to do a much more advanced search. If the results that you have received during the first attempt do not satisfy you, you have the choice to do a more in-depth search for the topic. Many search engines are integrated with Boolean operators that makes you fill up information on what you want to focus on, omit, and include.
The most popular Boolean operators are AND, OR, NOT, FOLLOWED BY, and the use of quotation marks.
- If you want to search for more than words, you need to include the word AND (or a +) between each word.
- OR allows you to search at least one of the words you type in.
- NOT gives you the option to omit a word.
- FOLLOWED BY lets you make sure that one word entails another.
- Quotations marks lets you search for a definite phrase.
These Boolean operators let you make sure that your specifications can be found in an original SEO post included in a SERP.
