1. Introduction:
You are always asking google questions, searching for this and that. -But come to think of it, how do search engines find perfect answers to your questions. Is it by magic, i mean how? Simple. Search engines use smart technology to explore the internet, they organize information and show you the best results. Search engines make sure they give their users what is best for them. In this guide therefore, we’ll explain how search engines work to deliver exactly what you’re looking for when you search.
2. What Are Search Engines?
Search engines are tools that help you find information on the internet. We have google, Yahoo, Bing, Chrome, Opera-mini etc. When you type something into a search engine like Google, it quickly looks through millions of web pages to find the best matches for your question. It delivers exactly what you asked for.
3. 5 Top Ways Search Engines Find What You Are Looking For.
1. Crawling: The Search Engine’s Scavenger Hunt.
First and fore most, search engines use special programs called “crawlers” spiders or “bots”. Spiders explore a site. If your site is linked to various pages (internal and external links), its very easy for crawlers to find your site. Crawlers only crawl to and find a site if it is linked to other pages. Crawlers then follow those links, they explore the site and gather all information about that site.
E.g. If you search for the “latest books to read”, the crawlers visits websites with books to read and notes what is on those pages. This whole process is what we are calling crawling.
2. Indexing: Making a Big List.
Secondly, after collecting information from the web, search engines organize and store it. The process of storing and organizing information is the one we are calling “indexing”. This process is like creating a long list of all information found. An “index” then is that huge database where that information is sent and stored.
To understand better, we can refer an index to a “big notebook” where google writes down all details about each web page it visited.
3. Ranking: Deciding What’s Most Useful Using Algorithms.
Now, at this stage, the search engines needs to figure out. 1.-which web pages are the best to show its users or rather, which web pages match your query? Ranking is the process a search engine uses to determine which web pages are most relevant and useful for your search.
It will look at the factors for ranking like,-
- which keywords match your search,
- which pages have quality content,
- which pages have easy user experience,
- which pages have original content? etc.
Search engines do all this with the help of “Algorithms”. Algorithms are like analyzers. They analyze, sort a lot of data so quickly, then they decide which one should appear at the top of the search engines.
This means that if you type in for example, “the best schools in Uganda”, the search engine will show high ranking schools at the top. This is done by the algorithms as per their ranking factors.
4. Showing Results: Delivering What You Need.
Once the search engine has decided which pages are best, it shows them to you in a list. The top results are what it thinks will be the most useful based on your search. Remember the search engines always makes sure they deliver what is best for you the user.
5. Personalization: Tailoring to Your Preferences.
At this point, search engines deliver what you exactly searched for. If you typed in “best bible verses”, it will bring for you just that. Search engines try as much as they can to give you results that fit your personal interests and past searches. This means you might see results that match what you’ve looked for before.
Conclusion.
Search engines therefore use crawlers to explore the web, create a big list of information, and then use special rules to show you the best results. All of this happens so fast. They give you exactly what you’re looking for right away.
