Using the Internet but Google did not Google, it is hard to find people! Search for Google in any way is an integral part of our internet life. We go Google so much that there are more search engines in addition to Google - they are not always on our heads! There are many different types of search engines like bing, yahoo, duckduckgo, and their numbers are also not low. The most interesting thing is that almost every one of them has some variation. However, Google is above all in terms of popularity.
Before knowing about how search engines work, what is the search engine? Even though everyone is accustomed to using search engines, the idea is to make it a bit clearer. Simply put, search engine is a type of software system that helps us find information from other sites available at World Wide Web (WWW).
Do you need information on any topic? Soon Google searched Google Open, and in the moment millions of results appeared! Again sometimes it happens, you searched for a wrong word, but Google just corrected it and showed the result! Or you're going to do something that you think is a little about. Put a few words on the guess. But in a short time, Google again came to know about your mind and brought the information to you! It took Google time to get out of these results or to understand your mind less than a second! Billion billionth site of the entire web site, with less than 1 second time to find out the information you have to find out is not a chat! The question is definitely peeping, how is it possible? But we will say, is it possible at all? The readers may think that if the result is not possible, then the result shows! Yes, Google Result is showing up right. But maybe not exactly how you think.
As mentioned earlier, Google is not the only search engine on the web. Each search engine offers services to their customers separately. So a search engine's work will never match with another. However, every search engine follows these steps:
They search the web and share a few, based on the important words.
The words that were found were created and indexed.
They match the wads they have searched with users and their indexes.
Old search engines used to create hundreds of large page indexes. Every day thousands of searches were done in it. But today's search engine indexes millions of pages. And every day, more than a million search results are shown to them. Things look a little complicated? No, not very complicated. Now let's explain these main steps one by one.
Web Crawling
'Web' means 'fake' On the other hand, 'Crawl' - the word 'crawling' of the word Bangla. That means 'Crawling the Web' is straight in Bengali, crawling over the net. But who is this crawling? The answer is 'Spider'! Feeling weird? Yes, that's normal.
When you are searching Google, every time Google shows you results But before showing you the results, Google itself has to find out the results. To do this, search engines create specialized software robots. They are called 'Spider'. It is the work of roaming the whole web and writing everything. Just as the spider roams over its net, as well. This process is called web crawling.
Now the question is, how did Spider start traveling on this web site? It usually starts with some popular travel websites. At first Spider collected the words from these popular pages. At the same time, it also saves where the words are getting from. Then follow the link to other pages on that site. Then go to those pages and follow the other links there. And that's how Spider's travel continued. Whether the spider has been able to access sites within a specific time and no changes have been made. For example, this article has been published, but no one has told Google's spider. But now if you search Google with the title of this writing, then you will see that the result has come out in the result. Although Spider does not know about this article, Roar knows about Bangla but also knows about Bangla. So he naturally entered roar bangla and followed every link to enrich its information store. And there they have also crawled this writing. Whenever a spider goes to a page, notes every word on that page, notes how many times the same word has been used. For example, Google Spider has been created in such a way that it can create indexes for other words in the article, without the words 'a', 'a', 'the'. But there is no such thing that all search engines will follow the same strategy.
Meta Tags
A simple meta tag is a special type of HTML tag that briefly summarizes the content of a page. We all saw the tags on different blogs. Like the meta tag, giving a brief overview of the content. The blog tag gives you an idea of yourself-me. And on the other hand meta tags give this idea the search engine. There can be two or three meanings of a single word in a text! In that case, Meta tags play a very effective role. However, the problem with the use of Meta tags is that often the page owners often put meta tags that do not conform to the original text.
