Preface
Search engines are constantly evolving over time. Annually new methods are introduced as SEO requirements and other methods are updated due to Google updates.
SEO, meanwhile, is being used by SEO experts and webmasters as a tool to combat search engines. They know that SEO can get more traffic and higher rankings in search results.
But what is the truth of this story? How exactly do search engines work?
In this article, we will comment on today’s search engines and provide a list of rules related to search engines. We will also explain our understanding of how the search engine works and why it is essential to use a combination of search tactics to succeed.
How do the search engines work?
Search engines organize a number of activities to provide search results.
Crawling
The process of retrieving all Web pages linked to a website. This task is done by software, called a robot or spider or Google bot, in the case of Google.
Indexing
Create an index for all extracted Web pages and keep them in a giant database from which it can be retrieved later.
Processing
When a search request arrives, the search engine processes it, that is, it compares the search query search string with the indexed pages of the database.
Calculation of relevance
It is likely that several pages contain the search string. The search engine begins to calculate the relevance of each page of its index in relation to the search string.
Retrieving Results
The final step in search engine activities is to extract the best results. Basically, it’s just about displaying them in the browser.
To engineer a search engine is a challenging task. Search engines index tens to hundreds of millions of web pages involving a comparable number of distinct terms. They answer tens of millions of queries every day. Despite the importance of large-scale search engines on the web, very little academic research has been done on them.
Furthermore, due to the rapid advance in technology and web proliferation, creating a web search engine today is very different from 3 years ago. This page provides a summary description of our large-scale web search engine .the first such detailed public description we know of to date.
Search engine algorithms
The search engine algorithms, which are unique to each search engine and just as important as the keywords, are the reason for and how search engines are ranked. Basically, a search engine algorithm is a set of rules, or a single formula, used by the search engine to determine the meaning of a web page.
Each search engine has its own set of rules. These rules determine whether a web page is real or spam if it contains important data of interest to people, and many other features to classify and list the results of each request. the search started, to perform an organized and informative search.
engine results page. Algorithms, as they are different for each search engine. Algorithms are also well-kept secrets, but there are some things that all search engine algorithms have in common.
1. Relevance
One of the first things that a search engine algorithm verifies is the relevance of the page. Whether searching for keywords or seeing how these words are used, the algorithm will determine:
if this webpage is relevant to a particular keyword.
2. Individual Factors
The second part of search engine algorithms is individual factors. they differentiate this search engine from all other search engines. Each search engine has unique algorithms. they have the individual factors of these algorithms explain why a search query produces results differently.
3. Off-page factors
Out-of-page factors are another part of the algorithms that remain specific to each search engine. So Off-page factors are things such as click metering and linking.
Search engine algorithms are the mystery behind search engines, sometimes even amusingly called the “secret sauce” of the search engine.
Conclusion
A search engine is a software, generally consulted on the Internet, which makes it possible to search an information database according to the request of the user. The engine provides a list of results that best matches what the user is trying to find. Today, many search engines are available on the Internet, each with its own capabilities and features.
