The term "SEO" is the abbreviation to "Search Engine Optimization". This is not about optimizing search engines, though. It is about optimizing websites for search engines. But why one needs to optimize a website? To answer this question we need to understand what a search engine is.

Search engines as the way to find an info on the web appeared in the middle of 90's. They crawled websites and indexed them in their own databases marking them as having one or another keyword in its content. Thus, when someone put some query in the search box of that search engine, it quickly searched its database and found which indexed pages corresponded to that query.

Search engines

Before we start talking about search engine optimization we need to understand how search engines work.

Basically, each search engine consists of 3 parts:





A search engine crawler is a program or automated script that browses the World Wide Web in a methodical manner in order to provide up to date data to the particular search engine. While search engine crawlers go by many different names, such as web spiders and automatic indexers, the job of the search engine crawler is still the same.

Crawlers are very active, and often account for a great deal of the visitors to websites all over the internet. The Google crawler, known as Googlebot, is particularly active, and will often visit a website several times a day, checking for updates or new information. Studies have shown that it is much more active than other crawlers, the closest being the Yahoo crawler, which is about half as active as Googlebot.


-The Indexer. This module stores all the pages crawled by the spider in a large database called the index. Think of it as the index in a paper book: you find a word and see which pages mention this word. The index is not static, it updates every time the crawler finds a new page or re-crawls the one already presented in the index. Since the volume of the index is very large it often takes time to commit all the changes into the database. So one may say that a website has been crawled, but not yet indexed.

Once the website with all its content is added to the index, the third part of the search engine begins to work.

-The ranker (or search engine software). This part interacts with user and asks for a search query. Then it sifts millions of indexed pages and finds all of them that are relevantto that query. The results get sorted by relevance and finally are shown to a user.

Google search engine work

Search engines perform several activities in order to deliver search results.

At the simplest level, search engines do two things.

Index information. Discover and store information about 30 trillion individual pages on the World Wide Web. Return results. Through a sophisticated series of algorithms and machine learning, identify and display to the searcher the pages most relevant to her search query. How did Google find 30 million web pages?

Over the past 18 years, Google has been crawling the web, page by page. A software program called a crawler also known as a robot, bot, or spider starts with an initial set of web pages. To get the crawler started, a human enters a seed set of pages, giving the crawler content and links to index and follow. Google’s crawling software is called Googlebot, Bing’s is called Bingbot, and Yahoo uses Slurp.

When a bot encounters a page, it captures the information on that page, including the textual content, the HTML code that renders the page, information about how the page is linked to, and the pages to which it links.

In the process of crawling a site, bots will encounter the same links repeatedly. For example, the links in the header and footer navigation should be on every page. Instead of recrawling the content in the same visit, Googlebot may just note the relationship between the two pages based on that link and move on to the next unique page.

As bots crawl to discover information, the information is stored in an index inside the data centers. The index organizes information and tells a search engine’s algorithms where to find the relevant information when returning search results.

But an index isn’t like a dark closet that everything gets stuffed into randomly as it’s crawled. Indexation is tidy, with discovered web page information stored along with other relevant information, such as whether the content is new or an updated version, the context of the content, the linking structure within that particular website and the rest of the web, synonyms for words within the text, when the page was published, and whether it contains pictures or video.
