Google represents a great business model, that invests billions of dollars in products such as Gmail, Google Search, Google Maps, Google Earth, Google Apps and more. Google earns money that come from paid applications that users purchase, and for them to buy it and to use it, they must trust this brand.

To show their clients that they are a reliable company, Google tries to satisfy every user`s need through the apps they develop. Over time, they have done a tremendous job regarding this subject.

How does Google search engine work, exactly?

In the first stage, Google scans the Internet through a range of programs to find new pages and sites in order to index them. Also, anyone can send a file called sitemap to Google, which helps to speed up the process. The indexing process involves Google bots scanning the page, who find out what the site is about and rank it according to the content they found. In the past, this procedure took up to 30 days, but now, the method has been improved and each time news and sites appear, Google indexes them pretty quickly.

In the second stage, Google sends users to the site to test the indexing. For example: if Google suspects that a newly created site has to do with gadgets after he scanned the content of this site, then for a period of time (between 3 and 6 months) it will occasionally list it higher in the search results for users to access it. After that, Google will observe how the users interact with the site, because only so the search engine can tell if the site is relevant or not for the users and will rank it accordingly.

If the site was useful to those who have visited it, then Google will memorize the search term and it will place a little higher for the word categories used, namely "gadgets". Also, if the site is optimized, Google will place it in other word categories from the same group of interest, such as "new gadgets", "cheap gadgets". Therefore, an optimized website will be positioned higher in several word categories. If the site isn`t helpful for the users, at least Google will know that it isn`t a good site to suggest for that category of words used.

How Google ranks a page/site?

Google tries to balance all sites, both new and older ones and tries to rank them according to what the user is looking for. But things are not so simple, given that Google uses about 200 different ranking factors to provide the best results to his users.

Some of the known ranking factors are:

1. The type of the content (how relevant is the information on the site for the search terms)

2. The quality of the content (spelling check is used to separate professional sites from unexperienced and beginner sites)

3. The novelty of the content (websites with content dating back a long time ago are less likely to be returned in a Google search)

4. The region the user is from

5. The legitimacy of the site (if the page is considered spam or not)

6. The name and the address of the site

7. Synonyms for the keyword

8. Social media campaigns

9. How many links refer to a webpage

10. The value of these links

Google is the first in the search engines top, with 40,000 searches per second. With millions of people that turn to Google to shop and to find solutions, we must understand how Google searches work. Google results page is the page that appears after a user types a question on the Google search page. Next, we will discuss the types of results that Google offers.

There are 3 types of Google search results:

1. Organic search results

Organic results are those sites that Google believes to be the most interesting and relevant for the user, based on their search. As I said above, Google uses a complex algorithm to determine which sites to list on the first search results page.

2. Local search results

This section of Google is very important, because it uses the person`s location to display the search results page solutions and services that are close to the user. For example, if a user searches 'pizza restaurants sector 3", the local results section will show three pizza restaurants located in the area where the person is located, along with the restaurant's rating, address and hours of operation.

3. Paid search results

When you type a search on Google, you probably noticed that the search results that are located at the top and bottom of the page are labeled as ads. This section is known as Google AdWords or PPC (pay-per-click) online advertising.

Every business owner can have an ad listed in this section by creating an account on Google Adwords, writing an ad and setting the price he will pay for that ad. Then, Google determines which ads it ranks, depending on the quality and relevance of the ad and how much the person who created it pays, compared to other competitors on the same keywords.

For example, if someone owns an Italian restaurant in Bucharest, a few keywords to bid on would be "Italian restaurant Bucharest", "Italian restaurant 3rd district" and / or "Italian restaurant burrata". When someone searches these keywords, that certain ad is more likely to be displayed.

Google's success depends on the trust that clients offer it. To keep that trust, credibility ferociously defends Google. If it finds a site that ranks well, but doesn't provide relevant and quality information to the users, Google will display the site lower in the search results page. The goal of Google is to improve the quality of websites found in the World Wide Web and to offer users quality and relevant content in order for them to pay for the provided services.
