Google indexing is an ever-present, ever-burning and, above all, almost always difficult topic.
When optimizing a site, it is important to understand the reason behind the changes that are being made. That is why some of the most common questions among both new and experienc SEO specialists are: “How does Google search work?” and “How does Google list search results?”.
Google Indexing: Here’s How Google Decides If You Exist on the Web (And If Your Site Is Worth Entering)
The answer is difficult even for those in the industry, so when our clients ask us, we try to take them by the hand and guide them into the fantastic world of Search Engine Optimization and Google indexing tools .
It is a complex mechanism, in which everything fits together perfectly but, at the same time, everything is constantly changing. And if there are universal laws, link to the existence of a certain plug-in or the presence of the cart in an e-commerce, other factors are instead very random.
After all, Google is the leader in its field. When a major change is made to Google’s search algorithm or the way results are display, it’s only a matter of time before other search engines follow suit.
This means that even though other search engines may not be as advanc as Google, they operate on the same principles.
So, when a site is optimiz for Google search, those efforts will certainly have a similar impact on other search engines. So, let’s take a look at how Google’s search indexing system works, and how to optimize your site for better search results.
The work of spiders (or crawlers)
Before understanding how Google selects and organizes results, it is important to understand how information about online content is stor and what is behind Google indexing .
The main steps are 3:
- The spider, or rather the “little spiders” that Google sends around the web to look for information, displays our page and extracts the information from the HTML (spiders, because we are online, get it?);
- All pages view by the spider are archiv, when we click “search”, the search is perform in this database;
- The search algorithm is us to scan the pages visit by the spiders to find those with the most relevant content.
Indexing
The next step in this process is Google indexing . When a user searches, Google doesn’t instantly search the web for the most relevant results. Instead, it searches its database of online content: its index.
As you might imagine, this is a much faster process than crawling through the billions of web pages that are online today, which is why Google searches so quickly. (Have you ever notic the X results in 0.X seconds sign?)
When spiders roam the web, their goal is to find new content to add to this index, so that when the user performs a search, they are return the most up-to-date results possible.
From an SEO perspective , the most important thing to know about Google indexing is that if your site is not in Google’s index, it will never be seen by anyone.
It’s the law of natural selection!
How Google Spiders Work
Let’s go back to our cute little monsters. Their technical name is Googlebot, and their mission is to find content bas on an algorithm.
As Google explains, “The programs determine which sites to crawl, how often, and how many pages to fetch from each site.” The process begins with a list of URLs generat by previous searches. Then, as the spider visits the pages, it looks for links and adds them to the list of pages to crawl.

From there, it will start analyzing those pages too, looking for new sites and changes to sites it has already analyz in the past. All of these changes are then add to Google’s index .
Search Results: How Google Lists Websites
When a user performs a search, Google scans its index for relevant results and returns the ones that appear to be the best according to its algorithm.
How does this algorithm work? Unfortunately, we do not know, Google has always been reticent about it. We do know, however, that there are over 200 factors that are taken into account to determine the most relevant pages.
The algorithm is constantly updat, in order to offer the user the best browsing experience.
Here are the services we can offer you for the SEO of your website
What is Google PageRank?
Although Google is very reluctant to explain the factors that underlie its algorithm, it has reveal an important one call PageRank. According to Google, PageRank is “a measure of the importance of a page bas on the links from other pages that point to it.” This is why backlinks play such an important role.
This is one of the few factors that Google has confirm, and it is how the algorithm determines the value of pages and sites. It is also interesting to note that not all links have the same value when it comes to PageRank.
Links from authoritative sites have a much more relevant and positive impact, while, on the contrary, spammy links have a negative impact on the ability to rank well and also to be detect by Google indexing .

The Google Search Algorithm
Since the early 2000s, when Google began to establish itself as a leader in its field, SEOs have begun to pay attention to the words of founders Sergey Brin and Larry Page about the work of the search engine.
As the latter began to become an essential part of online browsing for many users, companies realiz that it was in their best interest to position 9 best wordpress plugins for backup and restore themselves as well as possible in the rankings. At this point, however, achieving that goal also includ finding new ways to exploit Google’s algorithm.
The first change occurr in 2003, with the aleart news first Florida update. These changes were intend to penalize sites that us SEO tactics but did not offer a good browsing experience. This update had such a major impact that it caus protests.
That was the first time sites saw the negative consequences of spammy practices like “keyword stuffing,” and many of the specialists who us those techniques were not at all happy about it.
But in retrospect, that was just the first of many algorithm updates aim at penalizing sites whose owners us tricks that didn’t help users.
It mark a turning point: the goal was now to provide the user with a good experience – a goal that Google continues to pursue.
How does Google search work in 2018?
Since the beginning, Google has focus on guiding users to quality content. Algorithm updates follow this focus.
While it may be difficult to prict exactly what changes are on the horizon for SEO strategy, it is safe to say that they will have the same basic logic of providing users with the best possible service.
Of course, this does not mean that all updates will be the same. While some of these may be aim at penalizing SEOs who use tricks, others will instead provide updates on what should be done.
For example, recent updates have focus on adapting to search trends, prioritizing user security, and making information easier to access.
How Google Image Search Works
While it is true that people search for information on Google, it is also true that visual content has become increasingly important in recent years.
Just like the main search engine, Google’s image search option operates on a complex algorithm design to return the most relevant images to users.
However, spiders cannot see images the same way we do, so they rely on the file name, alt text, and context to index them correctly. So if you want your site’s images to show up in Google Image Search, these elements ne to be optimiz.
First, you ne to rename your files in a logical and informative way. Many photos have a default name of “IMG0001.jpg”: this tells crawlers nothing about the content of the image. It is therefore important to take the time to name your images accurately and accurately.
If you want an image to rank well in Google, you ne to include not only the concept, but also the entire context. “Puppy” is one thing, “Dalmatian puppy playing with a ball” is another matter entirely. In short, it is better to include everything that can help the search engine decipher the image.
What can we do?
Google’s algorithm is a bit like the formula for the elixir of long life: everyone wants it. If we knew all the factors taken into account, we could jump to the first place in every search in no time.
That being the case, it is our job to do the best we can for our customers. And we do that by staying up to date with how Google operates, trying to produce quality content, paying attention to images, link authority, and more.
But that’s another story… Next week we’ll tell you how to get a good position in Google’s ranking.
