SEO is one of the best and the fastest way to get your online business visitors. Some tools will help you understand the working principle of SEO. You will explore this from the web, or any blogs on search engines.

What are Spiders or Crawlers in Search Engine

They are known as ‘bots’ which are used by the search engines algorithm to browse and scan the whole worldwide web to find out new websites and their pages to link to their index. For spiders to do this effectively the websites are easily crawlable is very necessary. Websites that have poor URL structures, broken links, duplicate content, etc. may cause spiders not to index on the search engines. As a result it might not be visible on the search engines for your sites.

The spider bots will also observe and check the contents of the page to see if it’s suitable to appear on the search engine. It will also measure what kind of keywords it will show for.

What are Keywords

Using any search engine we have to enter a keyword into the search bar and it will provide a list of results. How a search engine determines finds out for any keyword is a very complex and complicated process. The primary and first process is to find out the relevancy of a keyword by knowing its character. After that the search engines will crawl your website for the specific related keywords. By this way search engines calculated which page should appear for specific keywords used for search.

Say, for instance, you have a piece of content on your web that speaks of a certain jacket. When this is made clear in the website then the search engine will be able to crawl the website, see what the page is about, and determine firstly how it will index the page, and secondly, how high it will appear in the search results for the keyword ‘jackets’ and any other keywords relevant.

Such engines are text-driven and so look at a website’s text objects to get an idea of what it’s about. This is called ‘crawling.’ Technology can advance rapidly but search engines are not “intelligently” evolved creatures to appreciate the beauty or look and feel of a website or to enjoy the images and sounds in flash movies. Search engines work differently from each other, so ‘conquer’ all of them in search results is quite a challenge, but cautious so smart optimization will work wonders.

Search engines are going through a whole series of processes starting with ‘crawling.’ They have to carry out multiple concurrent tasks to produce search results as close as possible to the customer, who is a human searcher.


A program called a spider or crawler bot which follows pages of links and indexes what they find in their crawling. However, visiting every single web page to extract information is practically impossible for the crawler, often several web pages end up not being ‘crawled’ for months, which is why visualizing what a crawler might see and just placing those on the website instead of flash movies, password-protected pages, comprehensive directories, and JavaScript frames is essential. If the content can not be accessed there is no possibility of it being indexed, stored or retrieved. It is easy to find if the website content is viewable to a spider using a Spider Simulator.


The contents are indexed and stored in a massive database after the webpage is crawled. The ‘indexing’ method primarily assigns unique pages or items that are described and matched with keywords and user-specified descriptions. Indexing and processing such large amounts of information is humanly impossible, but search engines are able to handle such tasks especially if keywords are programmed to identify them and properly classify the pages, leading to higher search engine page rankings.


This is the step where the engine compares the indexed page in the database with the search string to pull out the information that the user needs.

Calculating Relevancy

That’s the next move. The importance of indexed content to keyword searching is focused on various algorithms having relative weights that are various for factors such as keyword density, links, and metatags, etc. This is why different search engines are producing different search results for the same search string. All search engines regularly change algorithms; hence it is important that web pages adjust to these changes by devoting time and effort to SEO so that websites are consistently ranked.


This is nothing more than a view of the collected results in the web browser of the user; the list can be very long, but the most important websites are ranked at the top, followed by websites that are less and less important.

Rules & Guidelines Of Search Engines

Every search engine out there has certain rules that any website needs to follow. As you know, there are many things out there on the internet that are illegal, etc, so a search engine should not make them easily available. Many may use other spamming tactics to try to manipulate the search engine because it is not reasonable to provide may with the website over others. Reading into the rules of any search engines you choose to rate a website on is worthwhile because you have a better understanding of what they’re looking for.

How do search engines work? Nobody knows exactly how the algorithm works or something like that, but you do see people googling how the search engines work? People see the triple-phase cycle being used. There are plenty of different search engines out there, with the biggest one is Google.

Actually if you look at this, the crawl and index and the algorithm should tell you how it all works. What I want to do is think about some of those stuff, and how it works. First and foremost, your website needs to be designed correctly. You’ve got to have a website Google can crawl, search, and the bot will go in and out and check what you’re doing, crawling and indexing sites. And if you like if you’re asking the question of how Google works, you have bots or a Google app. Several search engines, and also tools for search engine optimization such as SEMrush or Ahrefs.

Essentially, that’s what Google is doing, the bot is searching for websites. Web crawling is the first step. And that’s one thing when you hear people thinking about the bot, spider or something, crawler, it’s the same thing. What we found is a web app called Google. First and foremost, it’s smart to mount Google’s search console solely no, not only because it does a ton of different stuff. So you know, if you want to see how Google crawls your website, if it is indexing, if there are any issues, then you can get all the information from the search engine.

Google needs to browse, and all the sites on the website are indexed. Now, one of the big items here is walking. It is a critical part of getting Google to crawl your website. Another is to have the context indexed. People who copy and paste material are a very common concern. Today, whether you copy and paste material from another webpage, or the list of a retailer, or whatever it might be, and put it on your own webpage, the odds of indexing the page are slim based on how much of it you copied.

Then you will go through the search console, to see how many pages are indexed. We will see how many sections are omitted, as well. You remember, and the other items you would like to remove from Google’s database inside a page, such as search images and many other items. So you want to make sure for eCommerce platforms where certain pages are not indexed or items that could have the definition, you know, different package sizes.

So for example, for this black shoes, you might want to crawl and index the black shoe tab, but you know, you might … if the contents are going to be the same on various other aspects of that shoe, other variants of the items, then you’re going to be penalized for duplicate content so you do not want to index all sorts of product variations. So if it’s black leather, and they come in six, seven, eight, nine, ten sizes, then you do not like six, seven, eight, nine, ten indexed socks. You know, it is more than enough to get one of those sites indexed.

The search console lets you see what’s indexed and see if there are any problems. But in terms of redundant content, there’s a device out there called and by putting in your domain name, you can conveniently run your website over here. What will happen is to mention your domain name, and what Copyscape would do is show you certain sites on the website that have similar content. And you will see here, everybody is taking material for this 100 Days of from Amazon’s website. If you want to rate high, this is what you can not do.

Google is smart, it will sort out redundant material, and if you want to use the words of a layman, it will dump it in the bin. And the search engines operate this way. They crawl, then index, the algorithm will naturally be put into action and whatever else they’re searching for. So if you get crawled so indexed in the first place, you have a chance to rate. If this is on page one or page ten, you have a chance to rate high. Yet they are also going to remember other issues. You’re very unlikely to score high on advertising alone because it’s a very, very niche market that you’re operating in or a non-competitive geographical region.

And this is how layman search engines operate. Clearly the mechanics behind Google servers and everything else that goes in, you know, it’s much more complicated. If you want to understand how all this works I’m sure there are central, experienced people you can talk to like Don Anderson and numerous other tech SEOs who are absolutely obsessed about how these search engines work and are doing a lot of research on all that kind of stuff trying to get to the bottom of it. And they are super smart people and these guys are technical things. But this is how the search engines work in terms of the layman.

So the main part is the crawling, the indexing and then getting the website ranked. But the search console on Google is something you want to build from the get-go. You can provide an overview, a rating, of your website. This also offers you a whole host of other things there, such as getting administrative action taken against you. Desktop accessibility, if you have maps of the app, and even many other stuff. And you can see my site map here, all of that sort of stuff when Google last read it.

Here’s a whole host of other stuff you should look at, and what will help you to get a lot more value from your website. And naturally, it can also bring up some errors and stuff, so you just want to be sure that your website is error-free, so be sure you look at it, because like I said, that’s pretty much how layman’s search engines function.
