Search engines are effective answering machines. Whatever you ask, there is always an answer online. 

But how do you get those answers? What does a search engine do? How do the search engines give you thousands of answers to your queries— all in a blink of an eye?

One of the crucial elements that can help answer these questions is website crawlers. Website crawlers are search bots that crawl through websites and discover, organise, and show the best results.

How Do Search Engines Work?

Search engines exist to understand your texts and display the best answers to your problems from numerous web sources. 

 

The goal is to show you relevant results. But they come in two different ways— organic and paid. 

As for the names, organic search results crawl through numerous web pages and look for relevant information. And displays all of them based on ranking factors. 

Talking about ranking factors, SEO experts leverage on-page, off-page, and technical SEO optimisation methods to make your website known to the search engines. It is a long term process and usually takes up to 3-6 months to index and rank your website on Google’s top page. High-quality content and regular website maintenance play the most crucial role here. 

On the other hand, paid search engine ranking or PPC is paying Google to show your website top. So, whenever someone is searching with your targeted keywords, your website will get first-page visibility. It shows almost instant results and great for quick ROI.

However, technically, a search engine works in three primary ways:

Crawling

Crawling is a never-ending process unless your website has been de-indexed for some reason. Search crawlers comb through online sources and look for fresh and existing content. It goes through every URL and code to identify available content online. 

Let’s see what Google says about crawling

Indexing

Indexing is more like organising a library. You have thousands of books scattered. Indexing will categorise them and keep them in their respective section. This process begins with crawling as the crawlers identify the types and categorise them accordingly. The search spiders also determine which source to keep in the library and not. Without indexing, your web page won’t show up on search queries. 

To check if your site is indexed, type site:yourdomainname and hit it. You will see a result page like below.

Ranking

When you have a top-notch website and SEO-friendly content, ranking will be a matter of the moment. Search engines crawl and index good content and show them according to its relevance to the search queries or keywords. The better quality content you have, the quicker you will rank for.  

So, that’s how a search engine primarily functions. One thing is certain, though: it’s all about crawlers. To learn more about how does a crawler based search engine work, let’s see what a search engine crawler is. 

What is a search engine crawler?

Crawler based search engines use crawling methods to gather data online. The bot combs throughout the online data gallery and looks for indexable content. Google and Yahoo are two popular crawler based search engines. The crawlers take every URL into account, list down keywords, and add them to the database. 

The main aim of these robots is to discover ever-growing content libraries and identify worthy ones. However, by content, it’s not the written texts. Any image, PDF, video, and other media files with links are subjected to be crawled and indexed.

It may sound too simple. But as mentioned before, the backend is loaded with actions. While you enjoy consumable data just by a click, search crawlers are digging up millions of web pages to show you the most relevant information. 

So, search spiders are busy bees— no doubt. And maybe so, sometimes you will require more time than usual to get your website indexed.

Why Is My Page Not Indexing?

Unfortunately, your website may not get indexed as per your expectations. There might be many reasons. For instance—  

Robots.txt file: This is a great spot to start with your journey towards fixing indexing issues. Google bot primarily looks into the robots.txt file when trying to index. If you are asking the spider not to index your webpage, it will do so. 

Too many redirections: Using so many 301 redirects can discourage crawlers to leave your site as it is. Moreover, it is quite annoying and audiences will abandon your website instantly. 

Duplicate or think content: Great content is useful and reader-friendly. So, if you have the aforementioned issues fixed, most probably your webpage is not indexed due to poor content. Upgrade your website content quality to invite crawlers and get indexed fast. Avoid duplicate content issues to avoid penalties as well. 

Page not responding: Consider the functionality of your website. Make sure the URL is not showing a 404 error message. 

How To Optimise Websites For Easy Crawlability & Quick Ranking?

The better your website’s crawlability is, the better your chances for ranking is. After all, your understanding of how does a crawler based search engine work impacts your SEO success.

So, when you are optimising your website for Google top page ranking, make sure you are aware of the below issues—  

Website structure

 Without a good website structure, you are building a castle in the sky. Website development can be tricky. You have to make sure you are designing and developing a responsive website that has a great structure. If you are unsure how you can improve it, hire a reputed web design agency to build an easily crawlable website. Put an XML sitemap on the website so that the spiders can identify and index your web page URLs quicker. Specify your title tag and meta description so that search spiders know what you are talking about. 

Content

Content is the knight, if not the king. Great content serves greater purposes— keeping audiences engaged and ranking quicker. Relevant and useful content libraries with proper SEO optimisation invites search engine crawlers more effectively. As a result, the first Google search engine result page becomes your everyday phenomenon. Complex content demotivates the web crawlers from indexing your website. So, publish properly optimised SEO-friendly content to outrank your competitors. 

“When you are designing a website, make sure you are optimising for page speed, content readability, and keyword distribution. This sends strong signals to web crawlers and helps you rank faster on Google.”

Authority Links

The number of relevant links will help your website get rank faster. The more your website gets links from relevant sources, the more search crawlers will crawl your site. Evidently, every piece of information will be inspected by the web spiders, keeping it hot all the time. Besides, use internal links to your web pages to show relevance and build a virtual content category. 

Keyword Optimisation

Keywords are the most crucial points for a crawler based search engine like Google. With precise keywords, you are asking search bots to show your website to the relevant people. Besides, it helps you rank on top pages. Use any popular keyword research tool like ahrefs and select the most suitable ones. As keyword selection is a tricky process, let the professional SEO practitioner do it on your behalf. 

Page Content

Crawler based search engines cannot read content buried under Flash and Java plugins. So, to make your content indexable, avoid using those. Keep the important information open to all search crawlers. This way, your website is ready to get indexed and ranked on Google. 

Final Words

To understand the basic science of search engine optimisation, you have to learn how does a crawler based search engine work first. The more you gather knowledge on those crawlers, the better you can optimise your website for them. 

Crawlers or spiders depend on your content and website structure to index your site and give it a decent ranking. Even though crawlers are independent, your action determines how search engine optimisation works on your virtual spot. So, make sure your website is not blocking crawlers with a noindex robots.txt file, you are publishing great content, and your SEO strategies are not fishy in the eyes of a crawler based search engine.
