First, be on time.

In the first chapter Search engines are answering machines. They are designed to find how to comprehend, organize, and understand the web’s content to give the most relevant outcomes to the questions that people are searching for.

To show up in the results of a search, your site must be first visible in search results. This is perhaps the most crucial component in the SEO puzzle If your website can’t be discovered and isn’t visible to search engines, it’s unlikely that you’ll be able to appear in SERPs (Search Engine Results Page).

What is the function of search engines?

Search engines perform three fundamental purposes:

  1. Crawling Explore on the Internet looking for relevant content and examining the content and code for every URL they come across.
  2. indexingStore and arrange the contents discovered in the process of crawling. When a page is added to an index, that page is running process to display it in response to relevant queries.
  3. Rating:Provide the pieces of content that are most likely to answer an individual’s search query. This means that the results are sorted according to the most pertinent to the least relevant.

What exactly is crawling a search engine?

Crawling is the process of discovering where search engines send out teams consisting of robotics (known as spiders or crawlers) to search for fresh and up-to-date content. The type of content is different and could include an image, a web page video, PDF or PDF, etc. Regardless what format it is, it is discovered through hyperlinks.

What’s the meaning of that word?

Googlebot begins by retrieving several web pages then it follows the links of those pages to discover new URLs. As it travels along this set of links, the crawler will be in a position to discover new content to add to their index known as Caffeine which is which is a huge database of recently discovered URLs that can later be found whenever a user is searching for information about a website that the content of the URL is a suitable match.

What exactly is a Search Engine index?

Search engines store and process the information they discover through an index. This is a vast collection of all the information they’ve found and believe to be adequate enough to offer to people searching.

Ranking of search engines

The order in which search results are arranged according to relevance is called ranking. In general, it is possible to think that the more the website’s ranking and the more relevant it believes that the website is to the search query.

It’s possible to stop crawlers by search engines from certain areas or the entire site or tell search engines not to store specific websites in the index. There are many reasons to do this, if you wish to have your site to be found by search engines then you must first ensure it’s available to crawlers and indexable. If not, it’s as being invisible.

When you’re done with this chapter you’ll know the background you’ll need to utilize the search engine instead of working in opposition to it!

Crawling Does search engines locate your websites?

You’ve probably learned that making sure that your website is indexes and crawled is an essential step for appearing in SERPs. If your site is already on the index site then it could be beneficial to start by checking how many of your sites are listed in the index. This will provide you with some valuable information about the extent to which Google has been crawling your site and locating every page you’d like you to see, as well as not finding any that you do not.

One way to check your indexed pages is “”, an advanced search operator. Head to Google and type “” into the search bar. The results will be returned Google have in its database for the website specifically:

The amount of results Google provides (see “About XX results” above) isn’t exactly exact, however, it gives an understanding of which pages are being indexed on your website and the way they’re currently being displayed on search result pages.

To get more precise results, keep track of and make use of for more accurate results, monitor and use the Index Coverage report in Google Search Console. You can enroll for a no-cost Google Search Console account even if you do not have one. This tool can create sitemaps for your website and track the number of pages submitted to Google and how many are actually added to Google’s index among other things.

If you’re not appearing in search results There are a couple of possible reasons:

  • The site you’re on is fresh and hasn’t even been crawled as of yet.
  • The site you’re visiting is not connected to any other websites.
  • The navigation of your site makes it difficult for robots to crawl your site effectively.
  • Your website contains a basic code called crawler directives which block the search engines.
  • Your website was disqualified by Google for using spammy tactics.

Let search engines know how they can crawl your site

If you’ve used Google Search Console or the “” advanced search operator and discovered that your most important websites aren’t in the index, or that some of your less important pages were incorrectly indexed, there are certain optimizations you can make to help guide Googlebot the way you would like your web pages to be to be crawled. Informing search engines of the best way to crawl your website can provide you with more control over what is put into the index.

Many people focus on the importance of making sure Google will find their most important pages, but it’s very easy to overlook the likely to be some pages you do not wish Googlebot to discover. This could include old URLs with very little content multiple URLs (such as the sort-and-filter parameters used in E-commerce) or promotional codes as well as test or staging pages, and more.

To steer Googlebot away from specific sections and pages of your site, you can use robots.txt.


Robots.txt files can be found within the directory root of web pages (ex. and suggest which parts of your site search engines should and shouldn’t crawl, as well as the speed at which they crawl your site, via specific robots.txt directives.

How Googlebot responds to robots.txt files

Some web robots don’t follow robots.txt. Some people with malicious intentions (e.g. E-mail address scrapers) develop bots that do not adhere to this standard. In reality, some malicious hackers use robots.txt files to discover the exact location of your private data. While it may seem sensible to stop crawlers from private pages like admin and login pages to ensure that they do not appear on the search results, including the URLs’ location in a widely accessible robots.txt file means that malicious actors are more likely to find them. It is better to block these pages and hide these pages behind a log-in page rather than putting them into the robots.txt file.

Sometimes, search engines will be able to locate certain parts of your site through crawling, however different pages or sections may be hidden due to reasons of one kind or another.

Consider this: Will the bot be crawling across your site but not only to it?

Do you have your information being hidden by login form fields?

If you require your users to sign up to fill out forms, or complete surveys prior to accessing specific information, search engines won’t be able to access those protected sites. A crawler isn’t likely to sign in.

Are you relying on Google search forms?

The search form cannot be used by robots. Certain people are of the opinion that when they add the search box on their website that search engines will be capable of finding everything users are searching for.

Are there hidden textual content?

It is always best to include text in the markup of your site.

Do search engines understand the navigation of your website?

As a crawler has to locate your site through links from other websites and require a set of links within your own website to direct it from page to. If you have a page that you’d like search engines to locate, but it’s not connected to any other page that’s almost inaccessible. A lot of websites make the error of arranging their navigation in ways that make them unaccessible by search engines. This can result in which hinders their ability to appear within search results.

Common mistakes with navigation that prevent crawlers from seeing the entirety of your website:

  • Mobile navigation gives different results than your desktop navigation
  • Any kind of navigation in which the menu items aren’t within the HTML such as JavaScript-enabled navigations. Google has become more proficient in crawling and comprehending Javascript however, it’s not yet a complete method. The most reliable method to make sure that something is discovered, understood, and then indexed by Google is to put it in HTML.
  • Individualization, or showing distinct the navigation of a certain kind of user versus other visitors might seem like cloaking the crawler of a search engine.
  • Not linking to the primary page of your site through navigation menu — remember that links are the pathways crawlers use to navigate to get to new pages!
