GoogleBot SEO Activity Principle to Know
GoogleBot SEO Activity Principle to Know

What is Googlebot?

Googgle bot is a crawler used by Google to crawl websites. It is Google's access to the website data by the mechanism through the link.
Googlebot 's information is collected and used to update the index of the website.
Googlebot accesses billions of websites and is constantly on the move to crawl sites.
Website crawlers, also known as bot, robo-bots or spiders, is a program that collects information and sends it to a place to store data.
Google bot retrieves data in binary form (100010001010,0101010001111 ...) when it crawls, Google sends it to Google's index, where Google conducts comparisons and ratings, so Google High ranking first thing is that the website must be easily structured for bot crawling, easy access information.
You must constantly ask questions for your website
Does Google bot easily "see" the information on my website? 
Can Google bot retrieve all information and links in the web? 
Can Google access all website resources? 
In addition to the optimization techniques in SEO, the way to make google quickly understand the content of the website is quite important, you imagine a site with a slow load, Google Bot can not access the data. , repeatedly returns data on 404 results, can not scan the data, no rank is a natural thing.

How does Google Bot work?

Google bots use sitemaps through sitemaps and links are found crawling ahead, If the Google bot finds changes to the links and broken links it will record and update the index. 
To ensure that Google Bot crawls the correct indexes you need to check the indexes through the site: domain.com structure .
By setting "site:" in front of your domain, you'll ask Google to list the pages that Google has indexed for your site.
Note there is no white space between "site:" and domain

How does Googlebot view your webiste?

Googlebot does not see complete webpages, it only sees the individual components of that page.
If any of these components are not accessible to Googlebot, it will not send them to the Google index.
To use my previous example, this is Googlebot viewing site (html and css) but no image.
Google needs a complete picture to rank websites, not just the details.
There are many cases where Googlebot can not crawl a website:
Site resources are blocked by robots.txt file
HTML error or invalid encoding
Dynamic linking is too complex
It depends on the flash and the technology that led to the website crash.
If the CSS and javascript files are blocked by a robots.txt file, they can be misleading. 
An example to illustrate this would be a mobile site that uses CSS or javascript to determine what to display depending on what device is viewing the page. If Googlebot can not access the CSS or Javascript of that page, it may not recognize the page as portable.
Google will "read" but different from what HTML is presenting.
For a more secure look you can go to Search Console to collect data that will see the website
