Crawling – what is it and how does it work?

Crawling is the process of integrating new websites into the Google search engine. During this process, everything is determined by the used meta tag:

  • indeks
  • no-indeks

In the first case, Google robot (also called a spiderbot, a web crawler or web wanderer) will visit your website, examine the source code and then index it. On the other hand, the no-index meta tag means that the page won’t be included in the web search index. So when you browse the net, you actually browse the Index, the Google database.

Google Bots check many factors on the website before indexing it – they take into account such elements as keywords, content, correct source code or title and alt attributes.

How to check if your website is indexed?

To check the indexing status of a specific link, such as a profile, just enter it into the search engine. If it appears in the search results, it means that your website has been indexed. If you wish to check the indexing of a whole website or blog and the number of new topics and indexed subpages, just type in:

„site:http://websitename.com”

Crawl Budget

Crawl Budget is a budget for indexing your website. More specifically, Crawl Budget is the number of pages indexed by Google robots during a single visit on your site. The budget depends on the size of your website, its condition, errors encountered by Google and, of course, the number of backlinks to your site. Robots index billions of subpages every day, so every visit to the site burdens some of the owner’s and Google’s servers.

There are two parameters that have the most noticeable impact on Crawl Budget:

  • Crawl Rate Limit – limit of the indexing factor
  • Crawl Demand – frequency with which the website is indexed

Crawl Rate Limit is a limit that has been set so that Google doesn’t crawl too many pages in a given time. It should prevent the website from being overloaded as it refrains Google from sending too many requests that would slow down the speed and the loading time of your site. However, Crawl Rate Limit may also depend on the speed of the website itself – if it’s too slow then the speed of the whole process is also slowed down. In such a situation Google will be able to examine only a few of your subpages. Crawl Rate Limit is also influenced by the limit set in Google Search Console. The website owner can change the limit value through the panel.

Crawl Demand is about technical limitations. If the website is valuable for its potential users, Google robots will be more willing to visit it. There is also a possibility that your website will not be indexed even if Crawl Rate Limit isn’t surpassed. This may happen due to two factors:

  • popularity – websites that are very popular with users are also more frequently visited by Google robots.
  • up-to-date topicality – Google algorithms check how often the website is updated.

To conclude

There are numerous ways to crawl your website in Google. The most popular ones include:

  • website indexing with the use of Google Search Console,
  • XML maps,
  • website indexing PDF files,
  • website indexing with the use of online tools.

While indexing your site, you need to take into account several factors that will make it easier for you to achieve the best possible results. These factors include:

  • meta tags,
  • the robots.txt file,
  • Crawl Budget.
