What is crawling in SEO Services?
Search Engine Crawling is a method used by Search Engines to kind of survey websites to identify those that should be ranked among the top searches based on the query. The crawlers download your page, extracts all the links related to your website to survey all the pages, and conducts their study.
This is the fundamental step that determines search engine optimization results. This process happens quite often to check for updates among websites to identify changes that are worthy of a push to the upper ranks of the SEO. If there are changes they are refurbished in the index of the website to keep a record of the changes.
How does crawler work for Search Engine Optimization?
Each Search engine has its own crawlers to carry out this task for it and its own search engine optimization regulations. The process is quite straightforward, the crawlers start off by downloading the robots.txt file of each website. This file contains important rules and regulations about the crawling privileges. It lists the URLs that should be crawled together with information on sitemaps as well.
The Search Engine has a unique algorithm that determines how the crawlers go about accessing the information on the webpages and also on how often a page should be rechecked. The algorithms identify the frequency of rechecks based on the frequency of changes it observes while crawling.
How to identify these web crawlers?
Whenever crawlers or bots of an SEO services company inspect web pages, they pass a user agent string to your designated web server to be able to access your files. It is very much like asking your permission to see your robots.txt file and visiting the URLs. Hence, this gives a clear indication of when your website has been crawled.
For example, there are several user-agent strings that Google uses:
Googlebot/2.1 (+http://www.googlebot.com/bot.html)
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
Googlebot/2.1 (+http://www.google.com/bot.html)
Though these requests can come from almost anyone, the IP address would help confirm which search engine had crawled your website. This can be done using a process known as reverse DNS lookup. This tool gives you the domain name associated with the IP address you decide to check it for which lets you determine which SEO Services is conducting an inspection.
