Spider Web

What is a Web Spider?

A Web Spider or web indexer is a bot that is responsible for collecting data and creating a record of it. They are used in various fields and for very varied tasks, but the most common use that is generally given to it is to enter a series of URLs that are in a list known as “seeds”.

The bot enters these pages one by one and keeps a record of each one so that they can be visited later.

The pages collected by the web spider are saved as you would see them when you normally browse them, but they are stored as a “snapshot”, as screenshots so that browsing can be faster. However, although they are incredibly efficient, they need human help to be able to deliver accurate results, as there are many things that can hinder the judgment of these bots.

Sometimes, URLs that appear to be duplicates are actually different formats of the same site presented as individual links. So, if a web spider detects a duplicate, it doesn't always mean that it is. That's why there needs to be someone monitoring the results of these little cyber helpers.

What is a Spider Web for?

This tool can be used by a webmaster to detect possible broken links and other problems within a website. They are also very efficient for, for example, registering the catalog of an online sales page and collecting price and product data to create comparisons and other useful records.

However, the most common use is to help search engines find new pages and register them in an index that allows faster searching. The Web Spider is what allows Google to register each new site that is uploaded to the network and assign it a place in its results according to its pagerank algorithm.

The quintessential example of this technology is the one used by Google to position websites in its results. Thanks to this simple but efficient bot, the search giant can register each new site, evaluate its value and assign it an appropriate place in the search results.

It works sequentially. As mentioned before, the spider visits all the sites provided by a list and they are saved in a register to then be subjected to Google's pagerank algorithm and thus be positioned appropriately.
