If you're heavily involved in SEO-related work, it's almost certain that you know what a web crawler or a web spider is.

For those of you who don't, a web crawler is a tool that can have a great number of uses like making copies of all visited websites for later implementation by various search engines, or  automating various maintenance tasks (checking link validity or HTML code structure, for example), but they're also particularly useful when it comes to gathering information.

Hextrakt Crawler is a professional, comprehensive yet surprisingly user-friendly tool that, thanks to its adaptive asynchronous technologies, is perfectly suited for spidering bulky websites and there's really no way around it: it's one of the best tools of its kind.

Another noteworthy aspect of this app is the fact that it features Google Analytics and Search console integration. As expected from a full-featured web spider, it also provides you with dozens of ways to categorize your URLs in order to improve the quality of your websites, as well as to create custom filters and requests to make sure that your data is as relevant as possible.

But, truth be told, it's only when you get to the data visualization part, that you can really appreciate this app's worth. The crawl feedback that this utility provides you with is simply mighty, with an impressive amount of both SEO and KPI-relevant details, and beautiful charts, graphs, and other types of data visualization representations.

The neat thing here is the fact that all these eye-catching data visualization data can also be exported to CSV and HTML formats. In addition to everything, you are also provided with the option to compare various crawls, which is great for monitoring your website's SEO across different periods of time.

To conclude, as far as web crawlers go, Hextrakt Crawler is definitely one of the best representation of what a tool of this sort should feel and look like. It has all the required underpinnings and technologies of a professional web crawler while managing a level of user-accessibility worthy of far more simplistic app.
