Screaming Frog SEO Spider – Audit Your Site for Free!

Are you looking for a free tool that can accurately analyse your website and detect its weak points?

Website auditing is something that every serious online business owner should perform.

Sometimes, we spend a lot of time writing quality content and looking for the right images, but having the correct title and metadata, checking for broken links or discovering duplicate content is just as important.

Screaming Frog SEO Spider is a powerful website crawler that offers both free and paid features, that can help you improve your website’s visibility to search engines.

Screaming Frog SEO Spider installation

Before you proceed with the installation of Screaming Frog SEO Spider website crawler, make sure that your machine has got at least 1gb of RAM.

Installation is pretty straight forward, in fact, upon clicking “Download”, the website should already detect what operating system you are using and show you the correct installer to download:

  • Ignoring “no index” URLs
  • Avoiding response timeout by increasing the waiting time, which is useful for slow websites

Please refer to SEO Spider Configuration Guide to see the complete list with instructions.

Auditing your website

Open Screaming Frog SEO Spider and enter the URL you wish to crawl in the top bar, next to the tool’s logo and click on “Start”:

Audit website seo spider

The audit might take a while, depending on the amount of URLs that are being crawled.

Remember that, as a free user, you will only be able to crawl up to 500 URLs at the time.

A report containing the crawled website’s data will be shown under the relevant tabs:

  • Internal: displays all data crawled from all other tabs except the external, hreflang and custom tabs

Conclusion: Is Screaming Frog SEO Spider worth it?

Screaming Frog SEO Spider helps you find issues on your website and gives you loads of data you can work on.

If you are just starting out, then the free version will already give you enough work to do.

However, I recommend you eventually upgrade to the paid version to unlock its full potentials.

  1. This a great and simple to follow guide on how to use screaming fox seo spider.

    You laid it all out clearly and showed series of examples that helped emphasize your various points. This guide will be very useful for me. I have heard about this free tool before but I haven’t tasted its benefit this much. 

    This is the most comprehensive review I have ever read on  screaming frog which is an eye opener for me.

    This is the type of information some so-called professional bloggers will love to hide from public knowledge. I’m so happy I found your blog

    • Thank you Ola 🙂

      f you get to try Screaming Frog SEO Spider, please do let me know what you think!


  2. The screaming frog SEO spider sounds like a very relevant tool to help bloggers access the quality of their webpage. I’m going to try the SEO spider because I believe it’s a product that can help the overall usability of my website. If I join the paid service, can I earn by referring others?  Expecting to hear your response soon.

    • Hi Louis,

      No, I am afraid they do not have an affiliate program at the moment.

      This is stated in their FAQ section.

      Many thanks,


  3. Thanks for writing this screaming frog seo spider.i find this article so full of informative on how to install and use it and so other things 

    I must say this is my first time of reading or hearing anything about screaming frog seo spider maybe is because I am a beginner and am just writing my first content for my first website.but either way I will like to make use of screaming flog seo spider in other for my work to be as professional as possible 

  4. This is a very good feature in every website and most importantly, it is easy to install. Great job by the developers but my question is ” Does the screaming frog bot help in checking for plagiarism on the website”? In my opinion, the bot should also be able to check for plagiarism. 

  5. This is a very great post and a wonderful writeup too. I have always wanted something like this, a way to detect faults in my websites, what I need to do and fix for them to get better. I guess Screaming Frog SEO Spider according to your review will really do justice to any loopholes found provided I go fully for the paid version. Thanks for sharing this. Very helpful. 

  6. This is a nice product every website owner need to integrate on their websites. It is good the company has the free and the paid version. I would have to try the free version. first, based on the results I got that would determine if I would have to switch to the paid version. What are the options for people outside London and England as regarding attending the one-day training? Is there an alternative to this? The training cost looks high for a few hours of training. 

    • Hi Tolu,

      It looks like for now, the workshop is only available in London.

      I personally don’t think it is necessary for you to attend the workshop. They have a support team, so you can easily contact them and ask about things you need clarifications on 🙂
