large websites efficiently, while allowing you to analyse the results in real-time. It gathers
key onsite data to allow SEOs to make informed decisions.

Analyse Page Titles & Meta Data
Analyse page titles and meta descriptions during a crawl and
identify those that are too long, short, missing, or duplicated
across your site.
Discover Duplicate Content
Discover exact duplicate URLs with an md5 algorithmic check,
partially duplicated elements such as page titles, descriptions or
headings and find low content pages.

headings, prices, SKUs or more!

Out of the myriad of tools we use at iPullRank I can
definitively say that I only use the Screaming Frog SEO

rapidly improving and I regularly find a new use case. I
can't endorse it strongly enough.

initial SEO audits and quick validations: powerful,

I’ve tested nearly every SEO tool that has hit the market,
but I can’t think of any I use more often than Screaming
Frog. To me, it’s the Swiss Army Knife of SEO Tools. From
uncovering serious technical SEO problems to crawling
top landing pages after a migration to uncovering
JavaScript rendering problems to troubleshooting
international SEO issues, Screaming Frog has become an
invaluable resource in my SEO arsenal. I highly
recommend Screaming Frog for any person involved in
SEO.
Glenn Gabe
Founder, GSQI
Screaming Frog Web Crawler is one of the essential
tools I turn to when performing a site audit. It saves time
when I want to analyze the structure of a site, or put
together a content inventory for a site, where I can
capture how effective a site might be towards meeting
the informational or situation needs of the audience of
that site. I usually buy a new edition of Screaming Frog
on my birthday every year, and it is one of the best
birthday presents I could get myself.

About The Tool
The Screaming Frog SEO Spider is a fast and advanced SEO site audit tool. It can
be used to crawl both small and large websites, where manually checking every
page would be extremely labour intensive, and where you can easily miss a
redirect, missing page title, or duplicate page issue. You can view, analyse and
filter the crawl data as it’s gathered and updated in real-time in the apps UI.
The SEO Spider allows you to export key onsite SEO elements (URL, page title,
meta description, headings etc) to a spread sheet, so it can easily be used as a
base for SEO recommendations. Check our out demo video above.
Crawl 500 URLs For Free
The ‘lite’ version of the tool is free to download and use. However, this version is
restricted to crawling up to 500 URLs in a single crawl and it does not give you full
access to the configuration, saving of crawls, or advanced features such as
JavaScript rendering, custom extraction, Google Analytics integration and much
more. You can crawl 500 URLs from the same website, or as many websites as
you like, as many times as you like, though!
For just £199 per year you can purchase a licence, which removes the 500 URL
crawl limit, allows you to save crawls, and opens up the spider’s configuration
options and advanced features.
Alternatively hit the ‘buy a licence’ button in the SEO Spider to buy a licence after
downloading and trialing the software.
FAQ & User Guide
The SEO Spider crawls sites like Googlebot discovering hyperlinks in the HTML
using a breadth-first algorithm. It uses a configurable hybrid storage engine, able
to save data in RAM and disk to crawl large websites. By default it will only crawl
the raw HTML of a website, but it can also render web pages using headless
Chromium to discover content and links.
