If you notice your site is taking a long time to load, then you should first use PageSpeed Insights to see what can quickly be optimized (also check your file sizes, hosting server, NGINX and other common sources of slow speed, too.) And, if you've notice gradually fewer Organic Search visits, PageSpeed Insights might be able to help. As Google is reducing the prevalence of slow sites, you could be losing traffic. Speed up your page load times by finding what is blocking renders, slowing down contentful paints, and other critical page speed signals.
Screaming Frog SEO Spider is well suited to auditing brand new websites, when you need a quick, holistic view of the websites technical issues. Its great for providing a top line view of a websites architecture, perhaps for a new business approach where you need to assess the scale of work to maintain a website. Its also a useful tool in situations where you might need to see whether a large scale change in the website has taken place, you can see word counts, pages and their https response codes. Screaming Frog may be less useful if you need an idea of the customer experience on a website, it doesn't really provide information that helps assess how fast a website loads, what issues might come up when trying to convert or faults with the payment process. Screaming Frog is largely a technical SEO focused tool, it also can't assess the quality of a websites, layout or the quality of the content used on the website. As mentioned, its niche, but very useful within that niche.
Requires Java. This isn't a huge deal as many computers already have it installed, but it's yet another 3rd party component.
The free version has a crawl limit of 500 pages per site. This is fine for smaller sites, but if you're running a big e-commerce site then you'll need to pay for Pro version.
The user interface isn't very pretty. This is an analytics tool so it doesn't really have to be, but it might be helpful for improving the overall user experience.
The tool has become integrated into our teams daily workings and I have yet to find a tool other than scremaing frog to replicate all of our use cases for it. It's a great tool and we're sticking with it
Easy for me to use because I have using the product for a long time and understand the ins and outs of it. If I was a newbie, I would be completely lost. It does take some prior knowledge to operate this software and understanding of what a crawl means
Screaming Frog is a relatively primitive system, and doesn't need to be supported by devs or other software. Screaming Frog does interface directly with some programs that are most needed (Google Analytics, Search Console, Page Speed Insights), so that's convenient. It isn't widely supported by other programs, but it also doesn't need to be.
I think GTmetrix has some feedback that PageSpeed doesn't provide, but Google's tool is easier overall and has a better user experience; also offers compressed images, CSS, and javascript files if that's the case. Also, Google has extensive documentation to help you better understand what can be done to improve your grade.
Screaming Frog SEO Spider is probably the best non-client facing SEO audit tool in terms of technical SEO. There are other tools on the market that do a more complete job of keyword tracking, competitive analysis, and backlink profiles...however, for analyzing the technical SEO health of any website, Screaming Frog is the best
