I've been working as an SEO for over 15 years. I was there when link farms worked and when optimized meta titles H tags were enough on-page optimization to get you ranking.

I don't like tools like Labrika, so I don't but them. I don't need automated analysis because they never provide information I can not quickly find with a more advanced tool and they also report a lot of false positives. I run Screaming Frog with custom search and extractions to perform a real, professional analysis. There's nothing like Screaming Frog, and Labrika is not a replacement for forensic SEO tools. BUT: it's really, really good. I'm impressed:

1. I have no doubt that behind this tool there's a team that has a lot of SEO experience. Multiple redirects, short descriptions and issues with titles are common, but most automated analysis tools don't have them. Labrika does.
2. So, so many perfectly organized categories: Pages blocked from indexing, duplicate content, external links... I mean, I have SEO-nerdy fun just browsing the reports.
3. You can connect it with your GA and GSC to get very useful insights, like bounce rate by traffic sources or pages without traffic.

I know I shouldn't be embarrassed, but I found myself using the tool. A lot:
1. I run quick analysis on websites I don't need to perform an in-deep one, so I can efficiently report some issues to a prospect.
2. When I perform a deep analysis with Screaming Frog, I still add it to Labrika to be sure I don't miss anything.

This is a great deal. I'm amazed by the quality of the product and very happy I grabbed the LTD. They have everything to become a successful company, because it's obvious they have SEO experience.
