I have been using Lumar for the past 3 years as a very effective tool to keep track and optimize several websites in the company.
We use Lumar with crawls on a weekly basis that we later use to implement changes. I love the fact that I can add people to be notified for each of the projects we crawl so they can perform the needed tasks. Also as our websites are quite similar, having a comparable SEO score allows us to match the progress done in different projects.
I like that hints are provided everywhere by hovering on certain labels so it is easy to learn what certain metric is about.
A very interesting feature is the Traffic Funnel which quickly helps notice where problems might lie. Review collected by and hosted on G2.com.
Sometimes identifying where an error is coming from (eg: 404s can be from pages in sitemap, crawl, google, etc) Review collected by and hosted on G2.com.
