There is currently no tool that really does a GEO audit (afaik). I feel like I really have something a bit special that fills a need.
It's not "everything", but it's an huge timesaver for a good 20+ factors and it will always be free to scan a single page. For someone who doesn't know how to or doesn't want to look at code or crawl, it can really save time.
For quality control purposes there is a 24 hour turnaround on processing, so thank you for your patience and trust.
For reference, I'm an unemployed in SEO, marketing, and content. I thought of the idea from trying to do my own site audits to learn.
