Both are free, both require no signup, and both scan a live page directly. The difference is depth and what happens after the scan.
What BlueGrid Media actually checks
43 automated signals from a single fetch of robots.txt, llms.txt, sitemap.xml, and the live rendered page, plus a separate 11 signal manual methodology built specifically for contractors and home service businesses. This is currently the deepest free technical scan available in this category, and it is genuinely useful for a site owner who wants the most granular possible read on crawl access and structured data before doing anything else.
What ours actually checks
8 signals, robots.txt access, an llms.txt file, schema markup, rendered content depth, meta structure, content quality, heading structure, and FAQ detection. Fewer checks, same core categories, faster to read.
The real difference is not signal count
BlueGrid Media hands back a number and a breakdown. Ours does too, but it sits inside a managed AEO service, so the team that ran the scan is the same team that fixes what it finds. If the goal is the deepest possible free technical audit to run yourself, BlueGrid Media is the better tool for that specific job. If the goal is to find the gaps and then have someone actually close them, that is what ours is built for.
Neither tool, ours included, can see a model's private ranking logic or promise a citation. Both are diagnostic starting points, not guarantees.
