Can I compare any two sites?

Yes. Both are fetched from outside the network, so it works on any public site, not just stores.

Does it show competitor keywords or backlinks?

No. Those need a licensed data set we do not have, so we do not invent them. It compares the technical and content signals each site actually serves.

Is it fair on large sites?

Both are sampled the same way (a bounded number of pages), so neither is favoured by size. It is a like-for-like sample, not a full crawl of either.

How does your site compare?

Paste your site and a competitor's. Both are crawled from outside the network with the same checks, then shown side by side — so you can see what they do better and what you already do well.

A bounded sample of each site, the same way for both. Nothing is stored.

What this compares

The same checks on both URLs — reachability, indexation, markup, links, delivery and, for stores, catalogue — then a per-check difference. It does not invent competitor keywords or backlinks; those need a licensed data set, so it compares the signals each site actually serves.
