Site Comparison

You versus your competitor, eight measured criteria

Comparing two sites on measured criteria ends opinion debates. This tool analyses both sites live, criterion by criterion, and turns the gaps into an action plan.

Free, no account, no daily limit

Free tool, no signup and no daily limit, published by LANXAS, a French artificial intelligence company. Servers are located in France and no analysis data is retained.

The eight criteria compared

Overall homepage SEO score, computed with identical rules for both sites.
Volume of content actually present, in words.
Internal linking density, which distributes authority between pages.
Images without alternative text, an indicator of care taken over the site.
Presence of structured data.
Presence of an llms.txt file.
Server response time, measured at test time.
Domain age, from public archives.

How to use it

Do not try to win on all eight. Focus on the ones where the competitor leads: those are your only real priorities, and the tool isolates them for you.

Some gaps cannot be closed and should not worry you. Domain age in particular cannot be fixed: it is offset by publishing quality and frequency.

Frequently asked questions

Can I compare any site?

Yes, as long as it is public and reachable. The tool visits both sites the way any visitor would, without intrusion.

Why does the comparison take time?

It chains two full audits and two archive lookups. Expect thirty to sixty seconds depending on both sites speed.

Does it measure backlinks?

No, that data comes from paid databases. We would rather not display a number we cannot measure. Domain popularity offers an independent, verifiable approach.

Can I compare more than two sites?

Use the batch audit, which analyses up to fifteen sites and ranks them by opportunity.
