Two public profiles · no score or winner
overdrive.com and zepto.com
Measured takeaway
overdrive.com blocks model-training crawlers; zepto.com has mixed rules for model-training crawlers.
Measured in Botfy's 2026-09-07 publication.At a glance
A difference appears only when both sites have comparable evidence. Unavailable or unresolved observations remain incomplete.
| Evidence | overdrive.com | zepto.com |
|---|---|---|
| robots.txt | Served and parsed | Served and parsed |
| Google crawl posture | Open | Open |
| Unnamed crawler fallback | Partly Restricted they inherit the wildcard (*) group's rules | Partly Restricted they inherit the wildcard (*) group's rules |
| Base /llms.txt | Not found when probed | Not probed |
Treatment by purpose
Only resolved blocked, allowed, or mixed states count as a policy agreement or difference. Unnamed agents still inherit each site's wildcard rules.
| Declared purpose | overdrive.com | zepto.com |
|---|---|---|
| Model training | Blocked | Mixed |
| AI search | Not explicitly addressed | Mixed |
| Live assistant fetch | Not explicitly addressed | Mixed |
| Opt-out directives | Not explicitly addressed | Allowed |
| Ambiguous / undocumented | Not explicitly addressed | Blocked |
Named agents
Measured differences appear first. “Not explicitly addressed” is not the same as allowed; the site's wildcard fallback governs that crawler.

How each site compares with its own rank peers
The sites may belong to different rank bands. Each percentage keeps its own population and denominator; Botfy does not subtract rates from unlike cohorts.

How this comparison is measured
Both sites use Botfy's latest published observations. A missing fetch, unresolved agent verdict, and measured absence are different states. Peer percentages use each site's exclusive Tranco rank band and print their own denominator. Populations, sources, and limits →
