MetricSpot audit traffic

MetricSpot runs SEO and AI-readability audits on URLs that users explicitly submit. If your firewall is blocking us, here's how to let us through.

Audit traffic comes from this IP

178.105.101.224

Audit traffic uses a standard Chrome user-agent

Mozilla/5.0 (Macintosh; Intel Mac OS X 14_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36

Why we use a standard user-agent

WordPress security plugins (Wordfence, Shield Security NotBot) and Cloudflare Bot Fight Mode pattern-match the word "bot" in user-agents and force a JavaScript interstitial we can't solve in 15 seconds. Audit traffic uses the same UA as a regular Chrome user, so identification for allowlisting happens by IP - 178.105.101.224, a single static IP - rather than by UA.

How to allowlist 178.105.101.224

Cloudflare
Cloudflare → your site → Security → WAF → Tools → IP Access Rules. Action: Allow. Value: 178.105.101.224. Zone: This website.
Wordfence (WordPress)
Wordfence → Firewall → Tools → Allowlisted IP Addresses. Paste 178.105.101.224 and save.
Sucuri
Sucuri Firewall → Settings → Access Control → Whitelist IP Addresses. Add 178.105.101.224.
AWS WAF
AWS WAF → if your site is behind CloudFront, switch the region selector to Global (CloudFront) first (a regional Web ACL can't attach to a CloudFront distribution) → Web ACLs → your ACL → Rules → Add rule → IP set match. Create an IP set with 178.105.101.224/32 and an Allow rule that runs before your blocking rules.
nginx
Allow the IP before any deny rule:
# In your server { ... } block, before any deny rules
allow 178.105.101.224;
deny all;
Apache
Apache 2.4+ uses Require ip:
# In .htaccess or vhost config
<RequireAll>
  Require ip 178.105.101.224
</RequireAll>

FAQ

Why does my audit fail with "firewall blocked"?
Your site returned an HTTP 4xx or 5xx response before we could analyse the HTML. The most common cause is a WAF rule blocking new IPs. Allowlist 178.105.101.224 and re-run the audit.
Do I need to allowlist the user-agent too?
No - we use a regular Chrome user-agent. Allowlisting by IP is enough.
What does MetricSpot do with my site's content?
We fetch the HTML of the URL you submit, run our 91 audit rules locally on our server, and store the score + findings in your account. We don't redistribute your content and don't follow links to other pages on the same site.
Can I block MetricSpot?
Yes - deny 178.105.101.224 at your firewall. Audits for your URLs will fail with an unreachable error, which the requesting user will see.
