warning robots.txt-disallowed URL receives internal links (crawl-budget leak)
Rule budget.disallow_linked · Budget · 1 occurrence(s)
- https://praesora.com/payment.html?sku=MANDATE_USD_75000 — internal links point to https://praesora.com/payment.html?sku=MANDATE_USD_75000, which robots.txt disallows for Googlebot — Googlebot discovers the URL, checks robots, then rejects it without indexing, wasting crawl budget and losing the link equity.
