Recognizing access blocks

CAPTCHA / reCAPTCHA: "I'm not a robot" checkbox or image grid challenge
Cloudflare: "Verify you are human" page with spinner, then checkbox
HTTP 403 / Access Denied: blank page with "Access Denied" and reference number
Rate limiting: repeated failures on the same site after several requests

Immediate workarounds

Google search blocked → switch to Bing, DuckDuckGo, or direct URL navigation
Site returns 403 → try Google cache: search cache:<url> in Google, or use Wayback Machine (web.archive.org/web/<url>)
Cloudflare challenge → try archived version, or extract info from search snippet instead of visiting the page
Shopping site blocked (Macy's, NBA Store) → use search engine product listings or try mobile URL variant (m.<domain>)

Prevention tactics

Avoid rapid sequential searches — add 2-3s pauses between Google searches
Open links in the same tab instead of spawning multiple tabs
Use direct URL navigation when you know the target URL (type in address bar)
For multi-step searches, vary search terms slightly to reduce pattern detection

When access is fully blocked

If the primary site is inaccessible after 2 attempts, pivot to alternative sources immediately
Do not retry the same blocked URL more than twice
If the task requires specific site content and all access is blocked, submit your best answer from available information rather than looping
