It reduces bandwidth by 83% and tokens by 86% based on 970+ production URLs.\n\nHow much bandwidth does it save?\n\n83% average savings – 103 KB → 17.7 KB per fetch, measured across 970+ URLs on 3 production sites.\n\nHow much does it reduce AI token costs?\n\n86% token reduction – 13,900 → 1,960 tokens average, reducing AI processing costs significantly.\n\nWhat is the skip rate?\n\n90%+ skip rate – When content is unchanged, conditional requests return 304 Not Modified with zero body, eliminating redundant transfers.\n\nFor Publishers\n\nWill this affect my SEO?\n\nNo. TCT preserves canonical URLs and only affects AI crawlers. Search engines continue to crawl regular HTML. Google and Bing rankings are unaffected.\n\nDoes it work with my WordPress theme?\n\nYes. Content hashes are template-invariant – same content produces the same hash regardless of theme, CSS, or JavaScript changes.\n\nWhat if I change themes?\n\nNo problem. The plugin extracts core content independent of templates. Content hashes remain stable across theme changes.\n\nIs it free?\n\nYes for website owners. The WordPress plugin is GPL v2+, the Cloudflare Worker is MIT licensed. No cost to implement on your own sites.\n\nHow do I validate my implementation?\n\nUse the validator at llmpages.org/validator – Target score is 10/10 for full compliance.\n\nFor AI Crawlers\n\nHow do I discover TCT endpoints?\n\nStart with the sitemap at /llm-sitemap.json or look for <link rel=\"alternate\" type=\"application/json\"> in HTML.\n\nWhat client libraries are available?\n\nPython library: pip install collab-tunnel – Handles sitemap discovery, ETag caching, and verification automatically.\n\nHow do I verify content authenticity?\n\nCompare the ETag (SHA-256 content hash) with your own hash of the normalized content. Mismatches indicate tampering.\n\nTechnical\n\nWhat is template-invariant fingerprinting?\n\nContent is normalized (HTML/CSS/JS stripped) before hashing. Same content = same hash, even if the template changes. This enables stable caching across redesigns.\n\nWhat is the 4-part protocol?\n\n\nBidirectional Discovery – C-URL ↔ M-URL handshake\n\nTemplate-Invariant Fingerprinting – SHA-256 content hashes\n\nConditional Request Discipline – 304 Not Modified responses\n\nSitemap-First Verification – Zero-fetch optimization\n\n\nWhat are the production deployment results?\n\n\nwellbeing-support.com – 400 URLs, 10/10 score, 83% bandwidth savings\n\nomacedonii.com – 500 URLs, 10/10 score, 83% bandwidth savings\n\nbestdemotivationalposters.com – 500 URLs, 9/10 score, 83% bandwidth savings\n\n\nTotal: 970+ URLs with verified performance.\n\nEnergy Efficiency\n\nHow much energy does TCT save?\n\nAt 10% adoption across top 10,000 sites:\n\n\n8,158 GWh/year energy saved\n\n4,079,057 metric tons CO₂ avoided\n\nEquivalent to 885,000 cars removed from roads\n\n\nHow is energy savings calculated?\n\n\nNetwork transmission: 0.06 kWh/GB reduced\n\nAI inference: 0.000187 kWh/token reduced\n\nScaled across projected adoption\n\n\nPatent & Licensing\n\nIs TCT patented?\n\nYes – US Patent Application 63/895,763 filed October 8, 2025 (Patent Pending).\n\nCan I use it on my website?\n\nYes – Free for all website owners. No license fee, no restrictions.\n\nWhat about commercial use?\n\nWebsite owners: Free. Large-scale AI companies/CDNs processing >10K URLs/month: Contact antunjurkovic@gmail.com for licensing.\n\nIETF Standards\n\nIs TCT being standardized?\n\nYes – Presented at IETF 124 GREEN WG (November 7, 2025) (November 2025) via the GREEN Working Group (energy efficiency).\n\nWhere is the specification?\n\nGitHub: github.com/antunjurkovic-collab/collab-tunnel-spec\n\nSupport\n\nHow do I get help?\n\n\nEmail: antunjurkovic@gmail.com\n\nGitHub: github.com/antunjurkovic-collab\n\nDocumentation: Integration Guide\n\nValidation: Online Validator","content_media_type":"text/plain; charset=utf-8","excerpt":"Frequently Asked Questions General What is TCT?
