Real 404s, JSON-LD and initial HTML differ by about two points or less, and robots.txt lets agents in slightly more often lower down the list. All 100 band rates are here. ## Ten checks in ten bands Each panel is one crawl check. The line runs across the ten bands, from ranks 1 to 1,000 on the left to ranks 9,001 to 10,000 on the right, and every panel uses the same scale from 0 to 100 percent. The same line sits in the pass rate column of [the checklist table](https://agentreadychecklist.com/). robots.txt allows all 17 agent tokens at / 71.2% overall robots.txt blocks no search or user-fetch token 73.2% overall Home page has an h1 and 50 words in the initial HTML 64.0% overall A missing path returns 404 or 410 66.5% overall /llms.txt exists 14.3% overall Home page links to llms.txt 1.3% overall Accept: text/markdown returns text/markdown 3.4% overall Home page carries JSON-LD that parses 47.4% overall OpenAPI linked from the home page or served at /openapi.json 0.5% overall /.well-known/mcp.json serves JSON 0.4% overall Reachable sites in the Tranco top 10,000 on which the check ran, crawl of 2026-11-04. A band holds between 524 and 859 tested sites, so a gap of a few points between neighbouring bands is not a trend. Numbers behind the chart | Rate | 1 to 1,000 | 1,001 to 2,000 | 2,001 to 3,000 | 3,001 to 4,000 | 4,001 to 5,000 | 5,001 to 6,000 | 6,001 to 7,000 | 7,001 to 8,000 | 8,001 to 9,000 | 9,001 to 10,000 | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | robots.txt allows all 17 agent tokens at / | 67% | 66% | 74% | 74% | 73% | 73% | 69% | 75% | 71% | 70% | | robots.txt blocks no search or user-fetch token | 70% | 69% | 76% | 76% | 74% | 74% | 71% | 77% | 73% | 71% | | Home page has an h1 and 50 words in the initial HTML | 61% | 66% | 68% | 66% | 60% | 64% | 66% | 64% | 64% | 61% | | A missing path returns 404 or 410 | 68% | 65% | 67% | 71% | 67% | 66% | 64% | 69% | 67% | 63% | | /llms.txt exists | 20% | 12% | 19% | 16% | 15% | 15% | 14% | 14% | 10% | 10% | | Home page links to llms.txt | 2% | 1% | 2% | 1% | 2% | 1% | 2% | 0% | 1% | 1% | | Accept: text/markdown returns text/markdown | 4% | 2% | 4% | 5% | 4% | 4% | 2% | 3% | 3% | 3% | | Home page carries JSON-LD that parses | 49% | 46% | 51% | 50% | 42% | 46% | 49% | 52% | 45% | 44% | | OpenAPI linked from the home page or served at /openapi.json | 1% | 1% | 0% | 1% | 0% | 1% | 0% | 0% | 0% | 0% | | /.well-known/mcp.json serves JSON | 1% | 1% | 1% | 0% | 0% | 1% | 0% | 0% | 0% | 0% | ## What the bands show The table sorts the checks by the gap between the three top bands (ranks 1 to 3,000) and the three bottom bands (ranks 7,001 to 10,000). A positive gap means the more popular sites pass more often. | Crawl check | Top 3 bands | Bottom 3 bands | Gap | Rows | | --- | --- | --- | --- | --- | | /llms.txt exists | 16.6% | 11.3% | +5.4 | AR-READ-07 | | robots.txt allows all 17 agent tokens at / | 69.0% | 71.9% | -2.8 | AR-FIND-01 | | robots.txt blocks no search or user-fetch token | 71.7% | 73.8% | -2.1 | AR-FIND-01, VERCEL-ROBOTS-EXCLUSIONS | | Home page has an h1 and 50 words in the initial HTML | 65.1% | 63.0% | +2.1 | AR-READ-01, AR-READ-03 | | Home page carries JSON-LD that parses | 48.7% | 47.2% | +1.5 | AR-READ-08 | | Home page links to llms.txt | 1.6% | 0.9% | +0.7 | AR-READ-06, AR-READ-07 | | Accept: text/markdown returns text/markdown | 3.3% | 2.9% | +0.4 | CF-MARKDOWN-NEGOTIATION, AR-READ-09 | | /.well-known/mcp.json serves JSON | 0.6% | 0.2% | +0.4 | AR-ACT-03, AR-ACT-10 | | OpenAPI linked from the home page or served at /openapi.json | 0.7% | 0.3% | +0.4 | AR-ACT-02, AR-READ-06 | | A missing path returns 404 or 410 | 66.4% | 66.1% | +0.3 | AR-READ-02 | Only llms.txt presence shows a gap above three points: 16.6% in the top three bands against 11.3% in the bottom three. The robots.txt check runs the other way, 71.9% in the bottom bands against 69.0% at the top, a gap of 2.8 points. For the rest, rank does not separate the sites that pass from those that fail, so the work is the same for a site at rank 50 and one at rank 9,500. ## Download - [pass-rates-by-rank-2026-11-04.csv](https://agentreadychecklist.com/data/pass-rates-by-rank-2026-11-04.csv)One line per check and band: tested, passing and share.
