# Study summary (97 sites audited)

## Speed (91 sites with timing)
Lab measurements from DataForSEO's headless browser (390 x 844 viewport, scale factor 3, no network throttling). TTI, LCP, and DOM-complete are the median of up to 3 usable runs; every other field (word count, page weight, scripts, plain-text rate, CLS, HTTPS, OG) is taken from the first usable run. Not Lighthouse, not field data.

- Median LCP: 1672 ms; fastest 280 ms; slowest 7192 ms
- Lab LCP under 2,500 ms: 72.5% (66 of 91) (not a Core Web Vitals pass; CWV uses field data at the 75th percentile)

| Lab LCP | Sites | Share |
|---|---|---|
| Under 1,000 ms | 20 | 22% |
| 1,000 to 1,499 ms | 15 | 16.5% |
| 1,500 to 1,999 ms | 22 | 24.2% |
| 2,000 to 2,499 ms | 9 | 9.9% |
| 2,500 to 3,999 ms | 18 | 19.8% |
| 4,000 ms and over | 7 | 7.7% |

- Median TTI (DataForSEO-reported, data-center conditions): 1422 ms; mean 1635 ms; fastest 260 ms; slowest 6124 ms
- Under 500 ms: 12.1% (11 of 91); over 3,000 ms: 8.8% (8 of 91)

| TTI | Sites | Share |
|---|---|---|
| Under 500 ms | 11 | 12.1% |
| 500 to 999 ms | 15 | 16.5% |
| 1,000 to 1,999 ms | 39 | 42.9% |
| 2,000 to 2,999 ms | 18 | 19.8% |
| 3,000 ms and over | 8 | 8.8% |

- Usable timing runs per site: 83 sites with 3, 4 with 2, 4 with 1 (reported values are the median of the usable runs)
- TTI run-to-run spread over the 87 sites with 2 or more usable runs: median 1106 ms, 90th percentile 2554 ms (sites with a single usable run have no spread and are excluded)

## Associations with TTI (Pearson r over timed sites)
Weak values mean no meaningful linear association; they do not show that a field predicts or does not predict speed.

| htmlBytes | 91 | -0.23 |
| transferBytes | 91 | -0.2 |
| scriptsCount | 91 | 0.07 |
