Most sites pass LCP. When they fail, look at the server and late discovery before you touch the image format.

2.8s Worst 10% of sites

86.1% of sites pass LCP. The typical site sits at 1.4s. The worst 10% are above 2.8s.

Field LCP from Chrome, joined to a technique crawl of the same origins. Every rate and ranking below is computed from this edition. Nothing here is a controlled experiment.

Cohorts, not A/B tests. Sites that adopt a technique are not randomly assigned. Read the gaps as associations, then verify on your own traffic.

The state

LCP distribution and percentiles

How CrUX LCP is spread across desktop sites, from the fastest to the slowest.

Most desktop sites pass LCP. 86.1% sit at or under 2.5s. The typical site is at 1.4s, and 75% of sites stay under 2.0s. Only 13.9% fail LCP. The slowest 10% are above 2.8s, and the slowest 1% are above 5.4s.

The break

Explore the sub-phases of LCP

LCP is four sub-phases: TTFB, load delay, load time, and render delay.

LCP breaks into four sub-phases. On the typical site they add up to 1.3s, still under the 2.5s good bar.

TTFB is the longest at 647ms. That is almost half the path (48.6%). Load delay is second at 318ms (discovery of the hero). Render delay is 224ms. Download (load time) is the short one at 142ms.

TTFB is also the most interesting. It tracks CrUX LCP hardest (corr +0.64). When the server stretches, pass rate falls. The 50% cliff sits near 1.9s of TTFB. Load delay is next (+0.42). That is late discovery, not a heavy image file. Across sites, the image download is rarely the whole problem.

The mechanism

How the browser finds the hero

Late discovery shows up as load delay. Background images and script-injected heroes are the common paths.

The stack

CMS: pass rate and phase anatomy

A high pass rate can hide a different budget. Some platforms pay the server. Others pay discovery after a fast first byte.

What moves LCP (and what does not)

Which techniques actually separate pass from fail

Every row is the same fleet, split by a technique signal. Gap is best minus worst variant with at least 300 sites. Five points or more is a separator this edition. Under five points, the signal is real in labs and still weak as a fleet-level LCP story.

This edition the separators are Discovery path, Image format, Responsive markup and Element type. Ranked by gap: Discovery path (+13 pp), Image format (+7 pp), Responsive markup (+6 pp) and Element type (+5 pp).

Under the 5-point line: loading attribute on the LCP, Priority hint on the LCP and 1P vs 3P LCP origin. Fix them when you see them on a real page. Do not expect them to rewrite the fleet LCP story.

Scoreboard: best vs worst cohort on field LCP

Only variants with at least 300 sites. Gap under 5 points is marked weak for this edition.

Looks important, barely separates pass from fail

Weak this edition (under 5 points)

Still worth fixing on a single site. As a fleet LCP separator, they do not clear the bar.
