AI Visibility Index: Aggregate & Stone Materials in California

Cell average

0.32of 15

Across all 74 tracked companies.

Top ten average

5.6of 15

The ten most visible companies in the cell.

A company's score is how many of the 15 measured answers named it.

These are the companies AI assistants named most often when California buyers went looking for a supplier in this category.

54 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

This is the first measurement of this cell, so there is nothing to compare it with yet. The next measurement will show what moved.

Stability is normal. AI answers in industrial categories change slowly, and a cell can go several measurements with no change in the top ten.

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1. 1“Best aggregate and stone materials companies in California”
2. 2“Who supplies washed construction sand and gravel in California”
3. 3“I need a California aggregate and stone materials partner for ongoing ready-mix concrete production, who should I talk to”
4. 4“Top aggregate and stone materials suppliers in California for civil construction buyers”
5. 5“Which California aggregate and stone materials suppliers can provide DOT-spec crushed stone and certified gradations”
6. 6“List 20 aggregate and stone materials companies in California with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.

These are the sources the answers in this cell leaned on most, ranked by how many of the named companies each one stands behind.

Enter a domain or a company name to see whether it is tracked in this cell, and whether the answers named it. This is a lookup against a measurement already taken, so it is instant.

The public Index publishes one measurement per cell. A monthly report covers your own company: every question it was named on, every question it was not, and what moved. Your own position is only ever shown to you.
