Methodology and sample sizes

Businesses: listings with a phone number, graded as on-trade, with opted-out businesses removed (124 rows).
Website / no website: whether the map listing names a website (106 do, 18 do not).
Email: an address read from the company's own website (43). Verified means the mail server confirmed the mailbox over SMTP; nothing is sent (13 of the 43).
Site down of checked: of the 83 listed websites our crawler tried to load, the share where no page loaded (15). Sites not yet tried, or whose robots.txt asked us not to, are not counted either way.
Toll-free phone: the listing's main number is an 8xx toll-free number (5).
Owner name: an owner named on the company's site (8).
Median rating and reviews: over the 124 listings with a Google rating.
Percentages are rounded to the nearest whole percent; "under 1%" means at least one but less than half a percent.
