Yes. They did. That was the whole point.
They compared visits to Pornhub with the set of results from Gallup
which identified cities that consider themselves "very religious" to
those who identified themselves as "least religious".

Yes we do.
All Pornhub had to do was compare their porn visits from the different
cities already identified as "very religious" to "least religious".
Here's how GALLUP came up with their results.
From the GALLUP study:
Throughout the country in 2012, 40% of Americans were classified as
very religious -- based on saying religion is an important part of
their daily life and that they attend religious services every week
or almost every week.
Thirty-one percent of Americans were nonreligious, saying religion
is not an important part of their daily life and that they seldom or
never attend religious services.
The remaining 29% of Americans were moderately religious, saying
religion is important in their lives but that they do not attend
services regularly, or that religion is not important but that they
still attend services.
Relatively few metro areas match the national religiousness average,
instead reflecting substantial diversity, with a 60-percentage-point
range between the most and least religious cities.
This generally mirrors the variation in the average religiousness
among the states of the union.
Mississippi is the most religious state (58% very religious), while
Utah is tied with Alabama in second place.
Vermont (19% very religious) is the least religious state.
Complete data on religiosity for all 189 metro areas can be found on
page 2.
The most and least religious cities generally reflect the
religiousness of the state in which they are located, although there
are some interesting exceptions.
Utah, for example, is one of the nation's most religious states, and
two Utah cities -- Provo and Ogden -- are indeed among the most
religious cities in the nation.
But Utah's largest metro area, Salt Lake City, is significantly
lower on the religiousness list (47% very religious) than the other
two Utah cities. This most likely reflects Salt Lake City residents'
more urban, less Mormon nature compared with other Utah metro areas.
And, although Michigan as a state has below-average religiousness,
that state's Holland-Grand Haven metro area is tied as the nation's
fifth most religious...
Seventy-seven percent of Provo residents say they attend church
weekly or nearly weekly, while 18% say they seldom or never attend.
Residents of the Burlington area represent nearly a mirror image,
with 18% saying they attend church weekly or nearly every week, and
76% saying they seldom or never attend.
The 77% level of frequent church attendance among residents of Provo
is clearly exceptional; 63% of residents in Montgomery, Ala., second
on the church attendance list, say they attend church on a weekly or
nearly weekly basis.
