Dave,thanks for sharing this, the referral data is particularly fascinating. I mentioned during the quarterly review that I'd love to get a better sense of (1) the proportion of requests in the mobile request logs lacking a referral, (2) the possible causes of this gap and (3) to what extent these missing entries introduce a bias in the referral ranking.The 3rd most popular query (according to your dumps) is ビッグダディ (japanese for "Big Daddy"), which presumably refers to this guy: http://metro.co.uk/2013/03/20/giant-japanese-spider-crab-big-daddy-arrives-at-blackpool-sea-life-centre-3550751/What's interesting is that there's no such entry on the japanese Wikipedia and I am baffled that people may have landed on the website via a search engine query for a non-existing article.Do you have an explanation for this or am I misinterpreting what you mean by search query?
As promised earlier today in the Analytics weekly showcase, I've got a few interesting bits of data to share from playing with the new Mobile Site Sessions dataset.
# Visits to Mobile Site, 4/21/2013
- Total Visits: 51,624,103
- Unique Visitors: 37,736,120
- Total Pageviews: 104,972,033
- Avg Pageviews per Session: 2.0334
- Max Pageviews in one Session: 141,882
## Standard Site
- Visits: 51,603,221
- Unique Visitors: 37,723,188
- Pageviews: 104,910,382
- Avg Pageviews per Session: 2.033
## Alpha Site
- Visits: 986
- Unique Visitors: 822
- Pageviews: 7,087
- Avg Pageviews per Session: 7.188
## Beta Site
- Visits: 19,896
- Unique Visitors: 16,235
- Pageviews: 54,564
- Avg Pageviews per Session: 2.742
- A session (or "visit") is defined as all activity with less than 30 minutes between each hit. Intuitively speaking, a session ends when the user hasn't done anything in 30m.
- As we do not set visitor_id cookies for all users, the "unique visitors" metric was calculated using hash(ip_address + users_agent) as visitor_id.
- This job looked at all requests to the mobile site on 4/21/2013, which is 75.17 GB of request logs.
- The job took ~17 minutes to process the day into 15.3 GB of sessions.
- The summary above took maybe 10 minutes to set up/write in Hive, and the job took maybe 7 minutes.
In addition to that summary, I ran a few jobs on the entry_referer field -- the URL that referred the user to us when the session started. Obvious caveats: this is only one day of data, and it's only the mobile site. Draw conclusions with care.
First, I pulled out the top referring domains. It's mostly as you'd expect -- search engines -- though you'll also note that several Wikipedia mobile sites show up. My working hypothesis is that people don't tend to close tabs on smartphones; when they later come back, it is often to an open Wikipedia tab: clicking a link or perform a search means the referrer is still us.
Since -- as expected -- so much of the data pertained to search engines, I also calculated the top search queries and top keywords that sent people to us. (For keywords, I've filtered out common "stop words": de, of, in, is, la, and, el, es, to, en, di, los, le, da, se, las, les, il, du, a, i, o, y, e.) In both, you see the predictable: lots of searches for porn, for "facebook", for "wiki", etc. But you also see a few things that surprised me:
- Tons of Japanese. Japan is the most mobile-enabled country in the world so I guess we should have expected to see many searches in Japanese show up in the top queries. I've left them URL-encoded in the results -- you'll see them as weird lines with % in them.
- Apparently people search for movies and TV so they can spoil their fun by reading about them on Wikipedia. Both of "movies" and "film" show up in the top keywords; Iron Man 1, 2, AND 3 all show up in the top search queries. I didn't expect this was a major use-case, but -- wikigroaning aside -- it's an interesting fact.
I'm sure we're only scratching the surface here. This is an exciting dataset, and I'm sure there's lots more to learn!
