Blogger Magic - Stats Accuracy And Consistency

One of the least understood Blogger features is the Stats visitor counters, and the various displays.

We see the confusion, in Blogger Help Forum: Get Help with an Issue, periodically.

The "weekly" Stats numbers don't add up, properly!

or

Why is "Popular Posts" so out of touch, with reality?

Magic is fun to watch, when it's just for amusement. When your numbers seem to have magical quality - changing from day to day, or display to display - it becomes annoying.

With its many lines and pages, the various Stats displays look like they could be part of one big balance sheet - but they are not.

With a balance sheet, you'll have detail lines in one page, that can be added up and reconciled against totals, in another page. This makes some balance sheet components redundant.

With Stats, nothing is redundant. Whether provided in a dashboard page, for you to examine - or in a gadget, to encourage your readers - all numbers are significant, exactly as displayed.

What you see for each day cannot be added up and balanced against a week - nor can a collection of weeks add up to a month. Nor can detail lines in "Pages" add up to totals, in "Audience".

• Components and features are provided for different purposes.
• Different dashboard pages reflect different details.
• Time periods do not begin and end equally.
• You may, or may not, be able to ignore your own pageviews, consistently.

Components and features are provided for different purposes.

The "Popular Posts" gadget displays popular posts, for the convenience of the blog readers - and there is no "Popular Pages" gadget, for people who choose to build a blog, based on static pages. The dashboard Stats pages are displays for informing the blog owner.

The (3) time range selections in "Popular Posts" also differ from the (5) selections in the dashboard Stats pages - further preventing comparison between Popular Posts and dashboard displays.

Different dashboard pages reflect different details.

The "Posts" dashboard page lists (only) the 10 most popular posts ("dynamic" pages), and the 10 most popular pages ("static" pages). "Pageviews today", and "Pageviews yesterday" reflect all blog activity - all index pages, all "pages", and all "posts" together.

Time periods do not begin and end equally.

"Pageviews today", and "Pageviews yesterday" counts are reset based on the global day - not on any local clock. Your "today" will never be the same, all days of the year - if ever. 23 / 24 of the world will never see their "today" equal to "Pageviews today", and "Pageviews yesterday".

And everybody knows that weeks, months, and years never begin and end in synch. You cannot add up weeks into months - nor months into years.

"Pageviews today", and "Pageviews yesterday" are the best known objects of confusion - but by no means the only - in the Stats data complement.



You may, or may not, be able to ignore your own pageviews, consistently.

Even given the recent improvement to the "Don't track" option, not all blog owners will be able to ignore their own pageviews. Every blog owner has their own required complement of performance and security products, which may interfere with the Stats "Don't track" code.

The bottom line.

Everybody needs to accept reality - that Stats will simply perform differently, for every different blog, and for every different owner of every team blog. Enjoy and use Stats for what it is.

Many #Blogger blog owners become concerned, when they add up detail Stats numbers on one display, and find the numbers do not agree with the totals from another display. They do not notice that the numbers have different origins, and purposes - and simply cannot add into any different display, with any degree of accuracy.

Stats Displays Pageviews - Not Unique Visitors

Too many blog owners do not understand the unique capability of Stats - nor do they understand its limitations.

We see the periodic question in Blogger Help Forum: How Do I?.

How do I find out how many actual people are viewing my blog?

Stats does not provide unique visitor counts - Stats provides pageview counts.

It's simply not possible to determine, with 100% certainty, how many different people are viewing your blog.

Consider these environments, where multiple locations, or people, are involved.

• A single person can use multiple computers, simultaneously.
• A single person can use a mobile computer, moving from one cellular connection to another.
• Multiple people can view the same computer, simultaneously.
• Multiple people can share the same computer, serially.
• Multiple people can share the same Internet connection, serially.

There are other visitor meters besides Stats - and some other such products will provide "unique" visitor counts. Each product, which claims to provide "unique" visitor counts, will do so based upon specific limitations and techniques.

One of the most obvious ways to determine unique visitors is by comparing IP addresses. Surely, two pageviews from the same IP address will be one person - and two pageviews from two different IP addresses will be two people, right? Wrong.

• One person can use two computers, simultaneously.
• One person can use a mobile computer, moving between two locations (each location will have a different IP address).
• Two people can use the same computer, at a library or Internet cafe.
• Two people can use the same mobile Internet connection.

In each of these cases, one person may look like two people - or two people can look like one person.

It's even possible that two people can access the same page, from the same computer, one after the other. If the first person does not properly clear the computer, after use, the second page access will be from cache - and will not access the server. The second person, using that computer, will not show up in a Stats log. Again, two people can look like one.

Some visitor logs will drop cookies onto a computer. Detecting a cookie already in place, this indicates one person, returning - and successfully dropping a cookie, indicates a different person, right? Wrong, again.

• Again, a shared computer is a possibility.
• Not all computer owners will permit unknown websites to drop cookies, onto their computers.
• And some owners, when they permit cookies on their computers, will periodically clear cookies.

Some very sophisticated visitor logs can compare demographic details, similar to the Stats Audience display. Besides IP address, what can be determined?

• Operating system, brand, model, and version.
• Browser brand, model, and version.
• Maybe, location (possibly determined by IP address, again).

And finally, some visitor logs will compare IP address, over a given time interval. Arbitrarily deciding that all activity from the same IP address, over a period of 30 minutes, represents a statistical "single person", is a known technique. This is not a legally significant technique, however.

The bottom line is, as I state repeatedly, you simply cannot compare numbers from any two visitor logs or meters, with any degree of usefulness. Each product will have its own way of determining unique visitors - when they even suggest a "unique" visitor count. Stats simply avoids the uncertainty, and only provides pageview counts.

Stats Pageview Counts Fluctuate Daily, Not At Midnight

One of the many controversial issues about Stats involves the daily pageview counts, which are reset daily.

Most blog owners accept the daily count reset, in principle - they just don't understand why the counts should be reset during their day, instead of at midnight.

My pageview count goes up during the day - but in the afternoon, it goes to zero, then starts over again. Why is Stats so unreliable?

The pageview count reset would be better understood, were it to happen daily, at midnight, for each blog owner. Unfortunately, there are over 24 different time zones, worldwide - and Blogger blogs are surely owned by some persons, in each of the time zones represented.

There are 24 time zones which roughly follow longitudinal lines - plus specific countries which have their own national clocks. WikiPedia identifies a total of 40 time zones.

Some countries span multiple time zones, adding to the 24 longitudinal zones.

Some countries span and divide into multiple time zones, others span multiple time zones and use one time zone. India, for instance, spans 3 time zones, geographically - but observes one time zone, offset by 30 minutes, as "GMT+5.5".

Most people observe a twice yearly 1 hour clock shift.

Many countries observe a seasonal variation, "Daylight Savings Time", when they shift local clocks ahead or behind, by an hour. DST beginning and ending dates vary by country, irregularly.

Also, countries south of the equator start summer, when countries north of the equator start winter. People south of the equator move their clocks forward, when people north of the equator are moving theirs backwards. If you ever try to communicate with somebody in Australia, from the USA, you'll notice how much relative fluctuation this causes, during a year.

To reset Stats at midnight for everybody, there would be pandemonium.

If the daily Stats pageview count reset were to be scheduled according to the local clock of the blog owner (which would be impossible, for multi owner blogs), there would have to be as many reset process schedules as there are countries / time zones. Additionally, twice a year, most reset schedules would be shifted, according to the local DST offset.

The only practical solution is to reset at the same time, worldwide.

Considering the almost inestimable number of rules required to schedule a local midnight count reset for all Blogger blogs, during the entire year, I suspect that the only practical design involves scheduling the reset, for all blogs, at midnight GMT. This means that no blog owners will see their pageview counts reset at midnight, during the entire year.

Everybody simply has to accept their count being reset sometime during their day - with the reset time varying according to the twice a year local clock shift.

Some #Blogger blog owners claim that Stats daily totals seem to go up, and down, during the day. They do not understand why Stats counts are reset during their day, instead of at midnight their time.

Fluctuations In Stats Pageview Counts And Newer Blogs

Some owners of newer Blogger blogs spend time reading their Stats logs, and worry that their "All time" pageview counts don't always go up - they go down, too.

Why do the counts go down? Is there one number, that I can believe?

They don't understand that with Stats, you need to look for trends - not absolute readings. In the beginning, fluctuations are more obvious, and trends are less obvious.

Thanks to the referer spam war, and to normal visitor activity, even the "All time" numbers will go up and down - for newer blogs, which have less genuine and constant visitor traffic. And the constant rise and fall is scary - until you get used to it.

Newer blogs have less established readers, which makes spikes in both the periodic referer spam, and normal visitor activity, more visible.

With the 4 limited time ranges (Now, Day, Week, and Month), the spikes will "move" in and out of context - and make pageview counts in these time ranges fluctuate. When a spike in numbers "moves in" to a time range, the pageview counts will rise, suddenly. When a spike "moves out" of a time range, the counts will fall, just as suddenly.

With newer blogs, the fluctuations exert a "double whammy".

1. The fluctuations are more visible, because overall genuine visitor activity is lower. Less readers = less visitor activity.
2. Worrying over the fluctuations takes time away from working on the blog. Less time working on the blog leads to less blog content, attracts less new readers, and leads to less visitor activity.

More experienced blog owners know to use Stats to watch for trends - not immediate numbers.

The answer here is simple. Monitor Stats periodically - not constantly. Watch for trends, and learn how to interpret the trends. Spend more time working on your blog, because that's where the value of your blog lies.
