Online A/B Split Test Calculator
Posted by: | CommentsAre you running an A/B split test for a marketing, email, ppc, or direct mail campaigns and want to know if you have a statistically significant winner to go live with? I recently built a quick and easy online A/B split test calculator at www.SplitTestCalculator.com that will answer this exact question for you.
Please make sure that when you fill out the calculator with your test information that you then click on the calculate results button and look below it in the results section to see if you have a winner or not.
If the A/B calculator says that you have a winner, you can determine the winner very easily by just looking at the conversion rates of each of the panels and the one with the better conversion rate is your winner. If the A/B split test calculator results declare that you don’t have a winner then you will need to run your test longer, or run a different test.

Interpreting Google Website Optimizer’s Page Sections Report
Posted by: | CommentsGoogle Website Optimizer, the free multivariate and AB testing tool makes available to you two results reports when you are running a multivariate test; the Combinations report, and the Page Sections report. The Combinations report is easy to read and interpret for the most part (for simplicity purposes here, the pages are listed in order of best performance, and a statistically significant winner with a 95+% confidence level over the control will be highlighted in green), but the Page Sections report many people incorrectly use the data that is presented or are confused on what the report is actually providing. You MUST know how to correctly interpret this report; otherwise you could incorrectly make decisions from the data that can cost you potentially big-time down the road.
The Combinations report provides you with the performance data for all of your page combinations that you are testing and compares each page combination to your original page (the control) in order for you to determine what test page combinations are outperforming the original.

The Page Sections report on the other hand displays all of your page sections that you are testing and the elements within each section in order to show you the best performing page element for each particular section.

Here is the scoop on the Page Sections report.
Many times, when you are running a test you will notice that the best performing elements according to the Page Sections report are not the same elements that are present in your winning page combination. It’s not as simple as looking at the different sections and choosing all the “best” elements according to Google Website Optimizer Page Sections report and then rolling out a page that contains these elements. The reason being is that the performance of the elements in each section being tested as shown in the Page Sections report are not being calculated and presented in context with the other sections. By this I mean that the results of each element in each section are presented by how they performed against the other elements in that same page section. It’s not taking into account the context of all the other elements on the page when showing you the best performers. To see which the best elements are in proper context, view your Combinations report and look at the individual elements in your top performing page combination.
Confused?
Let me give you an example. If you are testing a main headline, and have 3 different versions:
- Control/original headline
- Test headline # 1
- Test headline #2
And the report shows that test headline # 1 is the best performing element in that area, it’s only reporting to you that between those 3 headlines, headline #1 is the best performer, but it is not taking into consideration how it interacts with the other elements on the page. It’s not saying that for the page you are testing, headline #1 is the best to use for the roll-out page, but instead – between those 3 headlines, headline #1 is the best performing if you are comparing just the performance of the headline itself. Headline #1 might perform the best out of the 3 headlines when compared to each other out of context with the rest of the page elements, but Headline #2 might perform the best in combination with all the other elements and therefore is the one you want to roll out with (but not necessarily reported this way in the Page Sections report). So please, don’t use the Page Sections report to pick out which elements to roll-out live with.
The Relevance Rating graphic (currently found to the left of each page section), alerts you to how much impact each section had on your test (as defined by your test’s conversion goal). It’s presented as a range, from 0 to 5, with 0 representing that the section had virtually no impact on conversions and a 5 as having a high impact on page conversions.
So while the Page Sections report is important to look at to understand what is happening between the different elements in the page sections themselves, and the Relevance Rating is important to look at to understand what page sections are providing what level of impact to page conversions, you should ideally only use this information to help you gain more insights into the test. Insights that will also give you further help in planning future testing of the page.
However, you will only want to roll-out the panel that is deemed the best performer according to the page Combinations report. Of course this is after you finish running your head-to-head follow-up test between your control and the best performing page combination to verify your results outside of the multivariate testing environment!
Google Analytics App for the iPhone – A Quick Review
Posted by: | Comments
The best Google Analytics App available for the iPhone right now is in my opinion without a doubt (and simply named) Analytics App.
Analytics App gives you complete mobile access to your Google Analytics data from your iPhone. Whether you have just one site profile and one Google Analytics (GA) account, or multiple accounts with multiple profiles, this iPhone app is something I believe you will really be happy with.
For the past two months I have been using Analytics App at least a couple times per day, be it to answer questions on the go for others (i.e. HiPPOS) or even just simply playing around with it for fun to satisfy curiosities. It’s intuitively easy to use with virtually no learning curve for the app itself. Basically just click and there’s your data. I wouldn’t use this for actual data analysis (and this in part because of the limitations of the iPhone itself) but it’s extremely handy and fun to be able to have on the go with you.
Before I purchased it though, I thought it might be difficult to view analytics data on the iPhone due to the screen size, but the interface fits the iPhone perfectly and the data surprisingly is extremely easy to view with no straining on the eyes, even the charts it displays are easy to view.
More than 40 Reports Are Available to You
Analytics App has 9 standard Google Analytics Overview Reports:
- Dashboard, Visitors Overview
- Traffic Overview
- Content Overview
- Event Tracking Overview
- E-Commerce Overview
- Site Search Overview
- Goals Overview
- Quick access Dashboard for Today’s data.
Plus, more than 30 detailed reports you can view by drilling down in each of the areas, for example Keywords, Visitor Loyalty, Top Landing Pages, Top Content, Event Actions, and the ability to view your Custom Reports that have already set up inside your Google Analytics account.
Unfortunately, and unless I am missing something, you can’t click on individual referring sites themselves to view them in the iPhone browser. And, URL’s are limited to 22 characters so in the Top Content Reports you’re not able see the entire URLS or click on them either, so if your URL’s are long and non-intuitive before the 22 characters are used up you may not be able to know which URL is being referred to (but you can always use the Content by Title report).
Viewing Multiple Accounts
I should note, that to view multiple accounts with Analytics App you’ll need to give access for one account to view the others – but this has to be done on GA website itself, or you do it the old fashioned way by logging-out and then log back in on the app for each account itself if you want to view different accounts (I want to emphasize this is for accounts, not profiles as all profiles under your account are visible and selectable when you launch the app).
Misc.
Security: Analytics App stores your GA username and password information locally on your iPhone for security reasons.
Date Ranges: I found that setting the dates to view your data for is actually easier than in Google Analytics using the standard iPhone scroll wheel (and setting it in GA is easy).
Cost
What impressed me the most before I purchased it was that not that it was only $5.99, or that its reviews were overall rather fantastic, but that they offered a money back guarantee via PayPal so I felt that the risk was minimal. I’ve purchased many apps that have left me disappointed, so this was a motivating factor to purchase it on the spot without further consideration.
In Conclusion
So with nothing to lose (your money that is), I would definitely recommend checking the Analytics App out, or if you know someone who already has it to try theirs out – you’ll be glad you did, the app itself is really well produced.
