Both of these organizations are extremely disruptive in nature – Amazon and Walmart. And, with this tutorial on twitter sentiment analysis using R, I wanted to see how Twitterverse feels about Amazon when you compare it with Walmart.

Mining Twitter for Sentiment analysis using R

Twitter is my obvious choice when it comes to quickly source data for sentiment related work. In this tutorial, I am using Twitter search API as opposed to Twitter streaming API. For understanding difference between the two, checkout this blog of mine that highlights the differences between Twitter streaming API vs Twitter Search API. Read more

A/B Testing Facebook Ads with Python – Split testing for eBook landing page [Part 1]

It has been more than 2 years since I’ve written anything over here. Feels great to write again! This is Part-1 of my series on data-driven A/B testing of Facebook ads using Python.

I’ve run thousands of campaigns from scratch, and often ideation and scalabilty was just one part of it. The other part that marketers underrate is quantitative and qualitative assessment of success/failure metrics.  Read more

Mobile app marketing case study

App marketing a/b testing

Ever wondered why people still make apps for a niche that already has a ton of apps with little to no space to squeeze in? Well, for the most part entrepreneurs, product managers and marketers all know a little secret – There’s always a possibility!

Most people will be surprised to see how quickly these folks can identify and calculate an opportunity. If you are interested in identifying/validating your own idea, hop over to Noah Kagan‘s interview by Tim Ferris and do it yourself.

When it comes to market an app idea, most usually follow the same basic pre launch and post launch strategies: App store optimization, PPC ads, Blog mentions/Press coverage, Social media marketing and other usual stuff. While, all of these steps are necessary and shouldn’t be ignored, app marketing is about getting more creative with your efforts.

Mobile app marketing should be creative

Why is there such a need to get creative?
1. It helps you innovate.
2. Play store search is broken. I myself have often found Playstore not being able to lead towards an app I searched for, while searching on Google search easily gets me there (quickly!). You need to make sure that you get discovered on Playstore, creativity helps you get discovered easily.

Further, even if you use app store intelligence tools which are a bit pricey, you won’t be sure if those results are accurate. If only creative mobile app marketing had a book written on it, right? I wish for such a book too! Most of these creative app marketing practices are black hat and are almost buried in depths of Google search. But, if you look at the playstore closely, you might actually end up finding a few of them. Although, it still would be difficult for you to draw a clear line there.

A reddit user ‘Rudolf895′ accidentally came across a network of apps that appear to have the same functionality, shared the same app screenshots, and were infact from the same developer.
Here’s the screenshot that he shared

App marketing tricks

Here’s something that I noticed about these apps:
1. Apps with same functionality but different name had different ratings.
2. These apps had almost all possible combinations that a prospective user might feed into the search bar.
3. The logo variation was very strategically placed for A/B testing.

Even though Playstore is against duplicate content, this developer was able to circumvent and perform his A/B testing without any problems. Only one of these app had a brand name associated with itself – Zoemob Family safety.

A layman’s first speculation would be that this app developer is trying to own the app results, while in my opinion this was just an A/B test to get the best results. And now that it is almost a year since this screenshot was discovered, and all duplicate apps except for the brand name one are gone.

A year ago, Zoemob used a different logo while they were testing:
App marketing a/b testing

The current logo that they are currently using belongs to one of the duplicate app’s logo, see for yourself:
App store optimization logo

With 60,000+ ratings and more than a million downloads on Play store, the strategy has worked quite well.

I am not actually recommending going blackhat to get a million users for your app, but the point is creativity works well with marketing and product development efforts. Even Unicorns like Airbnb once relied on bots to get users. In the words of Andrew Chen:

A traditional marketer would not even be close to imagining the integration above

That’s all for this post, hope I helped you in someway. Have something to say? Drop me a comment!

Information dashboard design – Best Practices

I love data, and after a couple of research projects and ML algorithms I cannot disagree with the importance of information visualization. So do most of the businesses that utilize information dashboards on a daily basis to trace, understand or even analyze things.

Since, information dashboards are mainly an ‘Enterprise thing’, many lack the user experience end users deserve. The same way we get badly designed enterprise softwares, we get badly designed information dashboards too. It happens!

But it’s not all dark and gloomy. There are products like Toutapp, who provide awesome dashboard with the right user experience. Question is how can you do the same for your information dashboard? While, pointing out specifics is difficult, there are some general rules that could simplify the user experience.

Information dashboard design – Some general tips

Visual Consistency
Consistency is often a designer’s best friend, and a consistent user interface would help users rely more on recognition and less on recalling. If you don’t know the difference already, recognition is better than recalling in this case. An excellent read on recognition and recall by nngroup.

Establishing hierarchy
While you are utilizing consistency in design to help a user easily move forward without having the need to recall much, you still need to separate the most important information from the rest. Imagine a case when to navigate to the most important section a user has to look at each section and read all text to identify them.

Edward Tufte’s design principles
Often regarded as the god of information visualization, what Luke Wroblewski is to design of forms – Edward Tufte is for data visualization. He recommends to optimize data-ink ratio, reduce chartjunk and myriad of other data visualization parameters that great simply complex information in a very easy to digest form. Here’s a good read on Tufte’s principles that you can include in your design.

No calculations
Dashboards are designed for a reason – To present the data in a digestible way. If your information dashboard design makes a user perform calculations then it probably isn’t doing the job right. Therefore it is recommended that you design while keeping the end user in mind. This will take care of all pains and frustrations of the user.

Design methods for product planning, scoping and development – Part 1

Brain storming origami

To build more meaningful products we need a user centered design approach. This new blog series outlines some of these design methods which could lead to products that users love. Depending on your use case, you can incorporate these design methodologies.

Brainstorming by graphic organizers

Brainstorming using Graphic organizers helps teams generate out of the box solutions and discover more problems by utilizing free spirited and quantity intensive frameworks. When utilized properly it helps bringing ideas out quickly and often uncovers the more unexplored ways to solve a design problem.

These brainstorm graphic organizing frameworks are available in the following frameworks: Brainstorming webs, Tree maps and Flow Charts. Consider the following when selecting a framework from the three frameworks:

  • To shape an idea brainstorming webs are often found to helpful.
  • To establish hierarchical relationships Tree maps are instrumental.
  • To better shape your idea and understanding it as a cohesive system dependent on elements Flow charts are usually helpful.

    The practice ensures that everyone is on the same page by using paper cut out models that illustrates the system. As opposed to digital models, the paper cut out representations are often more intuitive in understanding mental models.

    In this design methodology, pieces of paper are placed either on a horizontal whiteboard or a big white sheet of paper. The whiteboard or big white sheet of paper has marked areas. The cut out paper pieces who may represent people, groups, etc are then placed on top of these relevant areas. These areas are then connected with lines to illustrate flow and establish relationships.

    For now, the post will end with just the two design methodologies, but other design methods will follow soon.

  • Buster Keaton should be an inspiration for ux designers

    Watch a lot of movies and you love designing too? Well, you should know Buster Keaton. I have always been a fan of his work. When traditional cinema relied way too much on titles, he was the one who was focused on visual representations to connect with his audience.

    His awesome camera placements and exceptional talents brought a lot of value to modern day cinema. Keaton made his videos based on what would be the best for the audience.

    Buster Keaton(October 4, 1895 – February 1, 1966)
    Buster Keaton

    Keaton applied methods in his videos which really show us how to build anything that your audience will love. Look at how well crafted some of this scenes were.

    You don’t tell Buster Keaton he can’t do a stunt.

    Our work as designers and product owners should be to make intuitive experiences like Buster Keaton. Here’s a great video from the Youtube Channel “Every frame a painting” about Keaton that’s a must watch.

    Cheers!

    Kindle – The best Ebook reader

    I am a book worm and I love to read as much as I can. My reading interests often makes me to import books out of the country, and often that’s unpleasant. The entire system to import books is just awful for an avid reader. After a good time utilizing Printed books and reading ebooks on PC’s and Tabs I switched to Kindle.

    Kindle best ebook reader

    The best ebook reader

    It has been years now, and since then I haven’t regretted my decision. Kindle is an awesome device for someone who loves to read. The entire product speaks of a design that’s well crafted for book readers. Here’s what I love the most about my Kindle.

    User experience of Kindle

    Kindle follows the typical book convention. While it doesn’t have those swipe animations which were present initially in the Galaxy Tab devices, it does follow the exact page flipping science which allow users to go back and forth between the pages. I remember not having to refer to any guide or check any instructions to learn those interactions, the user experience of Kindle feels extremely natural.

    Screen Quality

    When I unpacked my Kindle years ago, I’d no idea of what I was getting into. I opened the box and it appeared to me that there was a cover made of paper on my Kindle’s screen. When I tried to remove that cover I found that it was the actual screen of my Kindle! How awesome is that?
    300 ppi E Ink Carta display makes the screen well suited to our eye. For someone like me who wears high power spectacles, this combination bring more comfort.

    Screen brightness

    Again, another awesome feature that distinguishes Kindle from any other eReader. Kindle allows user to adjust screen brightness to match almost any light conditions, whether it be day or night.

    Light weight

    Being extremely light weight renders it as one of the easy to use devices. Using Kindle allows you to read for long time without tiring your hands.

    Battery

    I read at least for an hour on my Kindle, and still, it only needs to be charged after 20 days. As opposed to our cellphones, which demands charging at least once in 2 days, Kindle only needs to be charged once in a month.

    .Mobi format

    The biggest pain in reading digital books is that you often need to pinch/zoom to adjust the layout, and you need to do it very often. Kindle straightaway takes that pain away. It brings a huge number of publishers to a platform with books perfectly optimized to provide the perfect layout without any need to re adjust the layout. Kindle also provides the facility to adjust font size and typefaces to your reading needs. Adjusting typefaces brings a bit more affordance in reading, e.g. if you are reading a novel you might want to switch to a typeface that facilitates that kind of reading. Latter one only applies to people who understand typefaces.

    Last but not the least, I’ve had Plastic cased Samsung Flagship phones in past which felt unnatural on a users’ hand and have an iPhone whose metal body makes it so slippery that it often falls from my hand. Whereas, Kindle is nicely design, the back portion feels extremely good on hands and takes good care of these usability issues.

    Is Kindle the best ebook reader? Yes, Definitely it is!
