How Indian Brands Drive Conversions On Independence Day

How Brands Drive Conversion on Independence Day

The Indian Independence day is right around the corner. For consumers in India, it’s a day of rejoice and celebration. And, for marketers, it opens a box of opportunities.

For marketers, the opportunity to leverage spirit of Independence translates into consumers’ buying decision for marketers.

In India, especially during major festivals and occasions like Independence Day, you can expect cutthroat rivalry among major brands. And yet, there are big winners in such intense situations.

How does this happen?

What are the strategies and tactics that these brands deploy to successfully pull off a nationwide campaign?

We studied various campaigns of India’s largest online brands to find out the answer.  

And we saw that there were five different ploys deployed to pique the interest of the average online consumer in India that resulted in the success of these campaigns.

1. Tapping into consumers’ emotions

Independence Day is the time of the year when citizens are filled with joy and hopes for prosperity for the whole nation. Marketers very well understand these emotions and know how to leverage these to their advantage.

A fitting example would be the outstation campaign by Ola, one of the largest cab aggregator in India.

When the Independence day is close to a weekend, people love to travel a lot. Weekend getaways are popular among the public, and folks love to spend time with their friends and relatives at places nearby.

Ola appealed to its customers’ emotions by offering them outstation deals during the Independence week. The company even offered an INR 300 discount for its first-time outstation users. Ola also partnered with Club Mahindra and Yatra to offer deals on hotel stays.

Ola encourages taking a holiday while thinking about it as a viable brand for traveling to nearby getaways.

2. Limited Period Offer

The sad part of these festive sales and offers is that these need to end after a short span. These campaigns generally run from 2 to 5 days around the festival.

For example, Flipkart Freedom Sale which celebrates India’s spirit of Independence only ran for 4 days, so people had limited time to buy what they wanted to.

Most consumers plan their purchases for such special occasions to get the best deals for the intended product. For others, marketing events, sales, and giveaways always take place with an expiration date.

Setting up such a trigger pushes prospective buyers to make purchases fast, to avoid missing out on the deals.

3. Creating a Sense of Urgency with the help of Micro Events

Some brands build upon the limited nature of the sale and go out all guns blazing to create a sense of urgency.

On top of the limited nature of the sale event, there are few micro-events incorporated into the sale that runs for a few hours to minutes. These sales are exclusive to people who can decide and act fast as they come with an additional discount.

Amazon does this very well with their lightning deals, which generally last from 2-6 hours throughout the event (which itself is 4-day long). The lightning deals have an additional discount on an already stated discount. The catch is the limited time and the sense of urgency it creates.


If people have to buy a product which has a lightning deal, they can add it to their cart and checkout under 15 minutes or the deal is gone forever.

4. Exclusive Product Launch

These festive events also leverage their audience’s interest by providing exclusive product offers during a sale.

It is highly useful to build anticipation among shoppers. And, in India, Amazon attracted consumers from the smartphone market. India is known as the mobile-first country, where over half the population owns a smartphone.


Amazon saw huge boosts in sales due to Smartphone and had exclusive launch of various devices such as Blackberry KeyOne, LG Q6, and the Oneplus 5’s Soft Gold variant. The result was a massive 10X increase in the sales for Amazon through just their Big Indian Sale Event.

5. Omnichannel Promotion and User Experience

Most major brands understand their users and customers. India is predominantly a mobile-first market with a decent penetration when it comes to computers. People love to shop using their mobile devices as well as use their laptops or PCs to make a purchase.

And most users want omnichannel access to the brand of their choice. We saw that a major chunk of brands embraced this philosophy over the Independence week.

For instance, my primary communication happens on my cell phone and brands saw my interaction on cell phones were far more than the email or website and therefore most of the promo I received was over mobile push or in-app rather than through email or website.

Grofers Freedom Sale

Also, there were deals that promoted usage of multiple channels to buy products. Grofers offered an INR 100 discount to shoppers who were open to buying stuff using their mobile app.

Appeal to Your Customers’ Emotions; Don’t Stop Experimenting

Customers are spoilt for choices when the whole nation is celebrating. In these times, marketers need not be intimidated or overwhelmed by their customers. They have to leverage these emotions and keeping building experiences with the help of experimentation.

These are major strategies that have been successfully demonstrated by brands to be effective. You need to understand emotional cues of your customers and accordingly create an effective campaign.

By tapping into your customer’s cognitive tendencies, you can build healthy, long-term relationships with your customers.

Encrypting Blacklisted Words In WordPress With ROT13

Countless algorithms for encrypting data exist in computer science. One of the lesser known and less common encryptions is ROT13, a derivative of the Caesar cypher1 encryption technique.

In this tutorial, we’ll learn about ROT13 encryption and how it works. We’ll see how text (or strings) can be programmatically encoded in ROT13 using PHP. Finally, we’ll code a WordPress plugin that scans a post for blacklisted words and replaces any in ROT13 encryption.

If you own a blog on which multiple authors or certain group of people have the privilege of publishing posts, then a plugin that encrypts or totally removes inappropriate words might come in handy


ROT13 (short for “rotate by 13 places,” sometimes abbreviated as ROT-13) is a simple encryption technique for English that replaces each letter with the one 13 places forward or back along the alphabet. So, A becomes N, B becomes O and so on up to M, which becomes Z. Then, the sequence continues at the beginning of the alphabet: N becomes A, O becomes B and so on up to Z, which becomes M.

A major advantage of ROT13 over other rot(N) techniques (where “N” is an integer that denotes the number of places down the alphabet in a Caesar cypher encryption) is that it is “self-inverse,” meaning that the same algorithm is applied to encrypt and decrypt data.

Below is a ROT13 table for easy reference.

| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z | A | B | C | D | E | F | G | H | I | J | K | L | M |

If we encrypted the domain smashingmagazine.com in ROT13, the result would be fznfuvatzntnmvar.pbz, and the sentence “Why did the chicken cross the road?” would become “Jul qvq gur puvpxra pebff gur ebnq?”

Note that only letters in the alphabet are affected by ROT13. Numbers, symbols, white space and all other characters are left unchanged.

Transforming Strings To ROT13 In PHP

PHP includes a function, str_rot13(), for converting a string to its ROT13-encoded value. To encode text in ROT13 using this function, pass the text as an argument to the function.


echo str_rot13('smashingmagazine.com'); // fznfuvatzntnmvar.pbz

echo str_rot13('The best web design and development blog'); // Gur orfg jro qrfvta naq qrirybczrag oybt

Using ROT13 In WordPress

Armed with this knowledge, I thought of ways it might be handy in WordPress. I ended up creating a plugin that encodes blacklisted words found in posts using ROT13.

The plugin consists of a textearea field (located in the plugin’s settings page) in which you input blacklisted words, which are then saved to the database for later reuse in WordPress posts.

Without further fussing, let’s start coding the plugin.

Setting Up the Plugin

First, include the plugin’s file header2.


Plugin Name: Rot13 Words Blacklist
Plugin URI: http://smashingmagazine.com/
Description: A simple plugin that detects and encrypts blacklisted words in ROT13
Version: 1.0
Author: Agbonghama Collins
Author URI: http://w3guy.com
Text Domain: rot13
Domain Path: /lang/
License: GPL2

As mentioned, the plugin will have a settings page with a textarea field that collects and saves blacklisted words to WordPress’ database (specifically the options table).

Below is a screenshot of what the plugin’s settings (or admin) page will look like.

Settings page of the plugin.3
(See large version4)

Now that we know what the options page will look like, let’s build it using WordPress’ Settings API5

Building the Settings Page

First, we create a submenu item in the main “Settings” menu by using add_options_page(), with its parent function hooked to admin_menu action.

add_action( 'admin_menu', 'rot13_plugin_menu' );

 * Add submenu to main Settings menu
function rot13_plugin_menu() 
		__( 'Rot13 Blacklisted Words', 'rot13' ),
		__( 'Rot13 Blacklisted Words', 'rot13' ),

The fifth parameter of add_options_page() is the function’s name (rot13_plugin_settings_page), which is called to output the contents of the page.

Below is the code for rot13_plugin_settings_page().

 * Output the contents of the settings page.
function rot13_plugin_settings_page() 
	echo '<div class="wrap">';
	echo '<h2>', __( 'Rot13 Blacklisted Words', 'rot13' ), '</h2>';
	echo '<form action="options.php" method="post">';
	do_settings_sections( 'rot13-words-blacklist' );
	settings_fields( 'rot13_settings_group' );

Next, we add a new section to the “Settings” page with add_settings_section(). The textarea field we mentioned earlier will be added to this section with add_settings_field(). Finally, the settings are registered with register_setting().

Below is the code for add_settings_section(), add_settings_field() and register_setting().

	// Add the section

	// Add the textarea field to the section.
		__( 'Blacklisted words', 'rot13' ),

	// Register our setting so that $_POST handling is done for us
	register_setting( 'rot13_settings_group', 'rot13_plugin_option', 'sanitize_text_field' );

The three functions above must be enclosed in a function and hooked to the admin_init action, like so:

 * Hook the Settings API to 'admin_init' action
function rot13_settings_api_init() 
	// Add the section

	// Add the textarea field to the section
		__( 'Blacklisted words', 'rot13' ),

	// Register our setting so that $_POST handling is done for us
	register_setting( 'rot13_settings_group', 'rot13_plugin_option', 'sanitize_text_field' );

add_action( 'admin_init', 'rot13_settings_api_init' );

Lest I forget, here is the code for the rot13_setting_callback_function() and rot13_setting_section_callback_function() functions, which will output the textarea field and the description of the field (at the top of the section), respectively.

 * Add a description of the field to the top of the section
function rot13_setting_section_callback_function() 
	echo '<p>' . __( 'Enter a list of words to blacklist, separated by commas (,)', 'rot13' ) . '</p>';

 * Callback function to output the textarea form field
function rot13_setting_callback_function() 
	echo '<textarea rows="10" cols="60" name="rot13_plugin_option" class="code">' . esc_textarea( get_option( 'rot13_plugin_option' ) ) . '</textarea>';

At this point, we are done building the settings page for the plugin.

Up next is getting the plugin to detect blacklisted words and encrypt them with ROT13.

Detecting Blacklisted Words and Encrypting in ROT13

Here is an overview of how we will detect blacklisted words in a WordPress post:

  • A post’s contents are broken down into individual words and saved to an array ($post_words).
  • The blacklisted words that were saved by the plugin to the database are retrieved. They, too, are broken down into individual words and saved to an array ($blacklisted_words).
  • We iterate over the $post_words arrays and check for any word that is on the blacklist.
  • If a blacklisted word is found, then str_rot13() encodes it in ROT13.

It’s time to create the PHP function (rot13_filter_post_content()) that filters the contents of a post and then actually detects blacklisted words and encrypts them in ROT13.

Below is the code for the post’s filter.

 * Encrypt every blacklisted word in ROT13
 * @param $content string post content to filter
 * @return string
function rot13_filter_post_content( $content ) 

	// Get the words marked as blacklisted by the plugin
	$blacklisted_words = esc_textarea( get_option( 'rot13_plugin_option' ) );

    // If no blacklisted word are defined, return the post's content.
	if ( empty( $blacklisted_words ) ) 
		return $content;


		// Ensure we are dealing with "posts", not "pages" or any other content type.
		if ( is_singular( 'post' ) ) 

			// Confine each word in a post to an array
			$post_words = preg_split( "/b/", $content );

			// Break down the post's contents into individual words
			$blacklisted_words = explode( ',', $blacklisted_words );

			// Remove any leading or trailing white space
			$blacklisted_words = array_map(
				function ( $arg ) 
					return trim( $arg );


			// Iterate over the array of words in the post
			foreach ( $post_words as $key => $value ) 

				// Iterate over the array of blacklisted words
				foreach ( $blacklisted_words as $words ) 

					// Compare the words, being case-insensitive
					if ( strcasecmp( $post_words[ $key ], $words ) == 0 ) 

						// Encrypt any blacklisted word
						$post_words[ $key ] = '<del>' . str_rot13( $value ) . '</del>';

			// Convert the individual words in the post back into a string or text
			$content = implode( '', $post_words );

		return $content;

add_filter( 'the_content', 'rot13_filter_post_content' );

While the code above for the filter function is quite easy to understand, especially because it is so heavily commented, I’ll explain a bit more anyway.

The is_singular( 'post' ) conditional tag ensures that we are dealing with a post, and not a page or any other content type.

With preg_split(), we are breaking down the post’s contents into individual words and saving them as an array by searching for the RegEx pattern b, which matches word boundaries6.

The list of blacklisted words is retrieved from the database using get_option(), with rot13_plugin_option as the option’s name.

From the screenshot of the plugin’s settings page above and the description of the textarea field, we can see that the blacklisted words are separated by commas, our delimiter. The explode PHP function breaks down the blacklisted words into an array by searching for those commas.

A closure7 is applied to the $blacklisted_words array via array_map() that will trim leading and trailing white spaces from the array values (the individual blacklisted words).

The foreach construct iterates over the post’s words and check whether any word is in the array of blacklisted words. Any blacklisted word that gets detected is encrypted in ROT13 and enclosed in a <del> tag.

The $post_words array is converted back to a string or text and subsequently returned.

Finally, the function is hooked to the the_content filter action.

Below is a screenshot of a post with the words “love” and “forever” blacklisted.

A post with the blacklisted word love encoded in ROT138

Wrapping Up

ROT13 is a simple encryption technique that can be easily decrypted. Thus, you should never use it for serious data encryption.

Even if you don’t end up using the plugin, the concepts you’ve learned in creating it can be applied to many situations, such as obfuscating or encrypting inappropriate words (such as profanities) in ROT13, which would be a nice feature in a forum where people have the freedom to post anything.

Hopefully, you have learned a thing or two from this tutorial. If you have any question or a contribution, please let us know in the comments.
