  1 | ## What does it do?
  2 | It adds UTM, referrer, landing page and other information to any lead generation form. It adds this extra information
  3 | as hidden fields on a form.
  4 | 
  5 | Here's a blog post discussing it in detail: http://bit.ly/1z0r3dN
  6 | 
  7 | ## Why do I need it?
  8 | If you want to know where each email list subscriber or lead is coming from, use this script to help with that. This
  9 | is different from analytics tools where you know this information in aggregate.
 10 | 
 11 | e.g. You'll know that bob@example.com originally came from Twitter, landed on page www.yoursite.com/promotion and
 12 | visited your website 3 times before giving you his email address.
 13 | 
 14 | **Information it adds to your forms:**
 15 | * 5 UTM parameters - Any UTM parameters in the URL that a visitor used to come to your website will be added to the form
 16 | * 5 Initial UTM parameters (optional) - The UTM parameters in the very first URL that the visitor used
 17 | * Initial Referrer - The webpage where the visitor came from for the first time
 18 | * Last Referrer - The webpage where the visitor came from most recently
 19 | * Initial Landing page - URL of the page on your website where the visitor landed the very first time
 20 | * Number of visits - The number of times the visitor came to your website before filling your form
 21 | * Additional parameters defined in `additional_params_map`
 22 | * Additional initial parameters defined in `additional_initial_params_map`
 23 | 
 24 | ## How do I use it?
 25 | 
 26 | 
 27 | 1. Just add this before the closing `</body>` tag at the bottom of your page. Make sure to change the domain.
 28 | 
 29 |   ```html
 30 |   <script type="text/javascript" charset="utf-8">
 31 |     var _uf = _uf || {};
 32 |     _uf.domain = ".example.com";
 33 |   </script>
 34 | 
 35 |   <script src="https://d12ue6f2329cfl.cloudfront.net/resources/utm_form-1.2.0.min.js" async></script>
 36 |   ```
 37 | 
 38 |   There might be newer versions available in `dest` folder that are not yet available via CDN. Feel free to download the latest files in that case.
 39 | 
 40 | 2. You need to make your forms accept the new fields. Based on the information available for a visitor, the fields added
 41 |   to your form will be,
 42 | 
 43 |   * USOURCE - Value of *utm_source* if present
 44 |   * UMEDIUM - Value of *utm_medium* if present
 45 |   * UCAMPAIGN - Value of *utm_campaign* if present
 46 |   * UCONTENT - Value of *utm_content* if present
 47 |   * UTERM - Value of *utm_term* if present
 48 |   * IREFERRER - URL of the initial referrer
 49 |   * LREFERRER - URL of the last referrer
 50 |   * ILANDPAGE - Initial landing page
 51 |   * VISITS - Number of visits
 52 | 
 53 |   Note: A new visit happens when the visitor comes to your website after more than an hour (can be customized as shown below).
 54 | 
 55 | ## How will my form look like?
 56 | 
 57 | Let's say your lead generation form looks like this before the script is added.
 58 | ```html
 59 | <form action="//terminusapp.us6.list-manage.com/subscribe/" method="post">
 60 |   <label for="mce-email">Email Address</label>
 61 |   <input type="email" value="" name="email" id="mce-email">
 62 |   <input type="submit" value="Subscribe" name="subscribe">
 63 | </form>
 64 | ```
 65 | 
 66 | Once the script is added, your form will look like this after the page is loaded.
 67 | 
 68 | ```html
 69 | <form action="//terminusapp.us6.list-manage.com/subscribe/" method="post">
 70 |   <input type="hidden" name="VISITS" value="5">
 71 |   <input type="hidden" name="IREFERRER" value="http%3A//google.com">
 72 |   <input type="hidden" name="LREFERRER" value="http%3A//twitter.com">
 73 |   <input type="hidden" name="ILANDPAGE" value="http%3A//www.terminusapp.com/blog/">
 74 |   <input type="hidden" name="USOURCE" value="twitter">
 75 |   <input type="hidden" name="UMEDIUM" value="social">
 76 |   <input type="hidden" name="UCAMPAIGN" value="awareness">
 77 | 
 78 |   <label for="mce-email">Email Address</label>
 79 |   <input type="email" value="" name="email" id="mce-email">
 80 |   <input type="submit" value="Subscribe" name="subscribe">
 81 | </form>
 82 | ```
 83 | 
 84 | When someone submits the form, all the extra information is also sent along with the email address.
 85 | 
 86 | You'll need to make sure that your form can accept these values. If it is a Mailchimp form, configure it to
 87 | accept these fields. Same for ConstantContact, CampaignMonitor, Hubspot, ActiveCampaign or any other service.
 88 | 
 89 | ## Customize your forms
 90 | If you would like to customize how fields get added to your form, following options are available:
 91 | 
 92 | ```html
 93 | <script type="text/javascript" charset="utf-8">
 94 |   var _uf = _uf || {};
 95 |   _uf.domain                     = ".example.com";
 96 | 
 97 |   _uf.utm_source_field           = "YOUR_SOURCE_FIELD"; // Default 'USOURCE'
 98 |   _uf.utm_medium_field           = "YOUR_MEDIUM_FIELD"; // Default 'UMEDIUM'
 99 |   _uf.utm_campaign_field         = "YOUR_CAMPAIGN_FIELD"; // Default 'UCAMPAIGN'
100 |   _uf.utm_content_field          = "YOUR_CONTENT_FIELD"; // Default 'UCONTENT'
101 |   _uf.utm_term_field             = "YOUR_TERM_FIELD"; // Default 'UTERM'
102 | 
103 |   _uf.initial_utm_params         = true; // Enable the tracking of initial UTM Parameters
104 |   _uf.initial_utm_source_field   = "YOUR_INITIAL_SOURCE_FIELD"; // Default 'IUSOURCE'
105 |   _uf.initial_utm_medium_field   = "YOUR_INITIAL_MEDIUM_FIELD"; // Default 'IUMEDIUM'
106 |   _uf.initial_utm_campaign_field = "YOUR_INITIAL_CAMPAIGN_FIELD"; // Default 'IUCAMPAIGN'
107 |   _uf.initial_utm_content_field  = "YOUR_INITIAL_CONTENT_FIELD"; // Default 'IUCONTENT'
108 |   _uf.initial_utm_term_field     = "YOUR_INITIAL_TERM_FIELD"; // Default 'IUTERM'
109 | 
110 |   _uf.initial_referrer_field     = "YOUR_INITIAL_REFERRER_FIELD"; // Default 'IREFERRER'
111 |   _uf.last_referrer_field        = "YOUR_LAST_REFERRER_FIELD"; // Default 'LREFERRER'
112 |   _uf.initial_landing_page_field = "YOUR_INITIAL_LANDING_PAGE_FIELD"; // Default 'ILANDPAGE'
113 |   _uf.visits_field               = "YOUR_VISITS_FIELD"; // Default 'VISITS'
114 |   
115 |   _uf.additional_params_map      = {
116 |     affiliate: "AFFILIATE"
117 |   }; // Maps affiliate parameter to AFFILIATE form field
118 |   _uf.additional_initial_params_map      = {
119 |     affiliate: "IAFFILIATE"
120 |   }; // Maps the initial affiliate parameter to IAFFILIATE form field
121 | 
122 |   _uf.secure                     = true; // Enable secure cookies
123 |   _uf.sessionLength              = 2; // In hours. Default is 1 hour
124 |   _uf.add_to_form                = "first"; // 'none', 'all', 'first'. Default is 'all'
125 |   _uf.form_query_selector        = 'form[action="/sign_up"]'; // custom form selector. Default is 'form', to select any form.
126 |   _uf.decode_uris                = true; // Decode URLs before populating the form. e.g. use "https://" instead of "https%3A//".
127 |                                          // NOTE: This will decode the entire URL and, in rare cases, may have side effects.

132 | 
133 | ## More Questions?
134 | #### What happens if someone visits a bunch of pages on my website/blog before filling the form?
135 | It doesn't matter. As soon as they land on your website, the script saves the information in a cookie. This
136 | cookie is valid for 365 days. It adds this information to your form from the saved cookie.
137 | 
138 | #### What's the session length for?
139 | It's used to count the number of visits. If someone comes to your website after the session has expired, it will be counted
140 | as a new visit.
141 | 
142 | #### Can I look at the code?
143 | You are on Github and all the code is available above. Knock yourself out. Even better, send a pull request and we can
144 | make it better together.
145 | 
146 | ## Development
147 | Utm Form is written in CoffeeScript and compiles to Javascript.
148 | 
149 | ### Setup
150 | 1. Clone the repository
151 | 2. Make sure you have node and npm installed: `brew install node`.
152 | 3. Install the required packages: `npm install`.
153 | 
154 | ### Compiling
155 | 
156 | Run `gulp build`
157 | 
158 | This will compile the CoffeeScript and also minify it. The generated files can be found in `dest` folder.
