# About Landing Pages

Landing pages (prelandings, landers) are the pages the visitors see before offers. Sometimes these landing pages can be the target pages and can even send leads to a tracker. Keitaro allows to use your own page with an HTML file (local landing pages) and an external service(landing pages with redirects).

# Creating a Landing Page

# Name

The name of your landing page.

# The way of showing a landing page

Local (recommended) — allows to upload your landing page archive, which will be automatically unpacked to a tracker’s root directory and this landing page will work without redirects. Pack a zip archive for a correct work.
Redirect — the visit to a landing page is made via a redirect.
Preload — a landing page is downloaded and is shown right on the campaigns URL. Redirect is not used. You can use macros in a landing page code.
Action — the visitor is sent to a landing page with a redirect performing a definite action.

# Group

The name of the group the landing page belongs to (if any).

# Landing Page Address (URL)

A full path to your landing page, e.g. http://site.com/page1.html. You can add parameters and macros to the address.

# Landing Page Types

# Local Landing Page

This type landing page is opened without any redirects and is opened faster than a preloaded landing.

You need an archive with all landing page files. There should obligatory be an index.html file. This file will be opened while launching a landing page. The file can be index.php if there's a PHP feature for landing pages enabled in Keitaro settings.

Landing page requirements:

The paths in attributes src and href should be relevant. NOT CORRECT: <img src="/home.png" />. CORRECT: <img src="home.png" />.
There should not be any internal js-redirect, e.g. window.location = 'index.html'. (NOT CORRECT)
There should not be any internal js-scripts with anchors, e.g. smooth scroll won't work <a class="slow-scroll" href="#form2">order.

Additional requirements for landing pages on PHP:

There should not be any of the following functions header(), exec(), system(), ob_start(), eval() in the landing page code.
The loading of additional scripts in include() and require() should be on obsolete paths, e.g. require_once dirname(__FILE__) . ‘/lib.php’;.

A landing page can contain additional pages, but macros won’t work on them. All the parameters should be transferred manually:

<a href="page2.php?_offer={offer}&_subid={subid}">Page 2</a>

The content of parameters is also transfered manually:

<a href="<?php echo urlencode($_GET['_offer'])?>">Offer</a>
<form>
  <input type="hidden" name="subid" value="<?php echo urlencode($_GET['_subid'])?>">
</form>

If the PHP is enabled, global objects $rawClick and $stream can be used inside index.php:

<?php
echo $rawClick->getKeyword();
?>

# Preload

Lading pages of these type can be located on any server. Keitaro uploads this landing page and show its content to a visitor. If a landing page has any links to other pages, they will be opened with an original address.

# Redirect

If this kind of a landing page works, a user will be sent to its URL with a redirect. _subid and _token parameters will be automatically added to its address. These parameters are necessary for correct postbacks’ and offer links’ work.

# Landing Page - Action

If there's such a kind of a landing page in a stream, a definite action will be executed. E.g. if we choose «Show HTML», a visitor will see an HTML page.

# Enabling an offer on a landing page

It’s necessary to add a special piece of a code to every website link so that offer visits work. A stream with necessary offers should be enbled for an offer link to perform well. Below is a description of how to enable offers depending on a landing page type.

# Enabling offers on a local landing page with a preload

To create a link to an offer use a macros {offer}. An example of a button:

<a class="btn btn-success" href="{offer}">Link</a>

# Enabling more than one offer on a local landing page with a preload

If you have some offers you can define which offer to open:

<a class="btn btn-success" href="{offer:1}">Link</a>
<a class="btn btn-success" href="{offer:2}">Link</a>

1 and 2 — offers ID examples.

# Enabling an offer on a two pages local landing page

Suppose we have two pages - an index.html page and the page with an offer page2.php.

Update the links on an index.html page which lead to a page2.php, add the _token transfer tho that link:

<a href="page2.php?_token={token}">Link to Page2</a>

The link to an offer on a page2.php page should be added the following way:

<a href="//<?php echo $_SERVER['HTTP_HOST'] . '/?_lp=true&_token=' . urlencode($_GET['_token']) ?>">Offer</a>

For a multi offer landing page:

<a href="//<?php echo $_SERVER['HTTP_HOST'] . '/?_lp=true&_token=' . urlencode($_GET['_token']) ?>&offer_id=1">Offer 1</a>
<a href="//<?php echo $_SERVER['HTTP_HOST'] . '/?_lp=true&_token=' . urlencode($_GET['_token']) ?>&offer_id=2">Offer 2</a>
<a href="//<?php echo $_SERVER['HTTP_HOST'] . '/?_lp=true&_token=' . urlencode($_GET['_token']) ?>&offer_id=3">Offer 3</a>

# Enabling an offer on a landing page with a redirect

If you use a redirect, two obligatory parameters _token and _subid are added to a landing page address. To create a necessary offer link use a ready code from the right part of the screen, which you see while creating and editing a landing page.

# Enabling more than one offer on a landing page with a redirect

You need to add offer_id parameter to links. Example:

<a href="http://tracker.com/?_lp=true&_token=<?php echo urlencode($_GET['_token'])?>&offer_id=1">Offer link 1</a>
<a href="http://tracker.com/?_lp=true&_token=<?php echo urlencode($_GET['_token'])?>&offer_id=2">Offer link 2</a>

# Enabling an offer in Actions

{offer} macros can be used in Actions. E.g., if you use «Show HTML» action, you can insert an offer link inside the code.

# Using an order form on a landing page

If you send leads through a script, you need to send a click’s subid together with leads. Subid with {subid} macros can be added in local landing pages with a preload:

<input type="hidden" name="subid" value="{subid}" />

After, get the info in a parameter $_POST['subid'] (in case the form is transferred through the POST method).

# How to set up the form on a two pages local landing page

Assume we have two pages: an index page index.html (or index.php) and an order form page order.php.

Change the links on an index page adding: ?_subid={subid}: <a href="order.php?_subid={subid}">BUY</a>

In order.php form add to the very beginning:

session_start();
if (isset($_GET['_subid'])) {
    $_SESSION['_subid'] = $_GET['_subid'];
}

This code will accept _subid parameter and save it to the session. Now you can substitute this parameter from the session to the code to send data from the form, e.g.:

$params = array(
    'name'          => $post['name'],
    'phone'         => $post['phone'],
    'country'       => $post['country'],
    'sub1'            => $_SESSION['_subid'],        //       ←
);

# Enabling an external website with KClient PHP

This solution allows to get a traffic directly on a website and transfer data with KClient PHP to Keitaro.

An example of enabling a website with a ready-made library KClient PHP:

create a campaign;
create a landing page with your website address;
create a stream with «Landings and Offers» scheme. Choose a landing page(website) and offers;
go to «Integration» page (Additionally > Integration);
Choose “KClient PHP”;
add a code to your landing page following the manual.

# Adding offers to a website which works with KClient PHP

Delete $client->execute() line in a code. It calls an immediate redirect to an offer;
this kind of a code will give you a link to an offer: <a href="<?php echo $client->getOffer()?>">Offer Link</a>;
check if a landing page works.

# Enabling more than one offer on a website which works with KClient PHP

The situation is the same as with using an offer. All we need is to add an offer_id parameter:

<a href="<?php echo $client->getOffer(array('offer_id' => 1))?>">Offer link 1</a>
<a href="<?php echo $client->getOffer(array('offer_id' => 2))?>">Offer link 2</a>

# Enabling an external website with a tracking script

This solution is perfect for websites on a CMS. The code for installing a tracking script can be taken on a Campaign’s page in an Integration tab.

Read more about a tracking script on a tracking script page.

# Enabling an offer on a website which works with tracking script

Put a link with an {offer} macros in a website code, e.g.:

<a href="{offer}">Offer link</a>

All campaign streams should be with offers in order for link to work.

# Adding more than one offer to a website with a tracking script

Offers IDs can be added inside the links:

<a href="{offer}&offer_id=1">Offer link 1</a>
<a href="{offer}&offer_id=2">Offer link 2</a>

# Sending postbacks

The ways of sending postbacks depend on a type of a landing page being used.

# Sending postbacks from a local landing page (form)

If there’s a form on a landing page, an additional input is needed:

<form action="send.php" method="post">
<input type="hidden" name="subid" value="{subid}" />
</form>

Now postbacks can be sent in a send.php script:

$url = 'http://POSTBACK_URL?payout=100&status=sale&subid=' . urlencode($_POST['subid']);
file_get_contents($url);

# Sending postbacks from a local landing page (button)

If there’s just a button on a landing page subid is added the following way:

<a class="btn btn-success" href="thanks.php?subid={subid}">BUY</a>

Now postbacks can be sent in a thanks.php script:

$url = 'http://POSTBACK_URL?payout=100&status=sale&subid=' . urlencode($_GET['subid']);
file_get_contents($url);

# Updating parameters of a click from a landing page

Parameters can be updated in some ways:

in a postback, see page Receiving postbacks;
in an offer link, e.g., {offer}&sub_id_1=123;
through a special address update_tokens. See examples below.

# Updating parameters of a click on JS

<script type="text/javascript">
kUrl='http://keitaro_url/';
function update_tokens(subId, param, value) {
  var img = document.createElement("img");
  img.src= kUrl + '?_update_tokens=1&sub_id=' + subId + '&'+ param + '=' + value + '&return=img';
  img.height=0;
  img.width=0;
  document.getElementsByTagName("body")[0].appendChild(img);
}
</script>

Now you can all:

update_tokens('{subid}', 'sub_id_8', 'test')

# An example of update_tokens on PHP

session_start();
function updateParams($subId, $params) {
   $kUrl = 'TRACKER_URL';
   $url = $kUrl . '?_update_tokens=1&sub_id=' . urlencode($subId) . '&' . http_build_query($params);
   $result = file_get_contents($url);
   // echo $result;
}

Change TRACKER_URL to your tracker's address.

Now you can call updateParams('sub_id', [params]);. E.g.:

updateParams($_SESSION['sub_id'], array('sub_id_1' => 'info@gmail.com'))
