Using Web Bots to hunt for B2B marketing leads

How we got vendor email addresses

Lets use houzz.com (educational purposes)  as our target for this example, goal is to obtain email addresses from the sites online vendors directory. 

Problem is the email addresses ARE NOT available on HOUZZ's website. 

We'll walk you through how we overcame this problem and got what we needed. 

The Houzz BOT at work....Console reporting back results

analysis of site and strategy used

Houzz vendor listings

targets indexed

So we use this page to index all the vendors aka our targets.

Vendor Detail Page

Email Workaround

We then use our bot to visit each vendors page, and collect any relative vendors details. Unfortunately no email address is listed. but. they do provide the vendors website, so we'll send our bot there next

Vendors Website

Obtain Payload

Our bot is now on the vendors website, we instruct it to scour the sites pages in search for email address (aka payload) 

Here is the code which you can access bitbucket repository

The MySQL code is commented out, in case youd rather store the data retrieved in a database. I opted to place results in a CSV file.

The script write 2 CSV files, one for indexing website URLs in step 1.

In step 2 we call the CSV file of target of vendor website URLs to search for the email addresses

Feedback is outputted in the terminal using fwrite(STDOUT)

//You can get these files over at my https:\/\/internettechnologyservices.com//internettechnologyservices.com//bitbucket.org/nicknguyenzrd/houzzbot/

error_reporting(E_ERROR | E_PARSE);
//@ini_set('display_errors', 0);

/* Uncomment below to store data in MYSQL
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "invoice";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
	die("Connection failed: " . $conn->connect_error);

//Step 1 Gather  Houzz Links

//Open Links File cause thats where well dump our data payload
$handle = fopen("links.txt", "r");
//Data Placeholder Array

//Deal with multiple page results with The All Powerful Iterative Loop 
for ($i = 1; $i <= 30; $i++) { $doc = new DOMDocument(); if($i===1) {$p=0; //To grab the first page had a different URL $doc->loadHTML( file_get_contents( "http://www.houzz.com/professionals/landscape-architect/orange-county"));
//Every Page after the first page "/p/{page number}"
	$doc->loadHTML( file_get_contents( "http://www.houzz.com/professionals/landscape-architect/orange-county/p/" . $p ) );

			$somecontent = $a->attributes->getNamedItem( 'href' )->value."\r\n";
			fwrite(STDOUT, $somecontent);

	//var_dump( $data );

//Step 2 Gather company details (Houzz doesnt list email addresses), so well have to improvise and go to there website to acquire target email contact if its listed on there website. 

//Make sure we double check were dealing with valid URLS cause that can really fuck things up once this bitch is fired up!
