Final Project Source Code and Testing - PHP

You can download the final source code as discussed in this tutorial. 

You need to do the following before you can fully implement the script for your own personal use:

• Get a Recaptcha public key and private key. You can get these at http://www.google.com/recaptcha
  
• Get a Yahoo Links API Application ID. The procedure was already discussed in the previous tutorials.
  
• Change the include path of the stop words (refer to the above script).
  
• If you wish, you can even add more stop words or any words that you do not want to be part of the keyword title list. You can simply edit the stopwordslist.php file to add more array elements.

Here is a screen shot of the web application before any data processing:

Below is an example using this tool.

The live version of the tool is here: http://www.php-developer.org/backlinkcount/checkyourlinkpopularity.php

Suppose you are interested in getting all the backlinks pointing to all of the pages of http://www.devshed.com, not just the home page.

So you need to enter http://www.devshed.com under “Enter root domain URL." Do not place the trailing slash “/” at the end of the website's URL.

Since you are interested in getting all of the backlinks pointing to all of the pages, select the option “Entire website.”

Enter the captcha at the form and click “Submit.” Wait for at most two minutes.

The first thing you should  see is this line:
ESTIMATED TOTAL BACKLINKS FROM UNIQUE DOMAINS POINTING TO ENTIRE SITE: 285006

This means that 285006 backlinks are from unique domains, but these domains NOT still checked if they belong to a unique Class C IP address.

The second bolded summary is this: ESTIMATED TOTAL BACKLINKS FROM UNIQUE DOMAINS IN UNIQUE CLASS IP POINTING TO ENTIRE SITE: 157044

So 157044 is an estimate of all domains linking to the pages of  www.devshed.com and coming from unique class C IP addresses.

Finally, one of the most important results is the “Link Relevance Report.”

The screen shot of the report above tells us that the pages linking back to  www.devshed.com pages have a high percentage of “search,” “tools,” “fedora,” “seo” and “linux” used in their title tags, which are also related to the topics discussed on Dev Shed.
