HomePHP Page 3 - Determine Link Relevance and Unique Class C IP using Yahoo Links API
Final Project Source Code and Testing - PHP
The Yahoo Site Explorer Inbound Links API comes in handy for a variety of purposes. You can get all sorts of data from it using PHP, from counting your backlinks to analyzing where they're coming from. This article will show you how to build a backlink checker tool that can do this and more.
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.
