URL & IP Canonicalization Testing

Shown below are a set of URL and IP address canonical testing tools. These tools can be used to check whether or not a web page has proper canonical tags. You will also be able to determine which page or pages should be indexed by search engines based on their canonical location.

What is URL and IP address canonicalization?

Canonicalization is the process of selecting the best URL of a webpage when there are several choices. This processes usually refers to home pages. For example, most people would consider these the same URLs:

  • www.example.com
  • example.com/
  • www.example.com/index.html
  • example.com/home.asp

But technically all of these URLs are different. Google search engine algorithms and a web server will most likely present completely different content for all the URLs above. When there are URL canonicalization and IP address conflicts, search engines may be unsure about which URL is the correct one to index.

W3C Validation Testing

Advanced Code Testing & Analysis

Flash, javascript, frames, dynamic URL’s and other SEO challenges are addressed before work commences. As a programmer, your text editor is your toolbox and every feature is a different tool. Using a barebones editor (e.g. Notepad) to write code is like building a house with only a hammer: it’s possible, but way more trouble than it’s worth, and the end result won’t be very good.

JavaScript is a messy language to begin with, so you’ll need all the help you can get. A proper, well-equipped text editor can help you code faster, write cleaner code, catch bugs sooner rather than later, but most of all, make programming fun and enjoyable.

Here is a list of must-have tools.


Firebug is a full-featured debugger and editor that allows you to work with a page’s HTML, JavaScript, CSS, DOM and more. You can also use the extension to monitor JavaScript, CSS, and XML in real time, look for errors that may be occurring in them, and learn what you need to do to repair them.

An essential tool in just about every designer’s arsenal of tools, Firebug has become so commonplace that it has even begun getting its own extensions (such as SitePoint’s own CodeBurner reference tool).

Keyword Density Testing

Keyword Density is known as the number of times a keyword or phrase used in a page relative to the total number of words present.

 Keyword Density = # of keywords / # of total words

There are plenty of keyword density calculator tools available.
