It contains some simple modifications extending the operation to include the UTW is_tag() function.
The changes made are not unique, as they are the same as have been described on a number of Non-english language blogs such as 082Net – a little hard to find if you don’t speak Korean, and as I have found in the past, if hacks are not provided as a distributable final version, very few people use them.
This plugin is intended to be used in advanced linking stuctures such as those described in WordPress SEO Masterclass For Competitive Niches
Rather than blocking duplicate content pages, they can be used to your advantage, but as customized landing pages and a method of channelling “Google Juice” away from pages that are receiving the majority of links, to pages that you wish to rank well, and also to your homepage to enhance monetization.
This plugin allows you to modify the default number of posts displayed by the WordPress loop before it creates a new page.
Not Just For SEO
There are all kinds of ways this plugin can also be used for aesthetic appeal and improved navigation.
It should be noted that this is a totally white-hat solution that even Googlers would approve of, as it is frequently recommended these days that sites should be developed to have a wider footprint rather than a deeper one.
It is one of the best solutions to minimise supplemental results on WordPress which are typically from a lack of PageRank, and not as many assume, duplicate content.
Full details and new permanent home for Custom Query String
A couple of additional notes in passing.
It is possible to use the original plugins (which was up to version 2.7) with UTW, but it involved jumping through a few unnecessary hoops which would decrease adoption and also prevent a number of useful linking structures.
This plugin was really in need of a home to ensure that people download a fully working version. Many links are broken to the original, and those that exist are to older versions.
As my readers appreciate, I just tinker with code, thus if extensive modifications are needed with the release of WP 2.3, I might need to strong-arm a friend into helping me manage the programming.
That being said, I am quite capable of supporting the plugin, and explain how it can be used in various ways, which is often more time consuming than the actual coding.
Whilst my advanced WordPress SEO tips might look a little daunting, Custom Query String is actually very simple to use.
Just install it as a regular plugin, go to Options >>> CQS and set up declarations for categories and tag pages, and date archives if you use them (most installations have them somewhere)
There are a few versions of CQS now available for WP2.3+ including Custom Query String Reloaded
I have some additional changes I still want to make with my own version
