Permalinks Migration Plugin for wordpress

With this plugin, you can safely change your permalink structure without breaking the old links to your website,and even doesn’t affect your search engine rankings.

introduction

Many people want to change their permalink structure,for example, from /%year%/%monthnum%/%day%/%postname%/ to /%category%/%postname%/

But doing so will make all pages indexed by search engines become invalid,moreover, losing visitors from other sites or bookmarks that links to you.

There is a way to tell the search engines (and browsers) that the page has permenantly moved, and that the old address should be replaced by the new one . It’s called a “301 Redirect”, also known as a Permanent Redirect.When you do this, Search engines will update their indexes quickly and you won’t lose your pagerank.you will continue to receive traffic as though nothing had changed. This works for search engines, bookmarks, and links from other sites.

By now, you know how can you change your permalinks without losing the traffic you’re already getting. You can download this Permalink Migration Plugin to achieve this for you.

This plugin will generates a “301 Redirect” when user or spider visit your site through old permalinks,and redirect them to the new permalinks of the same post.

Do not fear to change your permalink structure now, you would never lose any visitors due to changed addresses.

Download Dean’s Permalinks Migration Plugin Version 1.0

Installation

  1. unzip and upload the file into your wp-content/plugins/ directory.
  2. Activate it on your Admin Panel->Plugin Management page.

Usage

  1. goto admin panel->options->PermalinksMigration.set the old permanlink structure of your site.
  2. goto admin panel->options->Permalinks.change the new permalink structure to what you want. (personally I recommend /%category%/%postname%/, you can read @ArunBasilLal’s tour  to learn more about how to Optimizing Permalinks for Better SEO)

YAAPC has upgraded to version 1.1.3 with SEO Enhanced

This version adds a feature that can automatically generate “noindex,follow” meta tag in your paged comments page to avoid duplicate content in search engine.Many thanks to Hank’s for his great comment and advice to YAAPC:

Isn’t that causeing a lot of duplicate content? Do i’ve to stop all “?p=x&cp=x#comments” pages from being indexed via .htaccess/robot.txt or is there a switch to mark them “noindex” in robots meta tag? Every click on another comments page is counted as real pageview, right?

Boost your WordPress performance on Windows IIS 6 with FastCGI and eAccelerator in 5 minutes

First,download and install the FastCgi Extension for IIS 6 from microsoft.The FastCGI protocol enables PHP applications to be hosted on the IIS web server in a high-performance and reliable way.FastCGI re-uses CGI processes for multiple requests, which provides a significant performance boost as compared to CGI.

Once FastCgi is installed,Config FastCGI extension to work with php:

  1. Open a command line window,and change the current directory  to %WINDIR%\system32\inetsrv.
  2. Run
    cscript fcgiconfig.js -add -section:"PHP" -extension:php -path:"C:\PHP\php-cgi.exe"
    to register the PHP CGI program as the one that will be processing .php extensions.
  3. Modify fcigext.ini file in %WINDIR%\system32\inetsrv as the following (assuming you installed PHP to C:\PHP folder):

    [Types]
    php=PHP

    [PHP]
    ExePath=c:\php\php-cgi.exe

Next,download and install eAccelerator.eAccelerator is a free open-source PHP accelerator, optimizer, and dynamic content cache. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.

After eAccelerator is downloaded:

  1. Copy eaccelerator.dll to your php extensions folder to c:\php\extensions.(assuming you installed PHP to C:\PHP folder)
  2. Create a folder (with the appropriate permissions) for the temporary cached files.
    For example: c:\tmp\eaccelerator
  3. Add the following to your php.ini (as the first loaded extension):

    extension=eAccelerator.dll
    eaccelerator.shm_size="128"
    eaccelerator.cache_dir="c:\tmp\eaccelerator"
    eaccelerator.enable="1"
    eaccelerator.optimizer="1"
    eaccelerator.check_mtime="1"
    eaccelerator.filter=""
    eaccelerator.shm_max="0"
    eaccelerator.shm_ttl="0"
    eaccelerator.shm_prune_period="0" 
    eaccelerator.shm_only="0"
    eaccelerator.compress="1"
    eaccelerator.compress_level="9"
    eaccelerator.keys = "shm"
    eaccelerator.sessions = "shm"
    eaccelerator.content = "shm"

That’s all,restart your IIS and you’ll get a faster WordPress on windows IIS 6 with highly boosted performance.

Because IIS does not support mod_rewrite module for rewriting URLs,the biggest problem hosting wordpress on iis is that you always get an ‘ugly’ and not SEO-friendly index.php in your permalinks.you can install wp_url_rewriting,an open source URL rewriting for wordpress, to resolve this issue.

FAQ (from http://code.google.com/p/google-code-prettify/)

  1. Which languages does it work for?
    The comments in prettify.js are authoritative but the lexer should work on a number of languages including C and friends, Java, Python, Bash, SQL, HTML, XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk and a decent subset of Perl, but, because of commenting conventions, doesn’t work on Smalltalk, Lisp-like, or CAML-like languages.
  2. How do I specify which language my code is in?
    There’s no way to tell it which language because would complicate the interface. If it doesn’t guess the language properly, that’s a bug.
  3. Which browsers does it work with?
    It’s been tested with IE 6, Firefox 1.5 & 2, and Safari 2.0.4. Look at the test page to see if it works in your browser.

wp_url_rewriting:URL Rewriting for WordPress under IIS (V 2.1)

This ISAPI filter removes the index.php from WordPress permalinks on Windows IIS,making your permalinks more pretty and SEO friendly.

Because IIS does not support mod_rewrite module for rewriting URLs, if you are running WordPress on Windows IIS,whenever you try to use Permalinks, you always get something like this:

2). after register,Login to your WordPress admin panel->options->Permalinks,make sure you have removed the index.php from your permalink structure.

3). Do a little hack to WordPress file ‘link-template.php’ to make paging works well for categories:(NOTE: You don’t need to do this step if you are using WordPress 2.3.0 or newer)

open file /wp-includes/link-template.php and find the following code:

function get_pagenum_link($pagenum = 1) {

 $qstr = $_SERVER['REQUEST_URI'];

 $page_querystring = "paged";

 ...
