Canonical URLs and Subdomains with Plesk
I am in the process of migrating my sites from A Small Orange to Media Temple. Part of that process involves canonicalizing domain URLs to help maximize SEO strategy. At ASO, URL canonicalization required just a few htaccess directives: # enforce no www prefix <ifmodule mod_rewrite.c> RewriteCond %{HTTP_HOST} !^domain\.tld$ [NC] RewriteRule ^(.*)$ http://domain.tld/$1 [R=301,L] </ifmodule> When placed in the web-accessible root directory’s htaccess file, that snippet will ensure that all requests for your site are not prefixed with www. There’s […] Continue reading »

I’ve had much success with this new firewall, but more testing is needed to ensure maximum compatibility and minimal issues. Continue reading »
HTAccess Spring Cleaning 2009
Just like last year, this Spring I have been taking some time to do some general maintenance here at Perishable Press. This includes everything from fixing broken links and resolving errors to optimizing scripts and eliminating unnecessary plugins. I’ll admit, this type of work is often quite dull, however I always enjoy the process of cleaning up my HTAccess files. In this post, I share some of the changes made to my HTAccess files and explain the reasoning behind each […] Continue reading »
Dynamic Link Insertion via Unobtrusive External JavaScript
In my recent guest post at The Nexus, I discuss Google’s new nofollow policy and suggest several ways to deal with it. In that article, I explain how Google allegedly has changed the way it deals with nofollow links. Instead of transferring leftover nofollow juice to remaining dofollow links as they always have, Google now pours all that wonderful nofollow juice right down the drain. This shift in policy comes as a terrible surprise to many webmasters and SEO gurus, […] Continue reading »

Unexplained Crawl Behavior Involving Tagged Query Strings
I need your help! I am losing my mind trying to solve another baffling mystery. For the past three or four months, I have been recording many 404 Errors generated from msnbot, Yahoo-Slurp, and other spider crawls. These errors result from invalid requests for URLs containing query strings such as the following: https://example.com/press/page/2/?tag=spam https://example.com/press/page/3/?tag=code https://example.com/press/page/2/?tag=email https://example.com/press/page/2/?tag=xhtml https://example.com/press/page/4/?tag=notes https://example.com/press/page/2/?tag=flash https://example.com/press/page/2/?tag=links https://example.com/press/page/3/?tag=theme https://example.com/press/page/2/?tag=press Note: For these example URLs, I replaced my domain, perishablepress.com with the generic example.com. Turns out that listing the plain-text […] Continue reading »
PHP and JavaScript Fallbacks for Your Public Feedburner Count
With the recent Feedburner service outage, many sites across the Web experienced severe drops in their Feedburner subscriber counts. Apparently, Google is requiring all Feedburner accounts to be transferred over to Google by the end of February. In the midst of this mass migration, chaotic subscriber data has been reported to include everything from dramatic count drops and fluctuating reach statistics to zero-count values and dreaded “N/A” subscriber-count errors. Obviously, displaying erroneous subscriber-count data on your site is not a […] Continue reading »
Stupid Twitter Tricks
Might as well face it, Twitter is here to stay. Not that it’s all that bad, just used to be a lot more laid-back and enjoyable. These days it seems to have been taken over by the lowest common-denominator, mostly high-school twits or useless commercial propaganda. Even so, I still enjoy tweeting the occasional profound thought once in awhile, and even like to play around with various types of “advanced” Twitter functionality. You know, cool stuff like including “Tweet This!” links […] Continue reading »
Redirect All (Broken) Links from any Domain via HTAccess
Here’s the scene: you have been noticing a large number of 404 requests coming from a particular domain. You check it out and realize that the domain in question has a number of misdirected links to your site. The links may resemble legitimate URLs, but because of typographical errors, markup errors, or outdated references, they are broken, leading to nowhere on your site and producing a nice 404 error for every request. Ugh. Or, another painful scenario would be a […] Continue reading »

Add RSS Feed Link Icons to WordPress Category Listings
This brief tutorial explains two methods for adding RSS feed link icons to category listings. Let’s say that you have a list of category links, where each link targets a specific category view. Now let’s say that, next to each category link, you would like to provide a icon that links to that particular category’s syndicated feed. So, rather than cluttering up your page with two sets of category links — one for category views and another for category feeds […] Continue reading »
Redirect WordPress Feeds to Feedburner via htaccess (Redux)
In a previous article, I explain how to redirect your WordPress feeds to Feedburner. Redirecting your WordPress feeds to Feedburner enables you to take advantage of their many freely provided, highly useful tracking and statistical services. Although there are a few important things to consider before optimizing your feeds and switching to Feedburner, many WordPress users redirect their blog’s two main feeds — “main content” and “all comments” — using either a plugin or directly via htaccess. Here is the […] Continue reading »
WordPress Discussion Management: Enable or Disable Comments and Pingbacks via SQL
Continuing my quest to stop comment spam without using plugins, I have decided to disable comments on “old” posts. In my experience, over 90% of comment, trackback and pingback spam occurs on posts that have been online for over a month or so, just long enough to be indexed by the search engines and picked up by spammers. Especially for older posts that have managed to acquire a little page rank, the frequency of spam attempts is far greater than […] Continue reading »
