Keeping track of your access and error logs is a critical component of any serious security strategy. Many times, you will see a recorded entry that looks legitimate, such that it may easily be dismissed as genuine Google fare, only to discover upon closer investigation a fraudulent agent. There are many such cloaked or disguised agents crawling around these days, mimicking various search engines to hide beneath the radar. So it’s always a good idea to implement a procedure for […] Continue reading »
In the hellish battle against spam, many WordPress users have adopted a highly effective trinity of anti-spam plugins: Akismet Bad Behavior Spam Karma This effective triage of free WordPress plugins has served many a WP-blogger well, eliminating virtually 99% of all automated comment-related spam. When spam first became a problem for me, I installed this triple-threat arsenal of anti-spam plugins and immediately enjoyed the results. Although Spam Karma seemed a little invasive and resource-intensive, too much protection seemed far better […] Continue reading »

After switching Perishable Press to its current home at A Small Orange, I began noticing an unusual problem with referrer data displayed in Mint. Specifically, the first item recorded in the XXX Strong Mint data panel — for both “Most Recent” and “Repeat” views — displayed several thousand hits for various site resources, all reporting the following IP address: Continue reading »
WordPress users employing permalinks via htaccess to optimize their dynamic URLs transform complicated-looking links such as: http://example.com/blog/index.php?page=33 ..into search-engine friendly links such as: http://example.com/blog/post-title/ Every rewritten URL relies on a common set of htaccess rules to transform the links. The htaccess rules for all WordPress permalinks look like this for root WP installations: Continue reading »
![[ Image: Death-metal rocker drunk with power ]](https://perishablepress.com/wp/wp-content/images/2007/misc-chunks/ultimate-nofollow-blacklist.jpg "Behold the power of ultimate blacklist!")
Several days ago, I posted an article explaining how to hack your own WordPress nofollow blacklist. Immediately thereafter, I published an elaborate article focusing on automatic methods of nofollow blacklisting via WordPress plugins. In this article, I expand on the original blacklist hack by incorporating functional differentiation between commentator links, trackbacks, and pingbacks. If anything, think of this as an exercise in hacking WordPress, rewarding in and of itself, if not otherwise entirely impractical. Of course, whenever possible, you should […] Continue reading »
![[ Image: Inverted Eye Detail ]](https://perishablepress.com/wp/wp-content/images/2007/misc-chunks/dofollow-whitelist.jpg)
Before repenting of my filthy “nofollow” addiction, I experimented briefly with a “dofollow whitelist” for commentator URL links. The idea behind the whitelist is to reward frequent commentators, feed subscribers, site patrons, and other guests by selectively removing the automatically generated nofollow attributes from their associated comment-author links. For nofollow enthusiasts, a dofollow whitelist is a great way to show appreciation for people who support your blogging efforts. Now, before we go hacking away at WordPress, keep in mind that […] Continue reading »
Is that spam or are you just trying to comment? Removing nofollow attributes from your WordPress-powered site is a great way to encourage comments and attract visitors. Many commentators will leave useful, constructive feedback, but there will always be a few losers who would attempt to game your generous link love. Fortunately, identifying these mindless link whores is relatively easy. Here are a few priceless examples of actual spam (i.e., linked) comments left here at Perishable Press (links removed for […] Continue reading »

Previously, in our unofficial “WordPress dofollow upgrade” series, we dished several techniques for removing the antisocial nofollow attributes from default installations of WordPress. After an exhaustive review of available dofollow plugins, we explained how drop-dead easy it is to transform any WordPress blog into a well-standing member of the dofollow community without relying on a plugin to do the job. Our next article detailed a nofollow removal hack that selectively targets pingbacks, trackbacks, and commentator links. Then, we went off […] Continue reading »
Encourage Comments by Completely Eliminating All Nofollow Links! Want to remove all traces of the hideous nofollow attribute without having to install yet another unnecessary plugin? By default, WordPress generates nofollow links in three different ways — this article will show you how to eliminate all of them.. Continue reading »
After our previous article, we all know how easy it is to kill the default nofollow attributes that WordPress automatically injects into all commentator, trackback, and pingback links. Indeed, our original one-minute upgrade delivers dofollow links across the board, effectively passing the love juice to every type of response. Fine for some, but some need more.. In this article, we improve the original dofollow upgrade by differentiating between the three different response types. With our “deluxe” model, nofollow attributes may […] Continue reading »

This article explains how to eliminate nofollow tags from all trackback, pingback, and commentator links in less than one minute.. After finally repenting of my nofollow sins, I began looking for the best way to eliminate the nofollow attributes that WordPress automatically injects into all commentator URL links. Of course, the most popular technique for removing nofollow attributes from comment links involves one […] Continue reading »
During the most recent Perishable Press redesign, I noticed that several of my WordPress admin pages had been assigned significant levels of PageRank. Not good. After some investigation, I realized that my ancient robots.txt rules were insufficient in preventing Google from indexing various WordPress admin pages. Specifically, the following pages have been indexed and subsequently assigned PageRank: Continue reading »
Recently, I discussed the suspicious behavior recently observed by the Yahoo! Slurp crawler. As revealed by the site’s closely watched 404-error logs, Yahoo! had been requesting a series of nonexistent resources. Although a majority of the 404 errors were exclusive to the Slurp crawler, there were several instances of requests that were also coming from Google, Live, and even Ask. Initially, these distinct errors were misdiagnosed as existing URLs appended with various JavaScript functions. Here are a few typical examples […] Continue reading »

Readers occasionally ask for help with their WordPress loops. Usually, these requests involve modifying the loop with some customized functionality. Frequently, such customization involves one of these popular behaviors: Continue reading »
![[ Image: Abstract Mathematical Diagram ]](https://perishablepress.com/wp/wp-content/images/2009/misc-chunks/temp-redirect.jpg)
In our article Stupid htaccess Tricks, we present the htaccess code required for redirecting visitors temporarily during periods of site maintenance. Although the article provides everything needed to implement the temporary redirect, I think readers would benefit from a more thorough examination of the process — nothing too serious, just enough to get it right. After discussing temporary redirects via htaccess, I’ll also explain how to accomplish the same thing using only a small slice of PHP. It’s like two […] Continue reading »
Recently, I needed to find and replace all instances of “http://website” in the wp_comments table of the WordPress database. Fortunately, SQL provides a simple way to find and replace data with its wonderful UPDATE function. Continue reading »
