# Canonical Chaos, Round Three: Polishing the Blade ![Canonical Chaos, Round Three: Polishing the Blade](https://cdn.richeyweb.com/images/articles/joomlas-canonical-url-chaos/canonical-banana.webp) I’ve been carving through Joomla’s [canonical URL](/blog/hosting/negative-seo-via-url-parameter-abuse-in-joomla "Negative SEO via URL Parameter Abuse in Joomla") chaos because I can’t let good sites—mine included—drown in [duplicate URLs](/blog/development/joomlas-canonical-url-chaos "Joomla’s Canonical URL Chaos"), poisoned [SERPs](/blog/hosting/unavailable-after-white-hat-seo-hack-might-be-paying-off "unavailable_after White-Hat SEO Hack Might Be Paying Off"), or half-hearted fixes that fumble query strings or demand cash. Round one was the rally cry, round two saw com\_tags IDs tamed and 99% of Joomla’s core locked down—com\_contact, com\_content, com\_finder, [com\_newsfeeds](/joomla-techniques/youtube-rss-feed-gallery "YouTube RSS Feed Gallery"), com\_users, com\_weblinks, even com\_k2. Now, as of April 1, 2025, I’ve spotted and slain another pest: start=0 parameters. My canonical [URL](/blog/development/canonical-chaos-round-four-victory-in-sight "Canonical Chaos, Round Four: Victory in Sight") plugin’s nearly release-ready, and I’m not stopping until it’s flawless. ## Start=0, Stop Duplicates Here’s the dirt: Joomla’s fine with URLs like mysite.com/articles?start=0—it’s valid, sure, but it’s the same damn page as mysite.com/articles without the parameter. start=0 just means “begin at the beginning,” which is the default—no need for the baggage. Left alone, those duplicates clog [Google](/blog/development/generator-tag-claim-your-joomla-sites "Generator Tag: Claim Your Joomla Sites") Search Console, split your [SEO](/test-article "Shader BG Test") juice, and invite confusion. I’ve tuned the [plugin](/blog/development/bug-reports-a-developers-best-friend-not-a-burden "Bug Reports: A Developer's Best Friend, Not a Burden") to sniff these out and strip them, forcing the clean, no-parameter URL as the canonical. It’s running live on my sites, and it’s tight—com\_content lists, com\_tags pages, you name it. This isn’t a tweak; it’s a purge, and it’s pushing me closer to a rock-solid release. ## Poison-Proof and Battle-Tested SERP poisoning—where some fool’s ?junkparameter twists a good URL into trash—keeps getting smoked. With start=0 gone, alongside fixes like /tags/3 to /tags/joomla, this plugin’s a [fortress](/blog/hosting/microsoft-deliverability-sendgrid-and-blacklists "Microsoft Deliverability - SendGrid and Blacklists") across Joomla’s core and beyond. Live tests on my sites prove it: com\_finder results, com\_users profiles, com\_newsfeeds feeds—all stay clean, [no duplicates](/joomla-techniques/how-to-add-custom-scripts-or-stylesheets-to-a-single-joomla-article-without-losing-your-mind "Add Custom Scripts or Stylesheets to a Joomla Article") sneaking through. That 1% gap from last time? It’s shrinking fast. Edge cases like this are the last holdouts, and I’m hunting them down to make this thing bulletproof for release. ## Free, Fierce, Almost There Still [free](/blog/development/new-geoip-coming-soon "New GeoIP Coming Soon"), still no gatekeepers—SEO shouldn’t come with a toll booth. At 99-point-something percent, it’s covering every core component I’ve thrown at it, plus com\_k2, and now it’s shedding junk like start=0. It’s open too—drop in a fixer class, and you’re in the fight. I’m honing this for release because [Joomla](/blog/hosting/cron-vs-joomla-lazy-scheduler-and-webcron "Cron vs Joomla Lazy Scheduler and WebCron") deserves a [canonical URL plugin](/blog/development/another-canonical-url-demon-slain "Another Canonical URL Demon Slain") that’s not just good, but done—no half-measures, no loose ends. Live testing’s my crucible; every tweak like this makes it sharper, readier for the world. I can't take a chance that Google isn't happy, because what's the point if it isn't? Besides, it's already spitting out better canonicals than any other plugin I've tested. LFG! ## The Finish Line Beckons Release is close—I can taste it. That start=0 fix is one of the final polish strokes, turning a 99% beast into a 100% blade. Next? Maybe third-party turf like VirtueMart if the community bites, but first, I’m locking this down for Joomla’s core. This is my Bad Wolf rewrite: duplicate chaos—start=0 or otherwise—dies, URLs shine, SERPs stay pure. I’m fighting for a Joomla where [site owners](/blog/development/problems-turn-into-features "Problems Turn Into Features") don’t sweat Search Console warnings. Round three’s mine, and the war’s about to end—for me, for you, for good. - [ email ](mailto:?subject=Canonical+Chaos%2C+Round+Three%3A+Polishing+the+Blade&body=https%3A%2F%2Fwww.richeyweb.com%2Fblog%2Fdevelopment%2Fcanonical-chaos-round-three-polishing-the-blade) - [ facebook ](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.richeyweb.com%2Fblog%2Fdevelopment%2Fcanonical-chaos-round-three-polishing-the-blade) - [ x-twitter ](https://twitter.com/intent/tweet?text=Canonical+Chaos%2C+Round+Three%3A+Polishing+the+Blade%3A+https%3A%2F%2Fwww.richeyweb.com%2Fblog%2Fdevelopment%2Fcanonical-chaos-round-three-polishing-the-blade) - [ linkedin ](http://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fwww.richeyweb.com%2Fblog%2Fdevelopment%2Fcanonical-chaos-round-three-polishing-the-blade&title=Canonical+Chaos%2C+Round+Three%3A+Polishing+the+Blade&summary=I%E2%80%99ve+been+carving+through+Joomla%E2%80%99s+canonical+URL+c...) - [ pinterest ](http://pinterest.com/pin/create/button/?url=https%3A%2F%2Fwww.richeyweb.com%2Fblog%2Fdevelopment%2Fcanonical-chaos-round-three-polishing-the-blade&media=https%3A%2F%2Fcdn.joomla.org%2Fimages%2Fjoomla-org-og.jpg&description=Canonical+Chaos%2C+Round+Three%3A+Polishing+the+Blade) [ Previous article: Canonical Chaos, Round Four: Victory in Sight Canonical Chaos, Round Four: Victory in Sight ](/blog/development/canonical-chaos-round-four-victory-in-sight) [ Next article: Another Canonical URL Demon Slain Another Canonical URL Demon Slain ](/blog/development/another-canonical-url-demon-slain) ##### We Value Your Privacy We use cookies to enhance your experience and for traffic analysis.
