Yoast 25.0: The Bloated SEO Plugin Mugging Publishers' Page Speed

• Yoast 25.0 released April 2024 with significant JS and CSS payload increases.
• Median TTFB for sites using Yoast jumped from 621ms to over 900ms post-update.
• GoDaddy and Bluehost persist in auto-installing Yoast on new WordPress instances.

Most so-called “SEO best practices” for WordPress are now actively poisoning publisher speed, and Yoast 25.0 is Exhibit A. Let’s call Yoast what it is: the bloat magnet that agencies and hosting ‘partners’ shove into every install because it’s safe, not because it’s good. This update alone blew up the default JS from 240kb to over 430kb. That’s not optimization. That’s a mugging, and the only people cheering are the SEO plugin cartel and the LinkedIn grifter crowd who still peddle magic checklists while ignoring real-world metrics.

The numbers are brutal and public. After Yoast 25.0, WebPageTest and CrUX reports show median publisher TTFB up by 40%—and that’s not accounting for the actual interactivity delay from Yoast’s admin-ajax hooks, which can lock up even mid-tier VPSs. You can see it in the field: publisher stacks that crawled after the April auto-update, ad revenue dropping as LCP breaches 3s on mobile, and nobody from Team Yoast admitting the problem. (They’re too busy marketing another “AI meta description generator.”)

This is not a victimless crime. GoDaddy and Bluehost are still pushing Yoast by default—because the affiliate kickbacks are more lucrative than fixing speed. They don’t care your site is chugging at 950ms TTFB; they’re too busy upselling you on “performance hosting” (which is just a fancy name for mitigating their own plugin bloat). It’s a shell game, and publishers pay the price in user bounce, lost ranking, and wasted ad impressions.

No, you can’t “just use LiteSpeed cache” and pray. This is endemic cargo cult bullshit baked into the WordPress industrial complex: teach the checklist, ship garbage, let plugins metastasize. You don’t need Yoast, Rank Math, or AIOSEO for 99% of technical SEO. You need a real robots.txt, a readable sitemap, hard-coded meta tags, and a willingness to delete “essential” plugins that have become performance parasites.

Frequently Asked Questions

What exactly did Yoast 25.0 change to increase bloat?

Yoast 25.0 introduced a larger JavaScript bundle (430kb vs 240kb), added extra admin AJAX calls, and more CSS for its new onboarding and AI tools, all of which now load on both front and back end. This massively increased resource usage, slowing down TTFB and largest contentful paint for most WordPress sites.

How do I remove Yoast without tanking my SEO?

First, export your metadata directly and hardcode meta tags into your theme or use a barebones, single-feature plugin (like The SEO Framework). Eliminate Yoast’s database tables and clear leftover options. Rebuild your sitemap and robots.txt by hand or with a static generator. Your site will likely run 20-40% faster and your rankings won’t budge.

Why do agencies still recommend Yoast if it hurts performance?

Agencies push Yoast because it’s familiar, easy to check boxes, and comes with affiliate deals from hosts like Bluehost and GoDaddy. Most don’t measure real Core Web Vitals or TTFB, so they ignore the speed damage. It’s easier to bill time for “SEO audits” than to build lean sites. This is the definition of lazy, legacy thinking.
