Plugin Picks to Hit Core Web Vitals in 2025

Plugin Picks to Hit Core Web Vitals in 2025

---

The year 2025 has brought changes in how Google evaluates Core Web Vitals—and by choosing the right plugins, you can still deliver a top‑notch user experience that ranks well. From the switch from FID to INP (Interaction to Next Paint) in March 2025 to the stricter thresholds on CLS and LCP, performance attention matters more than ever

This guide walks through the Plugin Picks to Hit Core Web Vitals in 2025, accompanied by a step‑by‑step setup, and a FAQ to keep your implementation smooth. Whether you’re building a blog, an eCommerce store, or a marketing site, you’ll have a plugin stack that balances ease, power, and SEO‑friendliness.

🚀 Why Core Web Vitals Still Matter (and What Changed in 2025)

• LCP (Largest Contentful Paint): Should consistently stay under 2.5 s on mobile and desktop.

• CLS (Cumulative Layout Shift): Target less than 0.1 total shift.

• INP (Interaction to Next Paint): Replaced FID; good score is under 200 ms, focusing on real user interaction speed

With Google now requiring these metrics as a page experience ranking factor, it’s essential to grab every millisecond possible. Bloat, render‑blocking scripts, improperly handled images, and external tracking all drag your scores.

🎯 Step‑by‑Step Guide: Build a Plugin Stack That Hits Core Web Vitals

This checklist runs ~75% of the work and lets you stay nimble—especially when new Google updates or traffic surges arrive.

Step 1: Audit Your Baseline

Run Google PageSpeed Insights, Lighthouse, or the CrUX Dashboard to snapshot your current LCP, CLS, and INP on both mobile and desktop (affected by real-world field data). Note if FID is shown in former reports—switch to INP for accuracy

Save screenshots and export JSON “origin” or “URL” reports for before-and-after comparison.

Step 2: Pick Your Primary Caching Plugin

Your choice depends on your server stack:

• FlyingPress: Ideal on Apache or Nginx hosts (non-LiteSpeed). Frequently tops charts for real Core Web Vitals improvements, thanks to features like remove‑unused CSS, smart preload, lazy-bg helper, and Cloudflare‑Enterprise integration via FlyingCDN

• LiteSpeed Cache (LSCWP + QUIC.cloud): Free (even for large sites), packed with server‑side caching, LQIP image placeholders, object & browser caching, asset optimization, and advanced cache crawler options (e.g. Guest Mode) when hosted on LiteSpeed servers, making it fully capable of delivering CWV scores at no premium cost

• WP Rocket: Widely used and beginner‑friendly, offers minification, database cleanup, CDN integration (RocketCDN via BunnyCDN), lazy loading, and automatic delay JS. However, it lacks real-time remove‑unused CSS or font hosting—and its overhead is slightly heavier in empirical comparison to FlyingPress or LSCWP

Tip: Only install one major caching plugin to prevent conflicts. Use each plugin’s setup wizard or online guide (many “best settings for 2025” tutorials exist).

Step 3: Layer Perfmatters for Granular Control

Install Perfmatters (paid), especially if you’re using FlyingPress or LSCWP. While those handle page caching, Perfmatters allows you to selectively disable unwanted scripts, host Google Analytics and Fonts locally, easily implement critical‑asset preloading, and clean bloat code such as dashicons, XML‑RPC, or embeds—factors that impact CLS and INP the most

Key features to enable:

• Script Manager: Deactivate plugin/theme scripts on pages they’re not used.

• Remove unused CSS: Prefer “file mode” rather than inline for better stability.

• Preload: Preload hero images, fonts, CSS or JS critical files.

• Lazy load: Images, iframes, video, and background CSS.

• Local Analytics/Fonts: Charge local .js for GA and Google Font files.

If you chose WP Rocket, disable overlapping features within Perfmatters (e.g. lazy loading, CSS/JS minification). Similarly adjust if using FlyingPress or LSCWP

Step 4: Install an Image Optimization Plugin for WebP/AVIF Conversion

Even the best cache setup can’t optimize raw image formats. Use a plugin that compresses and serves modern image formats:

• ShortPixel Image Optimizer: Offers auto-conversion to WebP/AVIF, bulk compression, and thorough EXIF metadata removal.

• Imagify (by WP Rocket team): Compression levels (Normal, Aggressive, Ultra), clean UI, and easy WebP conversion.

• Smush: Lossless compression, on-upload optimization, lazy loading, WebP support included.

All these plugins help shrink image file sizes and reduce LCP—especially on mobile-heavy hero sections and galleries

Step 5: Set Up Proper Preloading, Deferring & DNS Hints

Your caching plugin and/or Perfmatters should let you:

• Defer most non-critical JS.

• Preload fonts and hero images above-the-fold.

• Add DNS-prefetch or preconnect for third-party domains like Google Analytics, ads, fonts, and CDNs.

This significantly improves speed metrics tied to LCP and INP.

Step 6: Use an Edge-Level Cache / CDN

Pick one of these options:

• Cloudflare APO and plugin: Caches HTML, reduces TTFB, often improves LCP (even in cold cache states) for ~US $5/month

• QUIC.cloud integration (if using LiteSpeed Cache): Delivers image optimization, page caching, and HTTP/3 edge preview.

• FlyingCDN with Cloudflare Enterprise: Included in FlyingPress & FlyingCDN subscription; handles priority routing and Mirage/Polish image optimization options onlinemediamasters.com.

Let your caching plugin purge cache when you update content, then flush your CDN cache too to ensure consistency.

Step 7: Test, Audit & Iterate

After implementation:

1. Run PageSpeed Insights again on the same URLs.

2. Compare LCP, CLS, INP vs baseline.

3. Check Chrome User Experience Report (CrUX) for field (real-user) score changes.

4. If INP is high, turn off JavaScript-heavy widgets or defer longer tasks using idle callbacks.

5. Watch CLS; ensure fixed width or dimensions for your hero hero images and video elements.

6. Review waterfall diagrams in Lighthouse or SpeedVitals to spot long render-blocking assets.

7. Revisit Perfmatters script manager periodically to adapt to new plugins.

🙋 Frequently Asked Questions

Q1: Do I need both a core cache plugin and Perfmatters?

Yes. Your caching plugin handles full-page and browser cache, while Perfmatters fine-tunes scripts, loading order, and eliminates bloat. Together, they reduce both TTFB and main-thread blocking for best LCP and INP scores

Q2: My host doesn’t support LiteSpeed. Is that okay?

Absolutely—FlyingPress is excellent with Apache/Nginx, and WP Rocket also does fine. Just avoid installing LiteSpeed Cache in a non-LiteSpeed environment (it may not work or can cause issues).

Q3: How many plugins is too many?

We aim for 3–5: a cache plugin (one of the majors), Perfmatters for tweaks, an image optimizer, and optionally the CDN plugin. Avoid overlap; e.g. disable lazy load in Perfmatters if your cache plugin already handles it.

Q4: What scores should I expect now?

Good targets:

• LCP < 2.5 s on mobile and desktop (ideally < 1.8s)

• CLS < 0.1 on both

• INP < 200 ms (formerly FID)

Benchmark at least 90 mobile / 95 desktop in current PageSpeed nouns.

Q5: Can these plugins break my site?

Rare but possible—especially with “remove unused CSS” or deferring JS. Always thoroughly test after enabling any aggressive feature; check front-end UI and checkout/cart forms on e-commerce sites.

Q6: How often should I monitor?

Check after any major design or content launch, monthly, and right after plugin or theme updates. Performance drift is common over time.
