Core Web Vitals fixes for LCP, INP and CLS.
Core Web Vitals measure how fast the main content appears (LCP), how quickly the page responds to input (INP) and how much the layout jumps (CLS). We start from real-user data, find the specific element or script responsible and fix that, rather than chasing a lab score.
When You Need This
The situations where this work pays for itself.
Signs it is time
- Search Console shows URLs flagged as Poor or Needs improvement
- Your site feels slow on phones even if it seems fine on your laptop
- Banners, ads or images push content around while the page loads
- Buttons and menus lag after a tap
- A redesign or new plugins made the site slower
What you get
- A list of failing templates and the exact element or script behind each metric
- Implemented fixes or developer-ready tickets
- Before and after field data from Search Console
- A third-party script review with a keep, defer or remove decision for each
How We Do It
A clear process you can follow along with.
1. Start with field data
We open the Core Web Vitals report in Search Console and PageSpeed Insights field data to see which page groups fail and on which device. Lab scores alone can mislead, so field data decides what to fix.
2. Reproduce with lab tools
We use Lighthouse and the Chrome DevTools performance panel on the worst page templates, throttled to mobile conditions, to find the specific cause of each failing metric.
3. Fix LCP
We identify the LCP element, usually a hero image or large text block. Common fixes are resizing and compressing the image, serving a modern format, not lazy-loading it, preloading it, and cutting server response time and render-blocking CSS or scripts.
4. Fix CLS
We find elements that shift: images and embeds without width and height, late-loading banners, injected ads and web fonts that swap. We reserve space for each one so nothing moves after it loads.
5. Fix INP
We trace slow interactions in the performance panel and look for long JavaScript tasks. Typical fixes are removing or deferring third-party scripts, splitting heavy handlers and reducing work done on each click.
6. Ship in a safe order
We change one template at a time on staging, retest, then release, so a regression is easy to trace to a single change.
7. Verify with real users
Field data updates over a rolling window, so improvement is not immediate. We monitor Search Console and validate the fix there, and we confirm the current thresholds in Google documentation.
Mistakes We Help You Avoid
Common ways this goes wrong, and what we do instead.
Chasing a perfect Lighthouse score
A lab score is a test, not what users or Google see. We optimize the field metrics.
Lazy-loading the hero image
Delaying the main image makes LCP worse. We load it early and lazy-load only below-the-fold images.
Piling on optimization plugins
Several overlapping speed plugins can conflict. We use fewer, well-understood changes.
Ignoring third-party scripts
Chat widgets, tag managers and ad scripts are frequent INP and LCP culprits. We audit them one by one.
Frequently Asked Questions
What are Core Web Vitals?
They are Google's measures of real-user page experience: LCP for loading, INP for responsiveness and CLS for visual stability. Check current Google documentation for the exact thresholds.
Do Core Web Vitals affect rankings?
They are part of Google's page experience signals, but content relevance matters far more. Good scores help most when competing pages are otherwise similar.
Why does my score differ between tools?
Lab tools simulate one device and network, while field data aggregates real visitors. The two often disagree, and Search Console field data is the one Google uses.
How long until Search Console shows improvement?
Field data is collected over a rolling period, so expect a delay of several weeks after a fix. We validate the fix in Search Console and track it.
