Heavy images and media
Modern formats, correct sizes, lazy loading that does not delay the main image, and properly sized video embeds.
Core Web Vitals expert
A Core Web Vitals expert who makes your site fast where it counts: on real phones.
Google measures how quickly your main content appears, how stable the page stays and how fast it responds to a tap. I find what is dragging those numbers down and fix it, so visitors stay and your pages stop losing ground to faster competitors.

What a Core Web Vitals expert actually does
Core Web Vitals are three measurements Google uses to judge page experience. Largest Contentful Paint (LCP) is how fast the main content shows up. Interaction to Next Paint (INP) is how quickly the page reacts when someone taps or clicks. Cumulative Layout Shift (CLS) is how much the page jumps around while loading.
A good score in a lab test does not mean much if real visitors on mid-range phones still wait. I look at field data from real users first, then trace each slow metric back to its cause: an oversized hero image, a render-blocking script, a late-loading font, a chat widget that freezes the page.
Speed is part of technical SEO, and it also affects conversions directly. It is rarely the only reason a site fails to rank, so I check it alongside everything else in an SEO audit.
Where slow pages usually lose time
Render-blocking code
CSS and JavaScript that holds up the first paint, deferred or removed where it is safe to do so.
Fonts and layout jumps
Font loading and reserved space for images, ads and embeds so nothing shifts after the page appears.
Plugins and third-party scripts
Chat widgets, trackers and tag managers that slow every page for little return.
Server and caching
Hosting response time, page caching and CDN setup, tuned to how your site is actually built.
Responsiveness (INP)
Long tasks that make buttons and menus feel stuck, found and broken up.
How a speed project runs
1
Measure real users
I start with Search Console and field data, not only a single test run.
2
Find the cause
Each failing metric is traced to the specific file, script or element behind it.
3
Fix in order of impact
The changes that move scores most come first, with the risk of each one explained.
4
Test on devices
I check on mid-range phones and slower connections, where most problems hide.
5
Watch the field data
Real-user numbers take weeks to update, so I track them until they settle.
A fast, stable site versus a slow one
Passing Core Web Vitals
- Main content appears quickly
- Nothing jumps while reading
- Taps respond instantly
- Lower bounce, better conversions
- No speed penalty to overcome
Failing Core Web Vitals
- ✓ Blank screen while images load
- ✓ Buttons move as you tap them
- ✓ Menus that lag
- ✓ Visitors leaving before the page loads
- ✓ A tie-breaker lost to faster rivals
Speed is one part of the picture
Fast pages help, but they will not rescue weak content. Once the site is quick, on-page SEO makes each page match its searcher and content SEO fills the gaps.
If you are about to change platform or redesign, plan speed in from the start with a site migration check, which is far cheaper than fixing it afterwards.
Core Web Vitals questions, answered plainly
What are Core Web Vitals?
They are three user-experience measurements from Google: Largest Contentful Paint for loading, Interaction to Next Paint for responsiveness and Cumulative Layout Shift for visual stability.
Do Core Web Vitals affect rankings?
Yes, as part of Google’s page experience signals. They rarely beat strong, relevant content, but between similar pages they can decide who ranks higher. They also affect how many visitors stay.
What is a good score?
Google considers LCP under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1 to be good, measured for most real visitors.
Why does my site pass in a speed test but fail in Search Console?
Lab tests run one page on a fast connection. Search Console uses data from real visitors on all kinds of devices, which is usually slower.
Will you change my design?
Only where it is the cause. Most fixes are behind the scenes. If a design element is the problem, I explain the trade-off and let you decide.
How long until Search Console shows the improvement?
Field data uses a rolling 28-day window, so expect roughly a month before the report fully reflects your fixes.
