Core Web Vitals & Speed
LCP, INP and CLS measured on real page loads rather than a lab score, then the render path fixed where the numbers say it hurts.
What usually goes wrong
A lab score is a simulation on a machine that is not your customer's. What Google uses is field data from real loads on real phones on real connections, and the two often disagree by seconds.
You would notice
- A high lab score and a failing field report at the same time
- The page looks loaded but nothing responds for a moment
- Content jumps while it is loading
- Mobile is much worse than desktop and nobody knows why
The work
Core Web Vitals & Speed, line by line.
Each line is work that gets done and can be checked afterwards. None of it is a promise about where you will rank — nobody can honestly make that one.
- 01LCP, INP and CLS read from field data, not a lab score
- 02The render path traced to what is actually blocking it
- 03Image formats, sizing and preload for the largest element
- 04Third-party scripts weighed against what they cost
- 05Re-measured after the fix, so the change is provable
In practice
The thresholds, and where they land
Illustrative example. Values are the 75th percentile of real loads, which is the number Google actually uses.
Questions
Asked often enough to answer here.
Do Core Web Vitals really affect rankings?
They are a tiebreaker, not a lever. They will not lift a page that does not deserve to rank, and they will lose you positions you already hold against a competitor who is otherwise equal.
Can you fix this without a developer?
Some of it. Image formats, preloads and third-party scripts are often ours to change. Server response time usually is not, and we will say which is which.
How do I know it worked?
The same measurement, before and after, from field data rather than a lab run. It takes about 28 days for field data to fully reflect a change.

Work that usually travels with it.
- Technical SEO AuditA full crawl of the site against how search engines actually read it: status codes, canonicals, indexability, duplicate paths, and what is quietly blocking the rest.
- Site Architecture & Internal LinkingHow pages are grouped, how deep they sit, and how link equity moves between them. Most sites lose more here than they do on backlinks.
- Structured Data & SchemaValid JSON-LD for the page types that earn rich results, and removal of the markup that only earns warnings.
- Indexation & Crawl BudgetGetting the right pages indexed and the wrong ones out, with robots, sitemaps and parameter handling that agree with each other.
