Google's own tool for measuring website performance
If your website doesn't pass Lighthouse, you're losing rankings, customers and revenue.
Most businesses have no idea how well their website is actually performing.
Your site might look good, but is it Google-approved?
Is it fast enough to keep visitors engaged?
Is it optimised to rank higher on search engines?
Google has already built a tool to answer these questions - Lighthouse.
What is Google Lighthouse?
A free, built-in Google tool that measures how well your website performs.
It grades your site across four critical categories: Performance, SEO, Accessibility and Best Practices.
If your scores are low, your website is underperforming.
Why Does This Matter?
A low Lighthouse score means
Slow load times
Customers leave before seeing your offer.
Poor rankings
Google pushes your site down in search results.
Missed conversions
A bad user experience drives potential customers away.
A high Lighthouse score means
Faster site speeds
More visitors staying longer.
Better rankings
More organic traffic and leads.
Optimised performance
More sales and revenue.
A Lighthouse-optimised website isn't just about rankings - it's about real business results.
See why your Lighthouse score is one of the most important SEO factors on the next page.
Google ranks fast, high-scoring websites higher.
A slow website isn't just annoying - it's actively hurting your search rankings and costing you business.
Most businesses don't realise that Google penalises slow, underperforming websites.
If your website loads too slowly, your rankings drop.
If your website isn't optimised, Google pushes it down in search results.
If your Lighthouse score is low, your site is invisible to potential customers.
Your Lighthouse score isn't just a performance test - it's an SEO ranking factor.
How Lighthouse Affects SEO
Page Speed = Higher Rankings
Google prioritises fast-loading websites in search results.
A 1-second delay can drop conversions by 7% and increase bounce rates.
Technical SEO = Search Visibility
Lighthouse checks your website's structure, metadata and crawlability.
If your site isn't technically optimised, Google won't rank it well.
User Experience (UX) = More Clicks and Engagement
Lighthouse measures mobile-friendliness and accessibility.
A bad user experience = Google lowers your ranking.
The Hard Truth
A website with a high Lighthouse score performs better in search results.
If You're Not Ranking, You're Not Selling.
A low Lighthouse score means:
Fewer people find your business online.
Visitors leave before your site even loads.
You miss out on sales while competitors dominate search rankings.
A high Lighthouse score means:
More organic traffic.
Higher engagement and lower bounce rates.
More leads, more conversions, more revenue.
Google wants to rank high-performance websites.
Is yours one of them?
See how Lighthouse directly impacts your conversions and revenue on the next page.
Speed = More Customers, More Revenue.
A slow website isn't just frustrating - it's driving customers away and costing you sales.
Imagine this:
A visitor clicks on your website… and waits.
1 second… still loading.
2 seconds… still loading.
3 seconds… they leave and go to your competitor.
A slow website doesn't just hurt rankings - it kills conversions.
53% of visitors leave if a website takes longer than 3 seconds to load.
A 1-second delay can decrease conversions by 7%.
79% of users say they won't return to a slow website.
Faster websites = More engaged visitors = More sales.
How a Poor Lighthouse Score Costs You Customers
Slow Load Times = High Bounce Rates
If your website is slow, visitors don't stick around.
Google tracks this - high bounce rates hurt your rankings even more.
Frustrating User Experience = Lost Trust
A clunky, unoptimised website makes your business look unprofessional.
88% of consumers say they're less likely to return after a bad online experience.
Lost Sales = Lost Revenue
Every second of delay reduces customer satisfaction and conversions.
A slow checkout page? Abandoned carts and lost purchases.
The faster your website, the more customers stay, engage and buy.
What a High Lighthouse Score Means for Your Business
Lower Bounce Rates
Visitors stay longer and explore more.
Higher Engagement
Users click, browse and take action.
Increased Conversions
More leads, more sales, more revenue.
Your website should work for you - not against you.

Google tests your website in 4 critical areas.
Every website is graded on four key categories.
A weak score in any area = poor performance.
Google Lighthouse doesn't just check your website - it scores it.
Your Lighthouse score is made up of four key categories
Performance
Speed, load times and responsiveness.
SEO
Whether your site follows Google's best practices for search rankings.
Accessibility
Ensuring a smooth user experience for all visitors.
Best Practices
Security, HTTPS and mobile optimisation.
Each category gets a score from 0-100.
90+ = Excellent
Your site is fast, optimised and Google-friendly.
50-89 = Needs Improvement
Some areas are slowing you down.
0-49 = Failing
Your website is losing traffic, rankings and conversions.
Breaking Down the 4 Lighthouse Categories
Performance
Measures page speed, load time and visual stability.
Slow load times = higher bounce rates and lower search rankings.
SEO
Checks meta tags, alt text and structured data.
If your site isn't optimised for search engines, Google won't rank it well.
Accessibility
Ensures all users, including mobile and visually impaired visitors, can navigate your site easily.
Google rewards mobile-friendly, user-friendly websites.
Best Practices
Evaluates security, HTTPS encryption and coding errors.
A low score here = your website might not be trustworthy.
A low Lighthouse score in any category weakens your entire website.
Why Most Websites Fail Lighthouse Tests
They're built for looks, not performance.
They use bloated code and slow-loading images.
They're missing key SEO and accessibility best practices.
If your Lighthouse score is below 90, your website needs serious improvements.
