A Slow Site Buries You in Google
Google measures how fast your pages load and uses it to decide where you rank. If your site is slow, you get pushed down the results page no matter how good your content is. These are the speed checks Google runs on every page, and the targets we hit for you.
How fast your page shows up
Largest Contentful Paint
Good: under 2.5s
Needs Work: 2.5-4s
Poor: 4s or more
How fast it responds to a tap
Interaction to Next Paint
Good: feels instant
Needs Work: noticeable lag
Poor: feels frozen
How steady the page stays
Cumulative Layout Shift
Good: nothing jumps
Needs Work: some shifting
Poor: content jumps around
What Speed Does to Your Rankings
- Google counts page speed as a ranking signal, so a slow site gives up ground
- The top few results get most of the clicks on a mobile search
- Slipping from third place to tenth means far fewer visitors
User Experience Impact: The 3-Second Rule
People form a first impression almost instantly, so a slow load hurts how they see your brand before the content even shows up.
Over 3 seconds53% of mobile site visitors leave(Google/SOASTA, 2017)
What Slow Pages Do:
- Every extra second means fewer pages viewed per visit
- Every extra second leaves visitors less satisfied
- Shoppers expect pages to load fast, and leave the ones that don't

The same standard applies to every client build
- Every site we ship targets 90+ mobile Lighthouse performance on the throttled test, not the easy desktop one, and a 95+ average across all four categories
- Above-the-fold content renders on the server, so there's no blank screen while the page hydrates
- Images compressed and sized per viewport, fonts self-hosted, scripts deferred
- We measure after every deploy, not just at launch
Common Issues
8 Reasons Your Website Feels Slow
The slow sites we audit usually have five to seven of these, and every one of them costs you customers and rankings.
High Impact
Huge, Heavy Images
Almost every time when we audit a slow site
Problem
Full-size phone photos uploaded straight to the site, often several megabytes each.
Symptoms
Images alone make up most of the page weight, and they're the single biggest reason a page loads slowly.
Our Fix
We compress and right-size every image, and load lower images only as visitors scroll to them.
Expected Improvement
40 to 70% smaller pages, and content that appears 2 to 4 seconds sooner
High Impact
Code That Blocks the Page
Almost every time when we audit a slow site
Problem
Non-essential code runs before anything shows up, holding the whole page hostage.
Symptoms
Visitors stare at a blank white screen for 2 to 6 seconds before anything appears.
Our Fix
We let the page show first and load the extra code in the background, in the right order.
Expected Improvement
1 to 3 seconds faster, and the site feels responsive right away
High Impact
Bloated Design Code
Most of the time when we audit a slow site
Problem
Oversized styling files that have to download before the page can paint.
Symptoms
The page flashes unstyled for a moment, or just sits blank longer than it should.
Our Fix
We trim the styling down to what each page actually needs and load the rest after.
Expected Improvement
0.5 to 2 seconds faster first paint
Medium Impact
No Memory Between Visits
Most of the time when we audit a slow site
Problem
The browser re-downloads the entire site from scratch on every single visit.
Symptoms
Returning visitors wait just as long as first-timers, and your server works harder than it needs to.
Our Fix
We set the site to remember its files, so repeat visits load almost instantly.
Expected Improvement
60 to 90% faster for returning visitors
High Impact
Slow Hosting
Often when we audit a slow site
Problem
Cheap or overloaded hosting that takes too long just to start sending the page.
Symptoms
There's a noticeable delay before anything happens, and it drags down every other part of the site.
Our Fix
We move you to faster hosting and tune the back end so the server responds quickly.
Expected Improvement
A response that starts up to 1.5 seconds sooner
High Impact
Too Many Marketing Scripts
Most of the time when we audit a slow site
Problem
A pile of add-ons for ads, analytics, chat, and tracking, all loading at once.
Symptoms
Each one adds a fraction of a second, and together they pile up into a 2 to 5 second delay.
Our Fix
We keep the tools that earn their place, cut the ones that don't, and load what's left quietly in the background.
Expected Improvement
1 to 4 seconds faster before the page is fully usable
Medium Impact
Content That Jumps Around
Often when we audit a slow site
Problem
Images, ads, and fonts pop in late and shove everything else around as the page loads.
Symptoms
Visitors tap the wrong thing, lose their place reading, and Google marks the page down for it.
Our Fix
We reserve space for everything up front so the page loads steady and stays put.
Expected Improvement
A page that stays still instead of shifting under your visitors
Medium Impact
A Cluttered Back End
Often when we audit a slow site
Problem
Years of leftover data, old drafts, and spam piling up behind the scenes.
Symptoms
The site gets slower to load and eats up more server resources than it should.
Our Fix
We clean out the clutter and tune the back end so it runs lean again.
Expected Improvement
30 to 60% faster behind the scenes

Core Web Vitals
Three Checks for a Better Page Experience
Core Web Vitals measure loading, responsiveness, and visual stability. Here's what each one tells us about your website, and how we improve it.
Core Web Vitals show how quickly the main content appears, how promptly the page responds, and whether its layout stays steady. Google uses them in its ranking systems, alongside other signals. Good scores support a better experience; they don't guarantee a particular search position.
Worth knowing: Google grades you on what real visitors actually experience, not a lab test. Most of your visitors need a fast experience for you to pass. We use field data where available and lab tests to investigate specific problems.
How Fast Your Page Shows Up
Largest Contentful Paint
What it means:
How long a visitor waits before the main thing on the page (your headline or hero image) actually appears.
Why it matters:
People decide a site has loaded once they see real content. If that takes too long, they assume it's broken and leave.
The targets:
GoodUnder 2.5 seconds
Needs Improvement2.5-4 seconds
PoorOver 4 seconds
What usually causes it:
- A giant, uncompressed hero image
- Extra code that runs before the image is allowed to load
- Slow hosting that's sluggish just to get started
- Nothing telling the browser to load the main image first
How we fix it:
- Compress and right-size your hero image
- Tell the browser to load the main image first, not last
- Clear the code roadblocks that delay it
- Move you to faster hosting so the page starts sooner
Illustrative example: 6.2s down to 1.2s, 80% faster
How Fast It Responds to a Tap
Interaction to Next Paint
What it means:
How quickly the page reacts every time a visitor clicks a button, taps a menu, or fills in a field, not just the first.
Why it matters:
Nothing loses a visitor faster than tapping something and having nothing happen. The site feels frozen, and they give up.
The targets:
GoodUnder 200ms
Needs Improvement200-500ms
PoorOver 500ms
What usually causes it:
- Heavy code tying up the page in the background
- Marketing and tracking tools hogging the browser
- Big chunks of work that lock things up while they run
- The whole site loading at once instead of in pieces
How we fix it:
- Break up the heavy work into small, quick pieces
- Push non-essential code to load in the background
- Remove or delay the heaviest marketing tools
- Load only the code each page actually needs
Typical result: a page that reacts the instant someone taps
How Steady the Page Stays
Cumulative Layout Shift
What it means:
Whether the page loads steadily, or whether buttons and text jump around as images and ads pop in late.
Why it matters:
Visitors tap the wrong thing when a button shifts, or lose their place when a paragraph jumps. It feels cheap, and Google marks you down for it.
The targets:
GoodUnder 0.1
Needs Improvement0.1-0.25
PoorOver 0.25
What usually causes it:
- Images and videos with no space saved for them
- Ads and embeds dropping in and pushing things around
- Fonts loading late and reflowing the text
- New content squeezing in above what you're reading
How we fix it:
- Save the right amount of space for every image and video
- Hold a spot for ads and embeds before they load
- Load fonts so the text doesn't jump when they arrive
- Stop content from shoving the page around as it loads
Typical result: a page that loads rock-steady
