Skip to content 
A contractor website should load its main content in under 2.5 seconds on a phone. That is Google’s target for Largest Contentful Paint, and it is where most home service sites fail.
The usual causes are oversized project photos, old tracking scripts, and cheap shared hosting. All three are fixable without a full rebuild.
This guide covers the six fixes we check first in technical SEO for home service companies, in the order that gets the biggest gains.

The Three Scores Google Uses
Google grades page experience with three Core Web Vitals. Each one has a clear pass line.
- Largest Contentful Paint (LCP): 2.5 seconds or less. This measures how fast the biggest item on screen loads, usually your hero photo.
- Interaction to Next Paint (INP): 200 milliseconds or less. This measures how fast the page reacts when someone taps a button.
- Cumulative Layout Shift (CLS): 0.1 or less. This measures how much the page jumps around while it loads.
Google judges these on mobile first. A site that passes on your office desktop can still fail on a homeowner’s phone.
Test Your Site in Five Minutes
Run your pages through PageSpeed Insights. It is free and uses the same scores Google does.
Test three pages, not just the homepage: your top service page, your gallery, and your contact page. Service pages get most of your paid and organic traffic, so they matter most.
Look at the mobile tab first. Write down LCP, INP, and CLS for each page so you can measure your fixes.
1. Shrink Your Project Photos
Project galleries are the most common reason contractor sites load slowly. A phone camera saves photos at 3 to 5 MB each. Upload 30 of those to one gallery page and the page weighs over 100 MB.
Fix photos before you upload them:
- Resize them to 1,600 pixels wide. Nobody views a gallery wider than that.
- Convert them to WebP. It cuts file size by roughly a quarter to a third compared to JPEG at the same quality.
- Aim for under 200 KB per gallery photo.
Turn on lazy loading for images below the fold. Never lazy load the hero image at the top of the page. That image is usually your LCP, and delaying it makes the score worse.
If nobody on your team has time for this, fold it into your website management plan so every new upload gets compressed. For tips on shooting the photos themselves, see our guide to taking high-performing pictures for your site.
2. Stop the Page From Jumping
Layout shift happens when something loads late and pushes content down. A homeowner goes to tap “Call Now” and hits a review widget instead.
The usual causes on contractor sites:
- Images without a set width and height
- Review and rating widgets that load after the page
- Chat bubbles, cookie banners, and promo bars that slide in from the top
Set dimensions on every image. Reserve fixed space for widgets so they fill a box instead of pushing text down.
3. Remove Scripts You Forgot About
Most contractor sites carry scripts from past vendors. It is common to find old call tracking code, retired chat tools, and pixels from ad accounts nobody uses.
Every third-party script adds download time and slows down taps, which hurts INP.
Open Google Tag Manager and your site’s header code. List every script and the tool it belongs to. If nobody can name the tool or who uses it, remove it.
4. Turn On Caching and Compression
Caching saves a ready-made copy of each page, so the server does not rebuild it for every visitor. Compression shrinks your code files before they travel to the phone.
Check these four settings with your host or developer:
- Page caching turned on
- Browser caching for images, CSS, and JavaScript
- Brotli or Gzip compression turned on
- A CDN that serves images from a server close to the visitor
On WordPress, one caching plugin covers most of this. Only run one at a time. Two caching plugins will conflict.
5. Keep the Call Button Fast
For a home service business, the phone number is the most important element on the page. It should load with the page itself, not after a script runs.
Put the click-to-call link in plain HTML in the header. Use a sticky call bar on mobile so the number stays on screen as visitors scroll.
Test it on your own phone over cellular data, not Wi-Fi. If the number takes longer than two seconds to appear, fix that first.
6. Check Your Hosting
Cheap shared hosting puts your site on a server with hundreds of others. When their traffic spikes, your pages slow down.
Look at Time to First Byte (TTFB) in PageSpeed Insights. Google’s guideline is 0.8 seconds or less. If yours runs higher on every page, the server is the bottleneck and no plugin will fix it.
Move to managed WordPress hosting before you spend money on design changes.
Why Speed Matters More for Emergency Trades
Speed hurts every trade, but urgent calls feel it most. A homeowner with a flooded basement or a backed-up septic line taps the first result and leaves if it stalls.
Our guide to LCP and Core Web Vitals for septic companies shows how this plays out when every call is an emergency.
How Speed Affects Your Lead Cost
If you run Google Ads, you pay for the click whether the page loads or not. A visitor who leaves before your page appears still costs you the full click price.
Faster pages turn more of those paid clicks into calls. Landing page experience is also part of your Google Ads Quality Score, so speed can lower your cost per click too.
Frequently Asked Questions
What is a good page speed for a contractor website?
Aim for your main content to load in 2.5 seconds or less on mobile. That is Google’s passing line for Largest Contentful Paint. Also keep taps responding in under 200 milliseconds and layout shift under 0.1. Test your top service page, not only your homepage.
Does website speed affect Google rankings?
Yes. Core Web Vitals are part of Google’s page experience signals. They rarely beat strong content on their own, but they can decide close rankings between two local competitors. Speed also affects conversions, since slow pages lose visitors before they call.
Do I need a new website to fix speed problems?
Usually not. Most speed problems come from oversized images, extra scripts, missing caching, or weak hosting. All of these can be fixed on your current site. A rebuild makes sense only when the theme or page builder itself loads too much code on every page.
How often should I check my site speed?
Check your top pages once a month and after any major change, such as a new plugin, widget, or gallery upload. Speed scores drift as you add content and tools. Catching a slowdown early is easier than fixing ten problems at once.
