If your website is slow, that is not just a user-experience problem. It is an SEO problem too.
For most local businesses, the damage happens in two places:
- People leave before they call, book, or fill out a form.
- Google uses page experience signals in Search, so slower pages can lose ground when competing pages are similarly relevant.
This is why all of my pricing packages come with a custom website built in. A fast site gives your SEO and Google Ads a stronger foundation before you spend more money trying to force traffic into a weak website.
Slow Sites Lose More Visitors
The first problem is simple: when a site drags, more people bounce.
Google’s official web.dev documentation says that websites that load quickly and respond quickly “engage and retain users better than websites that are slow to load, and feel sluggish.” See Why speed matters.
Google and SOASTA also reported that 53% of mobile visits are abandoned if a page takes longer than 3 seconds to load. That is already bad. Once a site stretches past 5 seconds, the fallout gets worse.
That is why this chart matters:
⚠️ CRITICAL STAT Once a site gets past 5 seconds, the drop-off gets expensive fast.
If you are paying for SEO or Google Ads, this means part of your traffic problem may actually be a website problem. You can get more people to the site and still lose leads because the site feels slow before your offer even has a chance to work.
Slow Sites Can Also Weaken Search Performance
The second problem is Google.
Google’s own documentation is direct on this point:
- Google’s page experience documentation says, “Google’s core ranking systems look to reward content that provides a good page experience.” See Understanding page experience in Google Search results.
- The same documentation says, “Core Web Vitals are used by our ranking systems.” See Google’s page experience FAQ.
- Google’s Core Web Vitals documentation also says Google “highly recommend[s] site owners achieve good Core Web Vitals for success with Search.” See Understanding Core Web Vitals and Google Search results.
That does not mean a fast site automatically ranks first. Google is clear that relevance still matters most. But when several businesses are competing for the same local searches, page experience can help separate the stronger result from the weaker one.
In plain English: a slow site can hurt SEO because Google wants to rank pages that work well for users.
Real Example: 10.8 Seconds vs 1.5 Seconds
Here is a direct comparison from the same business.
The Squarespace version was built to be as lean as possible and still took 10.8 seconds to load on mobile. The custom-built version of that same site loads in 1.5 seconds.
That means the custom-built version loads in about 86% less time. Put another way, it is about 7.2x faster.
Squarespace: 10.8 seconds
Custom Build: 1.5 seconds
This is the kind of gap that affects both SEO and lead generation:
- more people stay on the faster site
- the faster site gives Google a stronger page-experience signal
- paid traffic is less likely to get wasted on a sluggish landing page
Why This Happens So Often on Wix, Squarespace, and WordPress
The platform name is not the whole issue. The real problem is usually the stack behind the page:
- bloated themes
- page builders
- heavy plugins or apps
- extra scripts for tracking, popups, chat tools, and animations
- large images and unnecessary code shipped to every visitor
That combination makes it hard to stay fast, especially on mobile connections and older phones.
Custom-coded sites have a major advantage here because they can be built around exactly what the business needs and nothing else.
Speed Is a Foundation, Not a Bonus
If you want better results from local SEO or Google Ads, website speed should not be treated like a small technical cleanup item.
It is part of the foundation:
- it helps more visitors stay on the page
- it helps more of those visitors convert into leads
- it supports the kind of page experience Google wants to reward in Search
If your current Wix, Squarespace, or WordPress site feels heavy, slow, or hard to improve, the best next step may be replacing the foundation instead of patching it forever.
