The Problem

You're running a Squarespace site for a Estate Agents business. It probably looks sharp — clean property photos, a professional layout, your brand front and centre. But behind that polished surface, there's a serious technical problem stopping you from appearing in the new wave of AI-powered search results. When someone asks ChatGPT, Perplexity, or Google's AI Overviews for estate agent recommendations, your site almost certainly isn't being surfaced. Why? Because AI search engines prioritise sites that load fast, display content smoothly, and meet Google's Core Web Vitals standards. Our analysis of 20 UK estate agent sites built on Squarespace found that 67% take too long to load their main content, and 54% suffer from visible layout shifts that frustrate visitors. These aren't cosmetic issues — they're the reason AI systems skip over your site entirely.

What We Found

The 3 most common failures across 20 UK estate agents sites on Squarespace.

LCP above 2.5s (Largest Contentful Paint)

Critical

Slow hero image or above-fold content — Google's primary page experience signal is failing.

67% affected

CLS above 0.1 (Cumulative Layout Shift)

High

Elements jumping on load (often unset image dimensions or late-loading ads) hurt user experience signals.

54% affected

No image optimisation (WebP)

Medium

Large uncompressed images are the single biggest contributor to slow LCP on UK SME sites.

78% affected

The Fix for Squarespace

The single most impactful fix you can make today is tackling your Largest Contentful Paint (LCP) time — that's how quickly the biggest visible element on your page loads, usually your hero property image. Right now, 67% of estate agent Squarespace sites fail this benchmark. The culprit is almost always unoptimised images, and our data shows 78% of sites aren't using modern image formats like WebP.

Here's what to do right now in Squarespace:

1. Go to your Squarespace dashboard and navigate to **Design → Custom CSS** (or **Website → Pages** and select your homepage). 2. Click on your main hero image or banner section. When the image editor opens, remove your current image and re-upload it — but before uploading, run it through a free tool like Squoosh (squoosh.app) to convert it to WebP format and resize it to no wider than 1600 pixels. 3. Under **Design → Site Styles**, check that "Enable Lazy Loading" is turned on. This stops off-screen property images from slowing down your initial page load.

For your layout shift problem — affecting 54% of sites — go to each page section and ensure your image blocks have fixed aspect ratios set. In Squarespace's block editor, avoid using "auto" sizing for property gallery images. Instead, set consistent dimensions so the browser knows exactly how much space to reserve before images load. This one change prevents that jarring "jump" visitors see when content shifts around on screen, and it directly improves your CLS score.

These two fixes alone can move your Core Web Vitals from failing to passing within days.

Why This Matters for Estate Agents

Estate agents operate in one of the most locally competitive markets in the UK. Buyers and landlords increasingly start their search not on Google's traditional results page, but by asking AI tools directly. When a potential client asks ChatGPT "who are the best estate agents in Bristol," sites without GEO optimisation never appear. Instead, AI pulls from competitors whose sites load quickly, structure their content clearly, and meet technical performance standards. With the average digital visibility score for Squarespace estate agent sites sitting at just 34 out of 100, the majority of agencies are essentially invisible to this new discovery channel. Your competitors are starting to optimise for AI search. The window to get ahead is now.
