Local Real Estate Sites Fail Core Web Vitals More Than Any Local Sector We Measured. Only 40% Pass.

Real estate sites are covered in listing photos and interactive maps, so the easy assumption is that they are slow. For the local agent site, the assumption is correct, and it is the biggest surprise in this series. Across 117 local brokerages and agent sites we measured in 32 metros, only 40% pass Core Web Vitals, the lowest of any local business we have looked at. The national portals with far more listings and imagery are the faster tier, and the small local site is the one that struggles.

For an agent, the website is where a buyer starts. Someone scrolling listings at midnight taps a result, and the homepage has a few seconds to load the search before they bounce back to Zillow. Real estate is a business of high-value, low-frequency transactions, so every serious visitor matters, and a homepage that makes them wait through a loading map is a lead handed to the portal instead. Speed on that page is the pipeline.

The figures come from the Chrome User Experience Report, Google's record of how real buyers experience these sites on their own phones, across 117 local agent and brokerage sites ranking in search in 32 US metros. National portals and franchisor corporate domains were set aside as a separate comparison, so the sample is the independent local presence, and the diagnosis for it is unusually clean.

The readings come from the Chrome User Experience Report, which captures loading, responsiveness, and layout stability from the browsers of real home buyers pulling up these sites on their own phones and networks, not from a synthetic lab test. The real estate sample was built the way a buyer actually shortlists an agent in Google: 117 local brokerages and agent or team sites that surface for real estate, realtor, and homes-for-sale queries across 32 US metro areas, with the national portals (Zillow, Redfin, Realtor.com) and franchisor corporate domains held out and measured as a separate comparison tier.

This is deliberately a competitive-search set, not a census. It reflects the independent local presence a buyer actually sees when they open Google to compare agents in their city, which is the pool that decides who gets the showing request; it is not an attempt to inventory every real estate website on the internet.

Passing Core Web Vitals requires clearing all three of Google's thresholds simultaneously at the 75th percentile of a site's mobile visitors: main content painted in under 2.5 seconds (good LCP), interactions responding in under 200 milliseconds (good INP), and a layout stable enough to score under 0.1 on cumulative shift (good CLS). It is a strict all-three bar, and only two in five local real estate sites clear it.

Group the 117 local real estate sites together and 40.2% pass Core Web Vitals on mobile, the lowest pass rate of the local sectors we have rebuilt, below local healthcare, law, and finance. The failure is almost entirely loading. Good LCP is 59.8%, the weakest loading figure of any sector in this series, while responsiveness stays high at 97.6% good INP and stability at 91.5% good CLS. The median local site paints its main content in 2.4 seconds, past the passing line, and the slowest run to 5 or 6 seconds.

The cause is not the photos by themselves. It is the interactive property-search map and live listing feed, the IDX integration that nearly every agent site embeds so visitors can search homes without leaving. That widget loads a mapping library, pulls listing data, and renders photo tiles, all on the homepage, before the content a visitor came to see. Add a large photo slider at the top and the first paint is delayed twice over. A few of the slowest sites also fail on layout shift, because the map and photos load late and push the rest of the page down as they appear.

Set the local sites against the national search portals and the picture changes. In a separate portal set, sites like Redfin and Trulia passed about 64% of the time, despite carrying far more listings and imagery. The difference is engineering. A portal builds its own map and search, and optimizes it: lazy-loading tiles, deferring the heavy library, reserving layout space so nothing jumps.

The local agent embeds a third-party version of the same feature and takes its default behavior, which is to load everything up front. The portal is fast because it controls the widget; the local site is slow because it inherits one. The photos are a scapegoat. The interactive search that agents rightly want is the actual weight, and it is a loading-order problem rather than a feature anyone has to give up.

National portals, measured separately, pass about 64%.

For a local agent or brokerage this is the clearest single-lever fix in the series. Responsiveness holds at 97.6% good INP and layout at 91.5% good CLS. Loading is where you fail, at 59.8% good LCP, the weakest loading figure of any sector we measured, with a median of 2.4 seconds and the slowest sites running to 5 or 6.

The weight is the embedded IDX property-search map and the homepage photo slider, not the listing photos themselves. Defer the map widget until a visitor scrolls to it, replace the auto-playing slider with a single optimized hero image, and reserve layout space so the map and photos do not push the page around as they load. You give up none of the search buyers came for.

The portals show what good looks like. Redfin, Trulia and their peers pass about 64% of the time with far more listings, because they engineer the map a local agent simply embeds and inherits at its load-everything default. Fix the loading order and most of these sites cross from failing to passing, and the agent stops handing midnight browsers back to Zillow.
