Google PageSpeed Scores Updated with Lighthouse 8.0

Published

on

Google updated Lighthouse 8.0 and one of the important changes is to change the weights of the different speed metrics. The changes are estimated to make it easier for most sites to achieve higher page speed scores. Cumulative Layout Shift scores will likely trend higher while other metrics become stricter.

Google Lighthouse 8.0

Lighthouse is a tool that helps publishers, developers and SEOs measure page speed and other metrics related to accessibility and SEO. Lighthouse powers the online PageSpeed Insights tool and is shipped as a developer tool in Chrome.

The new Lighthouse version 8.0 will ship in Chrome 93 but is available right now in PageSpeed Insights.

Changes to Google Lighthouse Tool

  • Performance score has been re-weighted
  • Total Blocking Time (TBT) Scoring is Stricter
  • First Contentful Paint (FCP) Scoring is Stricter
  • Cumulative Layout Shift (CLS) Scoring is Less Strict

How Scores Have Changed

According to Google’s FAQ, about 20% of sites will see a drop of up to five points, while 20% might not see much change.

Google estimates that approximately 60% of sites will see a positive change, from moderate to 5 points improvement or higher.

There are estimated to be more winners with Lighthouse 8.0 that score higher than sites that score less well.

Here are Google’s estimates on expected changes and explanation:

“~20% of sites may see a drop of up to 5 points, though likely less
~20% of sites will see little detectable change
~30% of sites should see a moderate improvement of a few points
~30% could see a significant improvement of 5 points or more

The biggest drops in scores are due to TBT scoring becoming stricter and the metric’s slightly higher weight. The biggest improvements in scores are also due to TBT changes in the long tail and the windowing of CLS, and both metrics’ higher weights.”

The Total Blocking Time metric is described as being stricter and could have been even more strict. But the engineers decided to dial it back so as to not be too “jarring.

According to the TBT GitHub page:

“But we think these as our control points would be too jarring and aggressive for now. Still, there’s room to improve, so we’re doing a small shift of TBT being scored more strictly.”

Before and After Lighthouse Scores

Google published a Lighthouse Scoring Calculator showing what the differences are between versions 8.0, 6 and 7 and version 5.

Below are screenshots comparing the exact same Lighthouse scores between the different versions (6/7 and 8.0).

In the example below it shows that version 8.0 results in a lower score.

Below are a comparison of the same Lighthouse scores between versions showing a four point drop between versions 8.0 and 6/7.

Lighthouse API Update

Google published a note about changes to the API:

“The new Cumulative Layout Shift definition is now the default metric surfaced as cumulative_layout_shift, the previous Cumulative Layout Shift metric will be available for a limited time as it is phased out as experimental_uncapped_cumulative_layout_shift.

Largest Contentful Paint has undergone adjustments in recent Chrome versions and has been updated similarly in CrUX.

First Contentful Paint tri-binning thresholds have been updated to be: [0-1.8s], (1.8s-3s), [3s-∞].”

Check Out the New Page Speed Scores

The new scores are available immediately at the PageSpeed Insights tool.

Lighthouse 8.0 will be available in Chrome 93 which is currently scheduled to ship on August 31, 2021.

Google to pay $391.5 million settlement over location tracking, state AGs say

Google to pay $391.5 million settlement over location tracking, state AGs say

Google has agreed to pay a $391.5 million settlement to 40 states to resolve accusations that it tracked people’s locations in violation of state laws, including snooping on consumers’ whereabouts even after they told the tech behemoth to bug off.

Louisiana Attorney General Jeff Landry said it is time for Big Tech to recognize state laws that limit data collection efforts.

“I have been ringing the alarm bell on big tech for years, and this is why,” Mr. Landry, a Republican, said in a statement Monday. “Citizens must be able to make informed decisions about what information they release to big tech.”

The attorneys general said the investigation resulted in the largest-ever multistate privacy settlement. Connecticut Attorney General William Tong, a Democrat, said Google’s penalty is a “historic win for consumers.”

“Location data is among the most sensitive and valuable personal information Google collects, and there are so many reasons why a consumer may opt out of tracking,” Mr. Tong said. “Our investigation found that Google continued to collect this personal information even after consumers told them not to. That is an unacceptable invasion of consumer privacy, and a violation of state law.”

Location tracking can help tech companies sell digital ads to marketers looking to connect with consumers within their vicinity. It’s another tool in a data-gathering toolkit that generates more than $200 billion in annual ad revenue for Google, accounting for most of the profits pouring into the coffers of its corporate parent, Alphabet, which has a market value of $1.2 trillion.

The settlement is part of a series of legal challenges to Big Tech in the U.S. and around the world, which include consumer protection and antitrust lawsuits.

Though Google, based in Mountain View, California, said it fixed the problems several years ago, the company’s critics remained skeptical. State attorneys general who also have tussled with Google have questioned whether the tech company will follow through on its commitments.

The states aren’t dialing back their scrutiny of Google’s empire.

Last month, Texas Attorney General Ken Paxton said he was filing a lawsuit over reports that Google unlawfully collected millions of Texans’ biometric data such as “voiceprints and records of face geometry.”

The states began investigating Google’s location tracking after The Associated Press reported in 2018 that Android devices and iPhones were storing location data despite the activation of privacy settings intended to prevent the company from following along.

Arizona Attorney General Mark Brnovich went after the company in May 2020. The state’s lawsuit charged that the company had defrauded its users by misleading them into believing they could keep their whereabouts private by turning off location tracking in the settings of their software.

Arizona settled its case with Google for $85 million last month. By then, attorneys general in several other states and the District of Columbia had pounced with their own lawsuits seeking to hold Google accountable.

Along with the hefty penalty, the state attorneys general said, Google must not hide key information about location tracking, must give users detailed information about the types of location tracking information Google collects, and must show additional information to people when users turn location-related account settings to “off.”

States will receive differing sums from the settlement. Mr. Landry’s office said Louisiana would receive more than $12.7 million, and Mr. Tong’s office said Connecticut would collect more than $6.5 million.

The financial penalty will not cripple Google’s business. The company raked in $69 billion in revenue for the third quarter of 2022, according to reports, yielding about $13.9 billion in profit.

Google downplayed its location-tracking tools Monday and said it changed the products at issue long ago.

“Consistent with improvements we’ve made in recent years, we have settled this investigation which was based on outdated product policies that we changed years ago,” Google spokesman Jose Castaneda said in a statement.

Google product managers Marlo McGriff and David Monsees defended their company’s Search and Maps products’ usage of location information.

“Location information lets us offer you a more helpful experience when you use our products,” the two men wrote on Google’s blog. “From Google Maps’ driving directions that show you how to avoid traffic to Google Search surfacing local restaurants and letting you know how busy they are, location information helps connect experiences across Google to what’s most relevant and useful.”

The blog post touted transparency tools and auto-delete controls that Google has developed in recent years and said the private browsing Incognito mode prevents Google Maps from saving an account’s search history.

Mr. McGriff and Mr. Monsees said Google would make changes to its products as part of the settlement. The changes include simplifying the process for deleting location data, updating the method to set up an account and revamping information hubs.

“We’ll provide a new control that allows users to easily turn off their Location History and Web & App Activity settings and delete their past data in one simple flow,” Mr. McGriff and Mr. Monsees wrote. “We’ll also continue deleting Location History data for users who have not recently contributed new Location History data to their account.”
