PageSpeed Insights now uses Lighthouse 8.4.0 which features two brand new audits. The most important addition helps publishers diagnose a widespread problem that negatively impacts the Largest Contentful Paint metric. This new audit will help publishers achieve better Largest Contentful Paint (LCP) scores.

Largest Contentful Paint

There has been a longtime issue with Largest Contentful Paint (LCP) that the newest version of Lighthouse, 8.4.0 will help diagnose.

It was discovered that lazy loading images was a good approach for making the main main part of the content visible and interactive on a mobile device faster.

Previous to lazy loading the images that were below the fold (not visible in the browser screen viewport) would download in the background.

That had the effect of slowing down the visibility and interactivity of the content that was in the site visitor’s viewport.

When images that are outside of the mobile viewport load in the background they actually slow down the rendering of the visible part of the web page.

By adding the Lazy Load HTML attribute to images the browser would know to not download the images (that are outside of the viewport) until later.

This has the effect of increasing the Page Speed.

But lazy loading elements that are in the Largest Contentful Paint viewport has a negative effect and this is one of the things that Lighthouse 8.4.0 addresses.

Negative Impact of Lazy Loading All Images

WordPress 5.4 introduced native lazy loading of images. Before implementing the change the developers tested the speed improvements and discovered that adding the lazy load HTML attribute to all images resulted in a speed gain.

However that was an imperfect implementation of the lazy load attribute because WordPress was now adding the lazy load attribute to the featured image which is an element that is generally in a site visitor’s viewport when visiting a web page.

That added a negative impact to the Largest Contentful Paint (LCP) metric and introduced a slight negative user experience.

The gains from adding lazy load outpaced the losses from the hit to the LCP metric, so WordPress proceeded with this.

Google however noticed that after implementation of lazy loading in the WordPress core that the Lowest Contentful Paint (LCP) scores started dropping a little bit.

In an article that Google published on Web.dev about the performance effect of too much lazy loading, they researched the data of actual websites and discovered that sites with too much lazy loading suffered from poor LCP scores.

They discovered that aggressive lazy loading implementations was the reason and they learned that this was an issue specific to WordPress sites.

Google confirmed that WordPress scores for LCP were indeed dropping.

The authors concluded:

“…the lazy-loading technique used by WordPress very clearly helps reduce image bytes but at the cost of a delayed LCP.”

Lighthouse 8.4.0 Adds LCP Lazy Load Audit

Publishers may have seen their Largest Contentful Paint (LCP) scores dropping and not understand why they were getting worse. Lighthouse 8.4.0 solves this issue by adding an audit specifically for diagnosing this problem.

All images in the Largest Contentful Paint viewport, the part of the web page that a visitor sees first, should not be lazy loaded.

Lighthouse 8.4.0 will detect if there are any elements in the LCP viewport that are lazy loaded.

A Chrome Developer page describes how Lighthouse 8.4.0 works:

“Lighthouse will now detect if the Largest Contentful Paint (LCP) element was a lazy-loaded image and recommend removing the loading attribute from it.”

The official Lighthouse 8.4.0 developer page describes the new functionality:

“Detect when the LCP element is lazy-loaded. Above-the-fold images that are lazily loaded render later in the page lifecycle, which can delay the largest contentful paint.”

New Mobile Viewport Audit

Lighthouse 8.4.0 will also add a new audit that detects if no mobile viewport meta tag in the head section.

This is important because failure to add this meta tag can result in a lower First Input Delay score.

The documentation explains the importance of this new audit:

“In a recent study of data from the HTTP Archive, over half of the sites that received a score of 90 or higher in Lighthouse, but failed at least one Core Web Vital, did not have a mobile viewport set and were failing FID. As a result, the Lighthouse performance section will now recommend adding a viewport like the following if none is found:

<meta name="viewport" content="width=device-width">"

Lighthouse 8.4.0 is Live

Lighthouse 8.4.0 is now live in PageSpeed Insights and will trigger the new LCP warning if it finds a lazy loaded element in the Largest Contentful Paint viewport.

Chrome Dev Tools will feature Lighthouse 8.4.0 in Chrome 95, which is currently scheduled for release on October 19, 2021.

Facebook Faces Yet Another Outage: Platform Encounters Technical Issues Again

Facebook Problem Again

Uppdated: It seems that today’s issues with Facebook haven’t affected as many users as the last time. A smaller group of people appears to be impacted this time around, which is a relief compared to the larger incident before. Nevertheless, it’s still frustrating for those affected, and hopefully, the issues will be resolved soon by the Facebook team.

Facebook had another problem today (March 20, 2024). According to Downdetector, a website that shows when other websites are not working, many people had trouble using Facebook.

This isn’t the first time Facebook has had issues. Just a little while ago, there was another problem that stopped people from using the site. Today, when people tried to use Facebook, it didn’t work like it should. People couldn’t see their friends’ posts, and sometimes the website wouldn’t even load.

Downdetector, which watches out for problems on websites, showed that lots of people were having trouble with Facebook. People from all over the world said they couldn’t use the site, and they were not happy about it.

When websites like Facebook have problems, it affects a lot of people. It’s not just about not being able to see posts or chat with friends. It can also impact businesses that use Facebook to reach customers.

Since Facebook owns Messenger and Instagram, the problems with Facebook also meant that people had trouble using these apps. It made the situation even more frustrating for many users, who rely on these apps to stay connected with others.

During this recent problem, one thing is obvious: the internet is always changing, and even big websites like Facebook can have problems. While people wait for Facebook to fix the issue, it shows us how easily things online can go wrong. It’s a good reminder that we should have backup plans for staying connected online, just in case something like this happens again.

We asked ChatGPT what will be Google (GOOG) stock price for 2030

We asked ChatGPT what will be Google (GOOG) stock price for 2030

Investors who have invested in Alphabet Inc. (NASDAQ: GOOG) stock have reaped significant benefits from the company’s robust financial performance over the last five years. Google’s dominance in the online advertising market has been a key driver of the company’s consistent revenue growth and impressive profit margins.

In addition, Google has expanded its operations into related fields such as cloud computing and artificial intelligence. These areas show great promise as future growth drivers, making them increasingly attractive to investors. Notably, Alphabet’s stock price has been rising due to investor interest in the company’s recent initiatives in the fast-developing field of artificial intelligence (AI), adding generative AI features to Gmail and Google Docs.

However, when it comes to predicting the future pricing of a corporation like Google, there are many factors to consider. With this in mind, Finbold turned to the artificial intelligence tool ChatGPT to suggest a likely pricing range for GOOG stock by 2030. Although the tool was unable to give a definitive price range, it did note the following:

“Over the long term, Google has a track record of strong financial performance and has shown an ability to adapt to changing market conditions. As such, it’s reasonable to expect that Google’s stock price may continue to appreciate over time.”

GOOG stock price prediction

While attempting to estimate the price range of future transactions, it is essential to consider a variety of measures in addition to the AI chat tool, which includes deep learning algorithms and stock market experts.

Finbold collected forecasts provided by CoinPriceForecast, a finance prediction tool that utilizes machine self-learning technology, to anticipate Google stock price by the end of 2030 to compare with ChatGPT’s projection.

According to the most recent long-term estimate, which Finbold obtained on March 20, the price of Google will rise beyond $200 in 2030 and touch $247 by the end of the year, which would indicate a 141% gain from today to the end of the year.

Google has been assigned a recommendation of ‘strong buy’ by the majority of analysts working on Wall Street for a more near-term time frame. Significantly, 36 analysts of the 48 have recommended a “strong buy,” while seven people have advocated a “buy.” The remaining five analysts had given a ‘hold’ rating.

The average price projection for Alphabet stock over the last three months has been $125.32; this objective represents a 22.31% upside from its current price. It’s interesting to note that the maximum price forecast for the next year is $160, representing a gain of 56.16% from the stock’s current price of $102.46.

While the outlook for Google stock may be positive, it’s important to keep in mind that some potential challenges and risks could impact its performance, including competition from ChatGPT itself, which could affect Google’s price.
