Google reported about the changes in the new version of the website analysis tool PageSpeed Insights (PSI). The developers have changed the engine to check the technical part of the Lighthouse. In this case, the data on site usability, the tool receives from the Chrome User Experience Report (CrUX). The company also announced the discontinuation of support for outdated versions of the PSI API in the next six months.

Google shared the information that you can get thru PageSpeed Insights:

  • Lab Data. PSI fetches and analyzes the page using Lighthouse, which simulates how a mobile device loads a page. It computes a set of performance metrics for the page (such as First Contentful Paint and Time to Interactive) and summarizes these metrics with a performance score from 0-100. Scores are categorized into three levels; 90 and up is considered to be a good score.
  • Field Data. PSI also displays real-world performance metrics (First Contentful Paint and First Input Delay) for the page and its origin. (As a result, we've also deprecated the origin: query in PSI). Note that not all sites may have field data available for display. The data set relies on a version of the Chrome User Experience Report that is updated daily and is aggregated over the previous 28 days. Keep in mind that the metrics here may be different from the ones in the Lab Data section as they capture a wide spectrum of real-world network conditions and devices used by Chrome users.
  • Opportunities. PSI provides suggestions on how to improve the page's performance metrics. Each suggestion in this section estimates how much faster the page will load if the improvement is implemented.
  • Diagnostics. This section provides additional information about how a page adheres to best practices for web development.

Google announced changes in the rules for sites ranking in the mobile search results in mid-January 2018. In this regard, the company recommended that you familiarize yourself with the tools of PageSpeed Insights and Lighthouse. Updated search algorithm earned in early July 2018.

At the summit of developers Chrome Dev Google representatives briefly announced the imminent opening of the registration of names for the top-level domain .dev. Application acception will begin in January 2019.

From January 16 to February 19, 2019, brand and trademark owners will have the opportunity to register a domain name with their trademark. From February 19 to 28 there will be an early access stage with a higher price. And from February 28, access will be open to anyone.

As noted, the .dev domain, like the previously opened .app, will receive support for the HTTPS protocol by default. A more detailed description of the domain zone is available on the official website.

In May 2018, Google announced the public registration in the domain zone .app - in the first top-level domain, which allows only secure connections. And in October 2018, early registration began in the .page zone. Unlike .app and .dev, which are designed for developers, the .page zone is focused on personal pages, business and thematic sites. The domain also supports only secure channels.
