Let’s try to figure out exactly what the new metrics from Pagespeed are. There are six of them! Each of them has a different impact on the final assessment of the project. Consider them in sequence from most important to least important.

1. Load time for interaction

The most important indicator. It implies the amount of time for which the page being opened will be fully prepared to interact with the site visitor.

The metric believes that the page is prepared for interaction after:

• it is fully displayed
• an event handler was registered for virtually all parts visible to the user
• The response to the action performed by the visitor takes less than 50 ms

In short, the metric will positively evaluate the site, if the page is well loaded, its work does not “slow down” and it is ready to respond to various actions of visitors.

2. Download speed index

The metric allows you to understand how quickly the content is ready for viewing. To obtain estimates, a separate Speedline module has been developed. That is, this is the time interval for which the page opened in the browser stops changing.

3. The time required to download the first part of the information

This can be either a text block or an image, a photo, an infographic. Any content.

4. The end time of the CPU

The essence of the metric is to establish how long the mainstream of the page will be free for the ability to process manual input:

• almost all available elements are interactive
• the page responds to actions performed by the visitor for an adequate period of time
• the real response does not exceed 50 milliseconds

In short, this is about when the page is already generally able to respond to various actions, although its loading is not over.

5. Loading time of the main filling

This metric indicates how much time is needed so that the user sees the main content of the page. The moment of such loading comes:

• after loading all fonts
• after the main change in the appearance of the page

6. Approximate delay when entering

This indicator is the least significant. Evaluates the time in milliseconds required for the page to react to a particular visitor action during the busiest five seconds of the page load

If the indicator is more than 50 milliseconds, the visitor feels that the resource is “slowing down”.

Google Pagespeed Insights: what awaits us

In fact, the Google Pagespeed Insights update carries a lot of useful and interesting.

To begin with, the old metric brought not only benefits but also a negative. Forced recommendations do not carry anything good. Believe me. The recommendations are still general. They could be ineffective in a separate case.

The second is the introduction of specific recommendations could harm more important indicators. Although webmasters had no choice. They had to implement all the “tips” of the service.

After the introduction of new metrics, algorithms for evaluating and analyzing the site, most of the useless tips will simply fall off. And fly away like confetti on a Christmas party. Now the really important points are of particular value:

• the real server response rate
• volumes of “heavy” content on the page

The final assessment will be adversely affected by such additions and sometimes absolutely unnecessary things, such as:

• social network widgets
• interactive maps
• online chat rooms with consultants
• such beautiful and loved by many webmasters pop-ups

Therefore, the update Google Pagespeed and is considered revolutionary for site building. It is likely to provoke really quick projects. It will also help in understanding which sites to do. Well, personally, I really hope so! For Upcoming Trends of SEO in 2019 Check this.
