The Chrome User Experience Report is a public dataset of key user experience metrics for popular destinations on the web. It takes into account how Chrome users experience things in real-world conditions.
Lighthouse is an open source automated tool and part of Chrome Developer Tools. It allows you to audit the quality (performance, accessibility, and more) of web pages.
PageSpeed Insights is the tool we often use at MD. It tells you how well a page performs in the Chrome UX report. Its suggestions for performance optimizations are very useful.
From MD we would like to recommend a fourth r peru mobile database esource: GTmetrix . It is a free tool that allows you to analyze the loading speed of a website, and it does not depend (like the three resources recommended by Google) on Chrome.
A simple but necessary corollary to clarify: the Speed Update will not mean that a fast site will rise in the rankings per se . Since it is a penalty on slow sites, it is possible that a fast site will rise in the rankings but only at the expense of the sites that will be penalized. So, be careful! Don't let Today we want to explain how to track the indexing of sensitive PDFs and block their access to the Googlebot . Do you have no idea what we are talking about?
Once upon a time, there was a client who sold online courses. Because of poor website programming , Google robots indexed internal PDFs containing the lectures for those courses. What was the problem? Well, the client's sales were declining : the PDFs were to be given to users as a response to their queries, and the intention (obviously) was to get them to pay for them . Anyone could search for the PDF on Google and download it for free.
