Line 1: Disassemble problems with the greatest content painting: analysis and solution

Barry Pollard, Google Chrome's web productivity expert, explained how to identify the true causes of the bad Lowest Contentible Paint (LCP) and how to fix them. LCP is a key web vital that measures how long it takes to display the largest content element in the site of the site visitor (the part that the user sees in the browser). Content item can be an image or text. For LCP, the largest content items are HTML block elements that occupy the most places horizontally, for example, paragraph

, headings (H1 - H6) and image(Almost all HTML elements that occupy a considerable horizontal space).

"A mistake often made by publishers and SEOs after PageSpeed ​​Insights (PSI) indicates a page because

🚀 Polllard recommends staying on PSI, as it provides several tips on understanding the problems that lead to poor LCP work. It is important to understand what data the PSI gives you, especially the data received from the Chrome (Crux) user experience that comes from anonymous estimates by Chrome visitors. There are two types: URL data and source data.

• 📌 URL data is an estimate for a specific settling page. Source level data are generalized grades from the entire website. PSI shows URL data if there was enough traffic to the URL. Otherwise, it will show data at a source level (a generalized indicator for the whole site).

Polllard recommends looking at TTFB (time to the first byte) because, in his opinion, "TTFB is the first thing that happens to your page."

"Slow TTFB essentially means one of two things: 1) It takes too long to send a request to your server 2) Your server is too long. But determine what it (and why!) Can be difficult, and there are several possible reasons for each of these categories."

🚀 Polllard continued its review of LCP debugging with specific tests described below.

🚀 Barry finished his discussion, advising that the problem can only be corrected after it has been tested for recurrence.
