How the Test has been run

With the help of Puppeteer, we have run lighthouse tests on multiple AWS regions with simulated network traffic. 63 test pages have been created based on script location, script injection method, Script Load Type, and Ad Unit Tag Type combination.

Code, Config and test pages are available on branch name year-pagespeed in folder test/pagespeed.

https://bitbucket.org/monetizem/m2hb/src/year-pagespeed/test/pagespeed/

Location

head
body start
body end

Script Injection

script tag (sync/async/defer)
embedded script (sync/async)
embedded wrapped in function (sync/async)

Script Load Type

sync
async
defer

AdUnit Tag Type

id – html div with id – <div id=”{slotId}”></div>
- limitation – can’t use same id multiple times

attribute – html div with custom attribute – <div class=”pg-ad” data-pg-ad=”{slotId}”></div>
pgtag – custom html tag – <pubguru data-ad=”{slotId}”></pubguru>

Device Type Simulated

desktop
mobile

Description of Metrics used in the Test

First contentful paint

First Contentful Paint marks the time at which the first text or image is painted.

Speed index

Speed Index shows how quickly the contents of a page are visibly populated.
Speed Index measures how quickly content is visually displayed during page load. Lighthouse first captures a video of the page loading in the browser and computes the visual progression between frames.

Total blocking time

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds. https://web.dev/lighthouse-total-blocking-time/

Interactive

Time to interactive is the amount of time it takes for the page to become fully interactive. https://web.dev/interactive/

Bootup time (JavaScript execution time)

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. https://web.dev/bootup-time/

Performance score

The Performance score is a weighted average of the metric scores. Naturally, more heavily weighted metrics have a bigger effect on your overall Performance score. The metric scores are not visible in the report but are calculated under the hood.

SEO score

These checks ensure that your page is optimized for search engine results ranking. There are additional factors Lighthouse does not check that may affect your search ranking.

Cumulative layout shift

Cumulative Layout Shift measures the movement of visible elements within the viewport. https://web.dev/cls/

Largest contentful paint

This is the largest contentful element painted within the viewport. https://web.dev/lighthouse-largest-contentful-paint/

First meaningful paint

First Meaningful Paint measures when the primary content of a page is visible. https://web.dev/first-meaningful-paint/

Conclusion

Based on average of performance score, time to interactive and speedindex I have found bodyEnd-embeddedWrapped-async performance better for desktop and mobile both.

bodyEnd-embeddedWrapped-async means javascript code to load script asynchronously is wrapped in function and placed at the end of body tag. Please check following snippet with example tag how it looks like.

<body>

(function(d){

var script = d.createElement(‘script’);

script.async = true;

script.type = ‘text/javascript’;

script.src = ‘//m2d.m2.ai/pghb.minecraftresourcepacks.js’;

var target = d.getElementsByTagName(‘head’)[0];

target.insertBefore(script, target.firstChild);

})(document);

</script>

</body>
