Re: How Google Pagespeed works
#2> In July, the SEO ranking algorithm was updated to include page speed as a ranking factor for both mobile pages and ads.
What's one supposed to do when PageSpeed only points to Google's own asset delivery services as being "the" big problems which cause a lower score?
- "serve images in next gen formats" - complains about images served from tpc.googlesyndication.com
- "efficiently encode images" - same as above
- "reduce javascript execution time" - cdn.ampproject.org; securepubads.g.doubleclick.net; www.googletagservices.com
.. ?
I can easily get rid of those issues, "simply" by not showing any ads. The site will then be really fast, and... I'll get the ability to display ads again?!
Shame the ad-related revenue will be 0, which isn't unfortunately a good thing for the site.
Why is Google themselves not doing things "right" in order to ensure a speedy execution?
A while back, one of the reasons for a low score was that the GPT.js code (required to show ads) had a short expiration time. Dammit. How am I supposed to fix that, Google?

Hi! Author of the post here.
Lighthouse definitely has some improvements to make for the audit suggestions that offer advice to improve the score. I think people get a little bit frustrated/blinded by the advice when there's nothing that can be done about third parties (I know I do!).
Our product Calibre (mentioned in the bottom of the post) has a n adblocking/third party blocking feature that allows you to compare your pages with or without third party scripts gunking up performance metrics (here's the release post: https://calibreapp.com/blog/release-notes-apr-2019/).
We've seen really good success in separating the two because it sends a clear signal of what a site WOULD score without ads. This is good because it makes it clear to PMs, management and decision makers that tracking tools incur a really visible cost.

… but to answer your question better. It sucks that Google's own services don't live up to the performance expectations of tools made in other parts of Google.

#5If the weight of "Estimated Input Latency" is zero, why is it even mentioned?

Because it's in the code and it's factually correct. It felt weird to not mention it!

#7It's hard to take this blog post seriously when there is not one but THREE open Github issues which poses a serious question about the credibility of this whole pagespeed circus. It's just fundamentally wrong to claim that pagespeed speed score is based on the Lighthouse speed score when hundreds of people are reporting otherwise and even Lighthouse is suspiciously silent on this matter.

Hi, I'm the author :-)
I've left significant levels of details about pagespeed on the lighthouse issue tracker over the last few months. It's really frustrating to see the lighthouse team being blamed for something that isn't operationally even theirs… but that's a big company for you.
The biggest contributing factor to unstable pagespeed scores is the power of the machines that do the tests. Last time I checked the scores / bench mark scores for pagespeed were all over the place. … All the same, it's really important to understand how it all works. Hopefully the post had something for you?

I imagine the various teams at Google see each other as competition more than we might realize. How many chat-like applications are there? How about the Java/Kotlin Android teams versus the Flutter team? All of the GPL die-hards looking at the non-GPL (MIT, BSD, and Apache2) Fuchsia project wondering just how committed Google is to the Linux kernel.

if google could gain a market advantage similar to the one they got from linux (for free) they would do so immediately no matter the "cost" to linux/OSS/the-world-at-large
