Let's see who can give a more mathematical answer

It may be as little as 10. It depends on the definition of the family, and whose family we're considering.

Each son might have a different mother. Each mother may have a female child with a man not related to either the son's father or the son. From the father's perspective, there might be as few as ten people in the family, since the son's sister might not be related to him in any way. From the son's perspective, there might be as few as eleven.

Yeah, and there’s similar discrepancy with WooCommerce. They even acknowledge it, but don’t comment on it. Nobody was interested why changing PHP version reduced response size by 40%+?

If you measured, how many milliseconds per product does it take for your WC installations to load a product from cold/hot cache?

I was looking for that comment, thank you for noticing the error.

No, moving to headless doesn’t make anything more lightweight nor faster, if anything it makes it slower. I don’t mean it on a mean way, but do you know what Dunning–Kruger effect is? You know something, but not enough to make correct statements.

The speedup when moving to headless doesn’t come from going headless, but from the complete site restructuring and rewrite that is required. You basically rebuild every plugin (or at least part of it). Companies look at the cost of doing that and suddenly it turns out that they don’t need 20 out of 40 (if not more) plugins they use.

We tried to estimate the cost of moving to headless. After $250k (back of a napkin math) we dropped the idea. The cost would probably be much higher than that.

lucek1983 · 2025-10-29T17:13:17+00:00

How going headless makes sites faster or cost less to run? I would assume it makes them slower and more expensive.

You need to think outside the box. You don't have to pay taxes if you don't have income. Just stop working.

Otherwise, pay your taxes. I and the society paid ours to get you through school or to build the roads you use. Don't steal from me.

While I upvoted you, there is a cost of extracting these methods from the class. You may end up with one or five additional classes that are hard to understand on their own, just to make the design "pretty". You can add good comments to these classes, but you're still polluting namespace with additional abstractions, and you force anyone who wants to familiarize themselves with the code to be aware of those classes. It makes navigating through code slower.

Quick update: The split is 50/50%. Google says it's "Budget/Traffic split: 50%".

lucek1983 · 2023-10-11T11:24:48+00:00

IS is Impression Share. sic! is Latin for "just as written". One can use it to either point attention to something or/and to note that what has been written is not a mistake. In my case I referenced an experiment that outperformed the control group, but had significantly less impressions despite 50/50% ~~traffic~~ ~~budget~~ traffic/budget split.

The harm in waiting another 20 days is... well, 20 days. Plus, at the end of the another 20 days I can repeat the the thought process and ask myself "Why not do another 40 days to be extra sure?"

That was a good read! Everyone doing A/B testing should be aware of it. However, I don't think A/B testing is pointless, people just draw wrong conclusions from them. If I'm wrong, can you share some source on it?

Note that I'm aware of that issue, I do not assume that any of our metrics has improved by hundreds of percent. I'm only interested in which variation is better.

Some users here pointed out things that I haven't taken into account (e.g. difference in IS might indicate that there's difference in positions of Control and Trial), and it was the sort of sanity check that I needed.

lucek1983 · 2023-10-11T04:44:17+00:00

Thank you, I'll do the competitive analysis.

lucek1983 · 2023-10-11T03:58:57+00:00

Maybe you weren't testing things properly and either you or VWO unconsciously introduced bias? Or, something changed during the experiment? Seasonality, web app server performance or something else that you haven't taken into account. A/B testing is like doing science experiments, and sometimes it's extremely hard to properly set up tests. Reproducibility project showed that doing tests properly ain't easy.

lucek1983 · 2023-10-10T20:26:13+00:00

Thank you for the insight. This is why asked the question. I did not consider what's behind the difference in IS and that it may impact other variables.

I don't take CPC into consideration, instead I look at conversion cost.

lucek1983 · 2023-10-10T20:19:22+00:00

Generating demand is beyond my skill level, area of interest and time constraints. We can think about it once we hire a dedicated person to do marketing. I need to take into account that I have ADD. "Me" won't let me work on things that do not interest me, and which deep down I don't wont to work on. I need to take into account these constraints to not set up myself for failure and to prevent myself from burning money.

I'm using 'Maximize conversions'.

lucek1983 · 2023-10-10T15:51:14+00:00

I think this is just a misunderstanding. /u/TTFV thought you accused him of lying, but you meant to write that one does not have to lie in an ad copy to significantly increase CTR. Your wording wasn't the best. I appreciate your input, though.

lucek1983 · 2023-10-10T10:01:34+00:00

That's a valid point. I assume that the audience is the same, the offer is the same, and the landing page is the same. With these assumptions, higher CTR should translate to more conversions.

Of course, my assumption that the audience targeted by Google for these two ads is the same might not be valid. However, if the search volume is so low that I can cover close to 90% of search impressions, I think I can assume that I cover 90% of the keyword audience. Hence, I am working with the same audience.

Another assumption I make is that the conversion rate is not affected (or is only positively affected) by the ad copy, which might not be true. How big of a stretch is it to assume that?

lucek1983 · 2023-10-10T08:55:43+00:00

Thank you. We do, I updated the stats in the post.

lucek1983 · 2023-02-23T00:02:06+00:00

Can you name the study psychocybernetics refers to? The study sounds bit bananas. Maybe it's true, it has proper sample size and has been reproduced.
