I wasn't involved with this, but since you asked for feedback, I'll share some personal opinions:
If you're asking how to improve the questions, one way would be to flesh them out.
It might be helpful if the questions stated the requirements more explicitly. When I see a very short question, I often start to wonder if maybe there are some requirements that ...
You're asking about how 'good' a specific question will be perceived. That's not a question on how to use a website in a specific function.
if you'd asked "How do I ask a question or how do I create a poll on reddit" - then it's on-topic.
Furthermore you state
Please give an example to prove your point.

I put the question on hold. Please see the Help, but specifically:
Don't ask about...
Creating or developing a web application
Your other question was marginally okay, because it was asking about how to use the web interface of a particular feature, but a general question about something solely related to writing web applications is ...
It's actually not that bad - here're some stats;
193 migrations in the last 90 days
superuser.com → webapps.stackexchange.com × 97; 16% rejected
programmers.stackexchange.com → webapps.stackexchange.com × 2
From Meta Stack Exchange:
Starting [December 10, 2016], these should be deleted automatically 30 days after being rejected.
Note that this logic will only delete a rejected, migrated question if it meets the following criteria:
Migrated from another site (and no moderator has cleared the migration history)
Not already deleted
Closed (but not as a duplicate)...
The guidelines for the site's scope have not changed in the intervening time. Please see Make all recommendation questions out of scope and off topic, regardless of research as to why questions asking to recommend a website are off-topic, regardless of whether you included which sites you have tried already.
As was also mentioned in comments on the ...
It should not be re-opened as nowadays it's an off-topic question, actually it already has 2 delete votes. If it receive one more, it will be deleted.
IMHO the best way to proceed is to post a similar question on Software Recomendations.

How to download this webpage? is now closed.
Bearing in mind that this was over 5 years ago now, it's safe to say that the question likely fell through the cracks or was considered to be on the borderline at that point.
Our site has certainly evolved drastically from what it once was, so there is going to be this type of situation now and again. Overall,...
Generally, if both questions have answers, we want the "master" to be the better question with the better answers. The date shouldn't matter.
In this particular case, I think it's pretty much a toss-up. I think the question marked as a duplicate has a little more detail, but I think the accepted answer on the "master" is better.
Since the purpose of ...
Asking for app recommendations is no longer on-topic on this site, and hasn't been for some time.
If you are looking for a recommendation for a web application, and not a web site, then Software Recommendations is the place to go. Do be sure to read their Help Center, though, because they have stringent requirements for questions.
Tl;Dr: Webmail apps that were retired like Google Inbox are off-topic, those that are available are on-topic.
The comments on the referred the question include some hints about what happened in this specific case:
Inbox by Gmail was retired in April, 2019 and is no longer available.
I think that this text was added as a custom close reason, then some "...
Yes, the referred question is off-topic on this site.
While nowadays it's very common that popular "web applications" have a mobile app, this site's scope doesn't encompasses all the front-ends, it's only about using such web applications.
Even on applications like Instagram, WhatsApp and other software as services which their main functionality is ...
Your question should really have been asked on Maths meta as it concerns that site. While we are here to help you with questions about websites, questions about other sites on the Stack Exchange network are effectively off topic as we have dedicated sites (the meta sites) for each main site.
Rather than migrate it there though it's probably best if you ...
We also used to have a custom canned response for "dead" web apps

Talk about red herrings!
No. IMO, showing research in the question body is not a requirement when posting a question on WebApps SE.
You imply that your question on Webapps SE was closed because of a comment asking for a description of your research. Regrettably you chose not to disclose the actual reason given for closure. And since your question has since ...
Just because a person when they write the question places labels on the question, doesn't automatically mean that labels applies.
While it is expected that they might miss a label, or they may not be sure if they should specify gmail or gmail-labels or gmail-filters, there are times where they put a label on the question that clearly doesn't apply.
So if the ...
Yes, the OP must state that they are using the web site version of the application.
A big reason for this is that the web site version might have different features to the desktop or (more likely) smart phone version of the application so asking a question about a feature that isn't available on the website, or is implemented differently, will cause ...
ChrisF nicely explains why it was off-topic (not about a web app, but a protocol).
For a little more help on what could have been done to get the question re-opened, though (to fully answer your question), you could have:
