How well is the Semantic Core composed?

Question

Search Engine Optimization

Links to the semantic core and structure (based on the given SL).
Here's what I did:
1. Collected phrases in the key collector from almost all available sources.
2. Weeded out stop words and deleted the phrases corresponding to them.
3. Weeded out irrelevant, non-targeted, erroneous requests.
4. Made a grouping.
5. Collected SA.
Additional comment:
- In the core, you can see that some queries for exact match ("in quotes") according to J.Wordstat have zero values. I left them, since the task is the first positions not only in Yandex, but also in Google, Rambler, Mail + additional traffic.
This is my first real SA. Give, please, your assessment, recommendations. This will be very valuable to me.

After your recommendations, I realized that I deceived myself and everything is a little more complicated than I would like to :) I
will analyze my further actions using the example of one page from SL.
--- --- --- --- --- --- --- --- --- --- --- ---
Topic 1. It is inefficient to promote one page for commercial and non-commercial queries.
I checked in Yandex PS for each phrase from this list belonging to commercial and non-commercial. Here's what happened (screenshot below).

In principle, what to do with these information requests is clear. Sort of :)
And so I removed (for now) information requests from this page.
Now the question pops up - what to do with rubble? The fact is that there will be a separate core for the phrase "rubble", the site sells not only sand. What do you usually do in such a situation - delete all such requests or do something else?

I will remove the rubble for now, just in case, to the side. Here's what's left (screenshot below).
Topic 2. One page should contain requests from one search group.
The theme of the page in question is "construction sand". After analyzing the correspondence of the remaining queries to one search group, I highlighted a phrase that does not fit into this search group.
The phrase "building sand average price" refers rather to a page with the topic "building sand average". This can be seen from the structure, sinceconstruction medium sand is a kind of construction sand. That's why I'm sending this request there.

And here is the result (screenshot below).
What didn't I learn? :)

Judging by your answers, I understand that everything is in OK with my previous analysis. But there are still questions that baffle. Please share how you solve these issues.

A little earlier, I talked about removing the sand from the building request page "natural construction sand". This query matches the meaning of the search group on the page natural sand . (screenshot below)

And then the question arises:
In the text , the phrase "natural building sand" is suitable for both the building sand page and the natural sand page .
In terms of meaning , the phrase "natural building sand" is suitable for the page natural sand , because. natural sand is a type of building sand .
If I just put this phrase on the corresponding page ( natural sand ), won't these 2 pages ( natural sand and construction sand ) interfere with each other's promotion?
How to be in such a situation?
--- --- --- --- --- --- --- --- --- --- --- ---
After parsing the entire SA for division into pages with commercial and informational requests, as well as division of pages into search groups, the following happened - look at the table .
--- --- --- --- --- --- --- --- --- --- --- ---
Sheet 1. The process of separating queries (and pages) into commercial ones (blue ) and information (green).
Sheet 2. The result of the separation.
Sheet 3. Combining requests for building sand and buy sand into one page.
Sheet 4. Added requests (which were initially identified as unsuitable in 1 sheet of the document) "in their places", unsuitable - removed.
And here remains the last question: I broke the page natural sandfor commercial and non-commercial inquiries. I got 2 pages - natural sand and natural sand buy .
Is it logical to do so in terms of site structure?
By the way, this is how she began to look now (screenshot below)

Answer 1

In general, you did everything right.
> according to J. Wordstat, they have zero values ​​\u200b\u200bthis
is constant, I saw attendance of 30 people per day attendance from Yandex for keys with 0 value according to wordstat (and this is actually about 900 a month), so wordstat is not true, this is a landmark...
