My Pages are getting Deindexed

Hi, I see there is a view on this link from RankMath.

Let me send a more detailed message which I sent by email before. It’s more comprehensive and you’ll understand my situation better. There may be variations in the tenses and other aspects. I sent the message before the issue of deindexing came up.

Here’s the message:
———————————————————————————
I have a new website (expired domain) I got recently and I’ve been
writing some articles. The website is in the parenting niche. I
restored some of the articles I could find from archive and then
started publishing new articles.

Particularly, I am starting on a niche basis and beginning with the
baby product segment. I am starting with baby car seats.

So far I have written some articles on car seat laws. From what I
learnt so far in gaining authority and ranking a page, one has to
interlink to relevant pages. Since car seat laws in the United States
are different across the States, I wrote individually for each states,
but before that I wrote a very long page on all the states but in
summary, just bullet points.

Now I have covered around 30 states in 2 batches in about 2 months. I
linked back to the parent page from all the individual states, making
it over 30 links to that page and been the oldest it is ranking for
several keywords but still very deep in the SERP.

From my GC, I noticed that the parent page is ranking for my focus
keywords for those other states. My plan was for the parent page to
only rank for “state car laws” and the other pages rank for “colorado
car seat laws,” “vermont car seat laws” etc. But the reverse is the
case. The parent page is ranking for each of this state’s focus
keywords while the states are ranking for other low search keywords.

My concerns are much.

Will there be competition in the SERP between the parent page and each
page for the focus kewwords I want for the other pages?
Will it lead to keyword cannibalization?
Will those state pages be able to rank at all eventually while the
parent page stop ranking?
Is there what I can do to make the parent page stop ranking?

I have removed the linking from the recent 15 articles I published in
a week and still left the old links that are almost a month or more so
to reduce the strength going to that parent page, but I don’t know if
it’ll have any effect.

Also, I had to include my focus keyword in the slug for the new pages.
the parent page is carrying “/car-seat/laws”

while the state pages are carrying “/car-seat/laws/colorado” etc
but the new pages now are carrying “/car-seat/awaii-car-seat-laws”
I fear for cannibalization this way but I was thinking this may force
Google to recognize them this way instead of the paremt page.

I was almost thinking of deindexing the parent page as well. It is
currently the page with the highest impression on daily basis and is
growing gradually. But instead of the queries to be from the
individual pages it is coming from the parent page.

I know this message is already long. Thank you or getting tp this point.
I think I will stop with the several worries and questions. I trust
you can assist me from this point and even point me to right direction
on what to do and expect.

Oh yes, I just remebered.
When I started, I checked competitors and 2 of them had a parent page
which made me toll that way.
It was after these happened that I went back to check the pages again
and saw that one 800 (https://www.800bucklup.org/car-seat-laws/)
didn’t mention about any state laws on the parent page but other
general information about basics on car seats and then linked down to
the various states that has the laws. While the other
(https://safeconvertiblecarseats.com/safety-resources/) used the
parent page as a category page where all the states laws are also
present but this page is not ranking. I don’t think the page has a
noidex tag.

These states car seat laws brings in decent traffic for these
websites. That is why I want my individual pages to rank instead of
the parent page which is not relevant per say.

The parent page is https://parentingwithhumility.com/car-seat/laws/

I anticipate your response.
Warm regards.

It seems you didn’t understand my messages.

I explained in details to you in the first and second message, but your reply doesn’t seem to fill in the void I’m try to understand.

If 8t wouldn’t be much trouble, kindly read the second message first and then the first.

I don’t want that main page to rank in place of the child pages.

Google started deindexing the child pages.

Since I don’t want the parent page to rank, I asked you what should be the best option.

On the other hand, I set the parent page to noindex so it stops ranking and allow the child pages.

Please read my messages again, and help me further.
Thank you for your support.

Thank you for your time further, it’s clearer now.

Thank you for the insights you gave in the third paragraph also

If it wouldn’t be too much to ask, please can you help me with a ‘not so formal’ audit of my website at the stage it is right now?
I bought the domain (parenting niche) as an expired domain and it had some backlinks which I can’t really tell if they are quality enough or not. I restored as many of the old pages The DA from Ahrefs, Moz, Semrush, and Ubersuggest are quite different, with Ahrefs showing less than 5 and the others averaging at 16. Looking at the SERPS my competitors have from 20-30 which gives me little confidence that I may have a chance.

– 800bucklup.org

In my ability so far, in the articles I’ve written so far, I’ve tried to write better articles than my competitors and I still have more to write.
(NB: I am starting with a niche/category and will be building up to other categories over time)

Please, I’ll appreciate a not-so-formal audit on my site and your assessment based on the list of factors you gave.
This is my first time building a website for SEO so all the technicalities are still overwhelming but I have been learning much from courses, SEO-focused websites like Backlinko, Neil Patel, and RankMath resources, and YouTube videos also.

I anticipate your kind response.
Warm regards.

Thank you very much for your help.

Warm regards.
